Why bleed a radiator?

In your property you may notice that sometimes although the heating is on the radiator is not warm at the top of the radiator but is at the bottom. This is because systems can occasionally get air in them, blocking the water from flowing through the system correctly. This air needs to be removed to get the full potential from you heating system. This is known as bleeding the system.

Tools required:

Radiator Bleeding Key

Towel (optional – just in case)

Elbow Grease!

STEP ONE: Turn off your boiler. Make sure your boiler is off to prevent further air entering the system when you bleed it.

STEP TWO: Open the Valves. The majority of radiators will have two valves at the base which control the water in and out of the radiator make sure these valves are open before moving on to the next step.

STEP THREE: Place the bleed key in the bleed screw, the bleed key is designed to fit snugly over the screw; however over time the soft metals of both key and screw can deteriorate if this is the case a spanner can also be used.

Turn the key anti-clockwise slowly until you hear a hissing sound. This is the air escaping the system keep your towel handy as water may then escape radiator once the air has emptied. Once water escapes simply turn it clockwise until it is tightly closed.

This will need to be repeated on all radiators.
