How many btu's are needed for a 1200 square feet?

To determine the BTUs needed for a 1,200 square foot space, a general rule of thumb is to allocate about 20 BTUs per square foot. Therefore, you would need approximately 24,000 BTUs for adequate heating or cooling. However, this can vary based on factors such as ceiling height, insulation quality, climate, and the number of occupants. It's advisable to consult a professional for a more precise calculation tailored to specific conditions.
