The efficiency of all radiators is measured in British Thermal Units (BTU). Enter your room dimensions, for this BTU calculator to calculate the BTU’s required to heat up your room. This will also provide the size of the cast iron radiator that you need. The BTU calculator will give us guidance to the bespoke radiator we can build for you depending on your choice of style and height. This calculator is a good starting point but there may be other varying factors to be considered. Therefore, we advise a consultation in every circumstance. Contact us on 01435 868289 or via email
