Sizing a radiator or towel warmer for a bathroom is not as easy as just putting in what was already there, as many are now more efficient than they were in the past.

 

Often therefore, it pays to recalculate your heat requirements so that you are not overheating a room with a radiator with too high an output and using more energy than is required; or underheating a room with a radiator with insufficient output.

 

Using this calculator, you will be able to estimate your BTU heat requirements, helping you find the perfect radiator or towel-warmer for your room.
