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?

Rated 5 out of 5 by from Fernox Leak Sealer My central heating system sprung a leak from a pipe/Union sealed in a concrete floor one week before setting off on holiday. I added Fernox Leak Sealer via the header tank after emptying the tank and draining a bucket of water from the system - to ensure the sealer was drawn in to the system. I then ran the heating for a few hours to mix through system. Following morning all dry, no more leak! The sealer has appearance and consistency of PVA glue so was too gluppy to add via a radiator. There is a version of this sealer for adding via radiator but it's much more expensive. This product did exactly what it promised to do and saved a huge amount of hassle.
