Is 180,000 BTU enough for my garage?

It suits large spaces, roughly a big multi-car garage, barn or open workshop. For a small single-car garage it is far more heat than you need and will cycle on and off.

Can I use it indoors in a house?

No. It is a combustion heater that produces exhaust and needs fresh air, so use it only in well-ventilated spaces like garages, shops and sites, never in sealed living areas.

Does it run on diesel or only kerosene?

It is designed for kerosene, which burns cleaner and smells less. Some owners use diesel in similar heaters, but that increases odor and soot, so stick with clean kerosene.

How does it compare with a smaller torpedo heater?

It delivers much more heat than 50,000–75,000 BTU models, so it heats bigger volumes faster but uses more fuel and is heavier to move. Choose it only if your space is genuinely large.

Does the thermostat turn the burner off?

Yes. The thermostat cycles the heater to hold your set temperature, and the automatic shut-off cuts the unit if it overheats or flames out.

What maintenance does it need?

Keep the tank and fuel clean, replace the filter as needed, and check the spark plug and nozzle over time. Store it dry and run it regularly in season.
