Heat Pump Hot Water Heater – reliability and longevity – GreenBuildingAdvisor

Curious if any heat pump hot water heater owners can comment on the reliability and longevity of their units?

I’m building an all electric house, and my mechanical contractor is recommending I swap my heat pump hot water heater for a more traditional electric hot water tank instead. He claims they’ve run into a lot of issues with installed HPHWH (which homeowners installed due to generous government incentives) and have had to take these out and replace them with either gas or electric resistance heaters instead. He says while HPHWH would have lower operating costs, these are mostly offset by higher ongoing maintenance and repair costs as compared to a traditional electric resistance hot water heater.

Any real-life commentary on how well these HPHWH are working in the field? (I’m aware of all of the compaints about noise from the Rheem units in particular, but am curious about broader longevity and reliability concerns).
