What Is BTU?
BTU stands for British Thermal Unit. It’s a calculation of the energy needed to heat 1lb of water at 39-40°F (3.8-4.4°C). In energy terms, this roughly equates to 1.055 kilojoules (kJ); in layman’s terms, it’s more or less the amount of energy it takes to burn a wooden match.
BTU calculations account for the heat required to fill a room as well as the amount of heat loss.
