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.

Step 1: Which room you are heating?
Step 2: What are the dimensions of the rooms?
Are you measuring in metres or feet?:

Rated 4 out of 5 by from This is NOT a thermostat!
Date published: 2013-01-09
Rated 4 out of 5 by from Good product Bought to replace a 20 year old Honeywell theromstat/timer. All the screw holes in the wall for the old one matched precisely to this one and so it was a five minute job to install. Instructions are OK. Lots of flexibility to programme options day by day. Useful as we have a lie in at the weekend. Also has a handy copy function for copying settings for one day to another. 4 stars not 5 as it is a little bit expensive for what it is (a clock and a thermostat) and the click when the themostat triggers is a little loud. However, all in all, not disappointed with it at all.
