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!
How do I bleed a radiator?
Here's some super simple, step-by-step instructions on how to bleed your radiator:
At one end of the radiator (always at the top), there’ll be a valve you need to attach a bleed key to.
If air is escaping you should hear a hissing sound.
Wait until this stops and water is coming out. Remember to catch any drips.
Tighten up the bleed valve again, but don’t over-tighten.
Check your boiler pressure (re-pressurising it if needed) and turn your heating back on and your radiator should be working again properly.
