We compared four propane heaters on what each listing states: output, coverage, thermostat control, safety features and warranty terms.

How the points were given

The Shop Score weighs performance, build, value, safety and warranty. For heaters, safety means a stated certification such as ANSI, plus tip-over, overheat or ODS protection the listing names; only the ProCom states a certification here. Two of the four listings state a warranty term, both 1 Year Limited. How We Pick explains the weights.

Product Shop Score Perf. /35 Build /25 Value /25 Safety /10 Warranty /5
ProCom ML300TBA-B 9.6 30 21 20 8 1
Mr. Heater MHC125FAV 9.5 32 20 20 0 1

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.

What the listings tell you

We compared four propane heater listings. Two state a warranty term and one states a safety certification, while the two title-only listings state no specs beyond the title. Only one listing states thermostat control: the ProCom, with High, Medium and Low settings. The other three state no thermostat control, so a garage owner who wants the heater to hold a setting has one pick with that feature stated.

Buying guide: the best propane heater for garage with thermostat

BTU and coverage

Match the stated BTU and coverage to the space. The ProCom states 28,000 BTU for up to 1400 sq. ft., the Mr. Heater forced air heater states 125,000 BTU for up to 3,125 square feet, and the Remington states 60,000 BTU for up to 1500 square feet. The Buddy states 9,000 BTU with no coverage figure. A bigger BTU figure does not help if the listing gives no coverage figure to match it against.

Thermostat control

Only the ProCom states thermostat control, with High, Medium and Low settings. The Mr. Heater forced air heater, the Remington and the Buddy state no thermostat control in their listings. If the heater must hold a setting while you work, that leaves the ProCom as the only pick with the feature stated.

Ventless vs forced air

The ProCom is a ventless blue flame heater that needs no electricity, so it runs during a power outage. The Mr. Heater and the Remington are forced air heaters, and the Mr. Heater listing places them in well ventilated construction sites, barns, warehouses and workshops. The Buddy is a radiant heater. Never run an unvented heater in a closed garage: follow the maker guidance on ventilation and keep a carbon monoxide alarm in the garage.

Hoses, mounting and power

Check what comes with the heater before the first job. The ProCom includes wall mount hardware and base feet, so it mounts on a wall or stands on the floor. The Mr. Heater forced air heater includes a 10 ft. hose and regulator. The Remington states the tank is not included, so plan on a separate propane tank. The Buddy states no hose, mount or tank details, so treat those as unstated.

For a plug-in option instead of propane, see the best electric garage heater guide.

Garage Fit Check

  • Measure the space first: the ProCom lists 8.0 by 29.0 by 28.0 inches, and the Mr. Heater forced air heater lists 9.0 by 25.25 by 17.0 inches.
  • Match BTU and coverage to the room: 28,000 BTU for up to 1400 sq. ft. on the ProCom, 125,000 BTU for up to 3,125 square feet on the Mr. Heater.
  • Plan the fuel hookup: the Mr. Heater includes a 10 ft. hose and regulator, and the Remington states the tank is not included.
  • The ProCom needs no electricity, so it runs during a power outage; the other listings state nothing about power.
Heater safety

Never run a fuel-burning heater, generator or engine in a closed garage: carbon monoxide builds up fast and has no smell. Fit a CO alarm, keep clearances to cars and storage, use vented gas heaters installed to code, and put 240V electric heaters on a dedicated circuit. See CPSC carbon monoxide guidance. Read our Safety Disclaimer.
