How do I choose the right radiator?
BTUs are ‘British Thermal Units’, the unit in which radiator efficiency is measured. Factors such as room dimensions, window size and wall material are used to calculate the required outputs of radiators, in order to adequately heat a room.
Use our BTU Calculator to determine the heat requirements of your room. Simply enter the details in the corresponding fields and we’ll show you how many BTUs you need to ensure your space is always warm, cosy and inviting.
How do I calculate the BTUs for my room?
The best way to get an accurate calculation is to enlist the services of a plumber. However, BestHeating's BTU calculator is a good guide as to what level of BTU and Watt output will efficiently heat your room. Please note: the calculated figure is for the combined heat output of all radiators and/or towel rails in your room (larger rooms may require more than one).
