Key tips for measuring a radiator
How to measure a radiator is certainly among the essentials you need to know before committing to renovating radiators in any room. Ensuring you have noted the correct size of your existing radiator provides the prime foundation for a successful replacement job.
In this guide, we’ll focus on the best practices for correctly measuring your radiators, and ensuring the perfect fit when installing new radiators.
So, how do you accurately measure a radiator?
Let’s get started.
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 standard radiator…
- Measure the width
- Measure the height
- Measure the left pipe centre to the right pipe centre
- Measure the wall-to-pipe centres
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 centre of one pipe to the centre 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 centre measurement.
Calculating wall-to-pipe centres
In calculating the wall-to-pipe centres, you are measuring the distance from the wall where 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.
