How to Remove a Radiator

You might want to remove a radiator to paint your walls. Perhaps you need to fix a leak behind it. Or maybe you are replacing an old unit. Do not worry about calling a professional. You can safely remove a radiator yourself. It is a very simple DIY task. You just need the right guidance. This guide from Showers to You shows you exactly what to do.

Preparation is Key

Good preparation makes the job much easier. You must get everything ready before you start. This prevents a massive mess on your floors.

Gather Your Tools

You need a few basic things to begin. Grab an adjustable spanner and a bleed key. Find a small bucket to catch the water. You also need some protective sheets or old towels. These keep your floors completely dry.

Safety First

You must put safety above everything else. Turn off your central heating system first. Let the whole system cool down completely. Working with hot water is very dangerous. You should wear gloves and old clothes. This helps protect your skin from dirty water.

Isolating the Radiator

Next, you need to isolate the unit. Find the thermostatic radiator valve, or TRV. Turn this dial to the zero position. Then, look for the lockshield valve opposite it. Take off the plastic cap covering it. Use your adjustable spanner to turn it clockwise. Count the exact number of turns. You will need this number later.

The Removal Process

Now you are ready for the main event. You will finally remove a radiator from the wall. Take your time to avoid spills.

Draining the Radiator

Place your bucket under the TRV valve. Put towels down to protect your floor. Use your spanner to grip the valve body. Use another spanner to loosen the joining nut. Do this very slowly. Water will start dripping into your bucket. Open the bleed valve at the top. This lets air in and speeds up the flow.

Disconnecting the Radiator

Wait until the water stops flowing completely. Then, loosen the valve nuts on both sides. Gently tilt the unit to empty any remaining water. Keep your bucket close by. Dirty water can stain carpets quickly.

Lifting and Moving

Radiators are incredibly heavy when full of sludge. Always ask a friend to help you lift it. Lift it straight up and off the brackets. Carry it outside or lay it flat. Keep it on a protective sheet.

Sealing Pipework

You might leave the unit off for a while. If so, you should cap the exposed pipes. Use a proper stop end or cap on the valves. This stops any unexpected leaks. It keeps your floors totally safe.

Post-Removal Considerations

The job is not over once the unit is off. You have to think about the heating system. Here is what you need to do next.

Can You Use Central Heating Without It?

Many people ask if their heating will still work. The simple answer is yes. You can remove a radiator and keep the heating on. Just ensure the isolated valves are completely secure. Check them for any drips.

System Pressure and Refilling

Taking a unit off lowers your system pressure. You need to check your boiler gauge. Top up the pressure using the filling loop.

After replacing the unit, you will need to bleed it. Read our post on How to Bleed a Radiator. This helps remove trapped air.

If some rooms feel colder, your system needs adjusting. Read our article on How to Balance Radiators. This ensures even heat everywhere.

Storage and Reinstallation

Store the old unit safely out of the way. Keep it upright to stop sludge from leaking out. When you reinstall it, reverse the removal steps. Open the valves using the exact turns you counted earlier.
