BTU Calculator

Below is a tool that can enable you to calculate the BTU requirements needed for your room.

There are many factors that affect this calculation including the outdoor temperature, thickness of exterior walls and the quality of insulation installed. You should also ensure you have a boiler that is capable of generating necessary output for all of the radiators in your property.

Our BTU calculator should be used as a guide only, the actual BTU requirements may be slightly different to what our calculator will produce. If you need further help, please contact us.
