If you have central heating you 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.

This will ensure that the radiator runs more efficiently meaning that you will get maximum output. Which in turn makes them more cost effective than if there 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 and the know how, which you can find in this guide.
