- Enter the length, width, and height of the space you want to heat.
- Select the insulation R-value.
- Choose your preferred unit of measurement.
- Click ‘Calculate’ to see your results.
Formula & Methodology
The BTU calculator uses the following formula to calculate heat requirements:
BTU = (Length x Width x Height x Temperature Difference) / Insulation R-value
Real-World Examples
Example 1: A Well-Insulated Home
A home with dimensions 30ft x 40ft x 8ft, R-25 insulation, and a temperature difference of 20°F requires 12,000 BTU.
Example 2: A Commercial Space
A commercial space with dimensions 50ft x 60ft x 10ft, R-19 insulation, and a temperature difference of 15°F requires 45,000 BTU.
Example 3: A Garage
A garage with dimensions 20ft x 24ft x 8ft, R-13 insulation, and a temperature difference of 25°F requires 7,200 BTU.
