BTU Calculator

Sizing a radiator for a room is not as easy as just putting in what was already there, radiators are now more efficient than they were in past years.

As such, rooms need to be re-calculated so that you are not over heating a room with a radiator of too much output and therefore using more energy than is required; or under heating a room with a radiator with insufficient output, may never raise the temperature to that required!

Using the calculator below, you will be able to accurately size your radiators and then find the ideal size for you room.
