Our Verdict
This heater delivers 70,000 BTU of radiant heat. It covers up to 1,750 square feet. That is far beyond what any standard electric heater can match.
Fuel flexibility is a real jobsite advantage. It runs on kerosene, JP8, both grades of diesel, and both grades of fuel oil. You are rarely stuck without a usable fuel option.
The safety profile has serious gaps. Tip-over protection and overheat shutoff are both missing. Most heaters at this price point include both features.
The onboard thermostat and LED display give you precise temperature control. But you must walk to the unit to make any changes. No remote or timer comes with this heater.
This unit belongs in garages, warehouses, and open job sites. Ventilation is required at all times for kerosene operation. It is not designed for sealed home living spaces.
What We Like
- Puts out 70,000 BTU and heats up to 1,750 square feet.
- Runs on five fuel types: kerosene, JP8, diesel #1 and #2, and fuel oil #1 and #2.
- Onboard thermostat with LED display lets you set exact temperatures.
- Quiet Burner Technology keeps noise low for a heater this powerful.
- Built-in fuel gauge and external filter make refueling and upkeep easy.
What Could Be Better
- No tip-over protection, a standard safety feature on most competing heaters.
- No overheat shutoff, which most electric and propane heaters at this price include.
- No timer to schedule or automate heating cycles.
- No remote control means you must walk to the unit for every adjustment.
- Kerosene fuel costs add up fast at full 70,000 BTU output, unlike electric models with fixed kilowatt rates.
