How To Bleed A Radiator

Learn how to bleed a radiator, because your radiators will need bleeding occasionally, to reduce the air that gradually gets introduced into your central heating system. If you have radiators that are cold at the top – but hot at the bottom – then this is due to air collecting at the top, and you will need to bleed them to fill that space with hot water so your central heating system works as it should. Learning some simple steps could mean you never have to call plumbers Warrington for minor maintenance that will save you money while keeping you snug and cosy right through the winter.

Bleeding a Radiator: Step by Step

How to Bleed A RadiatorBleeding a radiator is simple when you follow our step by step guide:
  • Turn off the heating system
  • Place an old towel or small bucket underneath the valve to keep water off the floor
  • Locate your radiator bleed valve – it will usually have a “screw” that your radiator key will turn – the other end will be a metal blanking plate.
  • Turn the key slowly anti-clockwise, just a quarter turn.
  • Wait for the hissing to stop, and water to run from the hole
  • Turn the valve back off
It’s now safe to turn the heating back on again. Go and grab yourself a cup of tea, and then go back to the radiator after it has been allowed to heat up for an hour or two. If it is now consistently heated at the top as well as the bottom then give yourself a pat on the back: you’ve sorted it!

What if the Radiator is Cold at the Bottom?

Knowing how to bleed a radiator will not resolve this problem: this is most likely caused by a build up of sludge. This is not undertaken during your gas boiler servicing Warrington and most likely you will need to have the system power flushed to remove it.

If A Bleed Didn’t Fix The Problem…

If bleeding your radiator does not work, it’s time for you to call L & W Heating heating services, specialist Warrington Plumbers.
