Heat Coverage Formula:
From: | To: |
Definition: This calculator estimates the heat requirement for a garage space based on area and BTU per square foot.
Purpose: It helps determine if an 80,000 BTU heater is sufficient for your garage space or if additional heating is needed.
The calculator uses the formula:
Where:
Explanation: The area is multiplied by the BTU requirement per square foot to determine total heating needs.
Details: Accurate calculations ensure efficient heating, proper equipment sizing, and energy cost savings.
Tips: Enter the garage area in square feet and BTU per square foot (default 20 BTU/h·ft² for garages). All values must be > 0.
Q1: Is 80,000 BTU sufficient for my garage?
A: This depends on your garage size. An 80,000 BTU heater typically covers 1,600-2,000 sq ft in moderate climates.
Q2: What's a typical BTU/ft² for garages?
A: Most garages need 20-30 BTU/h·ft², but this varies by insulation, climate, and desired temperature.
Q3: When would I increase the BTU/ft²?
A: Increase for poor insulation, extremely cold climates, or if you want to heat the space quickly.
Q4: How do I measure my garage area?
A: Multiply length by width of your garage. Don't forget to account for ceiling height if over 8 feet.
Q5: Does this include heat loss factors?
A: The BTU/ft² should account for typical heat loss. For precise calculations, consult an HVAC professional.
