Pros
- Thermostat control on a heater this price, so the room holds a set warmth without fiddling with the valve
- Runs with no power, so it keeps heating through an outage
- Base feet and wall bracket both included, so it can stand on the floor or hang on a wall
- At 14 lb it is light and compact enough to hang in a small office or den
Cons
- Natural gas only; it cannot be converted to propane
- The manual forbids installing it in a bathroom, and many codes bar vent-free heaters from bedrooms too
- Only a one year parts warranty
