If you're in the market for an oil-filled radiator, it's important to consider the size before making your purchase. They can be one of the best radiators if you're searching for a portable option, but choosing the wrong one can negatively affect their efficiency and how comfortable your room feels.

These portable appliances come in a variety of sizes, ranging from small units with around 80W of power to larger models reaching up to 2500W. When selecting the right one for your home, you'll need to consider both the room size and the level of insulation.

To help you determine which size oil-filled radiator you should buy, we called in the experts to explain everything you need to know. Below, you'll find the calculations to make, how to tell if yours is the wrong size, and what can happen if it is.

How to size an oil-filled radiator

With a heat calculator:
To get the most accurate results, Nick Duggan, Managing Director of The Radiator Centre, recommends using an online heat calculator (like this one by B&Q) to determine your specific requirements. After entering your room’s dimensions and type of insulation, windows, and outside wall, the results will be shown in either watts or BTUs (British Thermal Units).

Nick says, "All radiators will state an output in either watts, BTUs or both. By knowing how much heat each radiator will emit, you can now find the best one to efficiently heat each room based on your earlier heat calculation."

Without a heat calculator:
If you prefer to work it out yourself, Nicholas Aukland, Managing Director of Trade Radiators, says to multiply the room’s square meterage by 100 watts for a standard ceiling height with average insulation.

For example: 20 m² room = 2,000 watts

However, if your room is poorly insulated or has particularly high ceilings, you’ll need to add around 10 to 20% on top of that figure. So, the example above would become 2,200 to 2,400 watts.

Nicholas adds, "Most radiator manufacturers will provide sizing guides and all models should list their output in watts so you can match the heater to the space with fairly little trouble."

How does the size of an oil-filled radiator affect efficiency?

If your radiator is undersized...
Nicholas Aukland explains that by choosing a radiator that’s too small for your room, you’ll end up running it on the highest setting for long stretches of time – after all that, your room will still feel cold!

Nick Duggan adds, "An undersized radiator leads to uneven heat, cold patches and higher electricity use because the appliance never gets a break."

If your radiator is oversized...
Bigger isn’t always better when it comes to radiator size; an oversized model can make the room heat up too quickly and feel uncomfortably stuffy. Nicholas explains that the thermostat will cut in and out repeatedly, and you’ll just end up switching it off because it feels too overwhelming.

Nick Duggan says, "An oversized one short cycles, which is inefficient and uncomfortable, and can create a humid, heavy feeling in the room that makes the space feel smaller. Getting the output right for the room avoids these issues and keeps the temperature stable without wasting energy."

Signs your oil-filled radiator is the wrong size

If you think your radiator is the wrong size, look out for these tell-tale signs, explained by Nicholas Aukland:

It's undersized if...

• You feel heat pooling right beside the unit while the rest of the room stays chilly
• The unit runs flat out for long stretches
• The thermostat rarely clicks off
• You feel you need to sit close to stay warm
• The fins feel very hot but the far wall or corners remain cool, which is often a mix of too little surface area and poor airflow

It's oversized if...

• You get rapid temperature rises and frequent thermostat clicks followed by short, repeated on‑off cycles
• The room can feel stuffy, then cool again a few minutes later
• You want to crack open a window to dump heat
• Overheat cut‑outs trip out

However, Nicholas adds: "Some of the same symptoms can come from placement, so check that fins are not blocked by furniture or drying clothes, doors are closed to stop heat escaping, and draughts are managed before deciding the size is wrong."

To prevent wasting energy, money, and time, it's important to choose the correct size before installing a radiator. By following these calculation tips and watching for the signs mentioned above, you can ensure your heater is the right fit.

If you're unclear whether an oil-filled radiator is the best choice for your home, explore the different heat emitters available, as explained by the experts.

If you're in the process of choosing a heat emitter, you might consider an oil‑filled radiator and wonder how they work. Renowned for their energy‑efficient and portable design, these radiators are a popular choice in many households and offer a number of benefits.

Oil‑filled radiators are a type of electric radiator and typically feature a plug‑in design. While some models can be wall-mounted, they are usually freestanding, making them easy to move from room to room.

Despite being a common appliance, few people know how oil-filled radiators actually work, so we've called in the experts to explain everything you need to know below. If you're curious about how they function, whether the oil needs topping up, or if they're worth the investment, keep reading.

How do oil-filled radiators work?

"Oil-filled radiators work by heating a reservoir of oil sealed inside the unit," explains Nicholas Auckland, Managing Director of Trade Radiators. "The oil is warmed by an electric heating element, and once heated, it circulates within the radiator’s fins. This stores and radiates heat steadily into the room."

Since this type of radiator doesn't blow air, it's quiet and comfortable for continuous use and is suitable for noise-sensitive rooms. According to Nick Duggan, Managing Director of The Radiator Centre, these heaters can stay warm for 30 minutes to over an hour after they’ve stopped drawing electricity, which is why they’re such an efficient choice.

Are oil-filled radiators any good?

Yes, oil-filled radiators are a good choice for heating small to medium-sized rooms, providing a steady, even warmth.

You can pick one up for around £30, and running costs can be as little as 15p per hour (based on current kWh rates with a 500W model). They’re an excellent way to heat a single room locally without having to turn on your central heating.

Unlike other portable heaters, such as fan heaters and convector heaters, oil-filled radiators are very quiet and are usually safe to leave on overnight, making them a suitable choice for bedrooms if you want an undisturbed night’s sleep.

While these radiators offer many benefits, whether they’re worth it will depend on your heating needs and preferences, explains Nick Duggan.

He says, "They may take longer to warm up, but their efficiency and low maintenance often make up for these drawbacks over time. However, if you need instant heat or have limited space, you might want to consider other options."

Pros and cons of oil-filled radiators

Before you install an oil-filled radiator, it's important to consider both the pros and cons. Here's what Nick Duggan wants you to know:

Pros

• Energy-efficient: As previously mentioned, these radiators retain heat well (even after they’ve been switched off), which helps you save energy.
• Quiet: Ideal for bedrooms and offices, you won’t be disturbed by fans or blowers.
• Consistent heating: Oil-filled radiators don’t create hot or cold spots, so you can enjoy an even, comfortable warmth.
• Hassle-free: Contrary to popular belief, you won’t need to worry about topping them up with oil or carrying out any maintenance.
• Safe and healthy: These radiators often come with safety features like tip-over protection and overheating prevention to give you peace of mind. Since they don’t dry out the air or consume oxygen, they help maintain good air quality too.
• Portable: Oil-filled radiators can warm areas of your home that a conventional heater can’t reach, simply because you can pick it up and move it wherever you need it.

Cons

• Slow to heat up: Compared to other emitters, you may have to wait a little longer for oil-filled radiators to warm up.
• Higher initial cost: While still generally affordable, oil-filled radiators tend to be more expensive than basic space heaters.
• Limited directional heating: You won’t be able to focus the heat in a specific direction.
• Bulkiness: They are often bulkier and heavier than other portable heaters, which might not be ideal for small spaces.
• Hot surface: Something to keep in mind if you have small children or pets – the exterior can become very hot during operation, which could result in burns if touched.

Do you have to refill oil-filled radiators?

This is a question Nick Duggan is asked a lot, but the answer is no – you don’t need to top up an oil-filled radiator with oil.

Nicholas Auckland explains that the oil simply acts as a heat reservoir, allowing the radiator to provide warmth without sudden temperature swings or frequent cycling.

If you don't mind the bulkiness and waiting a little longer for them to heat up, oil-filled radiators can be a great, energy-efficient choice for your home that doesn’t require complicated maintenance. Now that you have all the information about how they work, you can decide whether they’re right for your needs.

With heating bills soaring, everyone is looking for a simple way to cut costs – which is where radiator booster fans could come to the rescue.

For those who have never heard of them, these gadgets attach to the bottom or top of the best radiator, drawing in cooler air from the floor, blowing it across the warm radiator surface, and then pushing the heated air quickly around the room.

To find out whether these add-ons really work (or whether they’re just another gimmick), we asked a heating expert for their opinions and put them to the test on our own radiators. Keep reading to hear our final verdict and find out whether they’re worth investing in this winter.

How do radiator fans work?

According to Nick Duggan, Managing Director of The Radiator Centre, these fans will usually sit beneath or on top of your radiator and can help speed up how quickly a room warms up.

So how do they work? Nick explains, "Heat from a radiator is generated by cooler air passing over warm surfaces and convecting around a room. A fan will draw more of that cooler air through a radiator faster, potentially generating more heat in a shorter period of time.

"Fan systems often get coupled with radiators that are being installed on a heat pump. As the temperature of the water in this system is cooler than a standard gas fired boiler, having the fans helps get more heat from a cooler radiator."

Could radiator fans reduce my heating bills?

Yes, radiator booster fans have the potential to save you money on your heating bills.

Nick Duggan explains that since they help to heat your room more quickly, your thermostatic radiator valve will sense this and close off. As a result, you won’t be consuming as much energy as before, and therefore, it could reduce your bills.

However, it’s worth keeping in mind that radiator booster fans aren’t going to make your room hotter – they simply help the room reach its set temperature at a faster rate. If you want the temperature to increase, you’ll need to adjust this via your boiler and room thermostat.

My experience with radiator booster fans

I tested SpeedComfort's radiator fans (available on Amazon) in my kitchen and office, and found them very easy to install and extremely quiet, with a volume of just 22 dB – similar to the rustling of leaves.

If you're not sure how many fans you’ll need, the website has a handy quiz that works it out for you. I found this really helpful, as I wasn’t entirely sure myself.

One thing I will say is that they don’t look particularly attractive on a column radiator, and you’ll need to buy additional hooks so they can hang from the bottom (which costs £3.50 extra). However, given the potential savings on your heating bills (22%, according to the brand), this is something I’m willing to overlook.

I’ve been on a mission this month to find the best heating hacks, and I will say that I preferred the Radlek reflectors – a reflective sheet that sits behind your radiator to reduce heat lost through poorly insulated walls.

Where to buy radiator booster fans

Radiator fans won’t magically heat your home without energy, but if you want to speed up the process and reduce your bills, they’re definitely worth considering.

Oil-filled radiators are a popular way to warm up a bedroom or home office without switching on the full heating. They’re quiet, steady and generally efficient – which naturally begs the question: are they safe to leave on overnight?

Modern radiators come with far better safety features than older portable heaters, but there are still a few things worth knowing before you drift off to sleep with one running. Our helpful guide breaks down how these types of radiator are designed to be used safely, and the situations where a little extra care is required.

Are oil-filled radiators safe to use overnight?

In most cases, yes – a modern oil-filled radiator can be safe to leave on overnight, as long as you’re using a well-designed model and setting it up properly.

Licensed electrician and HVAC specialist David Miloshev from Fantastic Services explains that these heaters are built for extended use, thanks to a sealed heating element and slow, steady output. This design means there’s “no exposed coil, no open flame and no risk of the oil burning,” making them one of the safest options for long runtimes.

Gas Safe engineer Patrick Garner from Heatable agrees, adding that the lower surface temperatures on oil-filled radiators “reduce the risk of burns or ignition” compared with other portable heaters.

Both experts stress the same point: the heater itself is rarely the problem. Safety comes down to choosing a model with proper protections – such as overheat cut-off, tip-over protection and a good thermostat – and using it exactly as the manufacturer intends. When those boxes are ticked, they say overnight use is generally considered safe.

What are the risks?

While oil-filled models are considered one of the safest types of portable heater, overnight use can still be risky if the setup isn’t right. Both experts agree that the main issues stem from how the heater is used, rather than the appliance itself.

Improper placement is the biggest concern. David Miloshev warns that these heaters need plenty of breathing room, with ideally around a metre on all sides. Pushing one against bedding, curtains or piles of clothes can trap heat and cause fabrics to scorch. And Patrick Garner adds that draping clothes or towels over the unit is a common mistake that can quickly lead to overheating (so try drying clothes with a dehumidifier or tumble dryer instead).

You shouldn't overlook your electrical setup either. Miloshev strongly advises against using extension leads, power strips or multi-plug adapters, explaining that they can overheat under prolonged load and fail. He also notes that older wiring, buzzing outlets or warm plug sockets should be treated as red flags. In these cases, an overnight run simply isn’t safe until the electrical issue is fixed.

Ventilation and room size play a role. Using an oil-filled radiator in very small or enclosed spaces can cause heat to build up faster than the thermostat can manage. This forces the heater to work at full power for longer, increasing strain on its safety components.

Finally, don’t ignore visible wear and tear. Frayed cables, dented fins, loose wheels or a thermostat that cuts in and out irregularly all compromise the safety of a machine. As Garner points out, most problems arise “from misuse rather than the appliance itself” – so keeping the heater in good condition is important.

Used sensibly and placed with care, the risks remain low. But if any of these warning signs apply, it’s best not to leave the heater running while you sleep.

Safety tips for overnight use

If you do plan to run an oil-filled radiator while you sleep, a few simple habits can make a big difference to how safely it works:

1. Give it plenty of space Keep at least a metre around the heater and make sure nothing – especially bedding, curtains or clothes – can fall onto it. This helps the thermostat work properly and prevents heat from building up.
2. Use the thermostat and timer A built-in thermostat keeps the radiator from running flat-out all night, while a timer lets you set gentle background heat rather than continuous output. This reduces strain on the unit and saves energy.
3. Plug it directly into a wall socket Never use an extension lead or multi-plug adapter. As electrician David Miloshev explains, they can overheat under sustained load. A grounded wall socket on its own circuit is always the safest choice.
4. Check the cable and plug Look for fraying, kinks, scorch marks or a plug that feels warm during use. Any damage means the heater shouldn’t be used until repaired or replaced.
5. Choose the right room Oil-filled radiators work best in well-ventilated bedrooms or living spaces. Avoid very tight or enclosed rooms where heat can build up faster than the thermostat can keep up. Wobbly floors or uneven carpets also increase the chance of the heater tipping, even if it has tip-over protection. A firm, flat spot is ideal.

Portable heaters are handy for quick, targeted warmth, but long-term comfort comes from choosing the right heating system for your space. From skirting board heating to traditional radiators, explore which heat emitter suits your home best with advice from our experts.

Most radiators come pre-painted and factory-finished, so it makes sense that they are at their most energy-efficient. However, the original colour might not meet your design ambitions, or time has taken its toll, and a repaint is on the cards.

Even the best radiators will eventually need a makeover, and a new coat of paint is a very cost-effective way to update them. But the big question is, will the new paint affect the heat output? Here you’ll find what difference paint will make, which colour works well, and which paint to use.

Will the amount of paint coats on a radiator affect heat output?

When painting radiators, adding more layers of paint can affect the output of a radiator, but the reduction in output is typically minimal, as Viktor Velikov, Director of ELSERVE points out, “Each layer of paint adds a thin barrier that can slightly reduce a radiator’s ability to release heat. The effect is usually minor,” he adds, “But excessive build-up insulates the metal and lowers efficiency.”

It is worth noting that most standard radiators have three layers. “Most modern radiators leave the factory with three layers: primer to prevent corrosion, undercoat for adhesion, and a gloss topcoat for durability and appearance," he says. “These coatings are heat-resistant and applied thinly to preserve thermal performance.”

Try these paints and tools on a radiator

The best colour for heat output

The colour of a radiator has little effect on its heat output. Louis Georgiou, Operations Director, Essential Workwear, briefly explains why: “Radiators have traditionally been white just because it suits most interiors, not because it improves performance. In reality, the colour has very little effect on how much heat you feel in a room.” Good news if you want your wall colour to match your radiator – our tips on painting behind a radiator will help with that task too.

Jimmy Englezos, Senior Brand Manager from Ronseal also explains it's not really the colour that makes the difference. “A radiator’s heat output is actually more manipulated by the reflectiveness of its paint finish," he says. "Shiny surfaces such as chrome or stainless steel will reduce its overall heat output since the shinier surface reduces its ability to transfer heat to the surrounding air.”

How the finish affects the heat output

When painting a radiator, the finish can affect heat output, but, as already mentioned, the reduction is minimal, especially with traditional paint finishes such as gloss, satin, and matt.

Georgiou says, “Whether you go for gloss, satin, or matt, the heat output will stay virtually the same – the finish is more about aesthetics than performance. What really matters is the quality of the paint.”

According to Englezos, for an effective finish, use matt paint: “Matt finishes can improve a radiator's efficiency and heat output, with black being the most efficient colour choice since it absorbs all light wavelengths before converting them into other forms of energy, in this case, heat.”

While black is a good choice, there isn’t a big difference between colours, explains Englezos, “The specific change in heat output between matt black and other matt colours, e.g., white radiator paint, is only around 1%, so don’t feel like you have to stick to black to get the maximum efficiency.”

Paint to use on a radiator

Choosing the right paint for a radiator is key to a successful paint job. Englezos says, “It’s important to use the correct type of paint that is suitable for use on metalwork and can withstand temperature changes.” The easy choice is a radiator paint such as this Hammerite Radiator Enamel Aerosol from Amazon, as it’s specifically formulated for radiators.

You can use everyday wood/metal paints such as this Dulux Trade Satinwood from Toolstation. These are typically heat-resistant up to around 90 degrees Celsius but are prone to discolouration, especially light coloured oil-based paints.

Whether you're looking to update your hallway radiator ideas or want to refresh your living room radiators, painting them with a couple of coats of your favourite shade is a quick and cost-effective way to add a touch of style to a room without impacting how much heat you'll get from the radiators.

With rising heating bills and plummeting temperatures, many families are facing a difficult dilemma this year. I, for one, have been reluctant to turn on my heating because of the high costs and have been on the hunt for a money-saving hack that could make my heating go further.

So when I saw Radflek’s Radiator Reflectors on Amazon for only £20, I knew I had to give them a try. They might look like your average roll of kitchen foil, but the brand claims they can reduce heat loss by 45% and reflect 95% of the heat back into your room.

After learning more about how radiator reflectors work and how much they could potentially shave off my heating bills, I was eager to put them to the test.

Installing Radflek Radiator Reflectors

When the radiator reflectors arrived, I’ll admit I was pretty skeptical that they would do anything worthwhile. As I mentioned before, they just look like kitchen foil – but if Radlek’s heat-gain promises were true, I’d have to put my doubts to one side.

The package came with two sheets that could be trimmed to size, Radklips (which keep the sheets in place), and Radstik joining tape (if you needed to fasten the two sheets together).

Installation was very simple, and I had it set up behind my radiator within 10 minutes of opening the packet. The instructions were clear and included a diagram for each step, making it a breeze to follow.

Here's what you'll need to do:

1. Flatten the creases in the sheet.
2. Measure the distance between your radiator’s wall brackets.
3. Cut the sheet to this width.
4. Make a 1cm fold at the top of the sheet.
5. Slide the Radklips over the fold (I used three for one sheet).
6. Roll the top of the sheet around the Radklips.
7. Place the Radklips on the wall brackets behind your radiator, with the printed side facing the wall.
8. Trim or roll any overhang so it isn’t visible.

I was pleasantly surprised that you can't see it at all behind my radiator – though I did have to fold the bottom up slightly because it was a bit too long. However, for some types of radiators with large gaps or minimal side panels, they might be more visible.

How did the Radlek Radiator Reflectors perform?

To find out whether the Radlek Radiator Reflectors really work, I put them to the test in my bedroom. Before fitting the gadget, I made sure all doors and windows were closed and that my radiator was the only heat source in the room.

I set my thermostat to 21°C and waited until my room had reached this temperature, recording it using my Apple HomePod Mini and noting down the time.

I then installed the reflector behind my radiator and, after an hour and a half, noticed that the temperature had increased by 1.5°C (to 22.5°C) – without touching anything. After a further 20 minutes, the temperature rose by another 0.5°C , and in the next 20 minutes, by an additional 0.5°C.

I started at 21°C at the beginning of the test, and within two hours I’d boosted the temperature by a total of 2.5°C – pretty impressive considering I didn’t turn up the heating or adjust the dial. By this point I was roasting, so I decided to end my experiment before I sweltered away.

When I measured the room temperature without the reflectors, it didn’t increase.

Where to buy radiator reflectors

To conclude, I was very impressed with the results of the Radflek Radiator Reflectors and would highly recommend them to anyone looking for an affordable way to boost their home heating.

Nick Duggan, Managing Director of The Radiator Centre, adds, "While they won’t transform the performance of your heating system, they can make a modest but useful difference by cutting back on unnecessary heat loss.

"It’s best to think of them as a supportive measure rather than a standalone solution: good insulation, appropriately sized radiators and efficient controls will always have the biggest impact, but reflectors can certainly contribute to overall energy efficiency."

Although it's natural to hear the odd sound escaping from your radiators, noisy radiators can be more disturbing than you expect – particularly if you set them to come on early in the morning before you wake up.

But, are noisy radiators something to worry about or can you fix the problem yourself? Or, is the noise something you should accept, and in fact a sign that they are working as they should?

We asked radiator experts to help us tune in to when noisy radiators need to be listened to, what the noises mean and how we can get them to pipe down.

What do noisy radiators sound like?

There isn't one definitive description you can use for noisy radiators say the experts. Instead, it's a range of noises, some of which you may recognise from your own central heating system.

"Noises can range from gentle gurgles and hisses to louder banging, clanging or knocking," explains Nick Duggan, managing director of The Radiator Centre.

So, what do the different noises mean and when should we be worried? "A soft bubbling or trickling is usually nothing to worry about, while sharper or repeated bangs can indicate a deeper issue in the system," explains Nick.

"Even well-maintained heating systems can make a few sounds as they expand, contract or circulate water," says Nick, "but these may die down over time as the system finds its rhythm."

However, while most noises are easily rectified, understanding what each noise means and the reason it's happening can help you make sure your noisy radiators become quieter quicker.

Types of radiator noise, the causes and the solutions

According to John Klee, heating technology expert at BestHeating, noisy radiators in general make five different types of noise, and their causes can be categorised as follows:

1. Gurgling

“One of the most common radiator noises is gurgling and luckily this is a simple issue to fix," says John. "A gurgling sound indicates trapped air that is desperate to escape - having built up over time. It also means there are cold spots on the radiator, and the solution to this is to bleed your radiators."

"This is likely to have happened due to a lack of maintenance, radiators must be bled at least once a year to work efficiently during the winter months. Take the time to loosen the valves with a bleed key to release the air," says John. "You'll get rid of the noise and make radiators warmer, and more cost-effective.”

2. Banging

John says: “A banging noise is better known as ‘kettling’, which refers to a buildup of limescale within the central heating system rather than the radiators. If you experience this, it is recommended you turn off your heating system and drain the radiators to allow trapped air and water to escape, allowing the issue to be fixed temporarily.

"If the banging persists, then a heating system power flush could be needed sooner rather than later," he warns. "This will remove all grime and limescale from the boiler and increase the efficiency of your heating. Areas with hard water are more likely to experience this problem, such as the Southeast.”

3. Whistling and tapping

“If a whistling or tapping noise emanates from radiators, these sounds usually point to a basic error with thermostatic valves," says John. "When a radiator whistles, it signals that there is too much water flowing through them. A simple change – turning the radiator valve to full – should combat this.

"Newly installed radiators can also cause valves to tap," adds John. "It often points to loose components such as fittings or brackets within the radiator or heating system. To stop these noises, inspect the radiator for any loose parts and tighten where needed. If the tapping persists, then this could be due to a buildup of limescale within the pipes and radiators, so use a non-acidic cleaner to flush out the system, just make sure it is turned off first.”

4. Clicking and ticking

Although they may be annoying, commonly heard clicking and ticking noises aren’t dangerous, John reassures us.

“When your heating system is in use, often the noises that can be heard are natural. For example, a clicking sound is the result of expansion of metal as hot water flows into a radiator, so should be expected when the heating system is on.

"Similarly, a ticking noise often happens when radiators are heating up or cooling down but this is normal," says John. "There isn’t a way to prevent these but it’s good to have the knowledge that there isn’t an issue. Any noise will sound worse when there is silence throughout a home, but be rest assured that if you service a boiler yearly and feel toasty in bed, then it is likely that your system is working as normal.”

FAQ

When is a noisy radiator no longer fit for purpose?

Although most noises can be resolved, there may be times when you need to replace a radiator confirms Nick Duggan.

"Sometimes, if a radiator is very old, heavily corroded or beyond practical repair, replacement is the most effective solution. It’s rare, but when maintenance no longer restores performance or the radiator is prone to leaks, a new radiator can bring peace of mind."

Cosy bedrooms can be achieved in a number of ways, with bedroom radiator ideas one of the most obvious and practical methods for creating a warm place in which to slumber.

But with all the different types of radiator available, how do you choose one that doesn't just suit your needs, but also matches the look and feel of your relaxation room?

From small to large plus traditional styles to those that are a little more unusual, here's 11 bedroom radiator ideas that will give you the best ending for your bedtime story.

1. Use window shutters so the heat can easily reach your room

Although we'll showcase bedroom radiator ideas that provide you with the opportunity to turn it into a stand out feature, rather than one that shies away from attention, there are still practical considerations to take into account when heating a bedroom.

“Heating choices for the bedroom differ slightly to those in more social spaces," confirms Nancy Emery, heating expert at Drench. "While performance is still important, these rooms, which are generally smaller, usually require lower heat output than living area."

But, that heat is still important, so when smaller radiators are specified, "avoid positioning radiators directly behind beds or heavy furniture and leave curtains clear to maintain airflow," she suggests.

One solution I'm a fan of for bedroom window ideas? Window shutters. They cover my sash windows well, but leave the small, low-level radiators below unencumbered and free to radiate heat outwards and upwards.

2. Pair with other heating sources

If you're keen to fully activate cosy bedroom mode, why not pair your bedroom radiator ideas with log burner ideas too. Perfect for home renovations where you've restored a fireplace, or even for including in a barn conversion, there's nothing says cosy more than a roaring fire.

Just be sure to take the right ventilation measures into account to avoid the room overheating, and even if you don't have a working chimney, you could opt for a bioethanol firepleace or stove instead which doesn't require one. I tested the Arada bioethanol stove, and while it's currently located in my living room, I would happily move it to a bedroom if needed.

3. Choose low level rads in loft conversions

"When it comes to designing a bedroom, whatever the size, heating is one of those things that’s easy to overlook, but it can make a big difference to both the look and feel of the space," says Nick Duggan, managing director of The Radiator Centre.

This can be trickier in loft conversion bedrooms, where sloping ceilings can result in low level windows. Or perhaps you have a Velux loft conversion, which means the option to install radiators below windows is more limited.

In this instance, choose a lower height long column style radiator. But, make sure you get the size right too, says Nancy Emery. "Always calculate BTUs based on room size, insulation and window type to ensure the radiator warms efficiently without wasting energy," she advises.

Shop column radiators

4. Select a multi-purpose mirror radiator

Whether you're simply after a dreamy master bedroom idea or need every single item in the room to work hard, mirrored bedroom radiator ideas are a great solution.

Usually vertical in design, they can keep you warm while getting ready, but also make sure you and your bedroom are both dressed impeccably and ready to face the day.

Dual-purpose radiators are a smart choice for bedrooms," confirms Nick Duggan. "They add both style and practicality without sacrificing on space. Mirrored radiators double as full-length mirrors, while also providing effective heating."

They can also be a sensible option in smaller bedroom ideas, adds Nancy Emery who tells us, "mirrored models can add style subtly, reflecting light and creating the illusion of more space."

This White Vertical Mirrored Radiator from Amazon combines classic radiator design with a mirrored central panel if you want to signpost your heating, but still double up on functionality.

5. Consider your room layout when positioning radiators

If you're opting for the popular choice of positioning a radiator beneath a window, once you've checked the ideal radiator height from the floor, also remember to take into account your planned bedroom layout.

Although you need to ensure it's in the right place to radiate heat throughout a room, think about when you might need to be in closer proximity to the bedroom radiator for an extra boost of heat.

In this child's bedroom idea for example, the room has been set up so that a chair is placed next to the radiator, turning it into the perfect cosy spot for bedtime stories or nighttime feeds.

6. Pick radiator colours to complement your decor

Selected a bright and breezy wallpaper for decorating your bedroom walls? Instead of playing safe with a white radiator, pick out a bolder colour from the design instead and turn it into a eye-catching statement instead.

This Emmeline radiator from The Radiator Centre comes in a variety of colours and sizes to suite all kinds of bedrooms and is a classic style that will never date. If on the other hand you like your current radiator and want to update it to a more vibrant shade, follow our expert advice on painting a radiator to ensure a flawless finish.

7. Disguise with a radiator cover

Radiators of course aren't for everyone, and sometimes having a functional product out of sight is how you choose to approach your interior design. Or, perhaps you've renovated a home and while the radiator is in full working order, it's just not in keeping with the rest of your decor.

In cases like this, radiator cover ideas can be a great fix to a functional appearance. Choose the right one and you could benefit from adding radiator shelf ideas as well, giving you the chance to display treasured objects or photos in your bedroom.

8. Use a heat pump? Modern heat pump radiators can be mounted at high level

If you're installing a heat pump as part of your self build plans, choosing bedroom radiator ideas that will work with this form of heating source is essential.

The good news is there are a wide range of options to choose from now, and some of them, are perfect if your taste leans towards contemporary house design.

"With the rise of consumers using heat pumps, we are now also seeing many more models coming through which are compatible with these low temperature systems," confirms Nick Duggan.

"To truly maximise the efficiency of a heat pump system, it’s vital that consumers choose the right complementary technology. Fan convectors are a good choice as they are specifically designed to work at between 30°C and 45°C, whilst still delivering the required heat output," he explains. "Some models can also deliver cooling in summer, making them ideal for keeping your bedroom comfortable all year round," and preventing you needing to consider installing air conditioning as well.

