Bleeding your
radiators
is quick, easy and
completely safe -
simply follow our step by step guide
Are your radiators warm at the bottom but stay cold at the top? 
You will need a radiator key to open the bleeding valves at the top of a radiator, a
bowl or
bucket to catch any dripping water and a cloth in case any water is spilt.
Switch off your heating to stop the circulation pump from operating and moving heating
water
and air through the pipes.
To prevent hot water or steam leaks causing burns, you will need to wait for the heating
to
cool down, this will take approximately one hour to make sure that all the radiators are
cold.
It is normal for air to build up in your heating system overtime, if this happens you will need to bleed your radiators to make sure your heating is working at full efficiency to heat your home.
The bleed point is usually located on the upper side of the radiator, it's a small round
hole with a square inside, place the key in the bleed point with the bucket underneath
and
hold your cloth against the wall to protect from spray.
Open the bleed point, carefully turn the radiator key anti-clockwise until you start to
hear
a hissing noise, this is the air coming out of the radiator.
Let some water run out then slowly turn the radiator key clockwise to close the bleed
point
(Not too tight, otherwise you might damage the valve)
Switch your heating back on. Make sure you check the water pressure of the system, by
looking at the pressure gauge or digital display on the boiler, the boiler should read
between 1 to 1.2 bar of pressure.
All the radiators should now be warming up evenly
