We never run out of hot water. Not even with three showers at the same time. We are in California so we try to keep our shower time down a bit. I have the temp set at 111 degrees so we can just turn on the hot water valve and the temp is perfect. If I was to turn up the temp to 120 then we would definitely never run out of hot water but we'd have the inconvenience of using the hot and cold shower valves to get our preferred temp.Is 45 gallons big enough for 3 people? How often does it go into resistance mode?
I am not sure how often, if ever, that it goes into resistance mode. It can be set for heat pump only, resistance only, or hybrid resistance/heat pump. The manual states, and the phone app states as well, that the hybrid mode is the most efficient. So, that it where I have set it.
