Installing a central heating radiator

Installing a central heating radiator is not an easy job and it should be done by someone who has some basic skills. Call a professional if you need any help. Here are the materials needed:

  • Radiator
  • Room Measurements
  • PTFE Tape
  • Allen Key
  • Pencil
  • Drill
  • Pipe Cutter


You will need to measure the space that you have available for the radiator.

This is important because you will have a lot of pipes and you will need space to work with them. Also because of the heat, the radiator needs to have space around it to avoid any fires. Also calculate how big the radiator needs to be. Multiply the cubic feet of the room volume by five and this is the right BTU required. Also it’s better to install the furnace in the coldest area of your room.


Drain the water from the heating system before working with the radiator and with the pipes.


The valves will need to be fixed before the radiator. This will give you an idea of the position of the pipes and where to install the radiator. Use PTFE tape to wrap it around the threaded part of the tails of the valves.

Hanging the radiator

Position the radiator so that it is near the pipes. Place it one the wall and then draw a few lines to know the position. Determine the position of the brackets and then drill a few holes. Make sure that there aren’t any pipes behind the door. Then place the brackets and the radiator.


If the pipes come from the floor, then make sure that they are held in line with the positions of your valves. The holes need to be big enough to avoid vibrations and noises. Joint the pipes if needed with a pipe cutter. Let the water back into your expansion tank. The pressure needs to be right for the radiator to work.
