When new water is added to a central heating system, a certain amount of air will get in to the system as well. Because of the wonder of physics all the air in the system will rise above the water into the high points of the system.

The most common area to find trapped air is in radiators. This is somewhat easy to detect as the air will reduce the quantity of heat radiated. With the central heating switched on, feel the top and then the bottom of the radiator - if the top is noticeably cooler than the bottom, there's a good likelihood that there's air in the radiator. In some extreme cases the whole radiator can be filled with air. If this is the case then the radiator will not heat up at all.

Getting this problem sorted involves the comparatively simple task of bleeding the effected radiators. All radiators come with a small tool called a bleed key. There will likewise be a protrusion near the top of the radiator, on one side, called the bleed valve. Before you open the valve, though you ought to ensure the ...
... water in the radiator is warm and that the central heating system is switched off. It islikewise a good idea to have a bowl of some kind on the floor below the valve just to stop water getting on the carpet.

To open the valve, insert the key and turn it half a turn anti-clockwise. You ought to hear a hiss as the air starts to escape. Once water starts to dribble out, close the valve again by turning half a turn clockwise. You ought to you do not over tighten it though as you will make your life harder if you have to bleed the radiator some other time.
Once you have bled all the radiators that need doing and the system is totally sealed again, you need to top up the water pressure in the system by turning on the mains cold water feed in to the system. The pressure required is ordinarily approx 1 and a half bar, but check the instructions for your particular central heating system. If you do not know how to adjust the pressure on you central heating system do not bleed your radiators, rather call in a qualified expert.
