central heating | Bleeding a radiator
Often a radiator will become warm at
the bottom and yet cold at the top, this is due to Air inside of the
the Radiator which prevents the warm circulating water from reaching
the top of the radiator. To remedy this the radiator(s) will require
bleeding.
1. Ensure that the central heating is switched off before bleeding
or this can introduce even more Air into the system.
2. If you have a header tank ensure that the water supply is not isolated
to this tank! If you have a boiler which requires manually topping
up like a combi then top it up after and possibly during bleeding
(depending on how much pressure there is left in the system)
3. Ensure both valves at the bottom of the radiator are open.
4. Using a radiator bleed Key insert it onto the Brass bleed screw
at the top of the radiator.
5. Have some kitchen towel or a cloth to catch any drips and slowly
turn the key anti-clockwise, about half a turn. You should hear hissing,
which is air being forced out by the water.
6. As soon as water squirts through the bleed screw, re tighten it
and make sure it is not leaking before moving on to the next radiator!
7. Repeat this on all radiators.
8. Top up the boiler if necessary!
Bleed screws often become damaged as they are made from soft metal,
if this is the case a spanner can be used or An Adjustable spanner
to loosen the large Cap from the end.
