Bleeding your radiators helps remove trapped air, ensuring your heating system runs efficiently. Here’s a step-by-step guide:

Gloves (optional)
Steps to Bleed Your Radiators:
Turn Off the Heating
Ensure your central heating system is off and allow the radiators to cool. This prevents hot water from spurting out.
Locate the Bleed Valve)
The bleed valve is a small square or slotted screw at the top of the radiator, usually on one side.
Place a Cloth or Container Under the Valve
This will catch any water that drips out.
Insert the Radiator Key and Turn It Slowly
Turn the key (or screwdriver) counterclockwise (about a quarter to a half turn).
You should hear a hissing sound – this is the trapped air escaping.
Close the Valve When Water Starts Flowing
As soon as water (not air) starts to come out steadily, quickly turn the key clockwise to close the valve.
Check the Boiler Pressure
Bleeding radiators can cause the boiler pressure to drop. Check the pressure gauge on your boiler. If it’s too low, you may need to top up the pressure using the filling loop.
Turn the Heating Back On
Once all radiators are bled and the pressure is correct, turn the heating back on and check if the radiators heat evenly.
