The process may seem daunting, but with the right tools and some basic knowledge, it can be a straightforward task. In this guide, we’ll take you through the steps of removing a radiator and replacing it with a new one.

Get ready to tackle the task at hand! Before diving into the specifics, let’s take a quick look at the tools and steps you’ll need to be familiar with before you begin. Here’s a handy overview to give you a sense of what’s in store:

To remove your radiator you will need the following tools:

  • A radiator key
  • A large container or bucket
  • A cloth or rag
  • A wrench or adjustable spanner

Here is a brief summary of the steps you need to take:

  • Turn off your heating system and the valves connecting the radiator.
  • Drain the water and open the bleed valve to release air.
  • Loosen the valve at the other end of the radiator.
  • Disconnect the radiator from the wall brackets or mounts.
  • Lift the radiator off the wall brackets or mounts.

Now that you have an idea of what you’ll be working with, you’re ready to get started!

1. Turn Off Your Heating:

The first step in removing your radiator is to turn off your heating. This will prevent hot water from flowing into the radiator while you work, which can be dangerous. Once you have turned off your heating, you can proceed to the next step.

2. Turn Off the Valves:

Next, you need to turn off the valves that connect the radiator to the heating. These valves are typically located at the bottom of the radiator and can be turned off using a wrench.

3. Drain the Water:

Once you have turned off the valves, you need to drain the water from the radiator. To do this, place a bucket under the radiator and open the bleed valve using a radiator key to allow the water to flow out.

4. Open the Bleed Valve:

After draining the water, open the bleed valve to allow air into the radiator. This will make it easier to disconnect the radiator from the wall brackets or mounts.

5. Loosen the Valve:

Next, you need to loosen the valve at the other end of the radiator. This valve is typically located at the top of the radiator and can be loosened using a radiator key, a wrench or an adjustable spanner. If the valve is stuck, you may need to apply some penetrating oil to help loosen it.

6. Disconnect the Radiator:

With the valve loosened, you can now disconnect the radiator from the wall brackets or mounts. Depending on the type of radiator you have, this may involve removing screws or bolts, or releasing clips. Make sure you have a cloth or rag on hand to wipe away any water or debris that may have collected around the radiator.

7. Lift the Radiator:

Finally, you can lift the radiator off the wall brackets or mounts to remove it. Make sure to handle the radiator carefully, as it may be heavy, it may be helpful to have someone assist you in lifting it.
