Our Verdict
This heater puts out 17,000 BTU and covers up to 570 sq ft. It mounts to your wall and vents through an exterior wall. You do not need a chimney or electricity to run it.
The safety pilot cuts gas flow if the flame goes out. A built-in pressure regulator adds another layer of protection. The adjustable thermostat keeps your room at the temperature you set.
This unit stays fixed on one wall. You cannot carry it from room to room. It works best in a space you heat on a regular basis.
There is no timer or remote control on this heater. You must walk to the unit to change settings. Many competitors at this BTU level include wireless controls as a standard feature.
This heater fits homes with natural gas access that need reliable, powerful heat. It works even when the power goes out. That makes it a dependable option for cold-climate households.
