Are your radiators cold at the top even though the boiler is on? This could be a sign you need to bleed your radiators. Other signs could include noisy/gurgling radiators. Follow our recommendations below on how to bleed your radiators.
1. Turn your heating on and identify which radiators need bleeding. Best practice however would be to bleed all the radiators. This is done from the bottom to the top floor of your home. This ensures when the air rises from one floor to the next that it can escape.
2. Turn off the heating and wait for the radiators to cool.
3. Get a cloth and radiator key so that you can open the valve and wipe up any water spilling from the radiator.
4. Open the radiator valve slowly and wait for the hissing to stop. Put the cloth underneath to catch any spillages.
5. Re-tighten the valve once the noise stops before too much water escapes. Clean up any excess water with a cloth. Check the pressure in the tank once you bleed each radiator.
6. Repeat this process for all radiators (going from downstairs first to upstairs last).
7. Turn the heating on again. This will allow you to check if you have been successful. Make sure no water is dripping from the radiators and that they are hot all over.