9. Frame it using wall panelling

If your bedroom size leans towards larger dimensions, don't be afraid to include your bedroom radiator ideas in the mix when choosing how your walls will look.

"In larger bedrooms, don’t be afraid to let the radiator become part of the design story," advises Nick Duggan. "With so many beautiful styles available, from bold, sculptural shapes to soft, architectural finishes, it’s possible to turn a practical feature into something that really elevates the room."

Pair a classic column radiator with wall panelling ideas and a stunning wallpaper to match, for bedroom that's as elegant as it is practical.

10. Pick a vertical design when you need to save space

If on the other hand you're looking for bedroom radiator ideas to suit your smaller guest bedroom, switching the orientation of your radiator from horizontal to vertical will help.

"Slim vertical designs are ideal for tight spaces," says Nancy Drench, leaving the lower wall levels free for furniture such as beds and chest of drawers. Not sure how much space you need in a guest bedroom? Check out our guide to getting room sizes right.

11. Could a bathroom radiator provide extra display areas?

Sometimes, when choosing bedroom radiator ideas, or any design ideas that matter, it can pay to think outside the box. While it's easy to pigeon hole products into rooms because that's how they are packaged up, who says you can't switch things up?

As long as you check with a heating expert that your chosen model will provide sufficient heat, I think bathroom radiators can make a good choice for bedrooms too.

Why? If you like the thought of warm clothes in the morning, or toasty pyjamas at night then a towel radiator designed for hanging towels could be the perfect solution you didn't even know you needed.

Of course, with heating bills on the rise, while choosing a bedroom radiator idea that looks good is important, it's also important to consider the efficiency levels too, finishes Nick Duggan.

"Sustainability is also a huge factor for everyone and in the heating sector there are some great energy-efficient designs that are now on the market, with more being introduced all the time," he explains.

"One of the recent models we introduced features a remarkable water saving of approximately 80% less than a traditional tubular multi-column radiator," he says. "When you have less water in the system it means less energy is required to heat it up, saving on cost as well as energy consumption."

If your idea of a warm and welcoming reception room includes living room radiator ideas, you're in the right place. Whether it's a classic column radiator or something more modern, we've curated a selection designed to suit homes of all shapes and sizes.

While once limited in terms of their aesthetics, from radiators for bay windows through to living room radiator ideas that double up as a piece of art, the choice and selection now available for your living room design knows no bounds.

Throw into the mix some expert advice on how to choose the right radiators to warm the space efficiently, and we're confident you'll soon be basking in the heat of your successful selection.

1. Choose a radiator in a tonal shade to match your walls

Unlike underfloor heating which is hidden out of sight, if your choice of heating emitters is radiators, you need to pay attention to not just how they work, but also how they look.

"The first thing I always advise is to work out the heat output your room actually needs and you can do this using a simple heat calculator," advises Nick Duggan, director of The Radiator Centre. "It takes into account the size, insulation and layout of your living room so you know exactly how powerful your radiator (or radiators) should be."

But, then it's a matter of style he confirms, saying how, "when it comes to living rooms, radiators can play just as much of a role in the design as your furniture or living room lighting ideas."

If you're a fan of jumping on paint trends when decorating, then don't forget to apply this to your choice of radiators too. The Milano Aruba Radiator shown here, is a darker shade of blue, complimenting the lighter blue paint used on the walls. Further proof that while some experts say blue is tricky to use in interiors as it's a cold colour, when used well it's far from chilly.

2. Use your radiators as art

If minimalist living room ideas or more contemporary spaces are your preference, a radiator would once have been seen as the boring sidekick, nestled away in the corner of a room with perhaps a chair or sofa pulled in front to hide it.

However, in today's world, the best radiators are no longer an unwanted exhibit, and it's up to you to decide how prominent a feature you make of them.

"The big question is: do you want your radiators to blend in or stand out?" says Nick Duggan. "A bold colour or unusual shape can turn them into a feature, while neutral tones and slimline models allow them to quietly do their job in the background."

3. Position radiators between shelving

Every living room needs good living room storage ideas, so why not use your bespoke shelving to frame a boldly coloured radiator that matches the items on display on your shelving?

Extending the built in shelving and storage at floor level, also means there's the right amount of space to add some cushions and padding, creating the perfect spot for listening to music or reading a book on cold winter nights. Snuggled up to the radiator, you may never want to move.

Just make sure you know the size and dimensions of the radiator you need before committing to your shelving design, says Nancy Emery, heating expert from Tap Warehouse.

"Living rooms typically need higher output due to their size and openness, so choose models with a high enough heat output to keep the entire room comfortable."

4. Soften modern design with round edged radiators

If you prefer to colour drench your living room in lighter shades, and use finishes common with contemporary homes, such as microcement or polished concrete, it can quickly become too sterile and harsh without something to soften it.

Soft furnishings and furniture with plenty of texture, will help, but with radiators bringing the actual warmth, why not use these as a means of softening the edges too.

This curved, dusky pink radiator from The Radiator Centre helps to break up the wall and its curved design matches that of the occasional tables.

And, if along with your modern design you're looking for radiators that work with air source heat pumps too, many retailers offer them as part of their range. Check out these heat pump compatible radiators from B&Q as a starting point for your living room radiator ideas.

5. Upgrade an older model with a sleek radiator cover

If your current radiator provides sufficient heat and is in perfectly good working order, you may be loathe to spend money on new living room radiator ideas, preferring to splash out on something like new living room wall lighting ideas instead.

This of course makes total sense, but may still leave you feeling your final look is spoilt by the radiator that's in situ. If this sounds familiar, why not go halfway and purchase a new radiator cover instead?

Pick a radiator cover idea that matches your new living room colour scheme, and you can wave goodbye to bland and hello to a more sophisticated style.

6. Placement is key in multi-purpose living rooms

While many living rooms are only used during the evenings or weekends, if your living room doubles up as a small home office space, it could be worth thinking about where you position your radiators.

Working from home during the winter months can sometimes feel chilly, so in this multi-purpose living room, a small radiator is positioned opposite the desk. Although the heat will spread throughout the room, having a source of heat directed at you while you work can be beneficial.

Alternatively, if you have already completed your home renovation and don't want to extend your heating system, why not consider a wall mounted or portable electric radiator instead, such as this Ecoso Vitrum Smart Electric Glass Panel Heater from Best Heating.

7. Use curved radiators with bay windows

One of the most efficient places to install radiators is below windows, says Nancy Emery, who tells us, "placement under windows helps to counter draughts and optimises circulation."

However, when you have a large curved bay window to tackle as part of your home renovations plans, it may feel like you're trying to fit a square peg in a round hole when looking at different types of radiators.

The good news is, curved versions, such as the Nordic Oslo Curved Bay Window Radiator from Trade Radiators are readily available, which means you can take advantage of the space below the window as recommended.

8. Make the best material choice for your living room use

When choosing radiators for your new living room extension for example, you need to think about how often the room will be used before selecting your living room radiator ideas.

"Different radiator types and materials perform in different ways," explains Nick Duggan. "For example, aluminium radiators heat up and cool down quickly, making them very responsive and efficient for living spaces that aren’t used all the time.

"Thinking about how you use your living room can help guide the most efficient choice for your home," he advises, "and with today’s home insulation methods, you’ve also got more freedom."

Rather than relying on the space below the window, "a vertical radiator can instead be a brilliant space-saver on a narrow wall," he suggests.

9. Pair bold colours with traditional design

Despite modern building and insulation methods, if you're renovating a Victorian house however, you may still benefit or even need the longer lasting heat provided by more traditional cast iron radiators.

“Start with performance,"recommends Nancy Emery. "Calculate BTU output based on room size, glazing, and insulation. It’s really important as oversizing wastes energy, while getting one too small won’t do the job efficiently."

With regards to choosing the style, "column radiators add character and warmth to period-style homes," agrees Nick Duggan, but that doesn't mean opting for a plain finish. "They can even be colour-matched to your décor," he confirms, meaning bold and bright is totally within reach.

10. Place a radiator below a cosy window seat

Window-seats are a long time favourite of mine and I love this concept which is why I've included as a living room radiator idea. Who wouldn't want to be snuggled up on here with a toasty derriere, a copy of Homebuilding & Renovating magazine and a mug of hot coffee.

Wall mounting your radiator in this instance keeps the look streamlined, and to help ensure this cosy seating spot doesn't get too hot, or too cold, make sure you've fitted thermostatic radiator valves to give you maximum control.

Or, if you are opting for a floor mounted radiator, make sure you know the ideal height to install it.

Of course, once you have your living room radiator ideas in situ, keeping them well maintained is the best way to ensure you aren't looking to replace them any time soon. For maximum energy efficiency and heat, make sure you you know how and when to bleed radiators, and if you do encounter problems, check out our guide to the reasons why your radiator may not be heating up properly.

A radiator shelf is a simple way to give an unloved panel purpose, add a spot for styling, and make a space feel more finished, all without much effort or expense.

Whether it’s a slim hallway ledge for post and keys, a painted timber top that complements wall panelling, or a bespoke addition beneath a bay window, a radiator shelf brings charm and function in equal measure.

And it’s not all about looks, either. The right shelf can help direct heat back into a room, protect your walls, and even disguise unsightly types of radiators if a full cover feels too bulky. From simple DIY ideas to custom designs, we’ve rounded up some of the best radiator shelf ideas to get you started.

1. Introduce a minimalist floating shelf to suit any design scheme

“Practically, a radiator shelf is a brilliant trick for reclaiming what is often dead space,” says Erdem Yenice, founder of Quanta Home. "A simple floating shelf or a slim metal design works wonders in a more minimalist space. It grounds the radiator, making it part of the decor rather than just a utility."

If your radiators are sleek and pared back, your shelf can follow suit. But that doesn’t mean it has to feel cold or clinical. In the setup above, a flush-mounted panel radiator is paired with a floating oak shelf to keep the lines clean while adding a touch of warmth and natural texture to the room.

“The most important thing to consider, of course, is the heat,” adds Erdem Yenice. Notice that the shelf isn’t fixed directly to the radiator but mounted higher up the wall. It's a subtle design choice that also allows for better airflow. Homeowners should always ensure there is enough of a gap for air to circulate properly. Erdem suggests aiming for at least 5cm of clearance above the radiator to prevent heat from becoming trapped.

Expert tip: “Keeping the length of the shelf aligned to the valves rather than the radiator helps with the visual balance,” says Garth Bretherton, expert at JIG UK.

2. Pair a painted radiator with a slimline shelf

A radiator doesn’t have to hide in the background. Painting it in a bold colour – like this electric blue column design – can turn a practical fixture into a real talking point. Here, it’s paired with a slim timber shelf with hairpin legs, adding balance without taking away from the radiator’s statement moment.

“From a design perspective, a radiator shelf transforms a purely practical fixture into a considered part of the room," says Nick Duggan, managing director at The Radiator Centre. "It creates a smart visual line, breaks up blank wall space and offers a handy surface for styling with home accessories.”

For extra impact, try painting the radiator and shelf in contrasting tones. A rich colour below and a paler finish above will naturally draw the eye and help the whole setup feel more considered.

Just be sure to choose the best radiator paint for the job, it needs to be heat-resistant and suitable for metal, especially on older cast-iron styles. We like Rust-Oleum Heat Resistant Radiator Paint from at Amazon because it's available in a wide range of shades to suit all kinds of interiors.

3. Add a shelf to a towel radiator for a spa setup

In bathrooms, radiator shelves offer a useful place to stash toiletries and keep towels toasty. Here, a chunky oak shelf is built into the frame of a matt black towel radiator, creating a sleek and structured look that wouldn’t be out of place in a boutique hotel.

While this shelf is on the smaller side, it’s ideal for housing everyday bathroom staples or adding a subtle decorative touch. Just be mindful of material choice in a space like this. “Natural materials such as wood can warp at high temperatures and metal parts can get very hot,” warns Dimitri Pappas, MD at My Furniture. When in doubt, consider opting for treated or engineered materials designed to cope with changes in temperature and humidity.

In small bathrooms, where radiators are often placed close to fixtures or walls, positioning becomes just as important as material, so make sure there’s enough breathing room around the shelf to maintain airflow and avoid a build-up of heat.

4. Opt for a radiator cover with its own built-in shelf

If you’re looking to completely disguise your radiator while adding a useful surface, a radiator cover with an integrated shelf is a fantastic option.

This Anastasia White Glass Radiator Cover from MyFurniture features a sleek slatted design that instantly elevates the look of the room, transforming the radiator into a piece of contemporary furniture in its own right.

The slimline shelf on top offers just enough space for styling sculptural objects or everyday essentials, making it a smart choice for hallways, living rooms or anywhere you want your heating to work a little harder on the style front.

5. Go minimal with a shelf-style radiator

Who says a radiator shelf has to be separate from the unit itself? This sleek horizontal design from The Radiator Centre doubles as both heat source and a ledge, ideal for hanging towels without interrupting a modern bathroom scheme.

“A simple floating shelf or a slim metal design works wonders in a more minimalist space,” explains Erdem Yenice. “The key is always to complement the home’s character.”

Expert tip: Always check the manufacturer’s guidance before placing items directly on or near the radiator surface.

6. Choose a radiator designed with a built-in shelf

Some of the smartest radiator shelf ideas are built into the design from the start. This sculptural towel rail from The Radiator Centre doubles as storage, with space between the bars that’s perfect for neatly folded towels and linens.

It’s a simple solution for small bathrooms or utility rooms, where storage is tight but style still matters. By building shelving into the radiator itself, you get both form and function in one, and there’s no need for separate towel storage or bulky furniture.

7. Transform your radiator shelf into a window seat

If your radiator sits beneath a window, why not turn that spot into something special? This clever built-in design hides the radiator beneath a raised bench seat, giving you the ultimate cosy nook and a discreet way to keep the room warm.

While it might not be a traditional radiator shelf, the concept is similar. Add cushions and throws to your window seat and you’ve got a snug, practical feature that feels completely intentional.

Just ensure there's enough ventilation underneath and behind the seat to allow heat to circulate freely and always use heat-resistant materials for any boxing-in.

8. Turn the radiator itself into a seat

When floor space is tight, it makes sense to let your hallway radiator ideas work a little harder. Rather than adding a separate shelf above the unit, why not flip the idea and turn the radiator into a bench instead?

This design turns the top of the radiator into a built-in perch, perfect for popping on shoes or dropping your bags when you get home.

It’s a practical twist on the classic radiator shelf concept and especially useful for utility room ideas or bootlity rooms where space is often at a premium.

9. Place your radiator underneath a niche

If your home has alcoves or wall niches, positioning a radiator beneath one can create a built-in look, especially when the niche includes a ledge or stone shelf. While you won’t get the same heat-deflecting benefits as a proper radiator shelf, it still acts like a mini mantel, offering space for styling without the need to mount anything directly above the radiator.

“It can completely change the feel of a room,” explains Erdem Yenice. “For rooms without a fireplace, it can even act as a modern mantelpiece – a perfect stage for creating a personal display.”

10. Use a windowsill as a ready-made radiator shelf

Windowsills naturally lend themselves to shelf-style styling, and if there’s a radiator below, even better. While not technically a radiator shelf, the ledge above serves a similar purpose, giving you space to style decorative objects while helping reflect warmth back into the room.

This is especially effective in period properties where radiators often sit directly beneath tall sash windows. Just try and keep your decorative display light and balanced, so the sill still feels usable, and choose materials that won’t be affected by long-term exposure to heat.

“A radiator shelf might seem like a small addition, but it can make a big difference, both practically and visually,” says Nick Duggan, managing director at The Radiator Centre. “On a functional level, it helps redirect heat outwards into the room, rather than letting it rise and escape, which is especially useful under windows. It also acts as a protective barrier, shielding walls, artwork and window dressings from direct heat.”

Remember, if you're planning to include a radiator shelf idea in your space, it's worth considering what the ideal radiator height is from the floor, as this can affect both heat flow and how the space functions day to day.

Oil filled radiator vs convector heater; which one will give you a quick hit of heat to warm up a space? The simple answer is that they both will, but in different ways. One will give an almost instant heat while the other will retain the heat for longer.

They don’t work like the plumbed in types of radiator you typically have in your home, but they are a handy addition for colder rooms that need a boost. But which you need isn't always an easy decision. Both have their plus and minus points, and in this guide we help you decide which you should choose when the temperature drops.

Oil filled radiator vs convector heater: Key differences

While both provide heating for the home, convector heaters and oil filled radiators work in very different ways to produce and output heat. Adele Brennan, home electricals buyer at VonHaus goes into more detail on how they work, “Oil filled radiators work by heating up a reservoir of oil inside the radiator, which then transfers the heat to the radiator’s metal fins.”

And it's the fins that output the heat as Brennan adds, “These fins then radiate the heat into the space, helping to keep rooms warm, even after being switched off.” Oil filled radiators, shares Brennan, “Usually come in a range of different sizes.”

This can refer to their physical size and the output of the radiator itself. Mini filled radiators like this VonHaus Mini Oil Filled Radiator (available from VonHaus) can output around 800W, making them ideal for smaller space such as a bedroom or home office. Larger models like this De'Longhi Dragon 4 Oil Filled Radiator from Amazon, have an output of 2000W and are suitable for space up to 60m2.

Convector heaters - as you might expect - do not use oil to produce heat as Brennan explains, “Convector heaters pull in cold air from the bottom and circulate it through the heater, creating hot air.” She adds “These heaters tend to be better known as panel heaters and are great for heating larger spaces.”

Try these portable oil filled radiators to heat up a space

Pros and cons of an oil filled radiator

Here Adele Brennan from VonHaus points out the plus and minus points of oil filled radiators to help you decide if they are for you.

+ Long-lasting heat
The oil inside stays hot long after being switched off, which helps to keep rooms warmer for longer – a huge bonus in colder temperatures. The oil also heats evenly throughout the radiator, meaning you’re getting the most from the radiator.

+ Aesthetics
A lot of oil filled radiators come in a range of different sizes and colours. Sizes can range from 5 fins right up to 17 fins, and there are even some closed fin models available too. You can now also get smart-operated radiators which link up to apps on your phone.

+ Safety features
Most oil filled radiator models come equipped with overheat protection and a tip over switch. This means that there is no concern of the radiator overheating, and if the radiator is tipped over it will switch off automatically.

- Slower to heat up
Although a lot of oil filled radiators can now heat up fairly quickly, you may still notice that you’re not feeling the heat as quickly as other heaters

- Not suitable for larger/open spaces
Although oil filled radiators can come in a range of sizes to suit different sized spaces, you may find that these models may not heat large rooms or open spaces as adequately.

- High surface temperatures
Oil filled radiators are very hot once heated, making them potentially dangerous for families with pets and small children.

Try these convectors heaters to warm up your home

Pros and cons of a convector heater

Here Adele Brennan looks at the positives and negatives of convector heaters to help you with your buying decisions.

+ Quiet
Most convector heaters are often very quiet as they’re only circulating air, making them an ideal choice for home offices or bedrooms.

+ Quick heat
Convector heaters can warm a space pretty quickly which is helpful for those looking for instant heat.

+ Lower price point
Most convector heaters tend to be cheaper in price, making them a good budget option.

- Poor air quality
Convector heaters are powered by air circulation, but don’t have air filters, which means they can circulate dust and potentially make allergies worse.

- Dry air
Convector heaters can dry out the air, which could cause issues for those with sensitive skin or breathing issues.

- Expensive to operate
Electric convector heaters can be expensive to run for long-term use – they aren’t designed to be used over long periods of time.

Which is cheaper to run: Convector heater or oil filled radiator?

As a general rule Brennan says, “Oil-filled radiators are generally more energy efficient than convector heaters because they retain the heat that is generated due to the oil staying hot, making them more cost-effective.” Check our oil filled radiator cost to run guide for more details.

But on the flip side she says, “It could be argued that convector heaters could be cheaper to run as they warm up quicker, which means you could end up using the heater for less time which would save on running costs.”

However, the running costs are dictated by the power of the appliance in kilowatts and the cost per kWh. Multiply these two together and you will get the running cost of the unit. The rate as of October 2024 is 24.50 pence per (kWh). Multiply this by the power and you get the cost per hour. For example, a 2000W (2kW) heater is 49p per hour (24.50p x 2kWh = £0.49).

Check out our central heating costs per hour guide to get a comparison of running costs between the different heating solutions.

Oil filled radiators and convector heaters are great for short bursts of heating. But they need to be complemented by a more complete form of heating. Take a look at our underfloor heating guide, most economical way to use central heating and how to choose heat pumps as alternatives to heat your home.

Radiator valves are small but mighty and knowing how to fit a radiator valve can help save money and make sure that your heating system is running efficiently. It’s a little job that can make a big difference.

But why change a radiator valve? If your radiator is not heating up properly, it could be an issue with a valve. It may be leaking, which will lower efficiency and cause water damage. It may be old and you need a new radiator valve.

Gordon Chalk and Alan Houghton, managing directors at Next Level Underfloor Heating and Screed Solutions suggest, “If your valves are over 10 years old it’s worth replacing them as part of your annual heating system maintenance.”

Here you can find out how.

Try these tools to help fit a radiator valve

7 steps to fit a new radiator valve

Here Chalk and Houghton reveal the steps you need to take to fit a new radiator valve. Make sure you have your containers, towels and tools to hand.

1. Turn off heating system

Before you start, make sure your heating system is off and the radiators are cold. This will prevent burns and any pressure issues with the system.

2. Drain the radiator

Place a container or bucket under the bleed valve to catch the water. You’ll need to turn off the radiator’s valves (both lockshield and TRV if present) to isolate it from the rest of the system. Closing the valves will (isolate) stop water coming into the radiator. Once done, start draining the radiator by turning the bleed valve with a bleed key like this Solid Brass Radiator Bleed Key from Amazon.

3. Remove the old valve

Don’t forget to place your container and towels under the valve before you start to catch any water. Using an adjustable spanner, unscrew the union nut from the old valve to the radiator. You may need to use pliers or a wrench to hold the valve body steady while you loosen the nut.

Once the water stops coming out, put a cloth in the hole to stop any drips. Now open the valve i.e. the TRV, a little way and collect any water until the pressure drops and the water stops. Now undo the nut on the bottom and remove the valve.

4. Prepare the pipework

Once the old valve is removed, clean the pipework where the new valve will be attached. Apply some PTFE tape to the pipe fitting threads and a little joining compound on the inside ready to attach to the pipework and radiator.

5. Fit the new valve

Screw the new valve onto the pipework and secure it. Make sure the valve is in the right place and all connections are tightened to prevent leaks. Now reattach the union nut to the radiator and tighten, making sure it's secure.

Check both connections and make sure they are tight. Chalk and Houghton suggest, “If you’re upgrading to TRVs remember to fit them on the flow side of the radiator. Though some newer models can be fitted on both flow and return sides." Make sure to check.

6. Refill and bleed the radiator

Now turn the both valves back on and let the radiator fill. Once the radiator is full, turn the bleed valve open, but only slightly, with your bleed key to release any air and close when water starts to come out.

7. Test the system

Finally, turn your heating system back on and check the radiator for any leaks. Check the radiator heats evenly and the new valve is working.

FAQs

Can you fit a radiator valve yourself?

A competent DIYer with the right tools should have little problem fitting a new radiator valve, especially if it is only a single valve. There are a few steps that you need to follow (which you’ll find in this guide) to make sure that all goes well.

However, fitting multiple valves is a little more involved and if you are not confident tackling the task, it would be wise to get in a professional to do the job.

How long does it take to fit a radiator valve?

Fitting a single or set of radiator valves on a single radiator that doesn’t involve draining down your heating system shouldn’t take too long. As a rough guideline set aside an hour or two to do the job.

However, if you are replacing multiple radiator valves and you do need to drain down your heating system it can easily take half a day to a day depending on how many radiators are being changed.

How much do plumbers charge to change a radiator valve?

The cost to change a radiator valve will depend on a few factors including location and type of valve. But as a general guideline Chalk says, “On average for a single valve replacement plumbers in the UK charge between £75-£150.” This will typically include a call out charge, plus materials and labour.

But as you would expect more valves will cost more as Chalk continues, “For multiple valves – say 5-10 radiators – you could be looking at £300-£600 depending on labour costs and the job complexity.” He adds, “Thermostatic Radiator Valves (TRVs) are slightly more expensive to replace than lockshield valves as they have more functionality.”

Chalk and Houghton suggest when replacing multiple valves ask your plumber if they offer a discount for bulk replacements. Many will reduce the per valve price if you’re having several done at once.

Do you need to drain the heating system to change a radiator valve?

Yes and no. If you are changing the valves on a single radiator then there is typically no need to drain your heating system. One of the benefits of this is that you won’t be removing the inhibitors present in the system.

These help protect against corrosion and stop rust flowing through the system and slow down the buildup of limescale and sludge. Which in turn helps protect the system and prolong the life of the boiler and radiators.

If you are changing multiple valves on multiple radiators or replacing radiators – typically three or more – then it is advisable to drain down the heating system.

Can a leaking radiator valve be repaired? Or should it be replaced?

Whether you should repair or replace depends on why a radiator valve is leaking. You might be able to solve the problem by simply tightening the appropriate nut on the valve. If this doesn’t work you might just need a new olive like this Flomasta Brass Compression Olive pack from B&Q. They cost very little and are easy to replace.

If a tighten or a new olive doesn’t solve the problem, invest in a replacement as they are not expensive to replace, expect to pay around £5-£20.

New radiator valves will make your heating system more efficient and cost effective, so why not give them a makeover at the same time.

2. Inject an Art Deco touch with a mirrored design

Rather than viewing a radiator cover as only a method of concealment and looking for ways to make it blend into the background, why not turn it into an eye-catching feature to be admired instead, just as if you were choosing designer radiator ideas?

This highly stylised, mirrored cover, from My Furniture, features hand-cut, bevelled mirror panels and is adjustable, making it suitable for many sizes of radiators, up to 78cm in height, 99 cm in width and 18 cm in depth.

There are other benefits to installing a mirrored or metal radiator cover too.

"In terms of being highly efficient at radiating heat into the room, metal radiator covers, often made from materials like steel or aluminium are a better choice," says Nick Duggan.

"Although they can be more expensive than other options, they are very durable and available in a range of modern and traditional designs.

"Similarly, perforated metal radiator covers combine the durability and heat-conducting properties of metal with decorative perforations or patterns that allow heat to pass through. These can be an excellent compromise between efficiency and aesthetics."

3. Get vintage vibes with a simple curtain cover

If you are keen to introduce some vintage vibes into your interior scheme or are after some rustic living room ideas, then you might like to consider an alternative to a traditional wooden or MDF radiator cover and use something that looks a little more homespun.

Here, a pretty striped curtain has been used to cover the radiator and a simple wooden shelf attached above to hold decorative or useful items. This look would be easy to recreate and is a great idea if you are on a tight budget too.

4. Paint your radiator cover to match your walls

By painting your radiator covers to match your walls they will blend in and become almost invisible. If you are working with narrow hallway ideas or within a small space, using the same shade on your walls and radiator cover will help visually increase the sense of space too.

In this stylish hallway, the lower section of the walls, door architrave and dado rail have all been painted in Cambrian Blue from Annie Sloan, as has the radiator cover, while the upper section of the walls is a crisp white.

5. Create a focal point with a radiator cover

If you love the idea of treating your new radiator cover as a focal point – perhaps because you are looking for ways to introduce a little character and personality into an otherwise bland space – then the right radiator cover could just help.

The radiator cover here, from My Furniture, has a white and gold finish which adds an instant hit of glamour and luxury without being 'over-the-top'. It would make a great first impression when used alongside your hallway ideas.

6. Bounce the light around with a mirrored finish

It is no secret that mirrors are a brilliant way of making spaces feel bigger than they really are as well as helping to bounce light around in a room that doesn't receive much in the way of natural light. Using a mirrored design of radiator cover should strongly be considered by those after small hallway ideas.

There is no reason why mirrors should be restricted to your walls though. There is a good selection of mirrored radiator covers available too which really can help to open up a room — as well as adding a little opulent style.

This model is the Etienne Standard Mirrored Radiator Cover from My Furniture.

7. Choose a model with drawers for extra storage

Whether you are after hallway storage ideas to keep your entryway clutter-free, or need somewhere to store smaller items such as remote controls in the living room, a radiator cover with drawers is a brilliant option.

The model here is the Bhawna Large Radiator Cover from Wayfair. It is made from engineered wood for a classic look and features three small drawers that would be perfect for holding items such as keys.

8. Create colour contrast with your radiator cover

You don't have to feel that your radiator should be painted in a shade to match your walls. It can actually look really stylish to select one in a colour that really stands out against the shade you have chosen for your overall background hue.

This grey design is the Chaney Extra Large Radiator Cover from Wayfair. It is finished in a stylish matt grey, giving it a distinctly modern look, while the horizontal slats would help to visually stretch a smaller room — perfect if you are after small living room ideas.

9. Add drama with a striking black cover

A black radiator cover is a great choice both for owners of period properties as well as for those living in contemporary-style homes looking for modern living room ideas.

Although people are often scared of using black in their homes, fearing it could be overwhelming (or perhaps still thinking back to the black ash trend of the late 1980s) it can look really stylish when used in smaller quantities and as an accent colour.

Here, the Cassiopeia Wall-Mounted Black Radiator Cover from Wayfair adds an elegant, understated touch.

