What Is Heating BTU Per Square Foot?

Heating BTU per square foot refers to the amount of British Thermal Units required to heat or cool an indoor space. The number varies based upon the specific state of the area, including its insulation, climate, sun exposure and room capacity.

For example, a home in a cool climate may require between 50 to 60 BTUs per square foot, a home in a medium climate may need between 40 to 45 BTUs per square foot, and a house in a warm climate may require between 30 to 35 BTUs per square foot. Poorly insulated areas require more BTUs per square foot than well-insulated areas.
