How to Bleed a Central Heating Pump
Bleeding a central heating pump is a simple process that can help remove any trapped air, improving the circulation of hot water and preventing noise and vibration. Here are the steps to bleed a central heating pump:
1. Turn off the central heating system and allow the pump to cool down.
2. Locate the bleed screw on the pump, which is usually located at the top of the pump.
3. Place a towel or container underneath the bleed screw to catch any water that may come out.
4. Using a bleed key or screwdriver, slowly loosen the bleed screw in an anti-clockwise direction.
5. Listen for the hissing sound of air escaping from the pump.
6. Once water starts to come out of the bleed screw, tighten it back up in a clockwise direction.
7. Check the pressure gauge on the boiler to ensure it is at the correct level.
How to Bleed a Heat Pump
Bleeding a heat pump follows a similar process to bleeding a central heating pump. Here are the steps to bleed a heat pump:
