Calculating heat requirements

When considering new radiators, it is necessary to calculate the heat requirements of your space and our handy calculator allows you to do this very quickly. This is really important to ensure you get the most out of your radiators, without overspending on heating bills.

By inputting data about your space including window size, wall materials and room dimensions into our BTU calculator, you will get a guide figure for the output required to efficiently heat your room. This figure may be achieved by combining more than one product in a room