10. Pair a radiator cover with wall paneling for country chic

Painted woodwork lends a warming, country feel to a room, whether that is through wall panelling ideas or painted furniture. In order for your radiator cover to fall in with – and even enhance – your interior design scheme, it is a good idea to choose one with a painted finish that you can emulate elsewhere in the space.

In this cosy country living room, the off-white colour scheme has been taken into account when selecting a radiator cover that ties in perfectly with the space.

FAQ

Do radiator covers block heat?

A question asked by many homeowners is 'do radiator covers block heat?' However, this will very much depend on the style of cover you choose.

"Our radiator covers are meticulously designed to optimise airflow and heat transfer without compromising on aesthetics," says Dimitri Pappas. "We estimate that the efficiency reduction with our covers is no more than 5%."

"Radiator covers can reduce heat output," adds Nick Duggan. "Firstly, they can limit the amount of infrared heat (the same heat you would experience by standing in front of an open fire). Secondly, they also restrict the amount of cooler air that can be drawn across and out from the radiator so further limiting its heat. This could all result in 30% less heat getting into your room.

"However, nowadays there are plenty of styles that not only look good but also have great heat outputs and are very affordable," reassures Nick.

If you are still keen to change your radiators rather than invest in some covers, take a look at our guide to installing a radiator to save money on labour costs.

Despite the positive news around the subject of heat pumps, there are still a large number of heat pump myths that continue to prevail. In fact, as recently as 2023, over 25% of homeowners surveyed by Good Energy believed that heat pumps were more expensive to run than gas boilers – a fact that simply isn't true.

From expense to longevity, limits on their compatibility with heating types to their suitability for older homes, we've asked the industry experts to help us unravel the claims to see if there's any truth in heat pump myths – or if it's simply all make-believe.

Are you ready? Then let's reveal what's fake and if there's any fact when it comes to heat pump myths.

Heat pump myths

1. Heat pumps only work in new homes

Not to be confused with the gas boiler ban that has been put in place to ensure that all new homes built from 2035 have a heat pump, age is not the main defining factor when asking is my home suitable for a heat pump?

"If a building can be heated with a boiler, it can be heated with a heat pump. Many people think that old homes are not suitable for heat pumps – this simply isn’t true," says Tamara Birch, senior writer for The Eco Experts.

"Heat pumps are suitable for virtually any property," confirms Hamid Salimi, national residential product manager at Daikin UK. "They’re ideal for homes of all shapes and sizes, whether new build or older. While it can be easier to plan a heat pump installation into a new build, there’s absolutely no reason why they can’t be installed in older houses or renovation projects.

"Their innovative design means they’re simple to install, with no expensive groundwork, and in most cases, no planning permission is required," he adds.

Instead, says Steve Cole, retrofit co-ordinator at the Centre for Sustainable Energy, what matters more is, "the proper sizing of the heat pump and radiators according to your home's specific heat demand." Fabric first measures such as adding insulation and reducing air leaks – more common in older homes – will always help, but don't stop you from having a heat pump.

Properties with limited outdoor space, or those living in an apartment or flat might need to explore a wall-mounted or roof-top option say the experts, but when it comes to knowing are heat pumps suitable for old homes, the answer is definitely yes.

2. Heat pumps won't work with radiators

The truth that heat pumps work well with underfloor heating has perhaps led to a common assumption that this means they don't work with radiators.

But again, this is not true. "Heat pumps and underfloor heating work well together because underfloor heating works at lower temperatures than radiators and is usually on for longer. It takes more time to heat up and cool down, both of which suit heat pumps," explains Steve Cole. "But, you absolutely don’t have to have it, and many homes with heat pumps do not have underfloor heating," he adds.

"It is true that heat pumps work well with underfloor heating systems," agrees Tamara Birch, "as the low temperature increases the efficiency of the heat pump, but you can still install a heat pump with normal radiators."

One way of compensating for the lower temperature is to increase the surface size of your radiators, or choose types of radiators specifically designed for heat pumps.

"Energy efficient radiators are designed to maximise the amount heat generated and often includes features like fins, convectors, or other elements that increase the surface area available for heat exchange in more clever, discreet ways," explains Nick Duggan, managing director of The Radiator Centre.

"These energy-efficient radiators also include an optimised heat exchanger, which uses 90% less water than is used in standard radiators, meaning less energy is needed to heat the water up," says Nick, "This also brings other advantages in that the radiators take less time to heat up and you lower your carbon footprint at the same time. For hard to heat areas many energy-efficient designs also come with a fan-assisted ‘boost’ that can generate up to three times the amount of heat that a conventional radiator would generate."

Or, if switching radiators doesn't appeal, you could opt for a high temperature heat pump instead. Bean Beanland, director for growth & external affairs for the Heat Pump Federation, offers some words of assurance regarding this option.

"In the last 18 months, a team from University College London, analysed data from 4600 boilers. They discovered that with the vast majority of them, you wouldn't need to change the radiators at all. You could simply swap the boiler out for a high temperature heat pump, and your heating would work quite happily."

This myth about heat pumps and radiators is also partly about the perception of what hot should feel like, says Bean.

"If your radiators are operating on a weather compensated heat pump system, they're always on, they just won't feel on. In fact we used to get phone calls with people saying, well, the radiators are cold or they aren't very hot. But the room would be warm," he says.

"People's perception, is that if you touch it and it’s not taking your skin off, there must be a problem. Those days are gone. We now limit hot water temperatures for safety reasons and radiators shouldn't be so hot that you can't touch them."

3. Heat pumps are more expensive than gas

This myth is one where there is perhaps some context, but only with regard to the initial costs of purchasing and installing a heat pump vs a gas boiler.

"The biggest downside of a heat pump compared to a gas boiler is the upfront cost," says Tamara Birch. "It’s undeniable that a heat pump costs more than a boiler to install. However, there are many grants available, such as the Boiler Upgrade Scheme, to help reduce the upfront costs."

And, while it may cost more to install, you will reap the rewards when it comes to the reduction in running costs.

"If specified correctly, a heat pump shouldn’t be more expensive to run than a gas boiler," confirms Hamid Salimi. "By using low energy tariffs by utility providers, the end user can also further reduce running costs. And you can utilise other technologies, such as solar panels, to further reduce costs." A fact backed up by the Energy Savings Trust who predict that if you are placing an old G rated boiler with a heat pump, you could reduce your costs by around £340 each year.

What's also important to remember in the cost equation is the improvement in efficiency of a heat pump compared to a gas boiler – a calculation known as the co-efficient of performance or CoP.

"A modern A-rated gas boiler operates at about 90% efficiency, converting 90% of the energy it consumes into heat, with 10% lost as waste," explains Hamid Salimi. "In contrast, heat pumps are significantly more efficient. Air-source heat pumps achieve around 300% efficiency. This means for every 1kWh of electricity used, they generate 3 to 4 times more heat."

Install a ground source heat pump and you could find this number increasing to 400%.

"In terms of environmental costs, heat pumps are also a far stronger investment," notes Tamara Birch. "According to The Eco Experts’ calculations, heat pumps reduce your annual carbon footprint by around 44% compared to a gas boiler."

4. Heat pumps devalue properties

In the same way that this is one of the myths about solar that simply isn't fact, heat pumps equally do not devalue your home.

"It’s actually been found that a heat pump will increase the value of your property," says Hamid Salimi. "Research carried out by the WWF has shown that a heat pump could add between 1.7% and 3.0% to the value of a home.

"Installing environmentally friendly heating and energy solutions in your property makes it more attractive to buyers and can increase its value," he expands. "According to Rightmove, a property moving from an EPC rating of F to a C could increase its value by an average of 15%, or almost £56,267 when looking at the national average asking price.

"Furthermore, homes with green improvements command a premium over local house price growth. As energy efficiency becomes increasingly important, a home’s rating is expected to play a more significant role in buying or renting decisions," says Hamid, "driven by the potential for substantial energy cost savings and enhanced resale value."

5. You can't have a heat pump if your EPC rating is poor

Another myth that has some context as while it was once partly true, it is no longer the case.

"The Boiler Upgrade Scheme used to be dependent on having an Energy Performance Certificate (EPC) without any home insulation recommendations," explains Hamid Salimi. EPCs for homes without insulation would have been lower than ones that are insulated.

"However, in May 2024, Ofgem announced it that will now accept Energy Performance Certificates (EPCs) with insulation recommendations." So what does this mean for homeowners?

"It means you don’t need to worry about adding loft or cavity wall insulation before applying, for the grant, meaning many more households will eligible," says Hamid. "But remember, in order to apply you do still need an EPC, and you need to own the property."

It’s also important to make sure your home is well insulated to get the most efficient results from your heat pump. A more insulated property will retain heat for longer periods and therefore could help reduce energy bills.

6. Heat pumps don't last very long

"A well-designed air source heat pump installation is likely to outlast a gas boiler," says Hamid Salimi. "The typical lifespan of a heat pump is between 15 and 20 years. And if it’s maintained properly, it will carry on working efficiently for even longer."

On average, a gas boiler will last 10-15 years with proper maintenance and servicing. And while the initial heat pump costs are more than a gas boiler, when it comes to replacing your heat pump for a new one, you won't be facing the same costs again – instead, it will be just the heat pump unit.

"When that heat pump comes to the end of its natural life, you'll just replace it with a new generation unit with a different refrigerant," explains Bean Beanland. "A heat pump is not four or five times the price of a boiler. It's the initial transition that adds to the expense. But of course, if you keep telling people heat pumps are five times the price, in their mind they're saying every time I have to replace it is going to cost me five times as much. That's just not true."

7. Heat pumps are still a new technology and need more testing

While there may still be fewer homes having heat pumps installed compared to gas boilers, that doesn't mean it's a new and untested technology say the experts.

"There are around 70-80,000 heat pumps being installed each year," says Bean Beanland, "and although that's less than the 1.6 million gas boilers being fitted, it doesn't mean it's a new technology or one that still needs more testing."

"Heat pump technology is decades old", adds Steve Cole. "There are about 20 million heat pumps operating across Europe, demonstrating their reliability and efficiency."

"What's important," says Bean Beanland, "is that we look at bringing production of the heat pump units to the UK so that we can take ownership of all stages of process, from manufacture through to install and maintenance."

8. The National Grid won't cope if we all switch to heat pumps and need more electricity

While claims are sometimes made that if everyone switched to heat pumps we would overload the National Grid, the experts dismiss this as another scaremongering claim. Steve Cole points out how this is not a transition that will happen overnight and is therefore completely unfounded.

"If we were to convert every house tonight and wake up tomorrow morning then the grid clearly wouldn't cope," agrees Bean Beanland, "and while there may well be pinch points, I think that the investment programme and the level of effort that is being made by those responsible for the grid, is enormous.

"I think by and large, we will keep pace," says Bean. "The key is to keep the investment going. It was only as of April 2023 when the networks were actually allowed to invest ahead of need. Prior to that, they weren't allowed to spend the money ahead of need. So they had to wait until somebody requested more and then they would invest – but you'd have wait six months.

"Of course," says Bean, "if you're replacing a boiler, that's no good. You can't wait six months. So, this has changed. There's also some work being done which is specifically aimed at how we cope with older systems. Hot spots are being identified, the network and connections are being analysed and then homeowners are being given a certificate of readiness to say they are ready for a heat pump.

"They may get the certificate long before they’ve thought about switching," explains Bean, "but they might do in a couple of years and will be confident that they can."

9. Heat pumps are loud

Are air source heat pumps noisy is one of the most common questions asked and a myth that continues to appear on a regular basis. But why do people think they are?

"This belief can be traced back to when heat pumps were first made available to UK consumers," says Tamara Birch. "At the time, they were quite noisy, but that’s not the case today.

"In fact," says Tamara, "the legal limit for an air source heat pump unit is 42 decibels, which means that at most, they make about as much noise as a fridge or gas boiler."

When asked are heat pumps noisy, "modern heat pumps are relatively quiet," confirms Steve Cole. "They typically produce 40 to 60 decibels of sound, equivalent to a quiet office. Noise levels depend on factors like the heat pump's make, size, installation method, and how hard it's working. Strict regulations govern noise levels, and installers conduct noise assessments to ensure compliance."

10. They won't work in low outdoor temperatures

The last and final entry for the fiction category in our heat pump myths debunked, is the suggestion that heat pumps won't work as well if the outdoor temperature is too low.

It's another myth with no validity say the experts. Both air source heat pumps and ground source heat pumps are not affected by outdoor air temperature and are in fact designed to be able to work in cold conditions.

"Air source heat pumps are designed to work in temperatures as low as -25°C," explains Steve Cole. "They're common in many European countries with much colder climates than the UK. Even when temperatures drop below zero, heat pumps remain twice as efficient as gas boilers or direct electric heating. By extracting heat from the air, they can produce up to three units of warmth for every unit of energy consumed. This remarkable performance, coupled with their ability to function effectively in diverse climates, makes heat pumps not just an alternative to gas boilers, but a very good option for energy-efficient home heating."

And from a practical point of view, even though the pipes for a ground source heat pump are installed outside, the ground temperature rarely changes, making air temperature drops insignificant. This, coupled with the fact ground source heat pump units are located inside the home means they are fully protected against the elements.

Learning how to remove a radiator isn’t as difficult as you might think. But, you will need the right tools and some essential know-how which you will find in this guide. Get your hands on both and you could be saving yourself some serious money.

If you’re removing a radiator to replace with a new one, then you’ll need to know how to recycle them responsibly. If you are looking to remove to paint behind a radiator then you won’t need to worry about getting rid of them. Whatever you are choosing to do, you’ll find expert advice on how to remove and recycle in this guide.  

How to remove a radiator from a wall

Before removing a radiator from a wall there are a few tools that you'll need to complete the job. These are an adjustable spanner and a pair of water pump pliers to switch off/undo valves, a radiator bleed key to release water in the radiator, a bucket or container to catch water, plastic sheets to protect the floor and towels to mop up any stray water. 

Here Michael Wood, Head of Network Delivery at Rightio reveals a quick outline of the steps you need to remove a radiator.

1. Turn off the heating system and let the radiators cool.

2. Isolate a radiator by turning off the valves on both sides. 

3. Drain the radiators by opening the bleed valve and catching the water in a container.

4. Disconnect the radiators from the valves and carefully remove them from the wall brackets.

If you want to remove more than one radiator, Wood explains the difference. “The process for removing multiple radiators is essentially the same as removing a single unit but it should be done sequentially.” 

What does this mean? It means that you should remove the radiator nearest the radiator you just removed and so on, going in the same direction, i.e. to the left.

Once you have removed the radiators, you will need a space to store them before you get rid of them. Make sure they are completely empty before moving, otherwise you may drop dirty, rusty water onto carpets and flooring. To make sure no water leaks out, stuff a rag into each of the valves while carrying outside.

“If unsure about any part of the process, it’s often best to consult with or hire qualified plumbers or heating engineers” suggests Wood.

How much does a pro charge to remove and dispose of a radiator?

If you're not confident removing a radiator yourself, or simply don’t have the time to do the job you can call in a professional to tackle the task. But how much can you expect to pay?

“The cost for a professional to remove and dispose of a radiator can vary based on location, the size of the radiator, and any complications that may arise”, points out Wood. “On average, you might expect to pay on average £139 per hour plus VAT, but it may vary depending upon the area and if any parts are required. Disposal can incur additional charges, especially if the radiator is large or made of heavy materials like cast iron.”

Mike Watkins of Home Care Heating provides an all inclusive price of £80 plus VAT to remove and dispose of a radiator. However, “If there are any complications, such as difficult access or the need for additional pipework modifications, the price might be slightly higher. For multiple radiators, we might offer a package deal”.

FAQs

How do you cap off a radiator? 

What does cap off a radiator mean? It's what can happen once a radiator has been removed. Why? “It will stop water from entering the space where the radiator was." explains Watkins. “This allows you to safely leave the pipes in place.”

But how do you cap off a radiator? This is typically done using either push-fit stop ends or compression fittings, depending on your system.” shares Wood. “Ensure the caps are secure to prevent any leaks. 

How do you dispose of old radiators? 

If you are looking to get rid of your old radiators you can do this yourself. “Most local recycling centres accept metal items, including radiators. Check with your local council for specific guidelines and opening hours.” shares Watkins.

But some recycling centres will not accept certain types of radiators, typically older radiators. If this is the case with your local recycling centre Watkins suggests you take elsewhere, “Scrap metal dealers often take old radiators and might even offer you a small payment for the metal.”

If you don’t want to, or can’t dispose of your old radiators, most trades offer it as part of the removal service. “We include disposal, ensuring that the radiators are recycled responsibly.” shares Watkins. “Just make sure the radiators are fully drained of any water before disposal to avoid any environmental issues or mess.”

What are BTUs? is a question you should be asking yourself when you are on the lookout for a new radiator or heated towel rail. They are one of the factors that will tell what sort of heat you can expect from a unit.

Not all radiators and heated towel rails are built the same. So when installing a radiator, even similar sized radiators can have different BTU ratings. When choosing a new radiator or similar, checking the BTU will help you choose the most efficient and effective radiator for the space you are looking to heat

Here we define BTUs, what they mean, why they are important to know and answer other common questions 

What are BTUs?

BTU is an acronym for British Thermal Unit. So what does that mean? It is a measurement that is commonly used to measure heat output from different devices including radiators.

It helps determine how much heat a radiator will emit, helping decide if it's the right choice for the room you are looking to heat. It's worth noting that it's also used as a measurement for air conditioning units where it measures how many units of heat can be removed by an air conditioner. 

Why do I need to know about BTUs?

You could argue that knowing the BTU of a radiator is pointless, just leave it to the professionals, they know what they’re doing. But, if you’re a keen and competent DIYer, you will want to know when replacing a radiator. It will help you determine the output of the radiator and whether or not it is the ideal choice for a room. 

To determine what BTU you need for a room use an online calculator like this BTU calculator from Toolstation. This lets you choose the type of room, add dimensions and additional information. Note, when you get a BTU figure, e.g 5000, look for a radiator with a slighter higher BTU e.g 5500, to make sure you are going to get the output you need. 

What factors affect BTU output?

There are a range of factors that affect the output of a device, reveals Mark McShane, Plumbing, Heating, Electrical & Renewables Expert at Boiler Cover UK. “The BTU rating (i.e. output) of the device, the type of fuel the device uses (and its efficiency) and the size and shape of the device (i.e. floor or wall standing)" 

But its not just the device that determines the output continues McShane, "Exterior factors such as the ambient temperature, and the insulation quality of the room in question all have an effect on the BTU output that is required in order to adequately heat or cool a room.” 

Does a higher BTU mean more heat?

The simple answer is Yes as McShane explains, “A higher rating means a larger capacity of heat. Devices with a higher rating can produce more heat. As such those with high BTUs can supply a greater amount of heat and can also be expected to heat, and or cool a larger space more efficiently than a lower BTU rated unit.”

But beware, you want a BTU rating that matches the room, “It is important to make sure that the unit you are using is one with a BTU rating that’s suitable for a space that is not too large or not too small.” Why?, “You shouldn’t go smaller and save on space costs - the heating won’t hit the sweet spot - and you shouldn’t set up a larger unit in a smaller space as the energy usage will be unnecessarily inflated.”

What is a good BTU for radiators?

There isn’t a simple answer to this question as different factors determine the BTU rating as McShane reveals, “The optimal BTU for a radiator depends on the size of the room in need of heating. As a rough guide, the volume of your room in cubic feet can be multiplied by a factor (which relates to the quality of insulation and the local climate) to give you the number of BTUs per hour required. This should be assessed by a professional.”

But, as an example a 3m x 4m living room with a single average sized window and a single outside wall will need a BTU of 4200-4500. A similar sized kitchen with similar elements would need a BTU of 3700-4000. 

What happens if BTU is too high?

If you invest in a radiator with a BTU a lot higher than needed it can lead to issues – and cost more, as McShane explains, “If the BTU rating is too high for the space, it can cause inefficiencies like rapid cycling (when a unit turns on and off too frequently). This runs up your energy costs, can make for hot and cold spots in your rooms, and reduce the life of your system. In the long run, it endures far too many temperature changes for its intended operation.” 

His final words are simple but effective, take note, “The BTU capacity should be appropriate for the size of your room.” 

To help ensure your radiators are running efficiently and effectively you need to perform a little maintenance. Our how to balance radiators and how to bleed a radiator guides will give you invaluable information to help keep your home warm.  

There will come a time when you need to say goodbye to your old radiators. The older they are, the less efficient they become, so installing new radiators will benefit the environment and help lower your energy bills. While the practical benefits are a real bonus, it's a good time to upgrade to those smart new designer radiators that you’ve been coveting.

Whatever the reason for the upgrade, you want to choose the best radiators for your needs. You’ll need to think about what type you want, but just as importantly, you need to make sure that you get the right size to ensure they pump out enough heat. Here, you’ll find all the info you need to help you make the right choice.

Making the right choice when installing a radiator

Size, shape, style, colour, and design are key aesthetic considerations when choosing the type of radiator you want. However, you can’t forget the practicalities, such as heat output and budget.

Heat output

Patrick Garner, Gas Safe Engineer at Heatable, says, “It’s not about matching the radiator you’re taking off the wall, it’s about whether the new one delivers enough heat for the room.” He adds, “That comes down to room size, insulation levels, and the temperature your heating system actually runs at.”

Your heating system helps decide what radiator you’ll need, explains Garner, “If your boiler is set to run cooler for efficiency – as most modern systems are – you’ll usually need a radiator with a higher output than the one you’re replacing.”

Common upgrades

If you're replacing your radiators like-for-like, then you won't have too many decisions to make. However, if you're swapping in a new type or style (check out our Hallway radiator ideas), Garner recommends the following: “You’ll also want to check pipe centres, brackets and the wall type, because switching styles can mean minor pipework tweaks or stronger fixings for heavier models.”

If your home currently has the popular white flat panel radiators, you may want to replace a single panel radiator with a double panel for more warmth. Garner points out the benefits, “It’s a very common upgrade. Single panels look neat, but don’t give out much heat. Double panels with convector fins offer a big jump in output without taking up extra wall space.”

As an alternative, column radiators are a popular choice, adds Garner, “Column radiators are stylish and give a nice, radiant warmth, but they’re bulkier, heavier and take a little longer to respond.”

Choosing the right size

If you are looking for a completely new radiator design to install in your home, you will first need to determine what size radiator you need. Typically, you will replace your old radiators with a similar size. This is because all the pipework is already in place, and changing size will mean potentially expensive alterations to your piping system.

But it doesn’t need to be the same size as Garner shares, “You can go longer and lower under a window, or taller and slimmer to fit a tight space.” He adds, “The physical dimensions don’t matter as much as the heat output, which is measured in kilowatts. As long as the new radiator matches the required output for the room, the shape can change.”

Style and colours

When you’ve decided what size radiator you need, you can start getting creative and think about the shape, style and colour. There’s plenty of styles and colours to choose from – apart from white – with contemporary finishes like black and anthracite being popular. It's worth noting that you can also paint a radiator to match any colour scheme you have.

Traditional column radiators like this Acova Volcanic 2 Column Radiator from B&Q give older homes a more cohesive look and feel. When it comes to shape, it's often vertical as opposed to horizontal, but if you want to get more left field, you could splash out on something like this Reina Dimaro Designer Vertical Radiator from AQVA Bathrooms.

Calculating BTUs

When installing a new radiator, it is common to replace it with a similar-sized radiator. But you need to check if the new radiator is going to give you enough heat. Garner explains how radiators are rated, “Radiators are rated by heat output, shown in kilowatts in the UK. That figure tells you how much heat they can put into a room per hour.”

However, some retailers (like B&Q) still list BTUs. Garner explains further, “Some retailers still list BTUs, which are just an older unit – one kilowatt is about 3,412 BTUs – but watts and kilowatts are the standard measure here.”

Typically, the higher the BTU, the quicker a radiator will heat a room. But it's not that straightforward, you need a BTU rating that suits the room it's going in. To quickly work out the needed BTU in a room, use B&Q's Radiator BTU calculator. Once you get a BTU rating, check the specs of the radiator you want to purchase to make sure it matches your needs.

To convert, use this BTU to kW calculator from RS. Garner adds a note of caution, “The key thing to remember is that those figures depend on the water temperature.” He adds, “Catalogue ratings are often based on hotter systems than most homes actually run, so the real output may be lower. That’s why it’s important to size radiators based on your actual boiler settings.”

As an example for a small bedroom (3m x 3m), you will need a radiator with an output of approximately 1kW or 3000 BTUs.

Choosing a radiator's position

Existing pipework typically determines where a radiator might be positioned and is an easy way to install a radiator. However, this position might not be ideal. If this is the case, repositioning the radiator might be necessary.

Garner shares, “The main principle is: put the radiator where the heat loss is greatest, usually on an external wall.” He adds, “Traditionally, it’s under the window, because older windows were draughty and the radiator helped warm that cold air straight away. But with modern double glazing, it’s less critical, but it still works well because it sends warm air up over the coldest surface in the room.”

Garner says, “Just avoid hiding it behind furniture or thick curtains; otherwise, you’re heating the sofa instead of the room. And if you’re using thermostatic valves, make sure they’re in free air so they don’t cut off too soon.”An open wall, where no furniture will be placed and won’t cause an obstruction, is ideal. If you have a lack of wall space in a room, a vertical radiator may solve the problem.

FAQs

How much does it cost to install a radiator? 

The cost to install a radiator can vary greatly depending on the cost of the radiator(s), how many are being installed, whether you are doing it yourself and if any additional pipework, valves and TRVs are needed.

A basic white 600mm x 400m single panel radiator like the Flomasta White Single Panel Radiator from B&Q costs around £30. But a larger 1000mm x 600mm double panel version of the same radiator will cost around £75. The popular traditional radiator like this Acova White 3 Column Radiator, again from B&Q, will set you back nearly £400.

Pipework prices will vary depending on whether you are using plastic or copper pipe, with copper pipe being around three times the price. Standard valves are relatively cheap with a TRV (Thermostatic Radiator Valve) like this GoodHome Thermostatic radiator valve head from B&Q costing around £10. Check out our How a TRV works guide to find out what they do and why you need them.

A competent DIYer with previous experience should have no problem installing one or two radiators, but if you are not confident in tackling the job yourself you can expect to pay around £200 to fit a new double panel radiator. If you need more radiators fitting expect to pay £250-£500 for a day’s work. This will typically be three radiators plus draining and refilling the system.

Can I change a radiator without draining the system? 

If you are only changing a single radiator then you typically don’t need to drain down the system. Radiators typically have a lockshield valve and a TRV on each side of the radiator. To isolate the radiators switch off both valves, before undoing the nuts on the side of the radiator.

You will need containers and towels when draining the water out of the radiator before placing it out of the way. Get your new radiator and fix into place, reattach the lockshield valve and a TRV and open both to fill the radiator. Finally, you need to bleed a radiator to get rid of any trapped air and repressurise the heating system.

Ideally you don’t want to drain down the system unless necessary as it will contain rust inhibitors and cleaner that help keep the system running efficiently. These will need to be replaced at extra cost. But, if replacing more than two radiators you will need to drain down the system

If you are changing the heating system in your home as well as giving your radiators a refresh, be sure to check out all our content on types of boiler, oil boiler alternatives as well as gas boiler alternatives.

Knowing how to fit thermostatic radiator valves (TRV) isn’t as difficult as you might think. But there are some definitive steps you need to follow to make sure you’re not calling out a plumber to mop up your mistakes.

The physical changing of a TRV won’t differ from heating system to heating system, but what type of boiler and how many TRVs you want to change will make a difference on how the job is approached. If you’re only replacing a single TRV it's a job that any competent DIYer can take on with the right tools. If looking to replace more it's not so simple.

Here we explain how to replace an old TRV, why it's mandatory to have an TRV and what you should expect to pay a pro to do the job. 

How to fit thermostatic radiator valves: A quick four step guide

Before you start you will need to make sure that you have a bucket/container, towels, an adjustable spanner and a set of pliers like these Knipex Alligator Water Pump Pliers or mole grips like these STANLEY Fatmax Locking Mole Grips, both from Amazon. It's also good to know how a TRV works before you begin. 

1. Drain system 

Before you change a TRV you will need to make sure that there isn’t an active water supply flowing through the heating system pipes as independent contractor Malcolm Chessell of Project Plumbing & Gas explains, “To change a TRV you will first need to drain down the system. If you have a combi boiler you will need to turn the boiler off at the wall. Drain down the system from the drain off point at the bottom of a radiator or under the boiler.”

If you have a conventional boiler installed – rather than a combi boiler – you will need to take a different approach Chessel continues, “If you have a conventional boiler, you will need to shut off the water feed to the fill and expansion tank normally found in the loft.”  

He also suggests it is a good time to take further action, “It’s always a good idea to clean out the F&E (fill and expansion) tank when draining down the system to stop any contamination that may be in the tank finding its way into the heating system.”

2. Remove TRV 

Once the heating system has been drained you can start the process of replacing the TRV. Place towels and have a container ready just in case there’s any water left in the system. 

Chessel explains what you need and how to tackle the job, “Once the system is drained down, get a pair of grips and an adjustable spanner. Holding the old TRV undo the nuts on both sides. Remove the old TRV, remove the old olives and nuts, you may need an olive splitter for this.” 

3. Install new TRV 

Now get your new TRV and install as Chessell explains, “Put the new nuts and olives on the pipes on both sides and attach the new TRV. Now get the grips and adjustable spanner and tighten the nuts”, But take care as Chessell warns, “Be careful not to over tighten.” If needed you can tighten a little more later.  

