Accurately calculating your BTU needs will help you:
Ensure your space stays warm and efficient with the right radiator size. Here’s how to find the perfect fit for your needs:
Calculate Your BTU Requirements:
We recommend selecting a radiator that is within 10% of your calculated BTU requirement. If you’re choosing between a slightly smaller or larger radiator, opt for the larger size. It’s easier to adjust a bigger radiator’s heat output than to deal with one that’s too small to heat your room effectively.

BTUs, or British Thermal Units, measure radiator efficiency. To determine your radiator’s needs, consider room size, window dimensions, and wall materials. Use our BTU Calculator to get an accurate measure of the heat required for your space. Simply enter your room details, and we’ll show you the BTU output needed for optimal warmth.
For the most precise calculation, consult with a plumber. However, our BTU Calculator provides a good estimate of the required heat output. The figure represents the combined output needed for all radiators and towel rails in your room, as larger spaces may need more than one unit.
A BTU, or British Thermal Unit, is the amount of energy required to heat 1 pound of water by 1°F. Essentially, one BTU is comparable to the heat produced by burning a single wooden match.
We calculate the BTU requirement based on your room’s volume—height, length, and width—plus factors like adjacent spaces. Our calculator provides an estimate of the heat output needed to maintain a comfortable temperature and keep fuel costs manageable.
Choosing the correct BTU output is crucial. A radiator with too low a BTU will leave your room cold, while one with too high a BTU might lead to higher heating bills. Remember, you can always adjust a radiator’s heat output, and combining multiple radiators is an option for achieving the desired BTU level.
