To identify which radiator needs heating make sure all radiators are switched on throughout your home. By doing this you can see which radiators need bleeding and which do not.
Be careful not to burn yourself and check that all your radiators are warming up. If a particular one is not getting warm it may need bleeding.
Before bleeding make sure you switch off your central heating and find the radiator that wasn’t working properly. Bleeding radiators will require a radiator key which you can buy one at your local hardware store for as little as £1.
At the top of the radiator at one end there will be a valve. You can attach the radiator key to the square bit in the centre.
Hold the key and have a cloth ready to catch any drips, then slowly turn the radiator key anti-clockwise.
If air is escaping you’ll hear a hissing sound. Once there is no more, liquid will come out and the valve will need to be closed quickly.
Check the pressure by having a look at the gauge on your boiler. The pressure should be between 1 to 1.5 bar but if it is too low, you’ll need to ‘top it up’. You can check our ‘how to top your boiler video’ on our website.
Afterwards, you may want to run another ‘hot test’ to check that your efforts have been successful. Simply turn your heating on, wait for all the radiators to heat up and check that the radiators are hot all over.
That’s it! It’s a simple and cost effective way to keep your home warm. If you’re still finding issues with the heating of your radiator please contact us.
