How to choose
Match BTU and rated coverage first
BTU names the heat output, and the maker-rated coverage tells you the area it serves. The ProCom heater gives 30,000 BTU and is rated for up to 1,400 sq ft by the maker, while the Mr. Heater heater gives 30,000 BTU and is rated for up to 1,000 sq ft by the maker. Compare the BTU figure with the maker-rated coverage before choosing, since a higher BTU figure does not always mean a larger rated area.
Thermostat options on these heaters
A thermostat holds a set temperature by adjusting heat output. The Mr. Heater heater has a built-in adjustable thermostat, and the Rinnai heater has a programmable thermostat that sets specific temperatures and works with Wi-Fi-enabled systems. Pick a thermostat if you want set temperatures rather than plain setting changes.
Check venting and placement before buying
Venting decides where a heater can go. The ProCom heater is ventless with base feet and a wall mounting bracket, the Mr. Heater heater needs no outdoor venting, and the Rinnai heater is a direct vent wall furnace. Check the venting type against your room, and confirm whether a blower comes in the box: both the ProCom and Mr. Heater blowers sell separately.
