How To Remove A Radiator (for Home DIY) 


Removing a radiator can be a useful skill,  especially if you’re redecorating, painting, or simply replacing an old unit. 

While it might seem like a daunting task, with the right tools and a bit of know-how, you can safely and effectively remove a radiator from your home’s heating system.

Here’s a step-by-step guide to help you through the process:

Tools and Materials Needed:

  • Adjustable wrench
  • Bucket or large container
  • Old towels or rags
  • Bleed key
  • PTFE tape (optional, for reinstallation)

Step 1: Turn Off Your Heating

Before you start, make sure your heating is turned off and your radiators are completely cool. This is crucial for safety and will make the process much easier and safer.

Step 2: Turn Off the Radiator Valves

You’ll find a valve on both sides of your radiator — one is typically a manual control valve, and the other is a lockshield valve (which might require a plastic cap to be removed). 

Turn both valves clockwise until they can’t turn anymore. This isolates the radiator from the rest of your heating system.

Step 3: Bleed the Radiator

Use a radiator bleed key to open the bleed valve at the top of the radiator. This will release any pressure and drain the remaining water in the radiator into your bucket or container. 

Be prepared for water to dribble out; use old towels to protect your flooring and catch any spills.

Step 4: Disconnect the Radiator

Place your bucket or container under the valve connections. Use your wrench to loosen the nuts connecting the radiator to the pipes. 

Water will likely drain out as you disconnect these, so let it drain into the bucket. Once all water seems to have drained, fully remove the nuts.

Step 5: Lift the Radiator Off Its Brackets

Once the radiator is fully disconnected, carefully lift it off the wall brackets. 

Radiators can be heavy, so it might be a good idea to have a helper with you to avoid injury or damage to the radiator and wall.

Step 6: Cap the Pipes

Once the radiator is removed, there will be open pipes where the radiator was connected. 

It’s a good practice to cap these or at least ensure they are turned off at the valve to prevent any accidental leakage or debris entering.

Step 7: Drain Any Remaining Water

Tilt the radiator to drain any remaining water out of it. This will make it lighter and less messy to move or transport, especially if you’re taking it out of the house.

Step 8: Store or Dispose of the Radiator Properly

If you plan to reinstall the radiator or use it elsewhere, store it in a safe, dry place. 

If you’re disposing of it, check with your local waste management services for guidelines on disposing of old radiators.

Removing a radiator can seem intimidating, but by following these steps, you can accomplish this task with confidence. 

Remember, safety should always be your top priority. Whether you’re updating your room’s decor or replacing a radiator, knowing how to safely remove one is a valuable skill for any DIY enthusiast.
