BTU Calculator
Other Factors:
- Sunlight: If the room is sunny, increase the BTUs by 10%.
- Occupancy: Add 600 BTUs for each additional person beyond the first two people.
- Appliances: Add extra BTUs for heat-generating appliances in the room (e.g., 400 BTUs for a stove).
The BTU calculation typically focuses on the floor area (length × width) rather than the room’s height because most residential and commercial spaces have a standard ceiling height, usually ranging from 8 to 10 feet.
