When you are installing a central heating radiator, there are a few things that you will need to keep in mind. Remember that if you are installing one that it will take a little bit more work than if you were just to replace one. If you are ever in doubt on your skill level on this project then you should not hesitate to consult a professional. A radiator is something that can be tricky to deal with. Never do something that you are not comfortable with projects like these.

Step 1 – Room Measurements

The measurements of the room that the radiator is going in matter quite a bit. You will need to know them so that you will be able to know where the best place to set the radiator will be. You will need to multiply the cubic feet of the room volume by five. The result will equal the BTU temperature that is required. It is best to install the furnace in the coldest area of the room. This is typically underneath a window or against an outside wall.

Step 2 – Drain Central Heating System

It is important that the central heating system is completely drained before you begin any work that has to do with your heating.

Step 3 – Fit Valves

Before you hang the radiator, you will first need to get the valves fitted. This will help you to be able to get a good idea from where the pipes will be coming up from your floor. You may need to move your radiator or bend the pipe if the valve is above a joist. Using PTFE tape, you will need to wrap it around the threaded part of the tails of your valves. From there, using your Allen key, screw them into your radiator.

Step 4 – Hang Radiator

In order to hang your radiator, you will need to position the radiator how you want it hung while it is still on the floor. Once you have it in the desired position, take out your pencil and draw on the wall above your radiator. From there, you will need to measure the distance of the brackets.

Step 5 – Drill

Once you have the brackets set up and your wall marked, you will need to then drill a hole that goes into each of the slots. Before you drill, make sure that there aren’t any pipes or cables behind the wall. Once the brackets are properly screwed in, you can hang the radiator.

Step 6 – Pipes

Once the radiator is hung, it is time to move on to the pipes. If these pipes are from the floor, make sure that they are held in line with the positions of your valves. Make sure that the holes are not too small as this will cause the pipes to be noisy. Using a pipe cutter, you will need to joint the pipes. Once you have finished your installation, be sure to let the water back into your expansion tank. Bleed your radiators until you have the pressure at one bar.
