Radiator maintenance

Bleeding your radiators is an important, safe and quick task that should be conducted annually. The process allows trapped air to be released. If your radiator is cold at the top but warm at the bottom, its more than likely that trapped air will be the problem. 
1. Turn off your central heating

2. Find the bleed valve - usually located on the side of the radiator

3. Place a cloth or bowl underneath the bleed valve to catch any water that may leak

4. To bleed the radiator, insert the bleed key into the bleed valve (located in step two) and carefully turn it anticlockwise. (Not too much, just half a turn will do) You will hear a hissing sound; this is the trapped air in your radiator escaping. You will know when all the air will have escaped because water starts to trickle out of the valve. 

5. Re tighten the bleed valve carefully and ensure it’s tight. Clear up any spills.

6. Switch the central heating back on once you have finished bleeding all the radiators in the house, making sure that all the bleed valves are tight so no air can escape.
