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.
