Yes, there is a rebate thing going on. Thanks for the tip on the Rheem. I now need to find an installer.IMHO the Rheem heat pump water heater is far and away the best choice. AND... AND ~70% of the energy it uses to heat water is technically solar. ~100% if you count the energy from your PV I bet there's tons of rebates in SF for installing one.

Okay, so how is technically 70% of the energy solar??? If I have it in a utility closet?
