To estimate the BTUs needed to heat a 3,300 sq ft house, a general rule of thumb is to use about 30-60 BTUs per square foot, depending on factors like climate, insulation, and ceiling height. This means you would need approximately 99,000 to 198,000 BTUs. A more precise calculation would consider specific factors such as local weather conditions and the home’s energy efficiency. Consulting with a heating professional can provide a more tailored assessment.
