BTU Calculator - Find the Right Radiator

Using our proprietary British Thermal Unit (BTU) output calculator, you can accurately determine the amount of energy required to heat your home, by purchasing and installing the right sized radiator and/or towel radiator.

 

  • To produce an accurate, reliable result, our BTU heating calculator is designed to consider the size and dimensions of each room, the type of room or function, the number of outside walls and whether a room contains single or double glazed windows.

Now that you've calculated your required BTU, take a look at our range of compact radiators, designer radiators & heated towel rails.
