Calculating Radiator Pipe Centres

Calculating Pipe Centres & Maximum Width of Radiators

We always advise you to wait for your cast iron radiators to be onsite before working out pipe work and pipe centres widths. This is because cast iron is not an exact product and because each radiator is hand assembled there will always be slight discrepancies as indicated on each radiator page in the lengths of same style & size radiators.

However, we appreciate that occasionally some prep work may need to be carried out prior to your order arriving onsite and that approximate pipe centre measurements may be required for first fix purposes.

Therefore, and strictly as a guide only, we would say for the approximate pipe centres for each cast iron radiator to add approx 90mm/3.5” to the overall length shown on the Specification tab. E.g. if the length indicated for a radiator is approximately 950mm then the approximate pipe centres will 1040mm & so on.

For the approximate measurement off the skirting board or wall if no skirting is used to the Pipe Centre we suggest half the depth of the cast iron radiator + 10mm as a minimum.

For the approximate ‘outside valve to outside valve measurement’ (the minimum measurement to be able to operate the valves freely) you should add approx 150mm/6.0” to the length indicated for each radiator in the Specification tab. E.g. if the length indicated for a radiator is 950mm then the approximate measurement from the outside of one valve to the outside of the opposite valve will be 1100mm.

PLEASE REMEMBER THAT THE ABOVE MEASUREMENTS SHOULD BE USED AS A GUIDE ONLY
