Before you attempt to do anything with the radiator, you better make sure that the temperature is safe to work with. Turn off the valve that connects the radiator to the pipes and also shut down the boiler, just to be safe.

Now you need to leave the entire system completely cool down in a few hours before inspecting the radiator. Again, do remember to wear protective when you handle the radiator.

• Step 2: Find the bled valve and use it

In most models of hot water radiators, the bleed valve is usually located at the top and to the side of the radiator. In order to operate it, you will need to use a bleed key, flat – headed screwdriver or alike.

In order for the trapped air to get out, you need to turn the valve counter – clockwise. After that, you will hear a “hissing” sound of trapped air getting out and when the sound stop. Close the valve and the bleeding is done. There will be water leaking from the valve so use the rags to wipe them off.

But that is the easy part, the hard part comes before that which is to actually locate the bleed valve. As mentioned before, bleed valve may be located elsewhere apart from the top of the radiator. Here are a few hints for you.

Check every corner of the radiator and not just the surface. Detach the radiator to see if there is any “unusual” bolt or screw in or around it. The bleed valve is small and its appearance may fool people into thinking that.

It’s just a normal button or unimportant part of the radiator.

If you still can’t find the valve, chances are its cover by a protective layer. You will need to look out for a small and rounded cut on the radiator then try to graze or pry it open.

This should let you access to the bleed valve and operate it. But you need to do one more thing to bring you radiator back to effective operation.

• Step 3: Use the end cap (Optional)

In the rare case that you still can’t find the bled valve then this is the final solution: Loosen the end cap. For this to work you will need to use a wrench. Warp the wrench around the end cap of the radiator, tighten the grip and slowly turn it counter – clockwise.

The moment you the familiar “hissing” sound, stop and wait for the sound the stop. When you see water coming out then the trapped air is finally gone so quickly tighten the cap by turning the wrench clockwise. You are done then just move on to the next step.

• Step 4: Pressurizing

When all the trapped air has finally escaped, the boiler pressure must have changed a bit from the usual setting so you need to go there and check. If you see the pressure is not suitable then you have to adjust it.

What you need to do here is to look for the central filling loop. It’s a pipe that connects the boiler to the water source hence you can find it near the boiler. Re – pressurize the central heating – filling loop up to your preference and your radiator efficiency should be good as new now.
