How to Remove a Radiator

Print this article Share

You may need to remove a radiator if you want to paint or wallpaper behind it, or if you want to replace the radiator with a different size, style or heat output. It is a relatively easy task. Follow our simple guide to complete this job successfully.

Step 1

Preparation

Preparation

Turn off the central heating at least a couple of hours before attempting this task. Lay an old towel around the bottom of the feed pipes to catch any drips.

Step 2

Isolate Radiator

Isolate the radiator by fully closing the valves at both ends. Use the cap to tighten the valve completely and then pull off the cap and use an adjustable spanner to nip the valve closed.

Step 3

Shut-Off Cap

Shut-Off Cap

If you have a thermostatic valve fitted at one end of the radiator, you will require the shut-off cap that came with the radiator. Unscrew and remove the thermostatic valve to expose the valve pin. Screw the shut-off cap into place and tighten fully.

Step 4

Drain Radiator

Drain Radiator

Prepare a container, ideally a square plastic container such as an old ice cream tub. Partially loosen the instantor nut beside the radiator using your spanner, while taking care not to put undue strain on the copper pipe while doing this. It is a good idea to hold the copper pipe when operating the spanner to reduce any stresses that may cause a fracture in the pipe. Bring the plastic tub under the joint and fully loosen the nut. Pull the joint apart slightly to allow the water in the radiator to drain into the tub.

Step 5

Bleed Radiator

After it has been draining for a short while, open the radiator bleed valve with the key. This breaks the suction and allows the water to drain more rapidly from the radiator.

Step 6

Lift Away Radiator

Once the draining is complete, unscrew the instantor nut at the other end of the radiator to open the joint. The radiator will now be free to lift off its brackets. It may still have a small amount of water in it so have a bucket ready to catch this. Tip: you may need to remove the fittings installed in the bottom of the radiator if you intend to reuse these for the installation of a new radiator.
