BTU Calculator

BTU stands for British Thermal Unit. It is approximately the amount of energy needed to heat one pound of water by one degree Fahrenheit. It is extremely important to know the exact BTU of the radiator you require to keep your house warm.

It seems to be an extremely tricky balancing act to work out the exact size of radiator you require to keep your house warm at exactly the right temperature and still make sure you do not over-heat the room and waste too much precious energy.

In order to help you with this situation, please take advantage of our easy-to-use BTU Calculator. The BTU Calculator asks some simple questions about the room where you want to install a radiator. When you click the button "Get Total BTUs", it will tell you the output you need to heat the room properly. Once you know the exact number, click on the link that will take you to the radiator selector
