Our Verdict

This heater puts out 125,000 BTUs. It heats up to 3,200 square feet in about 5 minutes. That makes it one of the most powerful portable propane heaters available.

The smart thermostat turns the heater on and off between 25 and 95 degrees. This keeps your workspace at the right temperature without wasting propane. You connect it to any 20-pound or larger propane tank.

This heater does not have a timer or remote control. You must walk up to it to make changes. These features are common on competing models at this price point.

At $219.99, you pay only $0.07 per square foot of coverage. No standard electric heater covers 3,200 sq ft at this price. The value is strong for garage and workshop use.
