A Comprehensive Guide On How To Remove A Radiator

If you're considering removing your radiator for various reasons, whether it's for decorating, addressing a leak, changing its location, or upgrading to a new one, this step-by-step guide on how to remove a radiator, is here to assist you.

Follow these instructions carefully to ensure a smooth and safe removal process, allowing you to tackle the task confidently without needing professional assistance.

Radiators form a major part of the heating system, and problems with radiators might cause a big issue.

When is the Ideal Time to Remove a Radiator?

Before you embark on the task of removing your radiator, it's crucial to consider the optimal time for home maintenance or renovations. While the average temperature in the UK hovers around 10ºC, winter temperatures can plummet to freezing levels of 0ºC-5ºC. Undertaking the removal of your heating system during the winter may not be in your best interest.

To ensure a more comfortable experience, plan your radiator replacements or renovations thoughtfully. Opt for the summer months when the weather is warmer, and you won't miss the comforting warmth provided by your radiator.

This strategic timing not only makes the removal process more convenient but also ensures that you won't be left without essential heating during colder periods.

Timing is key when it comes to home maintenance, so plan your radiator removals accordingly for a smoother and more comfortable transition.

Tools You Need For Removing a Radiator:

  • Pair of gloves: You will need to protect your hands during the removal process. The radiator is sure to be dirty and might still be warm.
  • Adjustable spanner: Necessary for turning valves and disconnecting the radiator.
  • Radiator key: Used to open the bleed valve and release excess water.
  • Towels: Place towels strategically to catch water and prevent spills.
  • Plastic or metal bowl: A container to collect drained water during the removal process.

How To Remove a Radiator - The Process

In this comprehensive guide, we will walk you through the meticulous steps of removing a radiator, ensuring a smooth and safe process from start to finish. Beginning with the critical initial steps of turning off your heating system and assessing its condition, we prioritize your safety and the efficiency of the removal procedure.

As we progress, each step is outlined with precision, including turning off valves, draining water strategically, and opening bleed valves to facilitate a controlled removal. The symmetrical approach to addressing both sides of the radiator ensures a balanced drainage process, setting the stage for the final step of disconnecting the radiator entirely.

Following this step-by-step guide, you can confidently and successfully remove your radiator, whether for maintenance, repairs, or an upgrade.

Step 1: Turn off your heating

Commence the radiator removal process by shutting down your central heating system. Ensure that both the heating and radiator are turned off completely. This preliminary step is crucial for your safety and the efficiency of the removal procedure. By turning off the heating, you not only eliminate the risk of potential burns from hot water but also create a safer environment for the subsequent steps.

While the system is powering down, take a moment to assess the overall condition of your heating system. Look for any signs of wear, leaks, or irregularities that might require attention during the removal process. This proactive evaluation sets the stage for a more thorough and effective radiator removal.

Allow the system to cool down gradually, ensuring that the temperature has reached a safe level before proceeding to the next steps. This precautionary measure not only safeguards you from potential burns but also makes the removal process more manageable and trouble-free.

Step 2: Turn off the valve

After successfully turning off your central heating system, the next crucial step involves managing the valves on either side of your radiator. Here's a detailed guide on how to execute this phase:

Locate the Valves: Positioned on both sides of your radiator, these valves control the flow of hot water. Familiarise yourself with their positions before proceeding.

Thermostatic Radiator Valve: Begin by turning the thermostatic radiator valve head to zero. This action prevents the flow of hot water into the radiator, contributing to a controlled and safe removal process.

Shield Valve: Now, focus on the lock Shield Valve. Use a wrench to locate the spindle and turn it clockwise until it is completely closed. Take note of the number of turns made during this process. This information will be valuable when reconnecting or replacing the radiator in the future.

Turning off these valves effectively isolates the radiator from the heating system, minimising the risk of water spillage and ensuring a more straightforward removal. This step not only safeguards your surroundings from potential water leaks but also prepares the radiator for the subsequent phases of the removal process.

Step 3: Drain water from the radiator

Lay a towel on the floor beneath the radiator to minimise potential mess. Set up a bowl strategically to catch the water that will be drained during this step. Utilise a wrench to loosen the nut connecting the radiator to the valve. Allow the water to drain out seamlessly.

Executing this step ensures that excess water is contained, preventing spills and minimising the risk of any water damage. The towel and bowl act as practical tools in maintaining a clean and controlled workspace during the drainage process. Once the nut is loosened, the water will flow into the bowl, facilitating a smooth and hassle-free removal of the radiator.

Step 4: Open the bleed valve with precision

Continuing with the radiator removal process, the next step involves addressing excess water.

Follow these concise steps:

Attach the radiator key: Securely attach the radiator key to the bleed valve. The bleed valve is typically located at the top of the radiator.
Turn anti-clockwise: With the radiator key in place, turn it anti-clockwise. This action releases air and excess water trapped in the radiator, facilitating a smoother removal.

By opening the bleed valve, you ensure that any remaining water is efficiently drained, reducing the weight and potential mess during the removal. This step is crucial for maintaining a controlled and tidy workspace, making the overall process more manageable.

Step 5: Loosen the other valve

Maintain symmetry in the removal process by addressing the other side of the radiator with the same precision:

Loosen the connecting nut: Move to the opposite side of the radiator and, using a wrench, loosen the connecting nut between the radiator and the valve. This step allows water to drain from the other end.

Open the Bleed Valve: Similar to the previous side, open the bleed valve on this side. This action ensures that any remaining water is released, contributing to a more balanced and thorough drainage.

By consistently applying these steps on both sides, you ensure an even removal of water from the radiator. This balance not only streamlines the process but also minimises potential complications during the final stages of disconnecting the radiator.

Step 6: Disconnect The Radiator

Loosen all nuts and disconnect the radiator entirely. Lift the radiator off the brackets, ensuring all water is drained. Carefully remove it from the wall, placing it on its side.


Following these steps empowers you to remove your radiator independently. However, if you encounter difficulties, it's advisable to seek professional assistance. With many years of experience, our team is dedicated to ensuring your home's comfort and safety.
