Bleeding
Occasionally, as a side-effect of maintenance or because of another problem, air may build up in the radiators of a water-fed heating system. The air isnt heated to the same degree relative to its volume, so it will cause the radiator(s) to give off less heat than normal. To fix this, the radiator must be bled. This is possible because central heating systems are pressurised, and the water will move to displace the air that escapes. However, bleeding the radiators poses a new problem. A loss of pressure will result, because the system uses a fixed amount of water, which will cause the heating system to either run at a greatly reduced capacity, or not at all. To solve this, the water mains must be opened, and a fresh supply of mains water must be allowed to enter the system.
