@Clifford Thanks!
I run energy saver most of the time but set it to high demand in the evenings but I have yet to see a spike if/when the element kicks on. I don't even think we are using enough water to make the element kick in so I bet we could stick with energy saver all the time.

Hybrid in this case is it is using a heat pump to pull heat from ambient air and transferring the thermal energy to the water as well as using a heating element if needed.
It has a few modes of operation:
Heat Pump Only - only heat pump, low regen
Energy Saver - heat pump and element, high regen
High Demand heat pump and more element, faster regen
Electric only - fastest regen, lots of power
Vacation - maintain ~60 degree water
