How to Size a Heater

To size a heater correctly, start by measuring the square footage of the area you need to heat. Multiply this by the BTU requirement per square foot based on your conditions:

• Well-insulated indoor spaces: 25–30 BTU/sq. ft.
• Typical job sites: 40–60 BTU/sq. ft.
• Drafty or exposed areas: 60–80 BTU/sq. ft.
• Concrete curing: 50–75 BTU/sq. ft.

Choose a heater with a slightly higher BTU rating to ensure reliable performance in all conditions.
