Removing a radiator involves a series of steps to safely disconnect it from your heating system. Here's a breakdown of the process:
-
Turn off your heating system: This is the first and most crucial step. Make sure the system is completely cooled down before proceeding.
-
Turn off the radiator valves: Locate the two valves connected to your radiator, typically at the bottom. These are usually the thermostatic radiator valve (TRV) and the lockshield valve. Turn both valves completely clockwise to shut off the water supply to the radiator. Sometimes older systems only have one valve. In that case, shut off the main water supply to the heating system.
-
Drain the radiator: You'll need a radiator bleed key, a container (like a bucket), and some old towels to catch any spills.
- Attach the bleed key to the bleed valve (usually located at the top of the radiator).
- Slowly open the bleed valve by turning the key counter-clockwise. You should hear air hissing out.
- Once water starts to trickle out, close the bleed valve.
- Place your container under one of the radiator valves.
-
Loosen the Union Nuts: Use an adjustable wrench to loosen the union nuts connecting the radiator valves to the pipes. Be prepared for water to leak out. Have your towels ready!
-
Disconnect the radiator: With the union nuts loosened, carefully disconnect the radiator from the pipes. You may need to gently tilt the radiator to encourage any remaining water to drain out.
-
Lift it off the brackets: Radiators are typically hung on brackets attached to the wall. Carefully lift the radiator upwards and off the brackets. This step may require assistance, especially for larger radiators.
Important Considerations:
- Water Mess: Be prepared for water to spill during this process. Have plenty of towels on hand.
- Weight: Radiators can be heavy, especially when filled with water. Get help if necessary.
- Draining the Entire System: If you're removing multiple radiators, it might be easier and cleaner to drain the entire central heating system first. Consult a professional if you're unsure how to do this.
- Capping the Pipes: After removing the radiator, you will need to cap the exposed pipes to prevent leaks. Purchase appropriate pipe caps from a hardware store.
- Professional Help: If you're uncomfortable with any of these steps, it's best to call a qualified plumber or heating engineer. They can safely remove the radiator and cap the pipes.
- Disposal: Check your local regulations for proper disposal of the radiator. Metal recycling centers often accept them.
