How to: Bleed a Radiator (Infographic)

Bleeding your radiators is something that you should do on a regular basis. As well as making your central heating system more efficient by removing excess air, it can also save you money on your heating bills, as an efficient system will use less fuel to heat your home.

Do I Need Any Special Tools to Bleed a Radiator?  

There are no special tools required for bleeding a radiator, however, if your radiators do not have a built-in radiator key and cannot be opened with a screwdriver, you may need to buy one from your local DIY store (you can usually pick up a radiator key for less than £2). It’s also a good idea to have a towel or cloth to hand, as a small amount of water may drip from the valve when you are removing the air.

How Do I Know When I Need to Bleed My Radiators? 

Ideally, you should bleed your radiators at least once every two months. However, if you notice cold patches on your radiators or they take a long time to heat up, this could be caused by trapped air. If this is the case, the only way to fix this issue is to remove the air by bleeding your radiators.

If you find that you are still experiencing problems after you’ve bled your radiators, you should contact a qualified engineer, as you may have a build-up of limescale or rust in your central heating system.
