Heating Calculator

Use our easy interactive calculator to find the best electric radiator to heat your room.

Electric radiators are an energy-efficient method of heating spaces of all shapes and sizes, in almost any type of building. Our simple calculator helps you to find the best solution for your room – enter your room dimensions, choose the level of insulation your room has and select a thermal zone by mapping the location of your building and finding the corresponding colour on the map. Our calculator will then suggest which of our electric radiator models you should consider browsing.
