The recovery time depends on which mode you run the water heater in. I'll give a quick rundown -
1 - "eHeat" - Heat pump mode only - most efficient, slower recovery time than standard electric
2 - "Hybrid" - Primarily heats with the heat pump, but will turn on the standard electric elements during periods of high demand
3 - "Standard Electric" - Uses the heating elements only, same efficiency as a standard electric water heater
4 - "High Demand" - Runs the heat pump and the elements at the same time. Least efficient, but you shouldn't run out of hot water!
I live by myself, so using eHeat mode works fine, and I don't have to worry about running out of water. My brother and his wife installed one of these water heaters, and they tried eHeat mode and ran out of hot water a couple times. They run it in Hybrid mode now and haven't run out of hot water since making that change.
Another interesting feature is that it has a built in vacation timer, you can set how long you will be gone, and it will turn back on the day before you return.
