Electrical upgrades are almost always required, and price is more like 7k-9k around here. It's going to be seriously painful for a lot of people.

If you were in the market for an resistive electric heat pump, you likely had the service for it already. A heat pump version will almost always require less power.

If you currently have an electric resistive water heater, a heat pump water heater with the same heating capacity will use 3-4x less power, which means you can use a much smaller circuit.

A 6kW 240V EWH uses 25A, it’ll need #8 wire and a 35A or 40A breaker.

An equivalent HPHW would use 1.5kW at 240V, or 6.25A. You can use #14s and a 15A breaker.

My bad, read too quickly. I was thinking of the forced change over from gas water heaters, which is already happening in the California Bay Area and will only expand.

Ehh 120v models exist. My 65 gal runs fine on a standard 20a breaker.
