How to bleed a radiator
Feeling a little chilly? It might be time to bleed your radiator and you’ll be toasty again in no time. Don’t worry, it’s not as scary as it sounds!
Here's some super simple, step-by-step instructions on how to bleed your radiator

Step one
Turn your heating off and wait for the radiator to go cold.

Step two
At one end of the radiator (always at the top), there’ll be a valve you need to attach a bleed key to.

Step three
If air is escaping you should hear a hissing sound.

Step four
Wait until this stops and water is coming out. Remember to catch any drips.

Step five
Tighten up the bleed valve again, but don’t over-tighten.

Step six
Check your boiler pressure (re-pressurising it if needed) and turn your heating back on and your radiator should be working again properly.