4. Refill system 

Once the new TRV has been installed you need to “Refill the system to the correct pressure if you have a combi boiler” explains Chessell. This will differ from boiler to boiler, so make sure to check manufacturers guidelines if you haven’t done this before. Chessel continues, “ Make sure to bleed all the radiators to finish”. 

How to fit thermostatic radiator valve FAQs

Ever wondered how does a TRV work? If you’ve got radiators you almost certainly have thermostatic radiator valves installed in your home. But what do they do? What makes them different from a standard manual radiator valve?

One of the key benefits of a Thermostatic Radiator Valve is that it is one of the cheapest ways to heat a room. Why? Because it automatically controls the flow of hot water to a radiator. This means you can choose which room needs the most heat and which needs the least, helping you save on your heating bill. Here you can find out what's inside a TRV and how to use them effectively.  

How does a TRV work? What’s inside?

A Thermostatic Radiator Valve (TRV) is designed to automatically control the flow of hot water into a radiator to help regulate the temperature in a room. Inside the TRV there is a pin with a copper or rubber taper that sits on the valve seat and moves up or down to control the water flow. If the pin is sat against the valve it won’t let any water through, the further the pin goes up the more water it lets in. 

The clever part is the thermostatic part of the TRV. This is the big plastic bit on top of the valve that you turn to the desired number. Inside there is typically a metal coil that will expand and contract according to the temperature in the room. If the room is warm the coil will expand pushing the pin down so restricting the water flow. As the room gets colder the coil will contract, opening the pin to let more water through. 

Are TRVs all the same?

In principle TRVs are effectively all the same – they automatically control the individual heat output of the radiator they are connected to. However, there are different designs, shapes and colours to help with the aesthetic. Typically TRVs are white, but you can purchase chrome plated and brass TRVs if you want something different.

Most Thermostatic Radiator Valves are manually operated to choose the output. But you can go one step further with a smart radiator thermostat. This replaces the standard thermostatic head to create a WiFi controlled heating system that can become part of a smart home.

What’s the advantage of a TRV over a standard radiator valve?

The key advantage of a TRV is the automatic control of the hot water flow, which in turn helps control the temperature of a room. This makes them more energy efficient, environmentally-friendly and a money saver as you aren’t typically using as much energy to heat the water.

Standard manual radiator valves do not automatically control the hot water flow. They are set at a static point i.e. half open, which allows the same flow of hot water. To adjust you will need to do it manually, which makes then less efficient. 

Do I need a TRV in every room?

You can have a TRV in every room with a radiator as regulations state, but typically you don’t have a Thermostatic Radiator Valve in the room where the main thermostat controlling your boiler is located. So if you have your main thermostat in the kitchen you don’t need a TRV on the radiator in that room as the thermostat will be controlling the heat output for that room.

But in rooms where the main thermostat will have no control you should have a TRV to help keep a more even temperature. For example, if your main thermostat is in the kitchen and the temperature is warmer than normal the radiators in other rooms won’t come on, even if they are cold. 

What setting should a TRV be on?

This will depend on how often the room is used, but one of the benefits of a TRV is the control that they give you on a room by room basis. In a regularly used room like a lounge or bedroom you want to set the TRV to two or three – on a 0-5 scale – and see how that works.

If you feel that the temperature is too hot or too cold, adjust as necessary. Ideally you shouldn't need to turn up to number five. If you do the valve will constantly be open negating the benefits a TRV typically brings. Conversely, switching a TRV to zero means you are effectively switching off the radiator so it won’t warm up.

In a room that doesn't get as much use, so doesn’t need to be as warm as other rooms, set a TRV to two to start with and and turn up or down as necessary. This means you can keep an ambient temperature in the room which will help keep mould at bay. But if it does arise you will want to know how to remove mould from walls. 

What temperature is 5 on a TRV?

The numbers on a Thermostatic Radiator Valve commonly range from zero to five. These reflect the water flow through the valve. If your TRV is set to zero this means that the valve is closed and won't let any hot water through. If the TRV is set to five then the radiator is on more often.  

The approximate temperature for each number is as follows:

• 1 = 10°C
• 2 = 15°C
• 3 = 20°C
• 4 = 25°C
• 5 = 30°C

Choosing three or four should be more than enough to keep any room warm and toasty in the cold months. In the warmer months you can turn a TRV down to one or switch off altogether depending on how warm it is outside.  

Today’s generation of radiators are sleek, stylish and smart meter compatible. Not only do they look good, but they keep your house – and you – warm and help the environment. They are designed to help reduce the amount of energy consumed, which in turn reduces greenhouse gas emissions. 

And another big bonus is that once installed they require minimal maintenance. You don’t need to do more than call in your local heating engineer once a year to give your boiler a service and your radiators will be with you for years to come. 

Once upon a time regular everyday radiators were hardly the most exciting to look at. If you’ve decided it's time to upgrade your plain white radiators and swap them for something more modern, then you don’t have to look far to find a great selection of styles and colours to match any variety of interior décor.

They may well be functional, but do they complement your new radiators? You want to be thinking about colour matching or colour complementing your radiators with the perfect valve accessories. It’s the small details that can make a big difference to your finish.

And don't forget your central heating pipes. Were they previously painted to match, disguised with grey plastic piping, or perhaps you have copper pipes that need covering? Whatever radiator pipework you have, consider an upgrade to match with your new radiator with Radiator Outlet’s impressive online catalogue of radiator accessories. 

Finding the best space heater for your home will largely depend on the space you wish to heat, how many people in the room and how quickly you want to warm it. 

Naturally, budget should always be taken into consideration, and with heating costs increasing exponentially over the last few months only heating the spaces you need, rather than using the full-house central heating, is an option many are researching alongside other energy saving tips. 

With more people working remotely from home, or simply wanting to use less gas or oil, space heaters can be an appealing alternative. There are a couple of different types of space heater, so we've broken them down into which would work best in different situations to help you pick which is right for you. 

What is the best type of space heater for just one room?

If you're just heating one room either a halogen space heater or oil filled radiator will do the job well. 

The radiant heat of a halogen heater is ideal for warming something, be it a person or sofa, directly. This could be ideal for those working from home in a larger room to combat energy price rises as no energy is wasted raising the temperature of the entire room, simply the material or person that needs it.

Oil filled radiators would similarly be good for smaller rooms as they hold residual heat for longer, meaning less energy is needed to heat the space up. An oil filled radiator cost to run could be as little as 20p per hour, depending on the size. Plus, after the first burst of power supply they will gradually radiate heat, keeping the user at a comfortable temperature without being constantly on. 

What is the most effective type of space heater for large spaces?

Halogen heaters are the best space heater for one point of warmth in bigger rooms, and, while it sounds odd, will be one of the cheapest ways to heat a room as they are generally more cost-effective than putting the heating on. 

Typically the least expensive space heater to run, halogen heaters like this one from Argos often require 1200W of electricity, costing just 40p per hour based on current the electricity cap at 34p per kilowatt hour. 

However, if you're wanting to heat the whole of a large room, a fan heater might do the job better (more information below). 

What is the quickest space heater to warm up a room?

Fan heaters will warm a room up the fastest of all of the space heaters — making them ideal candidates for a quick bust of warmth while your central heating kicks in. 

However, once a fan heater is unplugged, the warm air stops and the room will just as quickly go cold once more. To achieve consistent warmth a fan heater has to be turned on constantly, which considering the average 2kW products will cost 68p an hour, this can quickly stack up in comparison to a halogen or smaller oil filled radiators. 

Infrared space heaters are generally more efficient than electric fan heaters, with some using just 300W of electricity.

What is the safest heater to leave unattended? 

Historically, it has never been a good idea to leave any space heater unattended, but recent developments in safety measures in products means that infrared heaters are safest to leave alone. 

Oil filled radiators also tend to be more stable than other types of space heaters. Thanks to their legs and larger, heavier design they're more difficult to tip over, but we still would not advice leaving it on overnight, just in case.

No matter what type of space heater you choose, look for products with either a maximum heat shut off, so it doesn't overheat, as well as ones with tip-over switches for added safety measures. 

A radiator leaking water from bottom is not an uncommon problem, but there is often a quick and relatively easy fix for confident DIYers. You might be really lucky and it's simply a tightening of a nut to solve the problem.

While most of us hope for the easiest of fixes it is more likely you will need to do a little more work. The first thing you want to do is identify the leak. Is it coming from the radiator, is it coming from the nut or from the valve itself. Once identified you can get it sorted.

After you’ve fixed your leak and replaced the radiator you will need to know how to bleed a radiator to get it back up to full working order.  

How to stop radiator leaking water from bottom

If your radiator is leaking from the bottom and leaving puddles on the floor it is typically a leaking valve that’s causing the problem. Here’s how to sort it.

1. Tighten the bolt
Radiator valves are attached to a radiator by a nut typically known as a union nut. A simple tightening of the nut may well sort out the issue. This is the first port of call and if you're lucky it will work. If not, it's on to the next solution.

2. Refit valve
The next option is to refit the valve. If the leak is coming from the union nut and the valve it may simply be a matter of adding or replacing PTFE tape around the thread. But before you can do this you will need to know how to isolate a radiator, which is effectively closing the valves on the radiator to stop the water flow and then drain. 

Once isolated, undo the union nut, drain the radiator and dry the thread on the valve when finshed. Now get the PTFE tape and wrap around the thread and do the union nut back up.

3. Replace the valve
If the radiator valve itself is leaking rather than the joint, then remove the old radiator valves and replace with a new one. You will need to check what size pipes you have, these are typically 15mm or 10mm depending on what system you have. Make sure to check out our how to fix a leaky radiator guide for more help with this.  

What do I need to do if it's not the radiator valve? 

If the radiator valve is not the problem then there may be a leak in the radiator itself. If you have an old radiator there may be a rust spot that has finally cracked. These are often found on painted radiators trying to hide rust spots. Look for areas that have bubbled up and place a dry finger on the area and see if it is wet.

Alternatively, note where the water is pooling and look up vertically. If it is the radiator, leaks will be close to the vertical line. Note it might be in the inside or the back of the radiator, making it harder to spot. If the radiator does prove to be leaking, it's time to replace the radiator. 

How much does it cost to replace a radiator? 

If you are replacing a single radiator on a DIY basis the cost will effectively be the cost of the radiator and new valves. Radiator prices vary depending on what type of radiator you are looking to buy. But a common sized (800mm/1000mm) single panel white radiator seen in a lot of homes will cost you around £50-£100. 

TRV valves cost around £10-£30 while basic lockshield valves cost around £5. You can pay more if you want something more than the basics, for instance these Tado smart TRVs costing £199.99 for three on Amazon. 

If you want to pay a plumber to remove and replace a radiator you should expect to pay around £150-£200 plus the cost of the radiator. If you want the radiator removed altogether expect to pay up to £100 for removal, disposal and capping the pipes.

If you are looking to replace more than a single radiator and do not have much experience working with radiators, you should seriously consider consulting a plumber to see how much they charge. 

Will turning off a radiator stop it leaking? 

Turning off a radiator will stop water flowing through the pipes and into the radiator. This is unlikely to stop any leaks as the water will still be sitting in the radiator and the valves, but it will slow down the leak as no water will be passing through.

However, once you have isolated a radiator you can undo the valves and drain the radiator. Make sure that you have enough containers and towels at the ready to catch the water. An average sized single panel radiator should release around 2-3 litres of water. A double panelled radiator will obviously release more, so be prepared. 

Obviously, an empty radiator means that any leaks from the radiator will stop and if the union nut was the problem then this will stop the leak. However, if the valve is the problem this may carry on leaking. Get a towel and wrap it around the radiator valve to help absorb any leaks.

A leak might be one reason that your radiators are not reaching their maximum temperature. But as with a lot of plumbing problems it's not always that simple. Check out our radiator not heating up quick fix guide for help with any heating and radiator issues.  

We’re all looking for ways to save money on our energy bills, especially when it comes to heating our homes as the temperature drops. The Black Friday deals are a prime opportunity to invest in an oil-filled radiator. 

As many of us work from home, trying to keep warm without having the heating on all day is a challenge. How much an oil-filled radiator costs to run is worth calculating as it will depend on the wattage, however using one can make a difference, heating just the room you are in. 

I work from home all week and it’s not viable to have the central heating on all day so I’ve recently wheeled out my trusty DeLonghi oil-filled radiator to keep the room I work in warm. And it works a treat, here's why I highly recommend doing the same.

 Why I use an oil-filled radiator

The model I have has a fairly slim profile and sits neatly next to me, emanating a nice constant heat. Although it’s a little heavy, it is on wheels, which means I can wheel it around easily enough to where I need it to be. My only gripe is that the cable isn’t that long so although you can position it, it’s a little restricted by where your plug socket is, unless you plug it into an extension lead.

I like the fact that it’s got a dual switch so I can choose to have it on a minimum or maximum heat when both switches are on. A simple dial can be turned up or down depending on the temperature output I need. And if you do the calculations, it costs me around 51p an hour to run my 1500W oil-filled radiator. While central heating can be cheaper to heat the entire house, just heating one room means I don't need to have the heating running for long periods of time. If I keep the doors closed it’ll heat the room up in around 20-30 minutes, depending on how cold it is, and will retain the heat for a while before clicking back on again.

The oil-filled radiator is quiet when turned on too — I can occasionally hear the oil crackling to heat up and a click when it turns itself back on, but other than that there’s no noise at all.

My model has now had an upgrade but Amazon sells a range of oil-filled radiators and there are some great deals to be had in the Black Friday sale.

Cold towel radiator? Then you need to know how to bleed a towel radiator to bring it back up to piping hot to keep your towels toasty. When air gets trapped in the heating system you'll notice your towel radiator isn't warming up properly — ordinarily being hot at the bottom and cold at the top.

Bleeding a radiator is the easy way to remove trapped air. A heating system is pressurised, so when the bleed valve is opened it forces the air out allowing the water to fill the radiator. 

But it is worth noting the reasons why air is getting into your system. There might be a leak somewhere, or your radiators need replacing. If it happens regularly you will need to call in a professional to help identify any issues.

But until then follow out quick and easy guide to stay warm.

How to bleed a towel radiator quickly 

To bleed a towel radiator you will need the right tool to help undo the bleed valve. For this job you can use a standard radiator key or a flat head screwdriver. 

1. Turn off the heating and switch on the radiator valves

The first step is to ensure your heating is turned off and the towel radiator has cooled down.

A towel radiator will need to be filled with water to bleed properly. Typically there will be two valves on the bottom which allow water into the radiator. You need to make sure that these are both open.

If your towel radiator is equipped with a TRV (Thermostatic Radiator Valve) turn it up to the max (typically number 5). If you have valve caps that twist, turn anti-clockwise. If the caps are just covers, pop off and use a pair of pliers to turn the valve anti-clockwise.

2. Open the bleed valve
First locate the bleed valve. This is typically on top of the radiator and will have a small square screw in the centre with a slot on top. There will also be a small hole in the bleed valve where the water comes out when you open it. 

Get a towel or cloth and wrap around the bleed valve and get a small container to capture the water

Now get your radiator key – or if you don’t have one, a slotted screwdriver – and slowly turn the screw until you hear air hissing out. As soon as this happens get ready to catch any water. Quickly close when the hissing stops.

3. Repressurise heating system
After letting air out of the system, the pressure on the heating system will drop. If you have a pressurised boiler you may need to repressurise the system to get it back up to optimum working order. The process is different depending on what system and what manufacturer you have. 

If you don’t know how to repressurise your boiler, locate the instruction manual and see how it's done. If unsure, contact a professional. 

What are the two valves on top of a towel radiator for? 

These are not valves in the same sense that they control the water flow in and out of the radiator. One is a vent valve, which is known as the bleed valve, which releases trapped air.

The other is known as a blanking plug. This effectively seals up the other hole in the top of the towel radiator. This simply screws in the top of the radiator. You will need an adjustable spanner to insert or replace.

How much will a plumber charge to bleed a radiator?

If you follow this guide you wont need to call out a plumber to bleed your towel radiator. However, heating a bathroom is essential when the winter months close in. When bleeding your towel radiator it will be a good time to do all the radiators in your home.

If you are not confident doing this yourself you can call in a plumber, or potentially combine this with your annual boiler service. The price will depend on how many radiators that you have. If you have less than 10 radiators the job should take an hour or two or less. Expect to pay around £80-£100.

If you have more than 10 radiators the job will obviously take longer, maybe around two to three hours expect to pay £100-£150.

With the cost of energy soaring we’re all looking for the cheapest way to heat a room. And with government figures suggesting that over 42 per cent of us now have smart meters, most of us can watch in real time exactly how fast our money is being spent. 

There are several reasons for record energy prices. It’s partly the recovery from the pandemic, which raised demand higher than supplies could follow, not to mention energy-producing Russia’s war on Ukraine. The result is that the average unit price from October for customers on standard variable tariffs is 34p per kilowatt hour (kWh) for electricity and 10.3p kWh for gas. Conserving energy and energy saving tips have never felt so important.

We spoke to heating expert Rob Bohm, from heating consultants CLPM, to pull together this comprehensive guide on the cheapest way to heat a room.

What type of heating system is the cheapest?

Gas central heating is the cheapest type of heater to run, most householders will be pleased to hear given this is the most common heating fuel across the UK. "For most, gas will still be the cheaper way of heating," agrees Rob Bohm.

Looking at the annual average cost of a range of heating options – taken from a typical three-bedroomed, semi-detached home, using approximately 16,000 kWh – gas costs an annual average of £910 for households, according to data from Oftec. 

This is by far the cheapest heating option compared to others, although it is worth noting that this data was compiled earlier this year so energy prices have likely increased since then.

Electricity meanwhile is far more expensive, costing households an annual average of £3,246, a heat pump with underfloor heating comes in at £2,168, an oil boiler at £1,422, and a heat pump with radiators £2,585.

When applying these guides to your own home, there are three factors, as identified by Oftec, that affect how expensive your heating system might be to run:

• Unit cost of the fuel your home uses
• How efficient your heating system is to run
• Heating requirements of your house and occupants (biggest variable)

With 78 per cent of UK housing stock having gas central heating according to Statistica – covering an estimated 23 million homes – the gas boiler remains the cheapest orthodox way to heat your home. 

"One thing is for sure though. The cost of energy will continue to rise and the gap between the cost of electricity and the cost of gas is sure to close," cautions David Hilton of Heat and Energy.

"At the moment the switch from gas to a heat pump may not make financial sense, but as the energy cost gap closes, the numbers will certainly become more favourable for heat pumps."

There other caveats too, and Rob Bohm of heating consultancy CLPM urges everyone to look beyond the heat source and adopt a 'fabric first' approach. This means looking at your home to find strategic ways to reduce your heating requirements, primarily by properly insulating and draught proofing your house. 

When it comes to the central heating, there are however some simple ways to bring costs down. If you don’t have them already fit TRVs (thermostatic radiator valves) on radiators, which automatically detect the room temperature and turn heat up or down accordingly. You don't have to favour function over style anymore either like this traditional TRV from Trade Direct.

The next step in the same direction is to buy smart TRVs, which can be controlled from a smartphone, giving you the ability to turn down the temperature in unused rooms by the touch of a button. This smart TRV by Drayton Wiser can also be controlled via an Alexa or Google Home.

Underfloor heating is another option. Once considered a luxury but now routine, its cost will depend on whether it is electric or linked to a gas boiler. If the latter, UFH could cost 25% less than radiators to run and for the 2 per cent of us who have heat pumps it could be as much as 40% cheaper, according to Homebuilding's energy efficiency expert Tim Pullen in our underfloor heating guide. 

But as Rob Bohm explains, underfloor heating is typically best in new fit-outs, as retrofitting it into older homes can bring higher installation costs. 

What type of heater is the most expensive to run?

Electric heaters of all types are the most expensive. This is due to the high cost of electricity at 34p per kWh on a standard rate. 

For indirect electric heaters – for instances radiators connected to an electric boiler – this cost is an annual average of £3,246, according to estimates from Oftec as mentioned above.

Even if an electric system is heated by an off-peak Economy 7 tariff at 20p per kWh (and therefore only costing 40p an hour to run), the cost will still be far more expensive than gas, which is only 10.3p per kWh even after recent price hikes.

Direct electric heaters – panel heaters, electric fan heaters etc – are particularly expensive. 

Wall panel heaters

Wall-panel electric heaters can be costly, especially if these are used throughout the house and have high wattage. A house with four 3kW wall panel heaters would cost £4.08 to run each hour ((£0.34 x 3kW = £1.02 per kWh) x 4 = £4.08). 

But storage heaters, which charge overnight on Economy Seven tariffs and release heat during the day, can be an effective solution, particularly for those that don’t have access to mains gas. 

Infrared heating

Infrared heating is a newer technology; it works by targeting heat at solid objects.  

A 500W infrared heater would have a running cost of 17p at current electricity rates (£0.34 x 0.5kW = £0.68 per kWh). But as Bohm says, they work best in localised environments. 

“The only way an infrared heater can be a bonus is if you’re in front of it,” he suggests “They work better in commercial applications like village halls or churches where you want to hit the congregation but not the whole room — less so in a domestic scenario.”

Electric fan heaters

A typical electric fan heater with 2kW of power would cost 68p per hour to run at full power at current prices (£0.34 x 2kW = £0.68 per kWh), and even more if those increase in April 2023. 

While some opt for fan heaters because they heat a room up quickly, it depends on the level and quality of your insulation as to whether the heat is retained. “The moment you turn them off you start to get cold,” Rob Bohm points out. If you are using an electricity driven oil-fired radiator, at least it will stay hotter for longer. 

Oil-filled radiators

Some – particularly the estimated 22 per cent who sometimes work at home – carry round electric heaters, including oil radiators, fan heaters and halogen heaters. These may seem like a saving, as they only heat one space at a time, but this may not necessarily constitute a saving. With oil-filled radiators, for example, a 500W radiator will cost 17p to run each hour at current 34p per kWh rate.

How can I save money when heating my home?

There is no ‘silver bullet’ says Rob Bohm. Go 'fabric first', look at your home and devise a strategy. “There are three key factors,” he adds. “How big your room or rooms are; what your insulation levels are like; then draught proofing. The way these factors interact is vital to your energy saving solution.”

Insulating a loft is critical: install 300mm of material such as mineral wool insulation. Then check windows, doors and even things like broken cat flaps, keyholes and letterboxes. Bohm suggests checking each weak point by holding the back of your hand around leaky frames. Buy stick on seals to keep draughts out (this weather proofing seal on Amazon is cheap and easy to use), use curtains, carpets and rugs to add warmth.

Wall insulation – internal, external or cavity wall – and floor insulation should ideally be added, but the capital cost for this can be much higher. And before you do so, do a survey — in some older properties, products applied in unsuitable ways can cause problems such as condensation. 

Don’t forget some lower-tech ‘hacks’ such as bubble wrapping windows, installing heating controls such as TRVs, and making your radiators more efficient by bleeding them regularly and ensuring they're balanced. 

And don’t forget to go around all your thermostatic radiator valves and turn them to low — Bohm says a general rule of thumb is about 12-14 degrees to keep it ticking over.

Having the best radiators – and only the best – is a smart investment that will last for years. But with so many options and specifications to navigate, it can be tricky to know which model is right for your home.

Whether you prefer a wall-mounted or floor-standing design, radiators come in various sizes, colours, and power outputs to efficiently heat your home. While panel models are sleek and modern and can be bought as a double to boost heat output, column radiators are typically more traditional and can have a deeper width for more heat.

To help, we've included some advice from industry experts, applied our own knowledge and compared radiator spec to narrow down your search to just nine options. If you specifically want a new radiator for the bathroom, check out our guide to the best bathroom radiators, too.

The quick list

Short on time? Don't worry – we've put together a handy overview of the best radiators on our shortlist for a quick checkout, along with a way to jump down the page if you want more details.

The best radiator overall

There are plenty of reasons why the Milano Windsor Horizontal Double Column Radiator is our number one pick. It's the perfect choice for anyone looking to replicate the look of a traditional cast iron radiator – without the weight or price tag usually associated with column models.

The 1.5mm-thick, premium-quality steel construction ensures that heat is efficiently distributed through the columns and into your room, while the white powder-coated finish complements both traditional and classic contemporary interior schemes alike.

Another bonus of this radiator is that it can be combined with other models from the range for a cohesive look – including the tall vertical design (available on Amazon), which works well in awkward spaces. We can’t really think of anything negative to say, so it gets our vote for the best radiator you can buy.

The best contemporary radiator

This stylish radiator from NRG boasts a contemporary design that fits seamlessly with modern and minimalist home interiors.

Not only is it eye-catching, but it’s extremely durable too – made from 1.5mm premium mild steel with a high-quality white finish. It’s no surprise, therefore, that this model comes with a 15-year manufacturer’s guarantee.

Given its 180 x 35.4 x 7.8cm size (with multiple size options available), you certainly get great value for money, making it a smart choice for anyone planning a renovation or conversion on a budget. Brackets and fixings are included, but valves are not.

• Back to the top ⤴

The best small radiator

The Milano Aruba comes in a variety of sizes, but we particularly love the 400 × 415mm model, which is smart, compact, and includes a blanking plug, bleed plug, and wall fixings. Made from extra-thick, low-carbon steel, the manufacturer is so confident in its durability that it comes with a 20-year guarantee.

Despite its dinky dimensions, it generates an impressive heat output of 1,170 BTU, making it ideal for small spaces, awkwardly shaped rooms, or for fitting neatly beneath window sills.

While it might cost a little more than some other compact radiators, it offers a sleek, contemporary appearance that more than makes up for the extra expense.

• Back to the top ⤴

The best designer radiator

As the name suggests, this vertical radiator really is an elegant way to heat a room.

It’s an ideal option for awkward spaces and would look particularly stylish in a kitchen or hallway – both rooms where wall space is often at a premium. It’s available in single or double formats.

This is another radiator with a high BTU output (6,500–6,900), making it a strong choice for medium to large-sized rooms. Do make sure to get help lifting this one, though, as it’s a little heavier than some in the line-up, and its height and width can make it tricky for one person to carry.

It comes with wall brackets, a plug, and a vent, though valves need to be purchased separately.

• Back to the top ⤴

The best budget-friendly radiator

While this compact radiator from Milano might not make the shortlist for its eye-catching good looks, it actually has quite a lot going for it. In fact, many people will be drawn to its ability to simply sit unnoticed within an interior scheme.

This is an excellent compact radiator for small spaces, measuring just 60 x 40cm. It’s lightweight too, meaning even relatively non-substantial walls can support it easily – plus, it delivers an impressive heat output of 1,202 BTU.

In short, this is an ideal radiator for anyone on a budget, whether you’re replacing old radiators as part of a heating system upgrade or starting from scratch.

• Back to the top ⤴

The best electric radiator

The Devola Glass Panel Heater proves that electric radiators are anything but boring. It’s available in a choice of black, white, or grey finishes, as well as with alternative heat outputs. In this case, a single 1500W heater can warm a 17-square-metre room.

As well as looking smart, it is smart. Being Wi-Fi enabled, it allows you to control it from anywhere using your smartphone. It can be operated via voice assistants such as Alexa or Google Home, or through the dedicated app.

Another benefit of this radiator is how easy it is to install – use it as a freestanding unit or simply mount it on the wall. With either option, you’ll just need to ensure there’s an electrical socket within 1.5 metres. Its splash-proof design is IP24 rated, meaning you can even install it in a bathroom, although you’ll need to call in a qualified engineer if this is your chosen location.

• Back to the top ⤴

The best flat panel model

Crisp and modern in form, and available in a wide range of sizes and configurations, this smart flat-panel radiator comes with all the brackets and fittings needed for installation (you’ll just need to purchase the valves).

This model is compatible with all UK heating systems, including tank-fed and combi setups, and reviewers were impressed by how quickly it warms up.

On the downside, this radiator is relatively heavy compared to some of the other models here (weighing 13.8kg), despite being made from 1.5mm premium mild steel. This will, of course, depend on the size you choose – but it’s something to keep in mind if you’re planning a DIY installation.

• Back to the top ⤴

The best kitchen radiator

If you’re looking to minimise the amount of wall space taken up by your radiator, or are working with awkward areas – such as kitchens and bathrooms – this design would be a great choice.

Super sleek and contemporary in form, the matt anthracite finish makes a striking modern statement while remaining subtle enough to blend with a range of interior styles. Made from low-carbon steel, the radiator is also praised for its ease of installation.

However, it may not be the best option for those on a tight budget.

• Back to the top ⤴

The best oil-filled radiator

Oil-filled radiators have increased in popularity over the last couple of years, with more of us working from home and keen not to turn on central heating when just one room needs warming rather than the whole house.

Oil-filled radiators work by using electricity to heat oil via an element inside a reservoir. When the element heats up, warmth is transferred to the oil, which then circulates through the appliance, warming its metallic panels.

The De'Longhi TRNS0505M Oil-Filled Radiator is a great model to consider. It is easy to move around the house thanks to its large, sturdy handles and lightweight design. However, it's worth bearing in mind that it doesn't have any wheels.

Its light modern white finish and subtle styling make it one of the better-looking offerings on the market, and it delivers an impressive heat output (500 Watts) – plus it heats up very quickly. This model can heat a space of up to 15 cubic meters and has been praised for being quieter than other oil-filled radiators on the market.

How to choose the best radiator

There are several factors to consider when choosing radiators which go beyond just setting a budget.

1. Calculate the BTU (British Thermal Unit):
“All radiators have a specified heat output so once you know how much heat the room needs you can choose the type, size and style to suit your taste and the room,” says energy-efficiency expert Tim Pullen.

