Step 1) Fully open any thermostatic radiator valves, including heated towel rails, and run your central heating for ten minutes. Then turn off the system.
Step 2) Put the bleed key into the valve and slowly turn anti-clockwise. Take care when turning the valve. Have your cloth ready to shield your hand and a small bowl to catch any small drops of water.
Step 3) If there is trapped air you should hear a hissing sound as it escapes. As soon as water begins to drip out, close the valve.
Step 4) Check the rest of your radiators. Often trapped air will only occur in one or two.
Step 5) Turn the heating on and check there are no drips.
* TOP TIPS *
* Bleed radiators at least once a year to release any trapped air in the system.
* If your radiators are cooler in one area of the house, the radiators aren't properly balanced. The nearest radiators to the boiler are taking more than their share of the hot water from the system. Call in a local tradesman to fix it.
