How to remove a radiator on a combi boiler system
Radiators are an essential component of a combi boiler system. They provide warmth and comfort in our homes, especially during the colder months. However, there may come a time when you need to remove a radiator, whether it’s for routine maintenance or to make room for renovation. In this guide, we will walk you through the step-by-step process of removing a radiator on a combi boiler system.
Safety first: Before starting any work on your combi boiler system, it’s important to ensure your safety. Switch off the boiler and close the valves on both ends of the radiator. This will prevent water leakage and potential damage. Make sure you have the necessary tools, such as a wrench, adjustable spanner, and a container to catch any water that may drip during the process.
Step 1: Draining the system: To remove a radiator, you first need to drain the combi boiler system. You can do this by attaching a hose to the drain valve and releasing the pressure. Place the other end of the hose into a suitable container to collect the water. Open all bleed valves and allow the water to drain. Once the system is empty, close the bleed valves again.

Use a wrench or an adjustable spanner to loosen the compression fittings on both ends of the radiator. Once loosened, the fittings can be easily unscrewed by hand. Keep the container handy, as there may still be residual water that will drip out when you disconnect the radiator.
Step 3: Removing the radiator: Once the radiator is disconnected, carefully lift it off the wall brackets. Radiators can be heavy, so it’s advisable to have assistance to avoid any accidents or injuries. Once removed, inspect the brackets for any damages and make any necessary repairs or replacements before reinstalling a radiator or leaving the space unoccupied.
Removing a radiator on a combi boiler system may seem like a daunting task, but by following these steps, you can successfully complete the process. However, if you’re unsure or uncomfortable doing it yourself, it’s always best to consult a professional plumber who can help you safely remove the radiator and address any other heating system concerns you may have.
Step-by-step guide to removing a radiator on a combi boiler system
Removing a radiator from a combi boiler system may be necessary for various reasons, including redecoration, maintenance, or repairs. Follow these step-by-step instructions to safely and efficiently remove a radiator from your combi boiler system.
Before You Begin
Before starting this process, make sure you have all the necessary tools and equipment. This will typically include a radiator bleed key, adjustable spanner or wrench, bucket or old towels to catch any water that may leak, and radiator caps or plugs to prevent any water from leaking out. Ensure that the boiler is turned off and the system is cool before proceeding.
Step 1: Find the Isolation Valve
The first step is to locate the isolation valve, which is usually located at the bottom of the radiator on the same side as the pipe. Once located, use your adjustable spanner or wrench to turn the valve clockwise until it is fully closed. This will shut off the water flow to the radiator.
Step 2: Bleed the Radiator
Before removing the radiator, it is important to release any pressure or air inside. Using your radiator bleed key, open the bleed valve (usually located on the opposite side of the radiator) slowly. You will hear hissing as the air escapes. Once water starts to come out, close the bleed valve. Keep a bucket or old towels handy to catch any water that may leak.
Step 3: Remove the Radiator
At this stage, you’re ready to remove the radiator. Carefully unscrew both radiator valves, using your adjustable spanner or wrench, from the connections on either side of the radiator. Be prepared to catch any water that may still be in the pipes. Keep the valve caps or plugs nearby to seal the pipes and prevent any leakage. Gently lift the radiator off the wall and place it aside.
Step 4: Drain Any Residual Water
After removing the radiator, it is likely that some residual water may still be present in the pipes. To prevent any water leakage, use the valve caps or plugs to seal the open connections temporarily. If there is any water remaining, drain it into a suitable container or directly into a sink. Use towels or a sponge to dry the surfaces and prevent any water damage.
Step 5: Reassembly (If Required)
If you plan to reassemble the radiator or replace it with a new one, follow the manufacturer’s instructions for installation. Always ensure that the system is properly sealed and that all connections are secure before turning the boiler back on and restoring the hot water flow to the radiator.
