Help & Advice
BTU Radiator Calculator
Our BTU (British Thermal Units) calculator will help you to work out the heat requirement for your room, and recommend the number of radiators you will need to comfortably heat it.
What is a BTU?
A British Thermal Unit (BTU) is a measure of heat output from a radiator. Depending on the size of your room, the number and type of windows and what the room is used for, you'll need more or less heat. If you have a higher BTU requirement, it might be better to use more than one radiator to deliver the heat you'll need to a room. The total BTU output of several smaller radiators may meet your needs.
How do I choose the right radiator?
The BTU value of all our radiators is clearly labelled in-store and online, helping you find those which suit your requirements.
