Bleeding a radiator is the process of removing air from the radiator.
Air can get trapped in the radiator for a number of reasons, such as when the radiator is not properly installed or when there is a leak in the system. When air is trapped in the radiator, it can prevent the radiator from heating properly.
To bleed a radiator, you will need a radiator key or a screwdriver, a cloth, and a bowl.
- Turn off your central heating system.
- Locate the bleed valve on the radiator. It is usually a small, square valve located at the top of the radiator.
- Place the cloth under the bleed valve to catch any water that may leak out.
- Insert the radiator key or a screwdriver into the bleed valve and turn it counter clockwise until you hear a hissing sound. This is the air escaping from the radiator.
- Continue turning the bleed valve until only water comes out.
- Tighten the bleed valve by turning it clockwise.
- Turn on your central heating system and check to see if the radiator is now heating properly.
- Top up the water pressure on the system via the filling link if required.
If you still have problems with your radiator, you may need to call a local plumber.
Additional tips for bleeding a radiator:
- Make sure the radiator is cool before you start.
- Do not overtighten the bleed valve.
- If the radiator is still not heating properly, you may need to add more water to the system.
- If you have a large radiator, you may need to bleed it multiple times to remove all of the air
