Our Verdict
This ProCom heater puts out 30,000 BTU with no electricity required. It covers up to 1,400 square feet. That is roughly five times the coverage of a typical electric space heater.
You ignite it with a push-button Piezo system and pick from three heat levels. The Oxygen Depletion Sensor shuts the unit off if indoor air becomes unsafe. That is a critical protection feature for any indoor propane heater.
The heater has no thermostat, no timer, and no remote control. Every adjustment requires walking to the unit. Competing electric heaters at this price point almost always include these controls.
Tip-over protection is absent. Place this unit on a flat, stable surface well away from children and pets. Propane heaters carry higher placement risks than electric alternatives.
At $189.99, your cost per square foot of coverage is just $0.14. That is an excellent number for large-space heating. For garages, workshops, or off-grid spaces, this heater delivers strong performance per dollar.
What We Like
- Puts out 30,000 BTU and heats up to 1,400 square feet.
- Runs entirely on propane. No electricity needed, even during power outages.
- Oxygen Depletion Sensor shuts the heater off automatically when indoor oxygen drops too low.
- Comes with both base feet and a wall mounting bracket for flexible installation.
- Three heat settings let you choose low, medium, or high output as needed.
What Could Be Better
- No tip-over protection. The heater stays on even if it falls over.
- No thermostat. You cannot set a target room temperature to maintain.
- No timer. You must manually turn the heater off every time you use it.
- No remote control. You must walk to the unit to change any setting.
- Blower fan not included. You must purchase it separately to circulate heat across the room.