Remember, if you’re unsure about any step or if you encounter any complications, it’s always best to consult a professional heating engineer or plumber for assistance. Removing a radiator incorrectly can cause damage to your heating system or result in water leakage.
By following these step-by-step instructions, you can safely remove a radiator from your combi boiler system and proceed with your maintenance, repairs, or redecoration tasks.
Preparing for radiator removal
Before proceeding with the removal of a radiator in a combi boiler system, it is important to take the necessary preparatory steps. This will ensure that the process goes smoothly and helps to prevent any damage or unnecessary complications. Follow the steps below to properly prepare for radiator removal:
1. Turn off the central heating system
Before starting any work, it is crucial to turn off the central heating system and allow it to cool down. This will help to minimize the risk of any accidents or burns during the removal process. Locate the central heating controls and switch them off according to the manufacturer’s instructions.
2. Gather the necessary tools
Ensure that you have all the tools required for the radiator removal. This may include a radiator key or spanner, adjustable spanner, pipe cutter, and a bucket to catch any water that may leak during the process. Having the right tools on hand will make the removal process easier and more efficient.
By taking these preparatory steps, you can ensure a smooth and efficient radiator removal process on a combi boiler system. Remember to always follow safety precautions and refer to the manufacturer’s instructions for guidance.
Draining the radiator and heating system
Before removing a radiator from a combi boiler system, it’s essential to drain both the radiator and the entire heating system to avoid any accidental leaks or damage. Draining the system is a straightforward process that can be done with the following steps:
- Switch off your central heating system and boiler. Make sure they are completely turned off.
- Locate the isolation valves on your radiator. These are typically found on each end of the radiator where the pipe connects to it. They are usually round and can be turned with either a screwdriver, an adjustable wrench, or by hand.
- Close the lock shield valve on the radiator by turning it clockwise using an adjustable wrench or a flat-head screwdriver. This valve is typically located at the opposite end of the radiator from the isolation valves.
- Now you can open the bleed valve on the radiator to release any excess pressure if it’s present. Use a bleed key or a screwdriver to do this slowly and carefully. It’s advisable to have a container handy to collect any water or debris that may come out during the process.
- Attach a hosepipe or a drainage container to the drain-off valve, which is found at the bottom of the radiator. Open the valve following the manufacturer’s instructions to let the water drain completely out of the radiator and into the container or drainage system.
- Repeat this process for each radiator in your heating system until the water has been drained from all of them.
Following these steps will ensure that your radiator and heating system are properly drained and ready for removal. Remember to take all necessary precautions, such as wearing gloves and using proper tools, to prevent any accidents or injury during the process.
Removing the radiator
Before removing the radiator in a combi boiler system, it’s important to ensure that the heating system is safely turned off and that the boiler is cool. Here are step-by-step instructions:
1. Draining the system
The first step is to drain the heating system. Begin by shutting off the water supply valve and the radiator valve. Then, locate the drain valve, typically found at the lowest point of the system, and attach a hose to it. Place the other end of the hose in a suitable drain or container.
Next, slowly open the drain valve to allow the water to flow out. It’s important to note that the water may be hot, so use caution. Once the water has drained completely, close the drain valve.
2. Disconnecting the radiator
After draining the system, move on to disconnecting the radiator. Start by using a wrench to loosen the nut that connects the inlet pipe to the radiator valve. Place a container or towel underneath to catch any remaining water.
Then, use the wrench to loosen the nut on the outlet pipe. Once both nuts are loose, carefully remove the radiator from the brackets or supports that are holding it in place. Tilt the radiator slightly to ensure any remaining water drains into the container or towel.
Once the radiator is disconnected and drained, you can move it away from the desired location. Be cautious as radiators can be heavy and bulky.
It’s important to note that when removing a radiator, the heating system may need to be repressurized and the water in the system may need to be treated or replaced. It’s best to consult a professional or follow the manufacturer’s guidelines for further advice.
