Speaking of heat pumps and water heat, I installed both a heat pump and hybrid water heater to save on electricity. The water heater doesn't seem to have made much of a difference in my electrical bill, my guess is the problem is peak demand so I should have gotten a much bigger tank than before. Ambient garage temperature may also be an issue but it exhausts outside and the garage is insulated so it generally stays above 55 degrees.

Make sure you are in energy saving mode. The default for these systems is to try and do quick recovery which likely isn't what you want.

Ah. I installed one in a uninsulated garage and it was really a big savings. It’s basically a free ac for whatever space it’s installed in

While those save money, most people don't really use a lot of hot water and so the amount they can save is limited.
