Radiator Sizing Guide

To pick the right radiator you will need to know how much heat the room requires for it to be heated effectively and efficiently. When purchasing a new radiator make sure you check the technical spec for BTU/Watt output.

 

What are BTU's?

BTU's 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.

How do I Calculate the BTU's for my Room?

The adjacent BTU Calculator is an accurate 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)
