How many BTU to heat a 3200 sq ft home?

To estimate the BTUs required to heat a 3,200 sq ft home, a common rule of thumb is to use about 30 to 60 BTUs per square foot, depending on factors like climate, insulation, and home design. Therefore, you would need approximately 96,000 to 192,000 BTUs for the entire space. It's essential to consider specific factors like local weather, insulation quality, and the home's layout for a more accurate calculation. Consulting with a heating professional for a detailed assessment is recommended.
