Air in your radiator is a common problem, and it can lead to inefficient heating. To stop your radiator from filling with air, you need to bleed the radiator. Bleeding a radiator releases the trapped air and allows the hot water to circulate properly.
Here's how to bleed a radiator:
- Turn off your central heating system. This will ensure the water is not under pressure.
- Locate the bleed valve. This is usually a small valve on the top of the radiator. It may be covered with a small plastic cap.
- Place a small towel or cloth underneath the bleed valve. This will catch any water that may drip out.
- Use a radiator bleed key. These are available at most hardware stores.
- Turn the bleed key counterclockwise. This will open the valve and release the air.
- Listen for a hissing sound. This indicates that air is escaping.
- Continue turning the bleed key until water starts to flow. This means that all the air has been released.
- Close the bleed valve by turning the key clockwise.
- Turn your central heating system back on.
If you have multiple radiators, repeat the process for each one. After bleeding all the radiators, check if the heating system is working properly.
If you're not comfortable bleeding your radiators yourself, you can contact a qualified plumber.
