Newly fitted radiator

Installing a central heating system into your home can be a good way to help cut costs if you are trying to save some cash. Here, in our guide to how to fit a radiator, we give you the information you need to install radiators and decide on the best place to position your radiator so you have the best central heating system possible.

All that being said, if you are ever in doubt about what to do when installing pipework, boilers or radiators in your home, do ask the help of a professional expert. They may well cost more, but that initial outlay could save you a lot of cash in the future should your central heating system break down or leak due to your faulty installation.

Decide on the best place to position your radiator

Deciding the best place to position radiators in your home is key to optimising your central heating system and making it as efficient as possible. Do this first before installing a radiator in a room - or even before buying one. The best position for a radiator in a room, energy efficiency speaking, is the coldest part of the room in question.

However, in terms of where you want to put furniture, this may not always be an option. If you are ever in doubt, putting a radiator beneath a window is a good option as this is often the coldest part of a room and also a place that furniture cannot be put.

Step-by-step guide to installing your radiator

In this section of our guide, we look at how to fit a radiator. As ever, if you are unsure or you want to learn how to fit thermostatic valves, it may be better in the long-run to seek professional help. Thermostatic valves are valves that allow you to adjust the temperature of an individual radiator so that you can make your central heating system more efficient.

Prep

Installing a radiator requires a fairly substantial amount of prep work. Before starting on installation, you need to put PTFE tape on the bottom of your radiator valve. You need to wrap PTFE tape around each valve about 20 times, so make sure you have enough before you start. Once done, take out your radiator's bung.

Then, work on attaching air vents. You need to screw these in, but ensure that they are not screwed in too tightly. Doing so could damage it so it is tricky to use in future. From there, connect your radiator tails so you can still see one of the threads.

Putting a radiator on a wall

Before putting your radiator on the wall, you need to locate exactly where it needs to be. To do so, you need a centre point of the radiator and the wall. Therefore, measure your wall's width and the radiator, and using a pencil, locate where the centre of the radiator needs to be on your wall. From there you then need to find the midpoint between your radiator's brackets.

Once you have the width and a midpoint, you need to find the height of your radiator and where you want it from the base of your wall. Measure the radiator's height and locate how high up you need it to be.

Then, mark where the brackets need to be positioned on the wall to install the radiator at the height and width you need it to be. Drill the wall with a bit where the brackets will go according to your measurements. Then install wall plugs to protect your wall. It is now that you can attach the brackets. Once you have done that, ensure they are level and exactly where you want them to be. You can then hang your radiator.

You may find that you need to adjust the pipework once you have measured out where you want your radiator to be. In such instances, it is possible to do on your own, but it is highly advantageous to ask for the help of a professional. The reason being is that you need to drain the entire system and install pipework that will need soldering, amongst many other procedures to ensure that it can run through your system efficiently and without leaking. It is a big risk to take if you are anything other than very confident in DIY. You can end up damaging the entire ecosystem of your central heating so much that other rooms no longer heat efficiently because of poor pipework to just one radiator.

Fitting a radiator is a perfectly possible task for a competent DIY enthusiast. With the right amount of time dedicated to it, hanging it straight and in the best position is fairly straightforward - albeit time-consuming. It is when it comes to adjusting pipework that things get a bit tricky. You either need to choose a radiator from our selection that already fits with your existing pipework or employ the use of a professional to ensure that you do not make any costly mistakes to your central heating system.
