When the time has arrived to change radiators, it’s imperative to know that your new designer radiator delivers a sufficient heat output for your chosen room. You can be sure that it does by calculating the BTU (British Thermal Units) requirements of the space.
calculations for measuring a radiator
You’ll need to measure the height, width and length of the room your new radiator is to be fitted in, and input these figures along with a few more details to our BTU Calculator.

Wall distance
The gap between the wall and your radiator can be determined as the wall distance. It’s a useful measurement to record as it allows you to calculate how much space will remain behind your radiator once mounted.
Simply measure from the back of your radiator to the wall to assess the size of the gap accurately. And remember to account for extra room if you intend to fit a radiator cover.
Wall to face
For a wall-to-face measurement, you’re working out how far into your chosen room your new radiators will project. The distance is calculated from the furthest point on the face of your radiator to the wall.
Whilst this isn’t an especially crucial aspect of a like-for-like radiator replacement, it is useful if your new radiators or towel rails are being installed in a noticeably compact room with space at a premium.