Online BTU calculators (see manufacturers’ and suppliers’ websites) will help to give an indication of the output. Factors considered include; room dimensions, size of window openings and number of external walls present. For more information, read our guide that answers what are BTUs.

2. Measure up:
The size of radiator can impact the heat output, and you'll find that some manufacturers offer different sizes in their radiator designs. If, however, you’re stuck for space or simply prefer to be without radiators, skirting board heating is a discreet, space-saving alternative.

3. Consider the location, weight and preferred eco-credentials:
Colours and materials can also vary between radiators so you'll need to consider these three things. Steel or cast iron radiators are mega heavy so consider the wall type they will be mounted on, and who will be installing a radiator.

“Aluminum options are usually the most effective in terms of efficiency and they are the ‘greenest’ in terms of their manufacture,” explains Dave Thornback, UK Sales Manager at Vasco. “Added to the fact that they can be completely recycled at the end of their life.”

4. Choose your design:
You can have a lot of fun choosing the size and shape of a rad, but just be mindful to ensure you're going to be achieving the desired heat output for the space.

5. Set a budget:
After considering all this you can narrow down you search and set a budget, or think about how much you are prepared to pay. The cost of radiators can run into the thousands-of-pounds so it would be prudent to weigh up all of the factors above with how many new radiators you need, before heading to the check out.

FAQs

What is a BTU?

Design and budget are foremost factors, but in order to choose the best radiator for your room, you will need to determine the heat requirements of the space.

Room sizes, window dimensions and even the materials used in the walls will all be used to calculate the required outputs of the radiators you will need to heat the room properly.

You will notice that radiators have a 'BTU rating'. BTUs are ‘British Thermal Units’ and this is the unit in which radiator efficiency is measured.

A heating engineer or plumber should be able to work this out for you, or you could use an online BTU calculator.

Our handy guide to to help you find a plumber for your project is a must-read.

Electric vs plumbed-in radiators: Which is best?

Before you begin your search, decide whether you will need electric radiators or those that are plumbed in.

Electric radiators use mains electricity. Some are designed to be plugged into a socket, while others will need to be fitted by an electrician. You might also see infrared electric radiators for sale. These are good for small spaces as they have a high heat output with a slim profile.

Plumbed-in radiators are connected to your boiler and use hot water as their heat source. They’re controlled as part of the central heating system.

What are the different radiator types?

Here are the most common types of radiator and what they do:

• Side panel radiator: These basic horizontal radiators run off the central heating and are wall mounted.
• Double panel radiator: Made up of two single panel radiators, these are also wall mounted but have a greater heat output.
• Column radiator: A great way to add some character and charm to a home, while also providing warmth. They take up more space than panel radiators, but offer good heat output.
• Vertical radiator: If you're heating a more "creative" space then a vertical radiator is an option. They can also be known as "upright radiators" which are tall and narrow, making a great design statement.
• Heated towel rails: These are designed for drying and heating towels, geared towards being located in the bathroom. They can either run off the central heating or the electrics.

Have ever-rising energy prices got you wondering about oil-filled radiator running costs? Not only are these heat sources popular with those working from home, but they are also often seen as a pocket-friendly option for anyone keen to limit how much they use their central heating in the face of rising energy prices. 

Energy costs are still at the forefront of many people's minds. This is partly down to the fact that working from home and hybrid working is now more common than ever, but also because of the cost of energy. 

Being at home more translates into bigger domestic energy bills meaning now really is the time to be swotting up on as many energy-saving tips as possible, particularly as we wave goodbye to summer.

So, with an increasing number of remote workers now relying on an oil-filled radiator to warm up their work spaces, is this something you should be considering? In this article we explore how these heaters work and how much they really cost to run.

Best deals on oil-filled radiators

How do oil-filled radiators work?

First things first, what is an oil-filled radiator? They work by using electricity to heat oil with an element inside a reservoir. When the element heats up, the warmth is transferred to the fluid, which then circulates around the appliance and warms its metallic panels. None of the oil is burned as fuel.

The radiator starts heating the air already in the room. When the air gets hot it rises and shifts the cold air to the floor.

They can be installed on a wall just like standard types of radiator or can be freestanding units that can be moved to different rooms. The ability to heat just one room is the reason many advise that homeworkers give them a go.

They’re also safer than some portable heaters because there is no element that could be a fire hazard and are very quiet, so won’t disturb you while you try to meet deadlines or are just trying to relax in front of the telly. Many people have them by their feet beneath or next to their desk or table.

How much do oil-filled radiators cost to run?

The big question — how much do these radiators cost to run? While this will obviously vary depending on the size and type of your oil-filled radiator, there are ways of calculating the running costs of the models you are interested in. 

Smaller oil heaters can use as little as 500W of power (possibly less) and are designed to heat smaller rooms — while larger oil heaters can use 2,500W or more. 

For three months, as from 1 October, electricity is being charged ar a unit rate of Unit rate: 27p per kWh and you can use this figure to work out the cost of your oil-filled radiator.

Start by converting the watts into kilowatts and then multiply by your electricity cost per kWh. You can do this by dividing the watts by 1,000 and then multiplying by the current electricity cost. 

For example, a 500W radiator will cost just over 13p to run each hour under current 27p per kWh rates (500/1000 = 0.5, then 0.5 x 27 = 13.5).

How much an oil-filled radiator costs to run is also dependent on a few other factors. The following will all affect the running costs: 

• the type of home you live in and level of insulation in the property
• the size of room where it will be used
• your energy provider
• your boiler type
• the time it will be used.

Are oil heaters cheap to run?

In general, oil-filled radiators are more economical to run than many other types of heater due to the fact that oil retains the heat well. This makes it more efficient than an electric convection heater, according to Qbic Heating. 

Electric oil-filled radiators may also offer programmable heating controls that give you the flexibility to create a heating routine tailored to your needs. This ensures you are achieving an optimal temperature when it is needed and preventing heat being wasted in unused space, which can happen when turning on the central heating for the entire home.

Electric oil-filled radiators are portable so you can heat only the room you are using to reduce your energy costs.

Oil-filled radiator vs central heating

Where you only want to heat a single room, such as your home office, oil heaters will usually make more sense than turning on the central heating. However, if you need to heat your entire house, you are better off using central heating, providing you have a fairly efficient emitters such underfloor heating and an efficient boiler.

Radiators under windows — just what are they doing there and why are they so common? Here, we take a look at why beneath the window was such a popular spot to mount radiators and ask the experts out there whether this is still such a good idea.

These days there are so many types of radiator out there to choose from, meaning there are designs for all kinds of homes and spaces, including those created with small rooms in mind and for awkward spots too. What this means is that we are not so limited as to where to place radiators these days. 

In addition, our homes have become far more thermally efficient than they were in the past, meaning our heating requirements and the kind of considerations we have to give to heat loss have changed dramatically.

So, do both of these factors mean that radiators under windows should become a thing of the past or is there still a good reason to carry the trend forward?

Why are radiators under windows so common?

Although many people these days shun the idea of placing radiators under windows, there was once a very good reason why people used to do this and why it was once recommended as a good idea.

"Before double glazing was introduced and windows were mainly single glazed, the window was the coldest area of a room," explains Mark Wilkins, Technologies and Training Director at Valliant. "By placing a radiator directly underneath the window, hot air is produced and released, which then rises to hit the cold air from the window. This creates a warm curtain of air over the window surface."

In addition to this reason, very often the space under a window was the only clear area of wall on which to hang a radiator where it wouldn't be covered by an item of furniture. Of course these days, the best designer radiators are often made with awkward spaces in mind. 

Is it still a good idea to put radiators under windows?

Despite often being viewed as an out-of-date idea, there is actually nothing wrong with placing radiators under the window and in some cases it can still be the best option — even for those with triple glazed windows.

"The best place to put a radiator is in the coldest spot of a room. If you live in an older home with single glazed windows, it's a good idea to put your radiator underneath the window to counteract the cold air coming inside," explains Tom Drake, heating expert at Only Radiators. "The cold air then helps the heat from the radiator to move around the room, keeping the room warmer than if the radiator was placed somewhere else."

That said, if your windows are double or triple glazed, you have much more choice when it comes to positioning your radiators. 

"These days, most windows are double or triple glazed, heat isn’t lost as quickly through these types of window and the area close to the window surface stays much warmer," says Mark Wilkins. "Therefore, it’s not as common to see radiators under windows in new builds or modern homes as there can be more flexibility here."

Are there any rules for radiator placement?

In general, the most sensible place to mount a radiator is in the coldest part of a room.

"Modern homes, with better insulation and double glazing, may not have the same cold spots as old houses, so radiators wouldn't necessarily need to go below windows," says Tom Drake. "However, many households still choose to place radiators under windows as this is an area where furniture can't fit so it makes use of an otherwise empty space."

When planning your radiator placement, along with taking into account cold spots, do be sure that your room's layout won't mean the radiator will be covered by anything that could block heat, such as large items of furniture. Placing the radiator behind a door that will cover it when open should also be avoided. 

Finally, if you do decide to place your radiator under a window, you will need to think your choice of window covering through more carefully than if you fix it elsewhere — thick, heavy, floor length curtains are a great way of insulating windows and keeping heat in a room, but they will also prevent the heat produced by your radiator from entering the room.

Either choose curtains that end before the radiator or opt for blinds or shutters instead. 

"If your radiator sits beneath a window, you may feel inclined to tuck your curtains behind the heater so as to not trap any hot air," says Mark Wilkins. "However, many modern radiators use the back panels as part of their heat output, so this would restrict the flow of warm air into the room. We recommend opting for short curtains which would eliminate the issue or, if longer curtains are preferred, keeping them to the side of the radiator as much as possible."

Do radiator covers block heat? It is a common question asked by those looking for a way to conceal their heating source or to improve the decor of a room that is currently being spoilt by a boring or dated radiator. 

There are many different types of radiator and some are far more attractive than others. If you are renovating a house you may well find that, while the radiators chosen by the previous owners are in perfect working order, they may not make the most stylish design impact on the space. Or perhaps you are trying to save money and only have the budget for standard panel radiators but would rather they remain out of sight. 

Whatever your reasons for fitting radiator covers, it is important to understand the effect they could have on how well your radiators perform — you really don't want to be paying to warm up your home only to block most of that heat from reaching you. Particularly in an age of spiralling energy costs.

Here, we take a look at whether the common belief that radiator covers block heat is true or simply a lot of hot air.

Do radiator covers block heat from a room?

Before we can take a more in depth look at whether radiator covers prevent heat from permeating a room, it is useful to look at how radiators work. 

Put very simply, radiators take the heat from the hot water inside them and transfer it into the room they are fitted in. 

"Radiators get warm as the heat travels through the conducting metal of the radiator then, through the convection process, the area around the radiator is heated," explains Polly Shearer, heating expert at Only Radiators. "The more powerful your radiator, the more warmth will be spread around the room." 

Convection occurs when the warmth produced by the radiator moves into the air, before that air rises up and gets circulated around the room. 

Radiator covers do exactly what the name suggests — they cover the radiator. But does this stop the heat produced entirely or will it find a way through?

"Of course, putting a solid object around your heat source will have an effect on the heat output as it acts as a barrier," says Polly Shearer. "However, a radiator cover will not block too much heat as long as your cover has gaps and slots for heat to escape, and warm the air up through convection. 

"If your radiator cover is completely solid, you’ll be losing heat and energy, which will be more expensive as your boiler will work harder to reach the temperature set by your thermostat."

When thinking about how to optimise the performance of your radiators, be sure to design your layout so that no bulky items of furniture are placed in front of them either, and familiarise yourself with how to bleed a radiator in order to keep them running at their best.

Which are the best radiator covers for heat?

"The reality of the story is, an uncovered radiator will have a higher heat output and work more efficiently if it doesn't have the barrier of a radiator cover," says Polly Shearer. 

However, it is important to bear in mind that not all radiator covers are created equal — meaning some designs will block more heat than others. There are also a few tricks to make sure your radiator cover doesn't stop heat entering the room. 

According to Homeserve, fitting a radiator cover with a reflective foil backing can really help things, while opting for a design with a louvred front panel or one with plenty of slots and gaps will ensure heat is still able to enter the room. You should also ensure that the cover is not too tight a fit around your radiator to allow air to circulate. 

And when it comes to the best materials for radiator covers, which are best? 

"Wood is the most common material for a radiator cover, even though it isn't a very good conductor of heat," says Polly Shearer. "It is the best material to childproof your radiators — it won't get as warm as other materials like metal, and will absorb some of the heat. Galvanised metal is a great material for heat conduction and will ensure no heat is lost, but this isn't one for protecting your kids from burns!"

What is the best way to fit radiator covers to prevent heat loss?

It is not just the type of radiator cover that can have an effect on how much heat they stop from entering a room — it is the way in which they are installed too. 

Before you buy a radiator cover, it is important to take into account the space required between the radiator and the cover to ensure heat is allowed to circulate. 

"The gap between the radiator and the cover should be at least 5cm in width, 3cm in height and 3cm in depth to ensure it won’t affect the BTU output," says Polly Shearer. 

To ensure you buy the correct size of radiator cover, measure the length of your radiator (including valves), its height and the depth from the wall. You will also need to measure skirting boards and any window ledges. When you have these measurements add 5cm to the width, and 3cm to the height and depth. 

Finally, be sure not to cover your radiator and its cover with any large, solid items of furniture such as a sofa — this will only serve to block heat even more. 

What are the benefits of radiator covers?

Radiator covers do block some heat from radiators, so if you have gone to the trouble of sourcing the best radiators around it does not necessarily make sense to cover them. However, it is clear that well-designed radiator covers, with plenty of holes and gaps for heat to escape through, will have little impact on heat output.

There are also some real benefits to fitting radiator covers, including:

• Safety: If you live in a household with young children or pets, installing radiator covers can reduce the risk of burns. Some radiators can get really hot to touch which could cause serious harm — fitting a cover will remove this worry.
• Appearance: If your budget doesn't stretch to replacing boring or tired-looking old radiators with new designer or column models, radiator covers are a more cost-effective and easy way to instantly refresh the decor of a room.
• Storage spot: Radiator covers give you an instant shelf above — perfect for displaying ornaments or other decorative items in living rooms and bedrooms or as a place to keep bowls of keys, post and other essentials in hallways.
• Protection: As well as hiding your radiators, covers can also protect them from damage — pipework and valves can be prone to being knocked and kicked in high traffic areas so installing a cover could prolong their life. 

When it's time for maintenance, repairs, or upgrades to your heating system, you’ll need to isolate a radiator to stop water from spilling everywhere and ruining your carpet or flooring. It's a straightforward process that prevents water from flowing through a radiator.

However, you’ll need to be careful, especially when removing a radiator from the wall. You’ll need to make sure that you have buckets and towels at the ready to catch any water. Here, you’ll find out what tools you need, what the valves on a radiator do, and how to switch them off correctly.

How to isolate a radiator: Tools you’ll need 

You will only need a few tools, but make sure that you have them ready before you start. You'll need:

• Adjustable spanner
• Bucket/container
• Water pump pliers
• Bleed key (optional)

Try these tools to isolate a radiator

Identify valves on radiator

There are many types of radiators, but they typically have one thing in common — two valves, as Nicholas Auckland, heating, cooling and energy expert at Trade Radiators," shares, "Most radiators in our homes will have two valves, one at each end. These valves regulate the flow of hot water entering and leaving the radiator."

Auckland points out that one side will typically be a TRV or manual valve. “This is the control side, and the one you usually adjust.” He adds, “A TRV (thermostatic radiator valve) lets you set the radiator to a chosen temperature, which will usually be displayed as a number on the valve itself."

"The two perform the same task but operate slightly differently, points out Auckland, “A TRV automatically regulates the flow of hot water to maintain a comfortable room temperature. On the other hand, a manual valve is a simple on/off valve. You either open or close it by hand to let water into the radiator or keep it out. A TRV is recommended for the highest efficiency."

The other side is known as a lockshield valve. Auckland explains what it does, “This is the balancing side, and is usually covered with a plastic cap because it’s not something that you need to adjust every day."

He adds, "It's set up by radiator/heating installers to balance the system, making sure that every radiator gets its fair share of hot water. You realistically shouldn't need to do anything with this valve unless you want to isolate your radiator".

Steps to isolate a radiator

1. Be prepared

They might not be needed, but have a couple of containers and towels ready if you are going to remove the radiator after isolation. Wrap the towels around the water pipes and place the bowls under the valves.

2. Isolate the water supply

This is a straightforward process. If you have a thermostatic valve, turn it to zero. If you have a manual valve, remove the plastic cap and use a pair of pliers or grips to turn clockwise until the valve is closed. Then, do the same with the lockshield valve and ensure it is also closed. Job done. Now you can begin the process of removing the radiator.

Check radiator is isolated

Once you have closed the two valves, the water supply to the radiator will stop. The thermostatic or manual valve, which controls the temperature, should be set to zero. This means that the radiator will cool down and remain cold, as no water will be able to reach it.

The lockshield valve by default is left open to let the water flow through the radiator. The lockshield valve is part of the process for balancing radiators to achieve an even temperature throughout a home. Turn this clockwise until closed to stop the water flow.

FAQs

Does isolating a radiator stop it leaking? 

Yes and no – knowing how to fix a leaky radiator will stop the water supply from the pipes, but isolating the radiator may not stop the leak. It very much depends on where the leak is located.

If the leak is located on the radiator itself – this typically applies to old and rusting radiators that have been painted – then isolating the radiator won’t help. You will need to remove the radiator and replace.

However, if the leak is in one of the valves it will depend on what part of the valve. For example, if the olive on the water pipe joint is worn the leak won't stop when the valve is turned off.

Can you remove a radiator and still use the central heating? 

Yes you can. If you are looking to paint behind a radiator or replace an old radiator with a new one you first need to make sure that both valves are turned off. The water will then bypass the radiator and flow through to the next radiator in the central heating system.

Ideally you should only remove one radiator at a time. Two is OK, but it is best not to remove any more at any one time. This can cause the pressure to go up which can damage the heating system.

Radiators are designed to heat every room in your home, but are they the best option for loft conversion heating? You might want to consider underfloor heating. If you decide to stick with your radiators but don’t like their look, consider these radiator cover ideas to get the look you want.

Your kitchen radiator ideas should be something at the forefront of your mind when coming up with a new kitchen design scheme — they need not only to provide an effective way of heating the space, but also have to fit in with the overall style of the room.

There are many different types of radiator you can choose for a kitchen, but some are better suited to this room than others. The kitchen is, after all, a room with a lot of demands that other areas of the house don't have. 

While many people do opt for underfloor heating in the kitchen – and this is a great option – do bear in mind that providing somewhere to hang damp tea towels can be really handy. Many modern radiators are designed specifically for kitchens, and come complete with hooks and rails for this very purpose. 

Our selection of ideas covers everything from designs created to make a strong style statement, to those that will blend in seamlessly. 

Tailoring your kitchen radiator ideas

It is important to bear in mind that heating a kitchen can be quite different to heating other rooms in your house. Kitchens can often get quite hot without the heating being on when ovens and hobs are being used, along with other appliances such as dishwashers.

It is always necessary to calculate the correct heating requirements of a room before settling on a size and style of radiator in order to ensure it will give off the right amount of heat for the space, but in the kitchen it is particularly important to ensure the room doesn't overheat. 

For this reason, speak to your supplier about what the BTU (British thermal units) requirements of your room will be, or use an online BTU calculator to work out the size of radiator that is going to be most suitable.

Your radiator choice will also need to be based on the design of the space — standard radiators are not always the best option in a room where walls are often taken up by units or seating. For this reason, many kitchen radiators come in shapes and designs that are based on tackling the issue of awkward spaces.

1. Allow your kitchen design to shine

If you are keen to ensure your kitchen radiator doesn't draw attention away from your carefully planned-out kitchen design, then opt for a style that is subtle in both its form as well as in colour.

White is an obvious choice, while slimline, tall, narrow radiators make sense both visually as well as from a practical perspective, slotting in between units and items of furniture and requiring little in the way of floor and wall space.

The Ancona from The Radiator Company, shown here, comes in a vast range of sizes and column options and can be both vertically and horizontally mounted.  

2. Give tea towels a place to dry out

Practicality should be a priority in the kitchen — and your choice of radiator can help here. As well as keeping the room warm and cosy, it makes sense to pick a design that is built to hold and dry out damp hand and tea towels, aprons and oven gloves.

Here, the Griffin from The Radiator Company, in a smart matt grey finish, offers plenty of hanging space as well as looking super sleek and stylish. Better still, it comes in 15 different sizes.

3. Opt for a wooden finish for warmth

Wooden finishes offer a warm and charm that is hard to match — but you may not have considered wood as a radiator material. The Tulipi from Viadurini is a hydraulic designer radiator with a real wood surface concealing the steel skeleton beneath.

Turning your radiator into a talking point by opting for wood is a great idea — plus wood works with all kinds of kitchen styles, so is a great option for those after modern kitchen ideas as well as those who might be set on a more classic look, such as a Shaker design.

4. Go for classic style with a column radiator

Column radiators have timeless appeal and are now available in all kind of configurations, finishes and sizes to suit all interior design schemes.

If you have opted for a more classic kitchen style, such as a Shaker kitchen or farmhouse, a chunky column radiator will suit it down to the ground. Here, the Stock Anocona, from The Radiator Company, in Graphex, sits beautifully alongside the smoky blue Shaker kitchen. 

5. Save space with a vertical design

Vertical radiators make perfect sense in kitchens where wall space is often largely given over to kitchen units and worktops. Their tall, narrow design slots easily into awkward spots that might otherwise be wasted — plus they are now available in some really eye-catching designs. They are a great option for those looking for galley kitchen ideas too. 

The Milano Aruba Ardus Anthracite Dry Heat Vertical Electric Designer Radiator, from BestHeating, is simple to use and made from lightweight aluminium.

6. Match your radiator to your walls

To ensure your new radiator blends in seamlessly with the rest of your kitchen design scheme, consider opting for a model in a colour that matches your walls — a nifty trick that can also make a space appear bigger. 

If you can't find a design in a colour to suit, you could always familiarise yourself with how to paint a radiator before selecting a shade that will work. 

Here, the The Radiator Company's Ledbury cast iron radiator has been colour coordinated with the walls which are painted in Benjamin Moore's Van Deusen Blue.

7. Take a twist on the traditional column design

There is no reason why a column radiator needs to be traditional in its design — as the Athens Triple Column Radiator, shown here in Dove Grey, from Bathroom Mountain proves. 

While the reassuringly chunky appearance of column radiators is beautiful, it is not always practical in a room such as the kitchen, where every inch of space counts. For this reason, vertical column radiators make a lot of sense — plus they can really enhance a high ceiling. 

8. Combine heating with seating

Consider installing a radiator bench in the kitchen to provide a snug spot to hunker down when the temperature drops. Positioning a radiator bench under a window is a nice idea, allowing you to view the chilly outdoors from a warm seat — but this is an idea that could work anywhere in the kitchen layout. 

The Ancona Bench Seat from The Radiator Company features a subtle pale wooden bench above a sturdy column-style radiator and would also work well in utility rooms or boot rooms, as well being one to bear in mind if you are coming up with a new hallway design. 

9. Use your radiator for accent lighting

Had you considered combining your kitchen lighting ideas with your plans for your kitchen heating? If not, then perhaps this next tip might be a good starting point. 

Radiators now come in all shapes and sizes and there are even models out there featuring illumination — such as this, the Crocco electric radiator from Viadurini which can be customised with a chromotherapy set with remote-controlled speed and brightness. This radiator is perfect once the sun goes down and you want to conjure up a cosy, warm ambience. 

10. Give towels a place to hang

Very often these days, kitchen radiators and towel warmers are almost interchangeable. Although bathroom radiators tend to be bigger and feature more hanging space to accommodate bath sheets and the like, the principle reamins the same. 

The Linton Towel Rail from The Radiator Company would be ideal for those after small kitchen ideas, offering vintage style in sizes as compact as 490mm in width.

11. Reflect light with a mirrored finish

Mirrors can be used in a multitude of ways in order to make small spaces feel bigger than they really are. Placing mirrors near windows really maximises the natural light already coming in, not to mention the views, while using full-height mirrors can create a strong design statement. 

If you don't have space for a large mirror as well as a radiator then consider combining the two instead. The Faro Chrome Single Flat Panel Vertical Radiator from Bathroom Mountain is super reflective. 

Do radiator reflectors work? Rising energy prices and the high cost of living right now have us all looking for energy saving tips and ways to slash our household bills without sacrificing comfort — so could a radiator reflector be one method to add to the list?

Anything that makes our homes warmer without the need to crank up the thermostat is most welcome for anyone at the moment, particularly as the nights begin to draw in.

Radiators remain one of the most popular ways to heat a home and here, we take a look at one common method of maximising the efficiency of them — radiator reflectors. We explain what they are, how they are fitted and just how much money and energy they are likely to save you.

What are radiator reflectors?

Radiator reflectors are, quite simply, a sheet of reflective material that is placed between the back of a radiator and the wall. Usually they are made of metal (commonly aluminium) or a foil-wrapped slimline board. They can be used with most types of radiators. 

How do radiator reflectors work?

To understand how radiator reflectors work, it is useful to consider that your radiators radiate, or give out, heat both into your room as well as into the wall that they are fitted to. 

Obviously you very much want the heat they give off into the room, but you need to do all you can to minimise any heat loss through the wall behind — which will be more of an issue with external walls (particularly those that are uninsulated) than it will with internal, partition walls. 

The purpose of radiator reflectors is to reflect any heat that would otherwise be lost through the wall back into the room. This should increase the efficiency of your radiators — something you will no doubt be keen to do if you have gone to the effort of insulating a wall in the first place.

They tend to be most effective when used on walls in the most exposed areas of the home — namely exterior walls. Internal walls and even party walls will not benefit as much as less heat is lost through these. 

How much money can radiator reflectors save you?

First off, how much do radiator reflectors cost? They vary in price (and quality) but to give you an idea, radiator reflectors from Radflek start from £21.99 for a pack of 3 sheets measuring 1200mm x 600mm, two strips of Radstik and 12 fixing clips.

The money you save will obviously depend on the size of your house, how many radiators you have and how much you use them, the thickness of your walls (solid walls, for example, can be far more prone to heat loss) and your current insulation levels, as well as the type of fuel you rely on to heat your home. It will also depend on the product you choose. 

The energy saving claims from companies vary, but Radflek, whose products have been tested by the British Board of Agrément (BBA) and verified by the BRE, say their products can reduce heat transfer through walls by 45%.

The findings go on to state that in a house built before 1976, with cavity walls, using their radiator reflectors could save £2.75 per radiator, per year. 

Of course, it is important to remember that these kind of energy-saving measures will benefit from being used in conjunction with other steps to improve the efficiency of your radiators. Learn how to bleed a radiator to keep them working efficiently and invest in a thermostatic radiator valve too. 

"Radiator reflectors only really work well when radiators are really hot and the wall behind is cold," explains David Hilton, a renewables and ventilation installer, with over 35 years experience. 

"As we move towards lower flow temperatures in our central heating systems (Building Regs now require a maximum 55°C flow as against older homes with a 65°C flow) and our homes are more insulated, these reflectors are less useful. Spend the money on insulation and draught proofing."

“Radiator reflectors would be just one of the options that people should consider in order to improve the heat retention of a room, says Nick Duggan, Director at The Radiator Centre. "Some other methods might have a greater impact, such as chimney cushions (20% of heat can disappear up an open chimney), draught excluders around doors and windows, and rugs over [uninsulated] wooden floors.”

How do you fit radiator reflectors?

Although every manufacturer will have their own set of installation instructions – which are usually very simple to follow – in many cases you will simply need to measure your radiator, cut the reflector to fit before fixing it between the radiator and the wall. 

Some products come with clips that are fixed to the brackets that attach the radiator to the wall. The reflector then hangs from these clips. In other cases, double sided adhesive tape or sticky pads are used to attached the sheets to the wall.

Can you use kitchen foil as a radiator reflector?

Although this is undoubtedly a cheap idea, it is not necessarily going to give the best results. 

Standard kitchen foil has a tendency to crinkle up, tear and be awkward to work with. While it may well work in the short term – providing you can get it to sit flat behind the radiator – it is unlikely to last as long or perform as well as products that are made specifically for this purpose.

You’ll want to know how to fix a leaky radiator if your central heating suddenly springs a leak. 

If you don't stop the leak as soon as possible you could cause serious water damage to the floor, damaging flooring or carpets. If the leaky radiator is upstairs, the water may also leak through a ceiling or even worse – into an electrical outlet. Plus, if you can’t fix it quickly you might have to go without water for a while and pay an expensive call out charge.

Small leaks are easiest to fix, it might be that you have been trying to work out how to bleed a radiator and when finished you didn’t tighten the valve enough. It could even be as simple as tightening a nut. But if not you need to get on the case quickly to stop the problem becoming worse.

Here we give you the lowdown on how to identify a leak, how to fix it and how much a professional will cost.

How to fix a leaky radiator: Identifying the problem 

Before you locate the problem you need to stop as much water as possible leaking onto the floor. Mop up the water, lay down a few towels and put a container under the leak. 

If the leak is coming from the radiator this should be easy to spot. Wipe dry the radiator and look for water dripping onto the floor. Now look up in a vertical line from the drip to locate the leak.

If it is the valve or pipes first dry the valves and pipes with a towel. Now place toilet roll in different positions and areas around the valves and pipes to locate the leak. First try the valve to radiator join and then the valve to water pipe join. Finally try the top of the valve. 

