I have had a GE heat pump water for a few years now, I use it in the mixed mode. So most of the time it operates in heat pump mode, but when there is a high water demand it switches to regular resistive heat mode. The unit beeps to remind you to clean the air filter.
Why do you need two of them?
Remember that you'll need a drain line, as it also acts as a dehumidifier and an AC unit.
The house has two water heaters now due to the design and layout. Both need to be replaced.--
So put me on a highway, and show me a sign.
And take it to the limit one more time...
