Bleeding your radiator
Bleeding your radiators is one of the eight most common home
repair jobs according to the independent consumer watchdog
Which? Trapped air can build up in radiators, causing them to stay
cold even when your heating is running. This inevitably results in
wasted energy and higher heating bills. Bleeding a radiator is a
relatively simple job; read on to find out how to do it for yourself.
1 Firstly, turn on your central heating so that all radiators are
running. Once they are on, check each radiator for cold spots. These
are most often found near the top. When you’ve identified which
radiators need to be bled, turn off the central heating system.
2 Each radiator should have a valve at the end, which can be
opened using a radiator key or flat-headed screwdriver. Hold the
key or screwdriver using a cloth and hold another cloth under the
valve to catch any drips of liquid.
3 When you release the valve, you may hear a hissing noise. This is
the trapped air escaping from the radiator. You will know when the
gas has all been released when liquid leaks from the valve instead.
As soon as you see the liquid, which may be black or brown in
colour, close the valve back up as quickly as you can.
4 After your radiators are closed back up, check the pressure gauge
on your boiler. If it has dropped below the recommended pressure
level, you may need to use the filling loop to bring it back up to the
correct pressure or your boiler may run inefficiently, hampering
your attempts to save energy.
