Our Verdict
This heater puts out up to 18,000 BTU. It warms 450 square feet of garage or outdoor space fast. No electrical outlet is needed at all.
The ODS system is a key safety feature. It watches oxygen levels in the area. If they drop too low, the heater shuts off on its own.
You get three heat settings to pick from. Choose 6,000, 12,000, or 18,000 BTU to match the size of your space. Lower settings burn less propane and cost less to run.
The 20-pound propane tank is not included with the heater. You need to buy and fill one before you can use it. Propane costs will grow over a full cold season.
This heater is not safe for indoor or living area use. It works best in garages, workshops, or covered outdoor spaces. If you need to heat a room inside, choose an electric option instead.
