Our Verdict
This ProCom heater outputs 20,000 BTU and covers 950 sq ft. That puts it well above most electric heaters in raw heating power. Gas heating also costs less per BTU to run than electric.
You get true dual-fuel flexibility. Switch between natural gas and liquid propane without buying a new unit. Propane mode still delivers 18,000 BTU, which is strong coverage.
Safety features have gaps. No overheat protection is listed. The ODS sensor monitors oxygen and shuts the unit down if carbon monoxide builds up.
Controls are basic. You get thermostat cycling but no timer or remote control. You must walk to the unit to make any adjustments.
At $163.49, the price works out to just $0.17 per sq ft of coverage. That is solid value for a high-output gas heater.
What We Like
- Heats up to 950 sq ft with 20,000 BTU output.
- Works on both natural gas and liquid propane for fuel flexibility.
- 99.9% efficient ventless design wastes almost no heat.
- Built-in ODS sensor shuts off the unit if oxygen levels drop too low.
- Assembled in the USA using high-quality parts and materials.
What Could Be Better
- No tip-over protection is listed, unlike many competing heaters.
- No overheat shutoff protection is included.
- No remote control requires you to adjust settings directly at the unit.
- No timer means you cannot schedule heating automatically.
- No oscillation limits how evenly heat spreads across a room.
