Our Verdict
This Craftsman heater puts out 80,000 BTU/hr. That heats 2,000 sq ft. No standard home space heater comes close to that output.
It runs on six fuel types with no conversion. Kerosene, diesel, Jet-A, and JP-8 all work. That flexibility matters on a job site where fuel availability varies.
The digital LED thermostat and overheat shut-off add useful control. The photo cad cell flame sensor adds another safety layer. But there is no tip-over protection, which is a gap most buyers should note.
Fuel costs are the biggest ongoing expense. At full output, this unit can burn nearly a gallon of kerosene per hour. Budget for that before you buy.
This heater fits one specific job well: large outdoor or construction-site heating. For garages, workshops, or job sites, it delivers real performance. For home or office use, it is the wrong tool entirely.
What We Like
- Delivers 80,000 BTU/hr to heat spaces up to 2,000 sq ft.
- Runs on 6 fuel types including kerosene, diesel 1 and 2, fuel oil, Jet-A, and JP-8 with no conversion needed.
- Digital LED thermostat gives you precise temperature control.
- High-temperature safety shut-off switch activates automatically if the unit overheats.
- Photo cad cell flame sensor shuts the heater down if the flame goes out.
What Could Be Better
- No tip-over protection, a safety feature found on most competing portable heaters.
- No timer, so you cannot schedule heating cycles automatically.
- No remote control, requiring manual operation directly at the unit.
- Burns liquid fuel with high ongoing costs. Running 80,000 BTU at roughly 0.9 gallons per hour adds up fast.
- Outdoor-only rating means you cannot use it in enclosed residential spaces like finished garages or basements.
