How to install a column radiator

Installing a column radiator is quite a simple process. All you need to do is make sure you have the right equipment for the job and follow these easy steps and you’ll have a radiator fitted in no time.

First of all you’ll need the equipment to install your column radiator. Before doing anything, make sure you have:

  • An electric drill
  • A spirit level
  • A tape measure
  • The appropriate wall fixings and drill bits for your radiator
  • The wall brackets that should be included with the radiator
  • If it’s a large column radiator, someone to help you install it
  • A pencil and some paper
  • An adjustable spanner

Once you have everything give your radiator a quick check to see if it has not been damaged on delivery. Then make sure the radiator fits into the space you have selected for it and that there is a boiler feed for the radiator to link to (were the radiator attaches to your central heating system).

Step One

First of all, turn your central heating off and let it cool down for half an hour. Once this is done find the brackets which came with the radiator and place the number needed for the bottom of that particular model on to the bottom of the radiator. Measure the distance between the centre of these two brackets (there should be a hole in the centre of the brackets for a screw) and mark it down on some paper.

After you’ve done this, measure the distance from the middle of the top horizontal pipe to the middle of the bottom horizontal pipe and note this down too. This will be where you want the brackets holding the top part of your radiator to be.

Step Two

Now you know where your brackets are going to go, now it’s time to decide where on the wall you want your radiator. To do this, measure the distance from the floor to the height you want your radiator to be then add the distance from the bottom of your radiator to the middle of the bottom horizontal pipe. Note this down too. This will be how far up from the floor the bottom brackets need to be placed. Alternatively you can measure the height of the feed-in pipes, if they cannot be changed, and note this down.

With this measured and jotted down, make sure you line up the in-put valves of the radiator with the feed-in pipes and measure and note down the distance between where the bottom brackets will be and the feed-in pipes.

Step Three

Get your pencil and your spirit level. Using the measurements you’ve just taken, mark out where the centre of the bottom bracket nearest the primary feed-in pipe (the one which will be attached to your radiator’s control valve) should go, using the spirit level as a ruler.

Then, using the measurement you took for the top brackets mark the distance above the bottom bracket marking you’ve just made. With this mark made, use the distance between the two brackets to mark the other top bracket, parallel to the one you’ve just marked. After this simply use the measurement between the top and bottom brackets to mark your final bracket at the bottom. Make sure that this last mark is the same distance from the first mark as your horizontal measurement between the brackets.

Step Four

Now you’re read to fit the brackets. Taking your first bottom bracket, an appropriate fitting for the bracket to hold it place and your electric drill, line up the centre hole on the bracket with the cross of the first marking you made. When you’re happy where the bracket is going to go, remove the bracket and carefully drill a hole in the centre of the mark you have made.

With this done, line up the bracket hole again, however, this time with the hole you have made. Then drill in the fitting, using the appropriate drill bit, through the hole until the bracket is firmly in place and does not move. With the bracket fitted, use the spirit level to make sure it is straight and flat.

Now all you have to do is repeat this process with all the other brackets, making sure to constantly check the level of them with your spirit level so they are not skewed.

Step Five

Now, preferably with a helping hand if your radiator is particularly large, begin to place your radiator onto the brackets. If your measurements where correct and accurate then the radiator should be entirely square with the wall and not lean to one side or not be able to attach to one of the brackets.

The in-put valves should also line up nicely with your central heating’s feed-in pipes allowing you to simply screw your chosen radiator valve and lock shield valve in place with the adjustable spanner. If there are any gaps then this can be fixed with copper piping measured to fill the gap between the valve and the feed-in.

Step Six

Once the radiator is fitter to the wall and the valves are securely fixed in place you can then turn on your central heating and test the radiator.