How to deal with a leaky radiator body 

If the leak is coming from the body of the radiator this is due to corrosion. This indicates that the radiator has rusted from the inside and it's pumping rust around your heating system. This isn’t good for your heating system and means it’s time to invest in a new radiator as soon as possible.

You can invest in a like for like radiator or use this opportunity to buy one of the best designer radiators that you have had your eye on for a while.  

How to fix a leaking radiator valve 

A simple quick fix is to tighten all the nuts on a radiator valve. This may not solve the issue, but if it does, it will be a quick and simple solution that will take no time at all.

Get a suitable spanner and gently tighten the union nuts. These are nuts that connect to the pipe that brings in the water and attach to the radiator. If this stops the leak, it’s job done. If not, it's time for the next step.

1. Stop water flow
Make sure the lockshield valve is closed. This sits on the top of the valve, typically under a plastic cap. Typically it will be fully open. Get a small spanner or pair of pliers and turn clockwise to fully close the valve.

2. Drain the radiator
Now undo the union nut – the nut that connects to the radiator. Make sure to have towels and a container to collect the water. Use a large container, if you don't have one, use two smaller containers to catch the water.

3. Add PTFE tape
Wrap the valve that goes into the radiator with PFTE tape, typically ten turns should be enough. Now do up the union nut to connect the valve back to the radiator. If the leak is coming from the part of the valve that connects to the water pipe, undo this and put PFTE tape on this thread and do up the nut.    

4. Refill the radiator
Now open the lockshield valve to let water back into the radiator. To refill the radiator you will need open the bleed valve – located on the left or right at the top with a radiator valve key. As soon as water starts to come out of the bleed valve, close it. Now check if your repairs have stopped the leak. If not it may be time to replace the valve.  

How do I fix a leaking thermostatic valve? 

A thermostatic radiator valve (TRV) is similar to a manual radiator valve but has a few more parts where a leak may occur. If the valve is leaking from the radiator or water pipe then turn off (down to zero) and follow the steps as mentioned previously.

If this isn’t the cause and the TRV is leaking from within the valve the easy option is to buy a new valve and replace it. You can get these for as little as £10. Alternatively, you can buy spare parts and replace, but this is best done by a professional.  

How much does it cost to fix a leaking radiator?  

If it's only a leaking radiator valve then it won’t cost much more than an hourly rate. There may be a minimum charge - typically around £50 for a simple job. If the valve needs to be replaced expect to add another £30. If you have more than one valve to replace expect to pay at least £50 per new radiator valve.

If you need to call out a plumber in an emergency (typically out of hours) you can expect to pay at least £150. If they are there longer than an hour you will have to pay an hourly rate that will be at least double their standard hourly rate.

If the radiator is the problem it will cost more to fix. To remove and replace your old radiator expect to pay in the region of £150. If you are replacing a larger or double panel radiator expect to pay at least £200.

If you are replacing a corroded radiator you will probably need to have your heating system flushed to get rid of rust flakes. Prices will start at around £300 and rise depending on how many radiators you have.

If replacing a radiator (see our guide on how to replace a radiator) and are looking to  move it to a different location it could be a good time to think about the cost to move a radiator or how to add a radiator.  

Meanwhile, check out our other guides if you have other problems like a radiator not heating up, how to balance a radiator or want to know why else your radiator is not working.

Are your radiators looking a little sorry for themselves, or are you simply tired of white and want to add a touch of flair to your home? Painting a radiator is a quick, easy, and affordable way to breathe new life into radiators. It’s a task that any enthusiastic DIYer can handle.

It doesn’t matter what type of radiator you have; the process remains the same, although some are easier to paint than others. Proper preparation and careful paint selection are crucial for a stunning transformation. In this guide, you’ll find everything you need to know to achieve it.

Choosing the right radiator paint

The first step in painting a radiator is choosing the right paint. Mark Irving, building and decorating specialist at Build & Plumb, says, "The best paint options to use to withstand heat are either radiator-specific paints or heat-resistant paints."

He adds, "These paints are specifically designed so that they will not discolour, blister or emit fumes when the radiator is hot. Low VOC paints can also be used to paint radiators, as they are specifically formulated to resist heat."

Choosing a specialist radiator paint like Hammerite Radiator Enamel Paint is the obvious choice, but it has its limits. It's great if you're just refreshing your white radiators, but it lacks other colour choices.

If you don't want a white radiator paint or are unsure what what to buy we can help you out with our best radiator paint guide. This offers brush and spray paint options for a factory-like finish, along with a wider range of colours to choose from.

The tools you'll need to paint a radiator

Once you have your ready, you can begin assembling your tools, which should include:

• Sandpaper
• Dust sheets
• Primer
• Radiator paint
• Paintbrushes - like this Harris Trade Paint Brush Multi-Pack from Amazon
• Cloth/sponge/bowl

4 steps to paint a radiator

1. Switch off radiator and prep area

Before you start the first thing you need to do is switch off the radiator completely and wait until it is stone cold. This applies to whatever type of radiator you have in your home.

Do this the night before you want to paint. Then on the next day, clear the area around the radiator, vacuum, and put down dust sheets.

You can remove the radiator from the wall if you're going to paint the back and front, but this involves more work. If you are not comfortable removing a radiator, then leaving it on the wall and knowing how to paint behind a radiator is the easier option, and you can still get a great finish.

2. Clean and rub down the radiator

Before painting a radiator, you will need to remove any loose paint, give it a clean and a rub down. If your radiator has a lot of loose paint, then get a wire brush (like this PFERD Hand Brush from Amazon) to remove it.

Next its time for a clean. Irving says, “Radiators are known for collecting hidden dust and grease, so ensuring that you do a thorough clean beforehand is essential.” He adds, “Always vacuum between the fins and along the back using a narrow attachment."

Alternatively, if you have a trend-setting traditional radiator, you can use a microfibre hand duster to get into the spaces between the columns.

To clean, Irving says, “Use a mild detergent solution, or sugar soap, remove any grease and grime on or behind the radiator, then wipe down the surface with a clean cloth and allow it to dry fully.” You’ll need to do a thorough job to get the best finish.

Finally, rub down the radiator, continues Irving, “I would strongly recommend sanding your radiator, as a light sand can remove any existing paint and ensure that the new paint adheres properly. He adds, “If there are any areas of rust, I would recommend sanding them back to their bare metal before applying a suitable metal primer.”

3. Prime the radiator ready for painting

The first coat to be applied to the radiator is a primer — especially if you are using a paint that isn’t a specialist radiator paint. ZINSSER B-I-N Primer Sealer is a good choice.

A primer will ensure a long-lasting paint job and better finish.

4. Paint the radiator from top to bottom

Using a brush or spray can are your best choices for application. You can use a roller if you have a flat panel radiator, but these don’t produce the best finish on most radiators.

The easy option – and most commonly used – is a paintbrush. Use a 2-4 inch brush for the main part, but have a ½ inch brush on hand for difficult to get into areas.

If you're painting a single panel radiator, start in the top left or top right corner and work down in strips. Don’t overload the brush with paint. When you're finished, lightly brush over any areas that need blending, and make sure you have no runs.

Double panel radiators are one of the best radiators for style and efficiency and you start by painting the ends first. Then paint the front before leaving to dry. Be sure to check the manufacturer's instructions for information on drying times.

Next, apply the topcoat the same way and leave it to dry. Make a judgement call if you need another coat or not.

FAQs

Why are radiators painted white?

White reflects heat rather than absorbs it. This means it will better project heat from a radiator into a room. In reality, there is little difference between white and a darker colour.

The type of paint has more bearing, explains Jimmy Englezos, Senior Brand Manager at Ronseal: “A radiator’s heat output is actually more manipulated by the reflectiveness of its paint finish.”

He adds, “Shiny surfaces such as chrome or stainless steel will reduce its overall heat output since the shinier surface reduces its ability to transfer heat to the surrounding air.”

The alternative option is a matt finish, continues Englezos. “Matt finishes can improve a radiator's efficiency and heat output,” He adds. “With black being the most efficient colour choice since it absorbs all light wavelengths before converting them into other forms of energy, in this case, heat.” But again, the difference is nominal.

On the plus side, white paint is typically cheaper than coloured paints and provides a good base if you want to paint a radiator another colour. It is also a neutral colour that will work well with most other wall colours.

How do I spray paint a radiator?

Spray cans are the easy option to spray a radiator and will produce a smooth professional finish when done right. One can will provide a couple of coats on a small radiator.

To do this, you will need to prepare the area thoroughly as spray can spread easily. Cover the walls around two feet all around the radiator with newspaper or plastic sheets, and put dust sheets on the floor and over any nearby furniture.

Shake the can as instructed to mix the paint, then apply light, even coats from a distance of around six inches. Make sure you keep the can moving — if you concentrate on one area you will get runs. Let the first coat dry and add a second, and a third coat if needed.

It's a good idea to keep the room well ventilated whilst using a spray can too.

Can I use gloss paint on radiators?

Yes, you can, but make sure you use a gloss paint suitable for radiators. Most quality gloss paints can withstand the heat output of a radiator. You might want to avoid oil-based paints as these are prone to yellowing when exposed to heat. This is especially noticeable on white radiators.

A suitable paint with a satin finish is a good alternative. It provides a great-looking finish and is more subtle, with a lower sheen.

How soon can you turn on a radiator after painting?

Once you have applied the final coat of paint to the radiator, leave it for at least 24 hours before switching back on. If you can, leave it for 48 hours in total. This will make sure that the paint is completely dry and ready to take the heat.

If you removed your radiator to paint it you will need to fix back on the wall and reconnect to the central heating system. To make sure that your radiator is getting back up to its maximum temperature you will need to know how to bleed a radiator. It's pretty straightforward but essential.

Before you start painting a radiators you should check out our living room radiator ideas, bedroom radiator ideas and hallway radiator ideas to ensure you can find the best look for your home.

It's not unusual to encounter the issue of a radiator not heating up once your central heating is in full flow again. But, if the heating is on, it's clearly not a problem you can leave for long.

Fortunately, many of the solutions don't always need a professional and there are plenty of DIY fixes you can tackle yourselves. But, what are the reasons why your radiators aren't heating up, and when do you need to call in a professional to fix them?

In this guide we'll explore the most common causes why your radiators aren't working, and outline the solutions to make your home toasty warm once more.

Why is my radiator not heating up?

In general, the reason why your radiator is not heating up properly comes down to the following:

• Debris in the pipework or filter
• Circulation pump not working or has air in it
• Air in the system
• Thermostatic radiator valve (TRV) is stuck
• Lockshield has been fully opened or closed
• Boiler or heat pump not working properly
• Central heating has turned off
• Fuel source has run out

While some are more serious than others, your first action should always be to check the basics. Is your central heating on? Is it on the right setting?

Yes it sounds obvious, but before you do any of the above, you really should check that your central heating hasn't been switched off or set to summer mode, or to heat the water only, by accident – you really don't want to go calling out a plumber only to discover this was the cause.

Another embarrassing cause of radiators not heating up (a bit like running out of petrol) is because you have run out of fuel. If you are using LPG or an alternative heat source such as a biomass boiler, make sure you have enough fuel to heat your home.

Or, perhaps it's something as simple as the pilot light on your boiler going out.

Once you've checked your heating system is in good order, it's then time to look at the individual reasons why a radiator is not heating up properly and see if you can fix it yourself.

1. A blocked radiator

"If the system has not been serviced then there could be a build up of debris in the pipework or the filter," explains renewables expert, David Hilton. The simple solution is to get the system serviced by a professional.

Blocked radiators can be caused by a build up of limescale, sludge, rust or debris flowing through the system. This restricts the flow of water meaning blockages that start of fairly small can quite quickly become big blockages.

Blocked radiators are usually cold at the bottom and warm at the top.

If the problem is only affecting one radiator, it can be possible to remove it and flush it out with a garden hose, before replacing it. However, if you have several radiators not heating up then it may be necessary to have them power flushed by a professional.

A power flush uses pressure to shoot water and chemicals through the system, removing dirt and flushing it away down an outside drain.

2. Circulation pump not working

If a few, or all, of your radiators are not heating up, the circulation pump could be to blame.

Circulating pumps move hot water around a heating system, taking it from the boiler through the pipes to your radiators and hot water cylinder in some cases – before taking it back to the boiler.

Sometimes, blockages or airlocks in the system will occur. Good indicators that this may have happened, other than radiators not heating up, include a water leak from the pump, unusual noises coming from the pump, casing that is hot to touch and no hot water.

You will need to call in a plumber to fix the problem.

3. Air in heating system

A very common cause of radiators not heating up is an airlock in the central heating system.

"There could be air in the system which would mean that the radiator may only heat a little bit at the bottom, or not at all if there is a lot of air," explains David Hilton. "You will need to bleed the radiator to get the air out.

"As you let air out of the system you need to allow more water in. A gravity fed central heating circuit should fill automatically but a high pressure system will have a valve (or two) to let the water in. Don’t leave this valve open," says David.

"Pressurise the system a bit and then bleed the radiator. It is usually best if two people do this but if in doubt call in a professional."

4. A stuck TRV

If it is just one radiator not heating up, then a stuck thermostatic radiator valve could be the culprit.

A thermostatic radiator valve controls the flow of hot water to a radiator and occasionally these can get stuck, meaning they can't open to allow the hot water in.

"The TRV pushes a pin in and out and sometimes this pin corrodes and will not move," says David Hilton. "By unclipping the TRV you may be able to free it up, but be careful as it may be badly corroded and pop out or leak."

Try to free the pin using pliers and grease but don't use excessive force as you might damage the pin. If you can't free the pin then we would advise you call a professional.

5. Lockshield in wrong position

"On the opposite side of the radiator to the TRV is a lockshield," says David Hilton. "This looks like a small valve with a cap on it and it is used to balance radiators. What can often happen is that this is closed when a radiator is moved (for example, to paint behind a radiator) but then fully opened again when the radiator is replaced, rather than returning it to its previous position, which is often only a quarter turn open.

"This means that the boiler water will now circulate more through the closed radiators and hardly ever get heat to furthest away radiators."

A good signal that this is your problem will be if the radiators upstairs (or those nearest to the boiler) are getting hot, but the downstairs radiators are cold. The system will need to be rebalanced.

6. Faulty boiler or heat pump

An obvious reason for radiators not working is a faulty boiler or heat pump. Check your boiler is on the right setting and appears to be working – a fault code will usually alert you to a problem. You may find you can put it right easily, but in some cases a Gas Safe registered heating engineer will need to be called out.

If you use a heat pump to heat your radiators, check it is working as normal and that it hasn't become clogged with any debris. In some instances, you may need a new boiler. Check out our how much is a new boiler guide for more info.

7. Drop in water pressure

If you have a combi boiler, or a high-pressure central heating system, the problem could lie with a drop in pressure, causing the boiler to cut out.

Take a look at the pressure dial – it should be in the range specified in the instruction manual. If not, you will need to top-up the water (check your manual for instructions) to repressurise the boiler.

FAQs

Why is my radiator still not working after bleeding it?

"If your radiators are still cold after bleeding, it’s a sign the issue isn’t trapped air but something deeper," says John John Klee, heating technology expert at Best Heating.

"This could be something like a stuck thermostatic valve, low boiler pressure, or a blockage in the system. Bleeding only releases air, so persistent cold spots often mean the system needs balancing or a professional power flush to restore proper water flow and heat distribution.”

How can I prevent my radiators from not heating up properly?

The first thing to do is get a service in the summer months, to make sure everything is working as it should ready for the winter months. You can also run the heating system every now and then, maybe once a month or every other week, leading up to winter to make sure it is working well.

You can also check the pressure on the boiler, especially in the autumn - you are looking for the pressure to be just above 1 bar up to 1.5 bar.

Some of this you can do yourself, such as checking your system during the summer months; for a service you’ll need to call in a professional.

Although some of these problems can be fixed, if your radiator is leaking water from the bottom, as well as not heating up properly, it might be time to replace it. Check out our how to remove a radiator guide for advice on how to do this, and take a look at some of the best radiators you could replace it with.

Thinking about moving a radiator? It's a common option when planning a home update. Whether you're decorating, knocking down a wall, or remodelling a space, there’s a good chance you’ll need to reposition a radiator – perhaps to a new spot on the same wall or even to a completely different room.

Moving a radiator is also the perfect opportunity to upgrade to one of the best radiators on the market and make a design statement.

However, you’ll need a professional’s assistance to make it happen. Here, we explore various scenarios for moving radiators and what you can expect to pay for each.

Factors that affect moving a radiator costs

The cost to move a radiator will vary depending several factors, including:

• The type of radiator you are moving
• The new position
• Existing pipework
• The radiator size
• The nature and complexity of the job, including the construction of the walls and floors

"It may seem like a simple task, but moving a radiator can have some hidden complications," explains heating expert and regular Homebuilding and Renovating speaker David Hilton.

"The first thing that is required is to ‘map’ the existing pipework to be sure that it can be easily rerouted to the new position, and also a health check to be sure there is no corrosion or bacterial growth due to a lack of servicing and chemical inhibitors.

He adds, "Radiators are usually plumbed in parallel and as such the plumbing must maintain this configuration. A simple move could cost around £80 to £200 for materials, but if there is a lot of wall chasing and rerouting of pipework, plus a potential power flush to clean the whole system, and then a rebalance, then the cost could easily reach the thousands."

"Get a few quotes and plan the work for summer when the engineers are less busy, and you also do not need the central heating," concludes David.

Cost to move a radiator to another wall

If you’re remodelling the layout of your home and knocking down internal walls to create a more open plan layout, there’s a good chance that you’ll need to move a radiator to another wall.

"Or, perhaps you are replacing one that is a bit old and rusty, or moving one to another part of your home for better heat circulation," says Mike Flook, plumbing expert at MyBuilder.com. "But, before hiring a qualified plumber to complete any of these jobs, there are a number of things you must take into consideration," he says.

"Firstly if your pipework is suitable enough to allow you to move your radiator from one location to another. Prices will be higher if your radiator is being added to somewhere that needs new pipework, and this will likely cost at least £400.

"If this issue is unavoidable, and you also need a new radiator, removing and replacing an old one costs around £150 - £300, the price again depending on the size of your radiator, or any issues that occur when doing this job, such as spills or heating system malfunctions."

However, if you don't require new pipework, "this can be expected to cost between £120 and £180, owing to the materials needed, and the labour costs to move the radiator. You may, however, be expected to pay a higher fee if there is existing corrosion or bacterial growth, or if the radiator is particularly large," adds Mike. 

Try these radiators when you upgrade

Cost to add a radiator

If you decide to buy a new radiator, as opposed to simply moving an existing radiator from one spot to another, you will also need to factor in the cost of buying this new model.

A small single-panel radiator can cost as little as £30, with prices rising to around between £80 and £150 for larger radiators with higher heat outputs. Designer radiators and cast iron models will cost considerably more, with prices easily surpassing £200.

"Adding another radiator will likely cost at least £150, not including materials, and may amount to even more depending on the size and type of the radiator," confirms Mike Flook.

Cost to move an electric radiator

Moving an electric radiator is usually a far simpler job than moving a central heating radiator.

Most electric radiators are just plugged into a power socket, meaning that they can be taken off the wall and fixed to the new wall before being plugged into another socket.

However, things get a little more complicated if the radiator is hardwired into the wall – in this case, you should call in a qualified electrician, who is likely to charge you around £40 per hour to carry out this job.

Cost to remove a radiator

To simply remove a radiator, a plumber will typically close the valves at both ends, drain the water from the radiator (rather than the entire system) and then remove it from the wall and cap off the pipework.

The job is relatively easy and shouldn’t take long, although as with all radiator jobs will depend on the final amount of work needed. Expect to pay anything from around £80 - £140 & VAT.

To save money, many people who are confident in their DIY skills choose to do this job themselves.

Cost to drop a radiator

You may have heard the term 'dropping' a radiator. All this refers to is temporarily moving a radiator off the wall before putting it back in the same position – something that is commonly done when painting behind a radiator.

There is usually no need to call in the professionals for this job, although, depending on the weight of the radiator, you might need someone to help you lower it to the floor.

You will first need to isolate the radiator in question from the rest of the central heating system before draining the water from it. (Ensure you protect floor finishes below, such as carpet and wood flooring, whilst completing this task.) Once you are sure all the water is out, you can lift the radiator off its brackets and place it out of the way while you paint.

Once the paint is dry, the radiator can be reattached to its brackets and reconnected to the valves and pipework before refilling the system.

A plumber is likely to charge you around £100 – £125 for the job of dropping and replacing a radiator.

Extra costs to consider when moving a radiator

Labour and material costs aside, there are several other factors that can come in to play when calculating how much to move a radiator.

• You may need to fill holes and make good any damage to the wall the radiator is being moved from
• If the wall you are moving the radiator to is an existing stud wall, extra timber battens may be required as reinforcement before attaching the radiator. Again this wall will need to be 'made good' following this task
• Holes in the floor where the radiator was located previously will need to be filled
• Don't forget to factor in the cost of a new radiator if you plan on buying a one rather than reusing the old one
• In order to finish the job off nicely, consider covering radiator pipes and factor this into your overall costs.

Before moving a radiator check where heat loss in a house happens to choose efficient placement. To enhance new radiators you can add a little style and panache with some smart radiator shelf ideas and radiator cover ideas.

When you need a new radiator, there’s plenty to choose from – from the less thrilling type of radiator through to the inspiring choice of style and colour to match your interior design dreams.

But before you dive in and choose a radiator, you need to know what will work well for your home. Will your chosen radiator output be enough heat to keep a room warm and toasty? Will it add style and charm? Is it the best option for your home?

In this guide, those in the know offer up their advice to help you make the right choice for you and your home.

Radiator heating options

Before you get stuck in to selecting a type of radiator, take some time to consider how your radiators will be heated. There are three main options:

1. Plumbed radiators

This is the most common type of radiator. It will be connected to your central heating system and rely on your boiler to heat hot water which will then be circulated through pipes around your home into the radiators.

2. Electric radiators

These are a good option for those looking for a radiator to fit into a space where there is no central heating – for example a new garden office, or annexe. Rather than being controlled centrally, electric radiators are operated individually. Some can be plugged into to a conventional socket, while others need an electrician to fit.

3. Dual fuel radiators

This radiator type is usually a central heating radiator that has a mains-powered device inserted into it. This allows you to have the radiator heated even when the central heating elsewhere in the house is turned off (for example in the summer months) – it is a great option for heated towel rails.

Try these radiators to heat your home

Types of radiator

There are several different types of radiator – they vary in size, shape, style and also in how much heat they emit.

Single panel radiators

These are the most basic of all the types of radiator out there. These horizontal radiators run off the central heating and are wall-mounted.

Nick Duggan, Director at The Radiator Centre, shares why they are good for, “One of the biggest advantages of choosing a single panel radiator is its sleek simplicity.” He adds, “Its slim profile makes it an ideal choice for spaces where you want to maximise floor space or maintain a clean, uncluttered look. Single panel radiators are typically used in hallways, smaller rooms or modern open-plan areas where understated style and efficient heating go hand in hand.”

However, it is worth noting that they give out less heat than double or triple-panel models.

Double panel radiators

Double-panel radiators are horizontal-style radiators, made up of two single panels up against each other. They are also wall-mounted.

“Double panel radiators offer exceptional heat output,” shares Duggan. “With two layers of panels working together, it warms a room quickly and efficiently, making it ideal for larger living areas, kitchens or rooms with higher ceilings.”

However, do bear in mind that their greater heat output means they can be smaller in width than a single model. It’s also possible to buy triple-panel radiators.

Column radiators

Column radiators are popular with those after a type of radiator for a period home and are a great way to add some character and charm – although its worth noting that there are contemporary column-style radiators on offer these days.

Shamila Iqbal – Director at Bathroom Mountain extols their flexibility, “Column radiators are especially versatile. They come in single, double, or triple column designs, with more columns providing greater heat output.”

They offer great heat output and hold heat well too. In terms of size, they will take up more space than a slimline single-panel model, but they are available with different numbers of columns and even as narrow vertical radiators

Iqbal shares where they work well, “A single column radiator is slim and works well in narrower spaces, while double and triple column models deliver much more warmth, making them perfect for bigger rooms or homes with high ceilings.”

She adds, “An additional benefit of column radiators is the variety of sizes available, including very tall but narrow options. These vertical designs offer a great space-saving solution where wall width is limited but the ceiling height can be used, making them ideal for compact hallways, cloakrooms, and alcoves.”

Vertical radiators

Vertical radiators are also sometimes known as 'upright radiators' and are ideal in smaller spaces or where a more creative solution to the more traditional style of radiator is required. They make a great design statement.

They are tall and narrow and perfect for thin wall spaces, freeing up wall space elsewhere. They come in all kinds of designs, from column-style to flush and contemporary and some even have little pegs attached for hanging tea towels and the like in kitchens.

Heated towel rails

Heated towel rails – or ladder rails as they are sometimes referred to – are radiators that are designed with drying and heating towels in mind, making them the best bathroom radiators. However, they will also give off useful heat into a room so are one of the best ways of heating a bathroom.

Heated towel rails can either run off the central heating, along with the rest of your radiators, or you might prefer to opt for an electric towel warmer instead.

Electric towel rails are useful in that they can still be warm even in summer when your central heating is switched off.

An alternative to both of these options is to go for a dual fuel towel rail which can run off the central heating system when it is on, or use the mains electric when it is off.

When it comes to choosing a heated towel rail, do try to go for the biggest you can – particularly in family bathrooms where there is likely to be numerous wet towels to hang.

Designer radiators

Some radiators look like works of art rather than practical fittings that will heat the home. Designs come in all shapes and sizes from mirrored vertical radiators to those that look like waves.

While designer radiators can become a real focal point in the home, do remember to double check that their heat output will heat your room adequately.

FAQs

What size radiator do I need?

In order to work out what size radiator you need in a room, you will first need to calculate the required heat output of the space, which will be measured in BTUs (British Thermal Units).

This calculation will take into account the size of the room and what type of glazing you have. There are numerous online BTU calculators available for use, and all you need to do is know the room's measurements in cubic feet.

Do bear in mind that it is unlikely that any radiator will match the exact heat output required, so just select the first size above the required heat.

Also, in rooms that are larger than 6m in any direction, it is a good idea to consider more than one radiator in order to get a good distribution of heat.

Do larger rooms need more than one radiator?

Larger spaces do need more heat than smaller spaces, as Nicholas Auckland, Managing Director of Trade Radiators, reveals, “They often do, but again it depends on the room's overall BTU requirements. If it's particularly high, spreading the heat across two or more radiators can be more effective than using one oversized radiator.”

He adds, “This is because it'll help distribute heat evenly, preventing any particularly cold spots in your room. Placing at opposite ends of the room is recommended in order to prevent uneven heat distribution".

New radiators are a great way to update a space, but if your budget won’t currently stretch to an update, painting a radiator is a quick and cost-effective way to upgrade. Check out how to paint behind a radiator and the best radiator paint to get the best finish.

Covering radiator pipes will make all the difference to the finish of your radiators. Whether you've spent money on a beautiful new radiator or you're simply trying to give your existing radiator an upgrade, many of the ways you can cover pipework are relatively inexpensive and easy to apply. 

In this quick guide, we offer options for not only covering the vertical valve pipes, but also ideas for tackling pipework which has been run on the surface of a wall, such as along the skirting boards, rather than being incorporated in the wall or floor void. 

When you spend time and money choosing radiators, finishing off with the right details is important, and with these handy products and DIY ideas to hand, you'll be able to create a sleeker finish to any room heated by a radiator. 

1. Use Pipe Sleeves When Installing a Radiator

Radiator pipe sleeves are probably the most elegant and sophisticated way of covering radiator pipes. Pipe collars are largely made from metal and are available in a range of styles and finishes. 

To install, they are simply slipped over the top of the radiator pipes; however, these can only be installed when the valves are not yet attached. If retrofitting, draining the central heating system and removing the valves may be a tedious task in order to install pipe sleeves, but for some, it's a level of attention to detail that's worth the time and expense. 

Your best bet is to install pipe sleeves when installing new valves and/or replacing radiators. It's possible to buy valves that come with matching sleeves, especially when they're a more unusual finish, but you'll also find pipe sleeves available to buy in many popular finishes, including chrome and brass. 

Pipe sleeves also largely come with small collars that are used around the base. These are useful to help hide gaps where flooring has had to be cut around radiator pipes, and can also help reduce draughts. 

2. Try Snap-on Radiator Pipe Covers

If you love the idea of a radiator pipe sleeve for covering your radiator pipes, but don't want to have to remove the valves to install them, then these clever snap-on solutions are for you. 

Snap-on pipe covers are made from a film-like material which simply and easily wraps around a radiator pipe. They're available in a more limited array in general, with colours including chrome, white and dark grey most commonly seen. However, they're surprisingly effective, and the best ones look like metal covers until you're up close. 

It's worth noting that there will be a seam on the back on the pipe which is largely unnoticeable, but the collar will have a larger gap which is required to wrap it around the pipe. Over a prolonged period of time, the heat may also cause the finish to fade, meaning they may need replacing every couple of years or so; however, snap-on radiator pipe covers are inexpensive, so certainly worthwhile in this respect. 

3. Opt for Rebated Skirting Board for Horizontal Pipes

If you do have radiator pipes running along a wall, instead of through the floor or wall void (of which, there may not be one), then there are options for covering radiator pipes in this instance. 

The sleekest choice would be rebated skirting boards, which have a small gap cut into the back of them, wide enough to fit pipes or wire so that they can be run along the wall unseen. 

