Need to know what size radiator you need?

Choosing the correct radiator can help reduce your energy bills. A radiator that is too large may increase your bills unnecessarily, and a radiator that is too small will not provide enough heat and will be constantly running at it's maximum. By using our BTU Heat Loss calculator below, you can work out the Watt / BTU outputs required for a particular room. This will ensure that your room(s) will be heated comfortably and efficiently.

Some electrical heating manufacturers will prefer to list their products in terms of BTU, so we have converted watts into BTUs here
