BTU Calculator

Our BTU Calculator is designed specifically to save you money and make sure you don’t get too little or too much heat.

It’s super easy to use and tells you how many BTUs your will need when selecting the radiators to make a difference in your home.

Once you have your Minimum and Upper BTU estimates aim to match or exceed it as best you can.

Pick a radiator that you like from our fantastic range and be sure to check out its technical information for the BTUs!


Having the heat and not needing it is much better than needing the heat and not having it!

You can always turn a hot radiator down with one of our Thermostatic Radiator Valves.

There are always a lot of factors to consider when warming a room, so if you would like any assistance feel free to call our team of friendly heating experts.
