When Should I Bleed My Central Heating Radiators

Do You Bleed Your Radiators With The Heating On Or Off? You should always bleed your radiators when the heating is switched off and the system has cooled down, because bleeding radiators with hot water flowing through the system increases the risk of scalds and burns.

How do I know when my radiator needs bleeding?

A good way to check if your heating system needs bleeding is to see if your radiators have cold patches at the top but are warm at the bottom. If so, you need to bleed them to let the trapped air escape and the hot water to circulate freely once again.

How long does heating need to be off before bleeding radiators?

Step 2: Switch the heating off The system needs to have warm water in it for bleeding radiators, so switch the heating fully off and wait for the radiators to cool a little. About 20 minutes should be perfect – the time it takes to sit down with a cuppa and a biscuit.
