Why do we use BTU?

“In the world of HVAC, we measure heat leaving our homes (heat loss) or coming in (heat gain) in BTUs. A BTU is a British Thermal Unit. It’s a unit of measure like a calorie or a joule, but it’s an English unit. Like using yard instead of meter, we use BTU instead of calorie.”

Why is it called British Thermal Unit?

It came from the mind of Thomas Tredgold, a British railroad engineer who dabbled in heating and ventilating public buildings. What’s delightful about that definition, though, is the business about a cubic foot of water rising in temperature by one degree Fahrenheit.

Are higher BTUs better?

A heater with a higher BTU rating is more powerful — that is, it has a higher heat output — than one with a low BTU rating. It can do more to raise the temperature in your room each hour, so you can either heat a room more quickly or heat a larger space.
