Measuring a Radiator in 4 Simple Steps

We’ll get into more detail later, but you won’t go far wrong following these four basic steps to measure a radiator…

Calculating Radiator Width

Very simple. Just take your tape measure across the furthest point of your radiator from one side to the other to gain an accurate measurement of radiator width.

Calculating Radiator Height

Another easy one. Just use a tape measure from the foot of the radiator to its highest point to calculate radiator height.

Calculating Pipe Centres

The distance between the pair of pipe inlets on a radiator represents what we know as radiator pipe centres. To calculate their size, you should measure from the center of one pipe to the center of the other. Just use a tape measure from the middle of the left inlet to the middle of the right inlet to record an accurate pipe center measurement.

Calculating Wall to Pipe Centres

In calculating the wall to pipe centres, you are measuring the distance from the wall that your radiator’s pipe inlets sit as they enter the radiator valves. For an accurate reading, you should measure from the middle of your pipe inlet to the wall. The result will give an indication as to how far away from the wall your pipework is situated, and is extremely useful in helping you avoid invasive plumbing alterations when you decide to swap radiators.

BTU Calculations

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.

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.

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.
