A lot of DIY hobbyists enjoy completing their own routine maintenance tasks in and around their homes, which is perfectly normal. However, there are a few tasks that are considered a little trickier than others, no matter how simple they may seem.

I’ve completed a lot of boiler installations over the years and almost all of them result in a new radiator being fitted or an existing one being relocated. Some customers prefer to relocate them themselves in an effort to save money – not a problem, only if you know what you’re doing.

How to relocate a radiator

Failing to follow the basic steps of plumbing when you relocate a double convector radiator can become quite serious. You could potentially damage the heating system, damage pipework or even blood the room that you’re trying to move from.

Fortunately, I’m going to talk you through relocating a radiator correctly at home so you don’t fall victim to a domestic plumbing disaster.

Measure the radiator and its new location

Before you can get into the exciting plumbing aspects of the relocation, there are a few basic things that you simply must complete first. Number one being measuring the radiator in its current position before you remove it.

You need to know how much space you’re going to need on the new wall when it comes to fitting. Remember to measure the space between the bottom of the radiator and the floor to allow for the pipework running to and from it.

If you’re not confident in your abilities to estimate the amount of new pipework needed then you’re best bet would be to consult with a plumber who will be able to provide you with a more accurate estimate.

Drain down the heating system

Before you can start ripping radiators off of walls, you’ll need to drain the heating system of any water or you could find yourself flooding the place and causing a lot of damages. Before you can start draining, you’ll need to turn off the boiler and isolate the electricity supply.

If you try to drain the system with the electricity supply still running, you could find that the boiler fires back up or the pump may start which could lead to it burning out and overheating the boiler.

If you’re planning on doing all of this work yourself, then you’ll need to have a basic understanding of plumbing and heating systems. Otherwise you could find yourself causing more harm than good.

Radiator Installation

Capping the pipework

When you’re satisfied that the radiator is empty and the system has been completely drained down you can start to cap the pipework and prepare the radiator for moving.

A lot of plumbers will use a push-fit cap to cap off the existing pipework however; we prefer to use the soldering method as it provides a more secure capping method. Once the pipework has been removed you can open up the TRV’s to ensure that any remaining water is removed from the radiator.

Installing the new radiator

When it comes to fitting the new radiator onto the wall, you should have already made the required measurements, allowing for the pipework in the process. Make sure that you use the wall fixtures from the original radiator when fitting it.

If you try to use a different set, it may have different screws and fitting spots, which couldn’t fit. Without the correct fitting parts, you wont be able to hang the radiator onto the wall.

Make sure that the TRV’s have been closed and the pipework has been correctly fitted and secured before proceeding to refilling the system.

Refill the system and switch the boiler on

After all of the necessary pipework adjustments you can start to refill the system. Again, you will need a basic understanding of plumbing to do this properly. If you’re not sure, consult a local plumber as they complete hundreds of boiler installations in Milton Keynes each year.

When the system has been refilled you can turn the electricity supply back on and test the new radiator. Make sure that the boiler is able to reach the correct pressure. If it isn’t, you’ll need to get a registered gas engineer to take a look and fault find on your behalf.
