Pros
- Very efficient: a certified UEF of 4.07, about a quarter of the electricity of a standard electric tank
- Built-in Wi-Fi: set schedules and vacation mode from the EcoNet app
- 10-year tank and parts warranty plus 1 year of labor
Cons
- Switches to the backup element when the room drops below 37 °F, so it saves little in a freezing garage
