One downside of the heat pump water heater is no hot water during a power failure. Same holds for gas water heaters with blowers or exhaust fans.


This would be the case with any electric water heater as well, right?

That is correct.

Also, my gas water is 25 years old, still works and looks like new. I did replace the sacrificial anode once, something that very few people do.


Isn't that a metal rod that's in there to specifically corrode rather than the tank lining?

That is also correct. Mine was 15 years old when I changed it, had maybe another year or two left.

One other thing to note - the heat pump water heater in your original post is listed as having 3X the efficiency of a standard electric heater. Depending on your utility rates I'd be surprised if it comes close to a gas water heater in terms of $ per gallon of hot water.
