- Runs about three days on a full 170 lb hopper at the low setting
- Holds a room temperature in thermostat mode instead of needing constant adjustment
- Start it and adjust it from a phone over Wi-Fi or Bluetooth
- Limited lifetime warranty on the firebox and heat exchanger
- Stops heating in a power cut unless you have backup power
- EPA tested peak of about 32,600 BTU/h, so the 3,000 sq ft claim is optimistic for a cold climate
- Only wired wall thermostats work; smart thermostats are not supported
