Posted by mprice 30/10/2017 0 Comment(s) Heating,

Our BTU Calculator is here to help you work out the BTU energy requirements of a room, and in so doing help choose appropriate radiators able to comfortably heat this room.


Sounds simple! Well yes it is, but there are many variables, so to get a better understanding of what it all means, we'll try and explain how and why it could help you.


What is BTU?

BTU stands for British Thermal Unit and is a measure of heat output from a radiator.

How can it be used?


This BTU figure gives a simple but accurate guide to your rooms heating requirements. Ultimately this will ensure you have sufficient radiator heat output to keep your room warm and, as importantly, eliminate the expense of any unnecessary radiators.


What does it calculate?


Given the cubic volume of a room (this is the time to get the tape measure out) along with details on the room type, number of windows/doors, external walls etc our calculator will give a BTU value of the radiator/s required to happily heat this room.

How does it work?

The BTU is formulated and will give you a single figure BTU requirement e.g 3000 BTU along with radiator options that match this BTU output.


As an additional bonus, all our radiators have a BTU value listed in their specifications so, given this information, you may decide to have two Single Panel Convector Radiator 530 x 540mm (e.g product code 207121) with a BTU value of 1579 or one larger Double Panel Plus 600 x 700mm Radiator (e.g product code 239722) with a BTU value of 3215.

Product Selector Guide

Our BTU calculator will offer you a variety of different radiators matching your BTU value. They'll be listed by price / range / manufacturer / style so if you're looking to achieve a modernistic or minimalistic look, a contemporary or colourful theme, or just as cheap as you can find, we'll have it listed.

Radiator brands

'So many choices' would probably best sum up shopping for radiators today, but to simplify, it's advisable to use one brand if multiple radiators are being installed. This will ensure continuity through your house and also make installation easier, and generally cheaper.
