What Are Pipe Centres and How Are They Measured?
Updated: Feb 6
The pipe centre measurement is the distance between the inlet and outlet pipes for the radiator. It is found by measuring from the centre of one pipe to the centre of the other. It is essential to accurately measure the pipe centre to ensure the radiator can be fitted easily. However, the dimensions of the radiator valves must also be factored into the calculation to ensure the distance between the pipes can accommodate the radiator and valves with minimal alteration.
For example, our Ideal valves require an additional 80 mm (40 mm on each side) that must be added to the width. Therefore a 1000mm wide radiator plus 80mm gives a pipe centre measurement of 1080mm.
The information provided with each radiator will state the allowance that must be made within the pipe centre calculation. While quality valves will generally be produced to an accurate size, manufacturing tolerances must be considered. Therefore, it is always recommended that pipework is not adjusted until the new radiator or towel rail and its valves are fitted
