Our take on the Mr. Heater 210,000 BTU Forced Air Kerosene Heater

The Mr. Heater 210,000 BTU Forced Air Kerosene Heater is a job-site torpedo heater built to warm large open spaces such as garages, workshops and construction sites. Its high-output fan pushes heated air across up to 5,250 square feet, and a thermostat cycles the burner to hold a set temperature. It runs on kerosene, needs electricity for the fan and ignition, and must be used in well-ventilated or outdoor areas because it vents combustion gases into the space. Against smaller 35,000 to 80,000 BTU torpedo heaters it trades portability and fuel economy for far more raw output, and it competes with propane forced-air heaters that avoid liquid fuel handling but need gas cylinders.

Questions and answers

What size space can it heat?
Mr. Heater rates it for up to about 5,250 square feet. Real-world coverage depends on ceiling height, insulation and outdoor temperature, so treat that figure as a best case.
Does it need electricity?
Yes. The fan and ignition run on electricity, so you need a power source near where you use it. It does not run on kerosene alone.
Can I use it indoors?
Only in well-ventilated areas such as a garage with open doors or windows, or outdoors. It vents combustion gases into the space, so sealed rooms are unsafe.
Kerosene or diesel?
Kerosene is the specified fuel and burns cleaner with less odor. Diesel or kerosene substitutes can work but typically smell worse and may shorten the life of the wick and burner.
Does the thermostat turn it on and off automatically?
Yes. The thermostat cycles the burner to hold your set temperature, and high-limit and flame-failure sensors shut it down if something goes wrong.
How is it moved?
It is freestanding on rubber tires with tubular steel handles, so one person can roll it, though at about 70 lb it is not a carry-around unit.
