What is the room calculator and how do you use it?

To help you find the best heater for your room, we have created an easy-to-use Room Calculator.

Electric Heater Room Size Calculator

Before you begin, you will need 3 measurements:

  • The width (in metres) of the room
  • Length (in metres) of the room; and
  • Total length (in metres) of the outside wall

You will also need the desired temperature for the room (18 °C or 21 °C).

After clicking 'Calculate' you will be given a selection of both direct (radiators and panel heaters) and indirect (storage heaters) heating solutions for your room.
