My utility company chipped in $1,600, so it ended up being the cheapest option anyway. The federal tax credit is 30% of the project cost up to $2,000, and it is still good if you install before the end of the year.

This 65gal Rheem heat pump water heater goes for $2,150 plus shipping and install.

This 55gal Rheem resistance water heater goes for $820 plus about equivalent shipping and install as a heat pump water heater

The utility company for me. They chipped in $1,600!
