How Do I Remove a Radiator?

Removing a radiator may seem daunting, but with the right tools and knowledge, it’s a straightforward task. Whether you’re decorating, replacing a radiator, or performing maintenance, here’s a step-by-step guide to help you remove a radiator safely and efficiently.

Tools You’ll Need

• Adjustable spanner

• Radiator key

• Bucket or large container

• Towels or cloths

• Screwdriver

• Pipe wrench (optional)

• PTFE tape (optional)

Step-by-Step Guide to Removing a Radiator

Step 1: Turn Off the Heating System

Before starting, turn off your heating system and allow the radiator to cool down completely. This ensures you won’t be working with hot water, which can be dangerous.

Step 2: Close the Valves

Locate the two valves on either side of the radiator. One is the thermostatic radiator valve (TRV), and the other is the lockshield valve. Turn both valves clockwise to close them. The TRV can usually be turned by hand, while the lockshield valve may require an adjustable spanner or radiator key.

Step 3: Drain the Radiator

Place a bucket or large container under the TRV to catch any water. Use an adjustable spanner to loosen the nut connecting the valve to the radiator. Once loose, water will begin to drain. Open the bleed valve at the top of the radiator using a radiator key to allow air in, which helps the water drain more quickly.

Step 4: Disconnect the Valves

Once the water has drained, use the spanner to fully disconnect the TRV and lockshield valve from the radiator. Be prepared for any remaining water to escape, and have towels or cloths ready to catch it.

Step 5: Remove the Radiator

With the valves disconnected, you can now lift the radiator off its wall brackets. Radiators can be heavy, so it’s a good idea to have a helper if needed. Tilt the radiator slightly to drain any remaining water into the bucket before moving it completely.

Step 6: Cap the Valves (Optional)

If you’re leaving the system drained for an extended period, consider capping the open valve ends with PTFE tape and a cap fitting. This prevents any residual water from leaking.

Step 7: Reassemble and Bleed (When Reinstalling)

When reinstalling the radiator, reverse the steps above. Reconnect the valves, secure the radiator to the wall brackets, and open the valves. Finally, bleed the radiator to remove any trapped air by opening the bleed valve until water starts to trickle out.

Conclusion

Removing a radiator is a manageable DIY task if you follow the steps carefully and have the right tools. Always ensure the system is cool and the valves are securely closed before starting. If you encounter any difficulties or are unsure about any step, don’t hesitate to consult a professional for assistance.
