Bleeding a radiator is required when air gets trapped in a central heating system. By removing this trapped air (bleeding) the efficiency and effectiveness of your heating is greatly improved.
Don't be scared however, as bleeding radiators can be done safely as a DIY project by just following a few basic steps.
The first signs are radiators that are not heating up as much as they should, or have noticeable cool spots. With your central heating turned on, a simple test is to move your hand over the surface of the radiator. If you notice it is warm at the bottom but cool at the top then this would suggest trapped air which can then be released. Take care – radiators can get very hot.
Bleed valves are where the air is released and will be located at the top of the radiator, often on the opposite side to the temperature regulator, but this will vary by manufacturer.
There are two types of bleed valve:
The screw type is found on more modern radiators and simply requires a flat head screwdriver to undo.
The key type is normally found on older radiators and requires a special radiator key to undo.
Once you have located the bleed valve and have tools to hand, you're ready to begin.
We hope you've enjoyed this post and found it informative, and now you've mastered the art of bleeding a radiator, why not take on your whole house! It's good practice to bleed the whole central heating system once a year. Should this be undertaken, start on the first floor with the radiator furthest from the boiler and then work back to the boiler on the same floor. Repeat the procedure on any upper floors.
Keep your house 'toasty' warm - a well maintained central heating system runs more efficiently, saving both energy and money.
