BTU Calculator

A British Thermal Unit (BTU) is a measure of heat output from a radiator. Depending on specific factors of a room such as: it’s size, the insulation, the number of windows in the room and if they’re double glazed or not - with these things in mind you’ll be able to calculate the amount of power needed to heat your room. If you have a higher BTU requirement, you may have to use more than one radiator to deliver the heat you’ll need. Alternatively, the total BTU output of several smaller radiators may meet your needs.

If you find that your radiator remains cool at either the top or the bottom as it is heating up, you may have trapped air within it. To release this air, you’ll have to bleed the radiator. This is a fairly easy job, and requires just a few tools which you should already have. If you find that more than one of your radiators is having the same problem, or that once they’ve been bled they still aren’t working efficiently, it may be a bigger problem. Read step-by-step guide on how to bleed a radiator.
