Sizing Your Frost Fighter Heater

Choose the right BTU output for efficient, safe heat on-site:

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

Example: A 2,000 sq. ft. site × 50 BTU = 100,000 BTU
→ Use a model like the IDH200QR (170,000 BTU/h) for reserve power.

✔ Consider insulation, temperature gap, and air changes.
