Our Verdict

This heater puts out 30,000 BTU and covers up to 750 sq ft. That puts it among the most powerful home propane heaters available. It handles large rooms with ease.

You do not need an electrical outlet to run it. It works on propane alone. This makes it useful during power outages or in detached garages.

A built-in thermostat adjusts the heat automatically. An oxygen depletion sensor shuts the heater off if air quality drops. Both features improve safety for indoor propane use.

The blower fan kit is sold separately. You must budget extra if you want forced air circulation. The base unit uses radiant heat only.

This heater has no tip-over protection. Place it on a stable, level surface away from foot traffic. It fits best in garages, workshops, and large open rooms.
