Our Verdict
This heater puts out 28,000 BTU of heat. It warms up to 1,400 sq ft. That covers a large living room or open floor plan.
It runs on liquid propane with no electricity needed. This makes it useful when the power goes out. You do not need an outlet to run it.
The ODS sensor watches oxygen levels in your room. It shuts the heater off if levels drop too low. This is a key safety feature for ventless gas heaters.
You get a thermostat with High, Medium, and Low settings. But there is no remote control or timer. You must walk to the unit to make changes.
The heater mounts on a wall or stands on the floor with base feet. Both the wall hardware and base feet come in the box. You choose which setup fits your space.