However, for this to work seamlessly, this would require forethought and planning, and largely would only apply to new plumbing where new skirting board was also being fitted. This makes rebated skirting boards a great product for renovations where completely moving pipes may be too expensive or difficult, but where re-arranging the pipework is possible to fit behind the skirting. 

4. Box in Pipework With Trunking

Trunking is never an ideal solution, whether it's for electrics or for plumbing; however, it's possible to find some decent-looking trunking that can be used to box in radiator pipes horizontally along a wall. 

Trunking is going to look bulkier and wider than traditional skirting, but it might be a more attractive option than exposed radiator pipes. You might even consider facing this trunking with skirting board so that it matches in with the rest of the room. 

5. Consider Painting Radiator Pipes 

The classic unfinish radiator look will see a chrome or white radiator valve with copper piping — not a look that works no matter how industrial or raw you want to go with your interior design scheme. 

Painting radiator pipes is a good quick fix that can help disguise them in your room. You can do this in the same way as painting radiators, and as long as you're using one of the best radiator paints that's heat-resistant, it's a speedy job that will wear well. 

It might seem obvious to paint them to match your valve, but consider painting them the same colour as your skirting instead, as this will help them disappear more. 

6. Use a Radiator Cover 

In the worst case scenario, a radiator cover might be your best option, covering not only your radiator pipes, but your whole radiator too. 

You may be reticent to do so for fear of reducing your radiators efficiency, especially during the colder months, however, there's some evidence to suggest that using a radiator cover the right way, and applying a heat-reflective board behind the radiator, might even help your radiator heat your space quicker. 

Whether you subscribe to that idea or not, a radiator cover is a brilliant way of turning what can be an unsightly element of your home into a focal point, and there's are many different designs and styles you could try, whether off-the-shelf or DIYed.  

If you have central heating you ideally need to know how to bleed a radiator. It is a key skill that any DIYer should have in their arsenal. It will release air trapped in the central heating system and let water fill the radiator getting rid of any cold spots.

Trapped air can be one reason a radiator is not heating up and releasing it will ensure that the radiator runs more efficiently meaning that you will get maximum output. This in turn will make your radiators more cost-effective to run than if they were simply left.

While a lot of areas of plumbing should be left well alone, bleeding a radiator is something that you can take on yourself relatively easily. All you need is a radiator key, a few key items and the know how, which you can find in this guide. 

Just make sure that you do a check before winter rolls around and you will have a central heating system working as efficiently as possible to keep your home warm and toasty.

VIDEO: How to bleed a radiator

How to bleed a radiator: Signs you need to sort

Why do you need to bleed a radiator? Martyn Bridges, Director of External Affairs at boiler and heat pump manufacturer  Worcester Bosch reveals one of the most common reasons: “It is a normal occurrence for air to build up in your radiator over time.” 

But what's the tell-tale sign that you have trapped air in a radiator? “You can usually tell if your radiator needs to be bled as they will be colder at the top than at the bottom.” You’ll find this effect is even more pronounced in vertical radiators and towel rails.

Another sign a radiator needs bleeding is unusual noises such as gurgling, clunking and rattling.

If you’re unsure, there’s no harm in trying to bleed your radiator, as long as you follow the steps carefully as not to de-pressurise your boiler and cause damage to your heating system. 

You may also need to bleed radiators during the process of how to balance radiators, or when draining the central heating system for installing a new boiler or replacing a radiator.  

6 steps to bleed a radiator

1. Prepare to bleed the radiators

To start, make sure that your central heating is off and that the radiators are cold. Bridges warns: "You should not bleed a radiator when it’s hot. It is extremely dangerous as the radiator is filled with hot water and air, which can spray out when the valve is opened." This will apply to any type of radiator.

At this point, you’ll also need to know how to re-pressurise your boiler and find the pressure gauge on the boiler. You’ll need to keep an eye on this during the process, so it’s a good idea to have a second pair of hands to help with this job if possible.

2. Protect the surrounding floors and walls

You will need to protect the wall and floors around the bleed valve. You don't want rusty water over your nice clean walls and floors. Place a towel between the radiator and the wall. Then hold another towel just underneath the bleed valve. 

You shouldn't need it, but make sure that you have a bowl on the floor underneath the bleed valve to protect it from any further drips.

3. Find the bleed valve and release the air

The bleed valve is typically located on the top right hand side of the radiator. But as Bridges points out: "They could be on the left or right hand side". The best traditional radiators, contemporary and modern radiators are typically all the same. 

He adds: "You require either a radiator air vent key or sometimes a screwdriver to open the bleed valve." You’ll need to turn the key anti-clockwise to open the bleed valve.

You will hear air hissing from the valve meaning the air is being released. But make sure you are ready for a squirt of water. As soon as this happens turn the key clockwise to close the bleed valve.

Closing the bleed valve at this point is vital as it avoids 'over-bleeding' the radiator. Turning the valve too far or bleeding a radiator for too long can lead to too much water loss being lost. This in turn may decrease the system’s pressure significantly. 

This is why it's important to check the pressure gauge on your boiler…

4. Keep an eye on the boiler pressure

After bleeding a radiator – keep your bleed key in a save place, they are easy to lose – check you boilers pressure gauge. Often the pressure will drop and fall outside the optimum green band and into the red. 

If the gauge level falls into the red zone, you will need to repressurise your boiler to bring it back into the green zone. This is relatively simple – especially on new boilers – but it will differ from brand to brand.

In the image below the two blue handles are used to repressurise the boiler. The one on the left opens the water supply and the one on the right repressurises the boiler. If unsure on how your filling loop works, check the manual or call in a professional. 

5. Continue to the next radiator

Repeat the above step on your other radiators that need attention. Work from the furthest radiator away to the nearest to the boiler, starting with the ground floor.

If remodeling you may want to know how much it costs to move a radiator. If you do have a radiator repositioned you will need to follow the previous steps once installed. Make sure valves are closed and the radiator is bled to ensure it pumps out plenty of heat. 

6. Turn the heating back on

Once you’ve bled all the radiators you need to, turn the heating back on and check that they’re heating up correctly. If not, there may be another reason for your radiators not working that may require it to be flushed. 

Also, double check all the valves are properly closed and that none of them are leaking.

How to bleed a radiator FAQs

How often should I bleed my radiators?

Ideally radiators should be bled at least once year, and this should be done before heating season starts to ensure they're working as efficiently as possible for when you do finally turn the heating on.

According to Toolstation spokesperson Mark Biles, Operations Director at M & M Mechanical Services: "You should look to bleed your radiator every few weeks in the winter because cold spots can appear at the top of the radiator which is evident of air lock in the radiator. If you don't bleed them then air can travel round the system and cause issues with flow rates and potentially lead to rust over time."

What tools do I need to bleed a radiator?

Bleeding a radiator doesn’t require many tools. The only tool you’ll really need is a radiator key, the design of which may depend on your individual radiator, but generally looks like the wind-up mechanism from an old-fashioned toy or a mini tyre iron-style wrench used for car wheels. 

With that, you’ll also need a couple of towels (they won’t necessarily get dirty, but use old ones anyway) and maybe some shallow receptacles such as bowls to catch any water released while bleeding the radiator. 

How do I bleed a radiator without a key?

If you don’t have a radiator key to hand, no problem. Bleed valves are often slotted, meaning you can just use a flat head screwdriver. If not, it may have an opening for a tool like an Allen key, or you can often open these valves with an adjustable wrench spanner. 

A radiator key gives you the most control, however, and they’re cheap – like this radiator key from Amazon – so it’s worth keeping one or two in your toolbox. 

Do you bleed a radiator with the heating on or off?

Always bleed a radiator with the heating off and after waiting for radiators to cool down. Once you’ve released the air in the radiator, water will start to spray or leak from the bleed valve, so you’ll want to make sure this is cold, not scolding, water. 

How long do you need to bleed a radiator for?

Not long at all. Depending on how much air is trapped in your radiator, you’ll only need to open the valve for between five and 30 seconds. The key is to ensure you do not 'over-bleed' a radiator, as the loss of water can result in the boiler needing to be repressurised.

What order should you bleed radiators in your house?

The general rule for bleeding radiators is to start from the furthest radiator away from the boiler and work your way towards it. If you’re doing radiators across multiple floors, start with the ground floor first, then repeat the process upstairs. 

This may not always be an exact science in large, sprawling houses, but as long as you try to work to this order as much as you can, by and large you shouldn’t encounter any issues. 

If your radiator springs a leak after it has been bled – it shouldn't – check out our how to fix a leaky radiator guide to help identify any problems.

Bleeding a radiator is a simple solution to ensuring radiators are working at their optimum. Bleeding a towel radiator is a slightly different process, and if you want to add a radiator to your heating system you’ll need to bleed a radiator.

The best traditional radiators should really deliver in terms of style, complementing period style interior schemes perfectly without stealing the limelight.

Traditional homes are usually full of gorgeous original features, such as fireplaces and doors, and the last thing you want when choosing radiators is for them to detract from these features or to overwhelm the space.

Traditional radiators, such as column style models, are a great choice for classic interior schemes, offering bags of period charm. Developments in the industry also mean that they no longer all carry the hefty price tag they once did either. 

Here is our round-up of the best traditional radiators, based on heat output, appearance and price.

The Best Traditional Radiators

This is a really simple yet elegant column radiator — perfect for slotting quietly in with pretty much any interior scheme out there.

It has a great heat output and a reasonable price tag. Made from low-carbon steel, the Elegant Traditional Radiator is powder coated three times and treated with an imitation porcelain coating that resists rust and offers a high gloss finish. 

Finally, the style comes in a wide range of sizes and styles, including vertical models to fit in awkward spaces.

Based on a Victorian design, the Neo Classic 4 Column from Arroll features a simple and stylish design that makes it well-suited for both modern and traditional home settings. 

The matt cast iron construction makes this radiator highly efficient - this is because it takes longer to cool down, keeping you warm long after you turn off your central heating. 

It also comes with a standard bleed valve, wall stays, air vent and touch-up paint, and has a 10-year manufacturer's guarantee. 

Buy the Arroll Neo-Classic 4 Column Radiator

This long, low model of column radiator is perfect for those after a design to fit beneath a low window cill. 

Its chunky column design and classic looks mean it would sit effortlessly within a more traditional interior scheme — yet the anthracite finish gives it a contemporary twist.

Bear in mind that it is fairly hefty to carry and its long proportions make it a little awkward to manoeuvre so be sure to enlist a helper when getting it into position. 

Buy the WarmeHaus Traditional Cast Iron Style Double Column Horizontal Radiator

Perfect for smaller spaces, the Milano Windsor Column Radiator is sturdy, attractive and has a really impressive heat output given its compact dimensions — plus it retains heat well even after the heating has gone off. 

Whilst it might be a little more pricey than some similarly-sized steel column radiators, it is high-quality and has an expensive-looking anthracite finish, as well as a very reassuring 20 year guarantee. 

Buy the Milano Windsor Column Radiator Horizontal Cast Iron Style Radiator

Not your average traditional radiator — this one is a real attention grabber. The Terma Rolo-Room Quartz Mocha Horizontal Designer Radiator features straight 'tubes' in place of the more classic columns.

A design benefit is that it features large internal holes which enable quick internal distribution of the water, therefore it heats up very quickly.

The 'Quartz Mocha' finish may be a step too far for some traditionalists but for those aiming to create contemporary interiors within a period renovation project this radiator could be just the ticket.

What are BTUs?

BTU stands for British Thermal Units. The BTU rate of a radiator allows you to know how much heat it will emit. It is a useful way of working out whether or not a particular radiator is the right size for your room. 

You should see a BTU featured on the product spec of any good radiator.

It is important that you choose a radiator or heated towel rail that offers the right heat output for your space so that you don't find it getting too hot or cold. 

Are Traditional Radiators Efficient?

Cast iron and steel radiators generally aren't too different when it comes to heating efficiency, and both provide a similar heat output. 

One advantage of cast iron radiators is that they retain heat very well, meaning you can turn them off once your room is warm enough and still enjoy the heat for hours after. This can help you save on energy costs too.

However, cast iron radiators can also take longer to heat up, meaning you'll need to switch them on earlier for when you want the room to be heated up later in the day.

Vertical radiators have grown in popularity in the last few years, but not only for their designer good looks. Yes, they may offer a much more contemporary look for those tired of the same old radiators, but they also offer a versatile alternative to traditional horizontal radiators which may help you make use of your floorplan better. 

With that in mind, we’re looking at some of the best ways to put modern vertical radiators from Radiator Outlet to use in your home to maximise the potential of the space.  

1. Add Efficient Space Heating in Small Gaps 

When choosing a radiator for your space, you need to ensure that it’s powerful enough to heat the space properly - you can use a BTU calculator to do this. However, where you’ve only got a small area to add in a radiator, such as a hallway for example, you’ll find that vertical radiators allow you to install much more heat output. 

Vertical radiators just offer greater flexibility to your heating mix, meaning that radiators can be used in alcoves, at the side of windows and doors and many more places, without your room being underheated by too small a radiator. 

2. Vertical Radiators are an Effective Choice for a Kitchen

Kitchens are one area that you may benefit most from a vertical radiator. In this space, almost everything is wall hung, limiting the space available for a radiator, especially a horizontal one. Leaving room for a vertical radiator in your kitchen design will ensure that you don’t lose too much space that could have been dedicated to storage and workspace, while picking a designer radiator ensures your kitchen has a modern, stylish heating source.  

3.  Choosing Vertical Radiators Vs Heated Towel Rails 

Vertical radiators are also suitable for using in a bathroom, however, the more traditionally used radiator in this space is a heated towel rail. Which you choose will depend on your needs - a vertical radiator will likely meet your room’s heating requirements more easily, but a towel rail is superior for keeping towels warm and dry. A design like this anthracite towel radiator, which combines the good looks of a modern vertical radiator with the functionality of a towel rail, might be a good compromise.  

4. Pick a Style to Match Any Style of Home  

Vertical radiators come in a greater variety of styles than ever before, so alongside the stylish designer radiators, you can also find traditional column vertical radiators which might suit some period properties better. Radiator Outlet's range is available in double and triple columns, ensuring you can specify the right output for your space. 

5. Choose a Finish to Match Your Interior Design 

The other great thing about the choice of modern vertical radiators is the finishes you can choose. White and Anthracite finishes are some of the most popular, but there are also other creative finishes such as Raw Metal for column radiators and clever mirror radiators that also incorporate a mirror in the design, making a perfect spacesaver for a bathroom, bedroom or even a hallway.  

While underfloor heating was once considered mainly an option for new builds or extensions, developments in product ranges and technology means it's now a viable option for heating your home even when renovating.

And, as well as being efficient and effective – offering a consistent heat throughout a room – it also offers aesthetic advantages such as freeing up wall space without the need for radiators.

However, with a variety of types available, how do you decide which is the best option for your particular project? Based on expert advice from Tim Pullen and those in the industry, we take a thorough look at underfloor heating so you can weigh up the pros, cons and understand which one best suits the needs of you and the construction of your home.

How does underfloor heating work?

Underfloor heating in either of its forms involves running a system of pipes or wires underneath the floor of a room. This effectively transforms the entire floor into one huge heat emitter that warms up the space.

Unlike radiators, which work by heating the air around them through convection, underfloor heating (UFH) uses both convection and radiant heat to warm a space. This combination of heating methods results in a consistent temperature which can be improved further by the addition of a good underfloor heating thermostat and and well-planned zones.

Heating from the ground up, also not only results in better comfort levels, but also puts less of a strain on your boiler when compared to traditional radiator systems. This is because of the lower operating temperature (around 40°C) of underfloor heating – radiator systems usually operate at around 65°C.

In fact, UFH is actually closer to being a ‘radiator’ than a radiator is. It heats the mass of the floor (the screed and the floor finish) and that heat then (mostly) radiates into the room – there is some convection going on but over 80% of heat transfer is by radiation.

It is also useful to note that underfloor heating is great when used in combination with renewable technology, such as heat pumps, which have a low flow rate.

Types of underfloor heating

There are two main types of underfloor heating:

• Wet underfloor heating
• Electric underfloor heating

In basic terms, a wet underfloor heating system features pipes, filled by warm water. Underfloor heating and boilers is one scenario, but underfloor heating with heat pumps is becoming an increasingly popular option. These pipes are typically embedded within a floor screed.

This is the best type of underfloor heating for those building from scratch and/or planning a whole-house system. However, there are also different types of wet underfloor heating depending on the type of floor you have and how it is constructed.

Wet underfloor heating: Your options

Wet underfloor heating comes in two different formats which means that asking how to install underfloor heating will give you two different answers, depending on whether you are building new, or relaying your floor from scratch.

• Buried underfloor heating: This system involves placing the pipes into the floor screed. The floor screed is finished, the pipes buried and the different zones are controlled by the underfloor heating manifold. This is the most efficient wet UFH system, but better suited to extensions and new builds where new floor screeds are required.
• Surface mounted underfloor heating: Also known as low profile systems, ths method involves specialist products that have warm water pipes installed in insulated panels. They are designed to be low profile, adding just 1.5cm to the floor level, making them more suitable for retro-fitting – as long as the increased floor level doesn't impact head space.

Electric underfloor heating: A good option for single rooms or retrofits

Wondering when you might need to consider electric underfloor heating instead? Simon Cook, head of sales at Nu-Heat explains that it generally comes down to the size and space you're looking to heat.

"Electric and wet underfloor heating systems are both great solutions when applied in the right scenarios," he says, "but while wet underfloor heating is an extremely efficient and effective whole house heating solution when paired with a bespoke design, it can require a larger upfront investment to install.

"Electric underfloor heating on the other hand is slightly cheaper to install, but far more costly to run. And, while it has a great response time, electric underfloor heating does lose heat a lot faster than warm water UFH. Therefore, it is best suited to small spaces such as kitchens or bathrooms."

Underfloor heating controls

The majority of underfloor heating system controls feature two main parts:

• A digital zone control that determines the temperature of each room/area
• The underfloor heating manifolds and valves that the zone control operates

The zone control will be placed somewhere where the homeowner can make adjustments, while the underfloor heating manifolds will be placed out of the way – under the stairs or in a cupboard – so as to be unobtrusive.

There is no regular maintenance regime associated with underfloor heating, although knowing how to bleed underfloor heating can help ensure it's working to the best efficiency. If things do go wrong, it will typically be with the heating control systems rather than the system itself. In both electric and wet systems, you'll need to consider the best underfloor heating thermostats to make sure you have the required amount of control over your heating.

It's also important to understand what temperature underfloor heating should be set at to ensure you are getting the best out of your system and managing your energy as wisely as possible.

Pros and cons of underfloor heating

What are the advantages of underfloor heating?

Although underfloor heating is a popular option when self building, it can be harder to decide when it comes to choosing it for a renovation project or extension in a house that already has a radiator led system.

However, the experts say it's a matter that needs serious consideration when you way up radiators vs UFH.

"While most homes in the UK are still reliant on traditional radiator systems, they aren't the best solution for everyone," says Simon Cook. "Of course, a key advantage to radiators is that they are already installed in most homes and so are familiar to most and can be simple to upgrade.

"But, before you decide to stick with radiators though, there are some major drawbacks to consider," he suggests.

"Radiators heat through convection, and as well as this leading to uncomfortable cold spots and draughts, the air circulation can also worsen conditions for allergy sufferers by spreading dust and allergens, all while taking up valuable wall space," says Simon.

"In contrast, although underfloor heating can involve a higher initial investment and may require a slight adjustment period, it offers numerous benefits for health, efficiency, and comfort," he notes.

"Underfloor heating warms the room evenly from the floor up through radiant heat, making it 25% more efficient than radiators and up to 40% more efficient when combined with a heat pump.

"And of course, UFH saves valuable wall space as it is neatly concealed beneath the floor," he adds, "eliminating the design restrictions created by radiators, giving you complete design freedom."

Of course, each decision to install UFH or radiators will be dictated property by property, room by room, depending on heat loss and whether the output from an underfloor heating system is larger than this loss figure.

It's also worth noting that underfloor heating systems have a lifespan of 50 years plus, while the average radiator will only last between 8-12 years before becoming inefficient.

A wet underfloor heating system is estimated to be 25% cheaper to run than radiators when attached to a modern boiler and 40% cheaper when attached to a heat pump. Electric underfloor heating is believed to be around three times more expensive than wet systems however, as electricity is more expensive.

What are the cons of underfloor heating?

Of course there are also downsides of UFH to consider – particularly if you plan to retrofit underfloor heating.

• Underfloor heating is more expensive to install than a comparable radiator system
• Installation time can be longer, especially with wet UFH. Even electric underfloor heating may require work to self level before installation
• When retrofitting underfloor heating, changes to floor height will need to be considered. This may require extra work in digging out the floor for a level profile
• Not all floor coverings will work as well with UFH

Underfloor heating and renovations

In a new build, the extra cost of underfloor heating relative to the whole build cost is seldom a deal breaker.

However, if you're looking to retrofit underfloor heating in a renovation project, it can be disruptive and expensive as it often involves taking up floors that may otherwise be best left alone, or raising the floor level, which may have implications on the joinery (doors, skirting etc).

Low-profile systems tend to have smaller diameter pipes and run at a higher temperature. This means that the floor will heat up and cool down far more quickly than conventional underfloor heating.

Where underfloor heating is added to an existing radiator system then a different control system will be needed. Luckily, wireless underfloor heating thermostats (some of which can be controlled with a phone app) make installation far easier.

It is often a good idea to install electric underfloor heating in a small, single area like a bathroom or en suite, where it may be difficult to install wet underfloor heating.

It is worth noting that one of the most common – and worst – uses for electric underfloor heating is in a conservatory. Typically these areas need a lot of heat and are used for relatively long periods of the day (compared to a bathroom, for example). This means that running costs become an issue and the extra trouble and expense of a wet system may be well worthwhile.

Choosing the best flooring to use with underfloor heating

When it comes to choosing the best flooring for underfloor heating, there are a number of options available – some more suitable than others.

Although underfloor heating with tiles is one of the most popular combinations, there are pros and cons and specific requirements for other options such as UFH with laminate flooring and wooden flooring with underfloor heating.

Likewise, while underfloor heating with carpet can be considered, it won't be as efficient as when used with harder materials such as ceramic and porcelain tiles, luxury vinyl tiles and natural stone flooring.

Concrete is a superb heat conductor, so polished concrete floors also work really well with underfloor heating as the thermal mass of your concrete will retain heat and ensure your room stays warm for longer after your heating is switched off than would be the case with a radiator system. They are easy to pour over the pipework and they absorb and hold the heat produced well. Seek the advice of your installer before switching your underfloor heating on though – too soon and it could crack.

Most retailers will specify whether a flooring will work with underfloor heating, so look for that as your first guide when choosing what you will use to cover the floor.

FAQs

Should I leave underfloor heating on all the time?

Understanding how long does it take underfloor heating to warm up will help guide you towards the best way to run your heating.

With a wet system it can take two or three hours to warm up, so it is better to leave it turned on if you or your family are inside the house and need to keep warm.

To save costs, you can adjust the temperature instead, to make it lower during night time or times when you might not be using the space.

With electric underfloor heating meanwhile, the floor can heat up much quicker. The heating costs depend on how many kilowatts hours (kWh) of electricity you use and this will be more, the longer the heating is turned on or the more watts the underfloor heating uses. For a 125W system turned on for an hour, for example, this will use 1KWh for every eight square metres of electric underfloor heating

How thick should underfloor heating screed be?

The thickness of the floor screed during your installation process will make all the difference. The screed thickness in which the warm wet pipes sit will have a dramatic impact on how the system is used.

A thick screed will give a longer reaction time (the time taken to warm up and cool down), while a thin screed will have a quicker reaction time.

Which is right and best will depend on the construction of the house, your occupation habits and how the underfloor heating system is to be used, however, the following offers some guidance:

• If the pipes are housed in the concrete floor slab, this should be 150mm thick and give a reaction time of over four hours. In this situation, it is best to run the system all day, at a lower room temperature – say 15°C or 16°C – to provide background heating to the whole house. Highlight heating, such as a log burning stove, is a good idea in the rooms that are occupied
• A standard sand and cement screed would typically be 65mm to 75mm thick and the underfloor heating could take upwards of two hours to heat the room or cool down. This situation may be well-suited to rooms where we spend a lot of time, such as lounge or kitchen, but might be less acceptable in a guest bedroom
• With thinner flow screeds, we might expect a thickness of 35mm to 40mm and a reaction time of around 30 to 40 minutes – the system can be run in a similar way to a radiator system. Flow screeds offer better thermal conductivity than sand and cement, and being thinner and lighter means that they can be suitable for both renovations and new builds

How much does underfloor heating raise floor levels?

Underfloor heating will usually raise the profile of the floor. The amount it is raised by will depend on a number of factors such as how much insulation you need to add, pipe size, and whether you need a screed and floor finish.

There are also some products that get ‘carved’ into an existing screed, in which case there would be no additional build up other than the final floor finish.

If you want to retrofit a wet water system or have concerns about excavating or raising the floor, then low profile systems are a good option. "These have the advantage of coming in different heights and designs which allows them to be installed relatively quickly and easily on most substrates without impacting on the floor to ceiling height of the room," says Mark Dowdeswell, Senior Category Manager at Uponor.

Where should I buy underfloor heating?

Ultimately, the efficiency and success of an underfloor heating system will depend on the quality and design. Choosing a supplier who offers a good design service and aftercare is important. A specialist underfloor heating company is often best placed to achieve this.

If the design is wrong it is unlikely that the homeowner will know until they have lived in the house for a whole heating season – by which time it might be too late.

Finally, if you are choosing to pair underfloor heating with an air source heat pump or ground source heat pump, it is a good idea to choose one supply and install company. Both are complex systems and getting the whole heating system to work in perfect harmony is essential to a warm and toasty home.

Now you understand the basics of underfloor heating types and how it could work in your project, find out what you can expect to pay for underfloor heating costs, including installation and projected running costs.

What to Consider When Buying a Bathroom Radiator

Bathroom Specific

It sounds obvious, but make sure the radiator and/or towel rail model is suitable for bathrooms. Many are powder coated and have a waterproof or rust proof top layer to help them withstand moisture in a bathroom.

Electric VS Plumbed-in Vs. Dual Fuel

Electric models are the easiest to install by a qualified electrician. They can be plugged in and work separately to the central heating.

Plumbed-in models connect to your hot water system – your boiler – and are controlled via your central heating system.

Dual fuel models offer the best of both – they can connect to your hot water system and feature an electric element that, using a T-piece fitting, can isolate the radiator or towel rail from the central heating. This means you can connect to your heating system during the winter months and switch to electric during the summer months when you don't need to use it to the heat the room.

Where to Install a Bathroom Radiator

If you're renovating a bathroom then the simplest solution is to put a new radiator or towel rail in the same place as the one you're replacing. This will keep costs down, if you're replacing like for like – a plumbed-in version for example – as the plumbing will already be in place. Just make sure to check measurements between the valves and the profile of the new emitter to ensure it'll fit.

If you're starting from scratch, or moving the position of the emitter then consider the position of plumbing and pipework or electric sockets; windows and doors; sanitaryware and the size and shape of the space to pick a model that works.

What is a BTU Rating?

British Thermal Units – or BTU – measures the heat output of a radiator. You need to work out the heat requirement of your bathroom to make sure you install a radiator that will keep your space warm. 

There a few things that will affect the BTU value such as the size of the room and the types of windows you have.

There are many online calculators or a qualified plumber will be able to help you work out the BTU value so that you can choose a bathroom radiator that will be efficient enough for the space.

Learning how to paint behind a radiator gives you the satisfaction of knowing that you’ve done a good job. You can look at your radiators knowing that the wall behind is the same colour as the rest of the wall.

When painting a room, you can take the easy way out and use a brush to paint as far as you can reach. This works well when refreshing a wall with the same colour, such as white on white. But if you want a pro finish, you need to go the whole way. Here you’ll find expert advice to help get the job done, the right way.

The tools you'll need for painting behind a radiator

• Paint
• Radiator roller
• Radiator brush
• Dust sheets
• Cling film
• Masking tape

How to paint behind a radiator without removing it

1. Prepare the area

Before you start, Nick Parsons, technical manager at Harris, says, “It’s essential to start by turning off the heating and allowing the radiator to cool completely.” He adds, “Once cooled, open a window to ensure proper ventilation before attempting any preparation or paintwork.”

The next step is to protect the surrounding area. Parsons says, “Begin by removing all furniture and obstructions from the space.” He adds, “Next, lay down a dust sheet and secure it in place with masking tape to prevent slipping and protect your flooring from any paint spills or damage.”

Now clean and prep behind the radiator. Parsons says, “Make sure the wall surface is clean and ready to paint.” He adds, “Use a damp microfibre cloth to wipe away any dust or cobwebs that may have collected behind the radiator. If the wall has any rough patches or flaky paint, give it a light sanding."

Finally, use clingfilm or tape plastic sheeting firmly in place to protect the back of the radiator. To finish, cover the skirting board with painters' tape, such as this Scotch Blue Original Multi-Surface Painter’s Tape from Amazon.

2. Use a paintbrush

A radiator will typically be one to two inches from the wall, so paint as far as you can reach with your standard paintbrush. Wiggle the brush down into the gap – top and sides – and pull it along to cover the area. Repeat until finished.

Jess Steele, heating design expert at Best Heating, suggests using a specialist brush to paint the rest of the wall behind a radiator. “For closer control, opt for a precision finish by using an extended-reach cutting-in brush with a shaped head or a longer, thin-handled brush with a short, angled head.” These are ideal for cast-iron style radiators.

