Getting rid of an air lock in a radiator involves bleeding the radiator to release trapped air, which can prevent it from heating properly. Here's how to do it, incorporating information from the provided reference:
-
Identify the Problem: If your radiator is cold at the top but warm at the bottom, it likely has an air lock.
-
Gather Your Tools: You'll need a radiator key (a small, specialized wrench) and a cloth or container to catch any water that comes out.
-
Locate the Bleed Valve: This is usually a small valve located at the top of one end of the radiator.
-
Prepare to Bleed: Place the cloth or container under the bleed valve to catch any water.
-
Open the Valve: Insert the radiator key into the bleed valve and slowly turn it counterclockwise. You should hear a hissing sound as air escapes.
-
Close the Valve: Once water starts to come out instead of air, close the valve by turning it clockwise. The reference mentions, "There right that seems to have cleared now and it's quite warm as well. So we'll shut that and then we'll do the other end," indicating that when the air is cleared and the radiator feels warm, you can close the valve.
-
Repeat if Necessary: If the radiator still isn't heating properly, repeat the process. You may need to bleed the radiator multiple times.
-
Check the Pressure: After bleeding all your radiators, check the pressure on your boiler. You may need to top it up.
By following these steps, you should be able to effectively remove an air lock from your radiator and restore it to its full heating potential.
