How to choose
Read coverage as the maker's figure
All three picks run on natural gas, so fuel type will not separate them. The useful number is the coverage each maker gives: 1,000 sq ft for the Mr. Heater and the Dyna-Glo, and 500 sq ft for the ProCom. These are the makers' own ratings, so compare them against your room's floor area before choosing.
Thermostat versus fixed heat settings
A thermostat lets the heater hold a set temperature, while plain heat settings only pick a power level. The Mr. Heater has a built-in adjustable thermostat, and the ProCom offers High, Medium and Low thermostat control. The Dyna-Glo uses a LOW-MED-HI variable control knob for its heat settings, so pick the control style that fits how you heat a room.
Venting, power and placement
All three picks need no electricity and no outdoor venting, so an outlet or a vent route does not decide the choice. The Mr. Heater mounts on a wall with hardware in the box, the ProCom mounts on a wall or stands on base feet, and the Dyna-Glo mounts on a wall with optional base legs sold separately. Check the mounting option that fits your room before buying.