3. Finish with a roller

To paint behind a radiator, you will need a long-handled mini roller. Steele says, “A long-armed roller will make it much easier to squeeze into narrow or awkward crevices and tight spaces.”

Apply the paint to the roller – be careful not to overload it – and start from above the radiator and roll down in smooth strokes inside the two radiator brackets. Next, work in from the sides up to the radiator bracket. Let the paint dry and repeat.

Steele offers a final tip, “If you have designer radiators – or any radiators – that do not project far from the wall, cover a flat pad with paint and slide it behind the radiator.”

The tools you'll need to remove a radiator

• 12” adjustable spanner (like this WISEUP Adjustable Spanner from Amazon)
• Grips/Pliers (like these KNIPEX Pliers Wrench from Amazon)
• Jointing compound
• Bowl
• Towel
• Protective sheeting
• Radiator bleed key (like this Solid Brass Clock Keys from Amazon)

How to remove a radiator to paint

1. Switch off radiator valves

The first step to removing a radiator is to isolate the radiator by switching off both radiator valves. This will stop any water from coming through the pipes.

It's important to note that different valves work slightly differently - you may be able to switch off the valves using the cap, but if not you will need a large adjustable spanner to turn off the valve. Turn clockwise to turn off.

2. Prepare the area

Place a bowl under the radiator valve. If you are removing a large radiator then use a large bowl/container and have a second ready in case you need it.

Place a towel around the valve to catch any splashes, and to protect carpets you can put down plastic or waterproof sheeting. Cover an area of at least 1m from the radiator, and cover an area to place the radiator once removed.

3. Drain the radiator

Undo the large nut on one side of the radiator that attaches to the valve. Next, and this is important, use a pair of grips to keep the radiator valve steady and use an adjustable spanner to undo the nut. Do this slowly. The water will then drain into the bowl.

4. Remove the radiator

Once the water stops coming out, undo the nut at the other end of the radiator. Remember to place a bowl under the valve and use the grips to steady it.

Next, lift the radiator off the wall and tip up into the bowl to remove any remaining water. Once empty, turn the radiator upside down and store. Place tape over the radiator valve thread to stop any dust/dirt paint from getting into the pipes.

5. Replace the radiator

After you have finished painting the radiator, you will need to place it back.

First, remove the tape and wipe the inside of the valve clean with a clean cloth. Then, add a little jointing compound inside the valve thread with your finger, place the radiator back on the wall, tighten the nuts, and switch the valves back on.

Next, open the bleed valve – commonly positioned at the top right – until water starts to dribble out. You may need to repressurise your boiler afterwards.

When painting behind a radiator, there’s a good chance that you’ll be painting over wallpaper and painting wooden doors to complete the decoration of a room. When you’ve finished decorating, make sure to check out our how to clean paint brushes guide to get them ready for your paint project.

Radiators not working, especially as temperatures drop, can be incredibly inconvenient for homeowners. Radiators work hard for us for many months each year, taking the chill off the cooler evenings of spring and autumn and keeping us cosy in the coldest weeks. But even the best radiators will occasionally need a little maintenance to keep them running efficiently.

The good news is that there is much you can do yourself. Other times you’ll need a competent professional. 

Read our essential guide to find out how to tackle even the most troublesome radiator (and boiler) problems as well as how to keep your heating system in tip top condition.

Radiators Not Working Because They are Hot at the Bottom and Cold at the Top

This is a common sign of radiators not working properly – as well as a cold band at the top of the radiator you may also find the radiators are making strange gurgling noises. It’s normally caused by a build-up of air at the top of the radiator, which tends to happen naturally over time.

This problem is easily solved by bleeding the air out of the radiators and this is a simple job that you can do yourself. 

One for the professionals? This is easy enough to tackle yourself; if you find yourself getting stuck, then by all means call in a professional.

Radiators Cold at the Bottom but Hot at the Top 

This is another common sign of radiators not working that spells less than cosy rooms, and it’s probably because of a build-up of debris that has settled at the bottom of the radiator. 

To flush all of that muck out you’ll need a professional to conduct a power flush of your system. For a couple of radiators, this could take one or two hours; for a whole heating system expect this to take the best part of a day.

One for the professionals? Yes – this isn’t a job for DIYers. 

Radiators Taking Too Long to Warm Up 

If you find that your radiators are becoming more sluggish, it’s probably because your system is starting to get blocked up with muck and debris. This reduces the effective size of the pipes, meaning that less water is flowing round the system. 

The answer is a flush or cleanse; this will take the best part of a day. To prevent the problem happening in the first place, you can ask your heating engineer to fit a system filter, and this will take an hour or so.

One for the professionals? Yes – call in a reputable professional for both the flush/cleanse and to fit the system filter.  

Some Radiators Not Working, While Others Are Warming as Normal

If some radiators are much cooler than others, then your central heating system needs rebalancing. Apart from the discomfort of cold rooms, there’s a good chance you’ll be spending much more on fuel bills than you need. 

There are several reasons for this problem; often it is because the TRVs (Thermostatic Radiator Valves) have not been adjusted correctly. 

You can either rebalance the system yourself, or call in a professional.

One for the professionals? You can do this yourself; if you’re not confident doing this, call in a professional.

Boiler Pressure Too Low

If your boiler pressure is too low, you’ll notice either that your heating has become less efficient or the pressure gauge on your boiler turns to red (an optimum pressure is just above 1 bar to 1.5 bar). 

There are several reasons for this problem: it may be that there is a water leak somewhere in the system or the pressure has fallen after bleeding a radiator.

Repressuring the boiler is straightforward and can be done on a DIY basis. There are two ways to tackle this. You can either do this via an external filling loop or an internal filling loop (with or without a key).

One for the professionals? Normally you can do this yourself. If you have any doubts about how to repressurise your boiler, your heating engineer will be able to help.

Tips for Preventing Your Radiators or Boiler from Breaking Down

The first thing to do is get a service in the summer months, to make sure everything is working as it should ready for the winter months. You can also run the heating system every now and then, maybe once a month or every other week, leading up to winter to make sure it is working well. 

You can also check the pressure on the boiler, especially in the autumn - you are looking for the pressure to be just above 1 bar up to 1.5 bar.

One for the professionals? Some of this you can do yourself, such as checking your system during the summer months; for a service you’ll need to call in a professional. 

Looking to add the best designer radiators for your home? Whether you want your heat emitters to match a contemporary new build, or are looking to refresh your existing interiors, designer radiators shouldn’t just look great, but also work efficiently in your home and for your lifestyle. 

When choosing radiators for any home, taking heat output into account based on rooms size is essential before looking into colours or designs — this is commonly known as calculating the BTU (British Thermal Unit) energy requirement of the room.

What's the Best Designer Radiator?

Contemporary in both design and appearance, the Jaga Knockonwood range is catered specifically to blend with modern home interiors. 

Unusually covered in a wood vaneer (sourced from Forest Friendly timber, no less), the durable design actually withstands the heat required remarkably well while Jaga boast the surface of the radiator is safe to touch even at temperatures up to 90º — a bonus for interior-minded young families.

But that's not the mean this radiator is all style and no substance, the unit is equipped with a Dynamic Boost Effect technology for an extra kick on those cold winter mornings, as well as a great BTU rating. 

While designer radiators tend to lean towards the more contemporary end of the spectrum, the Arroll Montmartre is a masterclass in blending the timeless, delicate designs of traditional cast iron radiators with modern efficiency. 

The radiator is supplied with solid wall brackets kit and air vent and, as is so beloved about cast iron designs, has a high heat retention so they stay warm long after you turn your central heating off. 

The daring industrial appearance only belies the power-house nature of this designer radiator. 

The Terma ribbon horizontal radiator is made from shaping mild steel into six coiled columns so a truly stand-out finish, but the great heat output of this model is what makes it truly worth your while. 

Sleek and simple in its design, Reina's Neva series is perfect for those with limited wall space and a tight budget. 

The vertical steel is finished in a high quality powder-coated finish to match any home style and comes with all the fixings to help with a mess-free and easy installation. 

Blending seamlessly into a bathroom, this glass mirror radiator saves on space and energy to heat. Warmed by infrared technology, the mirror won't steam up like a regular mirror while also providing a long-lasting and quick heat. 

Supposedly, as a result of the infrared heat airborne allergens are prevented from circulating spaces and the radiators been reported to help those with high blood pressure, poor blood circulation and joint stiffness. 

Add a true statement feature to your living space with this sharp, hexagonal design. Efficient with a great heat output, the Hex radiator also includes handy peg branches on which to hand towels in a kitchen or bathroom — or even a scarf before braving the winter weather!

Small but mighty, Milano's Aruba design kicks out a fair amount of heat for its size and looks great while doing it, although you may have to be careful in which room you position it — while it is good for it's size, it is still a small radiator so won't be able to keep up with large rooms by itself. 

Careful attention to detail – specifically to the low-profile – elevates this radiator from being a functional bit of kit in the corner to a feature for your home. 

The slimline  Wickes' Soap Ellipse radiator is perfect for use in either a family bathroom, living room or entry way where it's multi-use design as a full length mirror comes very much in handy. 

Featuring infrared technology and a waterproof touch screen control, this radiator (which can be hung horizontally or vertically) has built-in sensors that control an even heat output — perfect for busy families. 

How to Buy the Best Designer Radiator

Research is always key when investing in any radiator but, with the extra price tag that comes attached with some designer radiators, never has it been more true. 

The best place to start is with the dimensions of your room: find out the required BTU rating and make a note. 

Then, work out where in your room your radiator is best placed. Gone are the days where radiators were relegated to under the window; vertical designs and extra modern efficiency have made it possible to get a little creative in their positions. 

Once you have your BTU and designated space size, start looking into different designs — the world is your oyster these days when it comes to heat emitters so try not to get overwhelmed! 

Always make sure you central heating system is compatible with your chosen radiator and consider the cost of installation and added extras like valves and wall fixings before purchasing. 

Are Designer Radiators as Efficient as Regular Radiators?

In a word, yes, designer radiators are as efficient as regular radiators — they just come in a prettier package! 

Usually made from higher quality materials, such as steel, aluminium or glass the heat tends to be conducted more easily, meaning your home gets hotter faster. 

Time spent on the beautiful forms and design can result in more energy efficient radiators which are cheaper to run than the white rectangular models of times gone by. 

Need some contemporary designer radiator ideas? You've come to the right place. Adding a designer radiator will not just make your home more efficient but, with the huge strides that have been taken in designs over the last couple of years, can become a beautiful feature in its own right.  

When it comes to choosing radiators, there’s pretty much a radiator for every style these days from an elegant take on classic white styles and slimline vertical and horizontal radiators to daring metallic finishes and wonderfully colourful designs. 

And that's not to mean opting for a designer radiator idea will have you out of pocket - many hardware and bathroom stores such as B&Q, Victorian Plumbing and Screwfix have some amazing off-the-shelf models. 

So, we’ve gathered up all the different options to give you an idea of what’s out there and to inspire a room transformation that’s practical and will fit into a modern home design.

1. Choose a Contemporary Designer Radiator Idea to Reflect your Style

Reflective radiators are a great choice for kitchens and living spaces where you want to maximise the impact of any light shining into the space. The flat, wide panels are really efficient in this model and the slimline design means it won't be too intrusive in high-traffic areas.

The powder-coated finish steel will also blend seamlessly with whatever interior theme you choose — adding a little glitz alongside dark furniture, or matching an neutral colour scheme. 

2. Add Some Visual Warmth with Comforting Coppers

If you want to make a room feel cosy and contemporary, consider choosing a copper finish to a classic design. 

Modern radiators don't always have to be next to a window – in fact some suggest that they're more effective positioned elsewhere – so adding a style like this to a bold, feature wall turns installing a radiator from a requirement into an active design choice.

3. Think about Texture when Buying a Designer Radiator

Who said white radiators have to be boring? Designer radiators with some tactile intrigue look more like pieces of art than a practical heat emitter. Perhaps lean into the look and adding some LED strip into your lighting design behind the unit for a truly stand-out look.  

4. Personalise to Your Taste: Add a Bold Colour or Finish 

There are whole ranges of colour choices, patterns and interesting patinas out there so for a room where you want to impress – a dining room or open-plan living and kitchen area – find the perfect style to make a big impact.

5. Keep Your Designer Radiator Pared-back and Elegant

Contemporary doesn't have to mean in-your-face — flat panel radiators in a dark grey or black are understated timeless options. 

6. Create a Handy Feature for a Bathroom

With the advent of flat panel and slimline designs becoming far more mainstream than they were even five years ago, towel radiators have come along in a big way. 

Gone are the days when you bang you elbow coming out of the shower on a great mass of steel. Sleek, narrow forms are available pretty much anywhere with option that will suit even the smallest of spaces.

7. Think Vertically for New Rooms with Big Windows

Whether you're updating an existing room, creating a new space in an extension or start from scratch with a self build, there's no getting away from the size increase of window styles in our houses. 

So, when competing with huge swathes of glazing opting for a vertical orientation with your new radiators will provide a sleeker, more polished look.

8. Choose a Designer Radiator which Heats Open-plan Spaces

Almost all modern house renovation/extension/self build designs feature an element of open-plan so making sure your heating system can keep up is essential. 

This can mean a couple of smaller, discrete emitters dotted around a large room, or one large, strategically positioned unit. As with any room, make sure to calculate the BTUs required before buying a radiator using an online calculator. 

9. Stay On-trend with a Matte Finish

Sanitarywear and fixtures of all kinds now comes with options for a matte black powder-coated finish, so why shouldn't your towel rail match? 

Perfect for making a bold impression with a bathroom design interesting radiator shapes with a matte colour could be the finishing touch your space is after.

10. Brighten Up Your Spaces

Add a colour pop to a bathroom or bedroom, where we tend to keep colours neutral and calming.  

11. Invest in Smart Capabilities for Electric Radiators

When you're choosing emitters, opting a for an electric product which can be controlled to a smartphone or tablet for quick and easy control is definitely the way to go. 

12. Small and Mighty Designer Radiators

Generally with radiators, the bigger the size, the greater the heat output, but as radiators are more and more efficient, a smaller format might suit your room fine. 

Once you've worked out the BTUs your room requires, consider installing a compact – still still fabulous – radiator like this Chrome option. 

13. Go All-in with an Industrial-style Designer Radiator

Whether you are matching a whole-house style or just was a few interesting and unique statement features, this radiator is sure to bring a beautiful warmth and comfort to any room.

When radiators get older they become less efficient at heating a room as sludge builds up inside. This can be treated by flushing the system through with a chemical solution, but if a radiator is too far gone the results won’t be that effective.

Replacing a radiator not only results in more heat being pumped into a room, but by using a stylish replacement it can also really alter the appearance of the room. The newest designs of modern radiators take up far less space than their older counterparts but deliver the same output. And, compared to the functional designs found in many older properties, modern radiator panels are pretty good looking, too.

Before you buy a replacement radiator, you’ll need to work out what size panel you need. Radiator output is measured in British Thermal Units (BTU) and this figure is found on the radiator packaging. To work out the BTU figure for the room, multiply the height by the width and length (in feet) and then multiply this figure by four. Alternatively, you can tap the room dimensions into an online BTU calculator and have all the hard work done for you.

Perhaps most importantly, replacing a radiator does not have to be a complicated job and so can carried out on a DIY basis meaning you won’t have to pay a penny for labour.

Step-by-step

1. Turn the boiler off; check that the water supply to the boiler is off, too. Then drain the system. At least one of the downstairs radiators will have a draincock on it. Attach a length of garden hose to the draincock and run the hose outside to a point lower than the radiator and let the system drain down. Opening up the bleed valves on the radiators helps to drain the water out of the system.

2. Put some rags under each end of the old radiator to catch any drips and undo the valves. Get someone to give you a hand lifting the radiator off the wall; it will be heavy and is likely to contain some filthy water that should be drained into a bucket before you try to take it out of the room. Remove the old brackets.

3. Decide on the position for the replacement radiator. Modern radiators are generally smaller than old-style units with the same BTU output, and normally its just a case of centralising the new radiator between the old valves before running new pipework to suit. To centralise the radiator, measure between the old valves, divide by two and mark this point on the wall with a vertical line. Find the centre line of the radiator and then measure out from this point to the centre of the bracket supports. Transfer these measurements to the wall. Use a spirit level to get all the lines vertical.

4. Use the template that comes with the radiator to mark off the bracket hole positions on the wall. Drill the holes, insert rawl plugs and screw the brackets to the wall.

5. Wrap PTFE tape around the threaded parts of the radiator valves. This helps to seal them and keep the radiator watertight.

6. Fit the valves. Do up the main body of the valve with the correct hexagonal key (available from DIY stores). Some valves have a hexagonal nut on the outside that can be done up with a 17mm spanner. Use an adjustable spanner to tighten the outer part of the valve onto the main body. Now hang the radiator on the brackets. Get someone to help if its a large panel.

7. If the pipework for the old radiator runs under the floor, as here, remove the old valves and lift the floorboard/s to get access to the pipes. If the pipes run through a wall you can either decide to extend them along the face of the wall, or, if you can get access to the other side of the wall, run new pipes to meet the radiator valves.

8. Measure up and run the new pipework to the radiator valves from the old radiator feeds. Use a copper pipe cutter rather than a hacksaw to cut the pipework to length. Check that everything fits together and that there are no stresses at any of the joints.We recommend that you use solder ring or Yorkshire-style joints (the pic shows a solder ring bend the bumps on each end contain the solder. The solder at each end melts when heat is applied, and makes the job of getting a watertight joint much easier for the DIY plumber).

9. Take the pipework apart and clean all the ends of the copper pipe with wire wool. Put a smear of flux on the end of each pipe and reassemble the joints.

10. Put a flameproof mat behind the parts to be soldered and then heat the joint evenly with a butane torch. The flux will burn off quickly and the solder will melt within 20-30 seconds. Stop heating the joint when you see the silver solder form a ring at both ends of the joint. As you can see from this picture, disturbing floor and skirting boards to get at pipes can create a bit more work in the form of wall repairs. This is particularly true in older houses.

11. If the pipework is coming up through the floor, mark off and cut holes for the pipes to come through the floorboard. Put the board back in position but dont fix it in place yet. To connect the radiator, slide a nut and olive over each pipe, feed the copper pipes into the bottom of the valves and tighten the nut with an adjustable spanner.

12. Refill the system with water and check for leaks at the soldered joints and at the valves.

13. Switch the boiler back on and turn on the central heating system. As the system heats up, check again for leaks. If you lifted a board this can be nailed back in place now mind the pipework. The last job is to bleed the air out of the new radiator. In some cases you’ll need to top up the system (as in step 12) as the air is replaced by water in the radiator. As soon as water starts to bubble out of the bleed valve, tighten it up. Modern double radiators have a bleed valve in each panel, so don’t forget to bleed from both.

Choosing radiators, whether to finish your self build or to update a renovation project, can often by an afterthought once the majority of the interior is complete.

However, planning ahead can be key to saving you money on the best radiator to compliment your design scheme and space available.  

21st century radiators are increasingly inventive in style, colour and form, but it is important not to lose sight of their purpose: to heat your home. Cluing up on what would work best for your home and researching the best prices should always be a priority.

Consider Heat Output When Choosing Radiators

The first step in choosing the right radiators for your home is calculating the BTU (British Thermal Unit) energy requirement of each space. “All radiators have a specified heat output so once you know how much heat the room needs you can choose the type, size and style to suit your taste and the room,” says energy-efficiency expert Tim Pullen.

A Gas Safe Register plumber or heating engineer is best qualified to work this out for you. However, online BTU calculators (see manufacturers’ and suppliers’ websites) will help to give an indication.

Factors such as these are all used to estimate the suitable heat output:

• the dimensions of each room
• the size of any window openings
• how many external walls are present

How Big Should my Radiator Be?

With a large number of manufacturers, it’s possible to specify radiators in a wide range of sizes to suit your needs. As a general rule, the larger the size, the greater the heat output. If, however, you’re stuck for space or simply prefer to be without radiators, skirting heating is a discreet, space-saving alternative.

What Should my Radiator be Made out of?

Traditionally, radiators were manufactured from steel due to its strength, efficiency and flexibility. Beautiful brushed and polished finishes can be achieved in stainless steel and the material is extremely durable. Steel is also impervious to water, meaning to can be used in any domestic heating system, and is usually the cheapest choice.

Lightweight aluminium options allow homes to be heated quickly and efficiently and can offer a more modern, sleeker aesthetic. “They are usually the most effective in terms of efficiency and they are the ‘greenest’ in terms of their manufacture,” explains Dave Thornback, UK sales manager at Vasco. “Added to the fact that they can be completely recycled at the end of their life.”

As they only require a low water volume, aluminium radiators can be mounted on most walls but although the material is quick to heat up, they also lose heat rapidly once switched off.

Cast Iron is another traditional choice, particularly when specified for column radiators. Unlike aluminium, this material takes its time to warm up, but will hold onto heat long after being turned off. It is also a heavyweight option, so ensure your floor/wall is structurally sound.

Among the more unusual but emerging options are stone and glass — which is not only energy efficient, but also gives scope for decorative artwork. However, glossy surfaces so not emit as much heat as matt finishes so it is usually an important consideration to make when deciding.

Other advances include graphite radiators and high-end designer towel warmer radiators made from brass as they offer exceptional quality and tending to suit traditional schemes.

Styles of Radiators

Style is the name of the game for modern radiators, as homeowners are no longer simply looking for efficient and pace-saving heat emitters. Consider shape early on; ladder designs are ideal for hanging towels in bathrooms and kitchens while contemporary wall-hung designs might looks best in a bedroom of living area.

Powdered coated, colour matched and acid-etched finishes are now available from many manufacturers and while luxury radiators can come with a high price tag, they usually offer a sleeker installation including hidden brackets for hanging your radiator on the wall.

Dual-energy radiators are a great option for bathrooms as they can be used when the central heating is turned off and electric options have come on leaps and bounds to be more efficient and a viable options for a modern home that won’t waste money.

Companies, such as The Economy Radiator Company, are also offering slimline models made of Italian aluminium, which are fully programmable and promote lower running costs. 

It’s not just electric radiators that are growing in popularity either. Low-surface-temperature radiators (LSTs) – commonly found in schools and hospitals thanks to their safety casing – are now being specified by homeowners to be used in conjunction with heat pumps.

While a number of leading brands, including Stelrad, Zehnder, Myson and Jaga, offer LSTs in different sizes according to available space, they are commonly more expensive than traditional radiators, but have the benefit of safety as well as efficiency.

For example, products such as Jaga’s Tempo LST radiator features a low-H2O heating element which is able to react to temperature changes quickly and efficiently, meaning that only the nominal amount of energy is used to heat the space.

Radiators in Period Homes

Period radiators are a real asset, but may require attention if they are to remain in efficient working order. Old radiators can suffer from cold spots, caused when sludge builds up inside — powerflushing will remedy this problem. Cast iron radiators coated in layers of unsightly paint can be shot-blasted. Both are tasks for the professionals.

Old models can also be sourced online or in reclamation yards, but Andy Triplow of The Old Radiator Company gives the following advice: “Be careful when buying from a salvage company as, although the old radiators may look robust, they can be easily damaged and may have cracks that you are unable to see. The gaskets, which seal the joints between the sections, are particularly susceptible to damage.”

Salvaged radiators can be reconditioned, but you may decide a reproduction offers a more straightforward solution.

What Valve is Best to Use?

Valves will not only impact on the overall look of your radiator, but choosing the right one will also impact on its functionality and the heat output — ultimately affecting your energy bills.

Manual valves are adjusted by hand and allow a constant flow of water into the radiator while thermostatic radiator valves (TRVs) not only enable you to manually set the temperature of individual radiators, but they also regulate heat output — automatically reducing flow to the radiator when the surrounding air temperature rises too high.

Digital programmable TVRs are also a very popular option of recent years as the desire for a smart home has infiltrated the mainstream market.

Installing TRVs – combined with a room thermostat and programmer – in a typical three-bedroom semi-detached home heated by gas can shave up to £75 off your annual bill according to the Energy Saving Trust.

Controlling the Temperature in the House

The control system will be largely dictated by the system being installed. It is essential that the control system must allow the temperature to be set for each room.

It is uncommon that a house will need every room to be heated to the same temperature at the same time (think guest bedrooms which receive occasional use). Getting that right will make a noticeable difference to the heating bill.

What’s more, with the popularity of smart homes, there are more and more innovations in central heating controls that allow homeowners to zone areas and adjust temperatures of individual rooms using apps.

According to the director of Heat and Energy Ltd David Hilton, “There are a number of wireless systems now that can control multiple rooms with no installation disruption. These systems typically have a control hub connected to the boiler that is accessed through an app on a phone or mobile device.

“Each room (or zone) has a thermostatic sensor on the wall and a motorised radiator valve. You then set the desired room temperature on the app and the sensor in turn sends a signal to the radiator valve to open and thus heat the room. When the room temperature is met, the sensor will signal the radiator valve to close down.”

Where to Install a Radiator

Just as you would plan space for kitchen units, sockets and switches, knowing where your radiators are best placed is just as important. 

If you are building anew or completely ripping out and starting again, plan the installation as you plan the decor and furniture. Traditionally radiators tended to be positioned under windows or on external walls, as cold air pushes the heat around the room, but with increasing standards of energy efficiency and airtightness in homes, there is a new flexibility around where radiators can be placed.

According to Ellie Sawdy of radiator specialist Bisque, placing a radiator under your glazing might actually undermine the efficiency of the system: “This can sometimes be ineffective, particularly in older properties where heat escapes through draughty windows. Look for tall, slimline options which can fit either side of a doorway, or a compact model which can fit in a tight alcove.”

Are some of your radiators in your home hot, while others are cold? Then it's time to learn how to balance radiators to help stop it happening. No-one wants cold spots, especially in the middle of winter, or hot spots in rooms that rarely get used.

When a radiator is not heating up properly, the lack of balance between radiators can be one issue. But luckily it is one that most DIYers can tackle, and the best bit is that it will cost you very little in the way of tools.

Here we reveal the tools and techniques you’ll need to balance your radiators and make sure every room is toasty when it's cold.

How to balance radiators: The tools you'll need

Five steps to balance radiators

1. Turn off central heating

The first step is to bleed all radiators. Then turn off the central heating and allow the radiators to cool down. Once all the radiators are cool remove the lockshield cap. It will typically have a push-on cap or one that is secured with a screw through the top.

2. Open radiator valves

Most modern radiators will have a TRV (thermostatic radiator valve) on the other side to the lockshield valve. This controls the level of heat and can switch off the flow of hot water. Older models will typically have what is known as a wheel head valve, which performs the same task.

Open up the valves on all the radiators in the house by turning them anti-clockwise. TRVs and wheel head valves can be turned easily by hand. However, lock shield valves will need a plastic adjuster or an adjustable spanner to open it up.

3. Check order radiators heat up

Turn the central heating back on and note down the order the radiators heat up. "Usually, the radiator nearest to the boiler will get warm first — it is important to take note of this when checking how your system is running," says heating expert Martyn Bridges.

"If the radiator closest to the boiler doesn’t get warm first, this typically means your system is unbalanced," he adds.

If you’ve got a lot of radiators, get help from another member of the household to work out the heating up order. Once finished, turn the heating off and wait while the radiators cool down.

4. Take temperatures

When the radiators are cool, switch the heating back on and go to the first radiator on your list. Turn the lockshield valve clockwise until it is closed and then open it by a quarter of a turn. Once the radiator has warmed up, take a temperature reading at the pipework leading to one of the valves.

Now take a temperature reading at the pipework leading to the valve on the other end of the radiator and open the lockshield valve gradually until there’s a 12°C difference between the two. (Allow a couple of minutes after each adjustment for the temperature to change.)

5. Check remaining radiators

Now check the rest of the radiators – ensuring there is a 12°C difference in temperature – in the system following the order on the list you noted previously. The further you move away from the boiler, you’ll find the lockshield valve will have to be opened more.

The last radiator may need to have the lockshield valve fully open to work at full efficiency. Your radiators will now be balanced and should work perfectly.

Balance radiators FAQs

What happens if radiators are not balanced?

Poorly balanced radiators will not work as they should when first installed. Typically it will cause issues as Bridges reveals: “If radiators are not balanced they can cause a number of issues such as cold spots in your home with uneven heating — meaning the system is ultimately running inefficiently.”

Effectively this means that some rooms will heat up quicker than other rooms. This will leave some rooms feeling too hot whilst others will be colder than expected.

Do I need a plumber to balance my radiators?

This is a job that you can do yourself, but if you have no experience it can take much longer to get the balance right. You will need patience, especially if you have a lot of radiators to balance. The more radiators that need balancing the longer the job will take. And you may end up with exactly the same issues you had before you started.

If not confident tackling balancing radiators the alternative option is to call in a plumber. The cost will vary depending on different factors, but as a rough guideline expect to pay around £100-£150.

Why is 12°C the optimal temperature difference between the two valves?

The temperature range between the two valves is considered the most efficient temperature difference for a radiator. Ultimately it is a compromise between efficiency and energy usage.

It will ensure that a radiator heats up a room effectively, but without using too much energy. Making it more efficient and cost effective.

Do you balance radiators clockwise or anti-clockwise?

A radiator will have two radiator valves, typically a lockshield valve and a thermostatic radiator valve (TRV). Bridges says: “You need to find the lockshield valve and turn it anti-clockwise toward the highest number on the dial (if it has numbers).”

This will turn the valve on and fully open it. The same applies to a TRV. Depending on what valve you have you may need an adjustable spanner to fully open a valve.
