When they changed the rules in Hawaii so no more resistance tank heaters could be used in new homes most of the new construction seemed to be solar hot water. Now all I see is heat pump. I'm guessing it's the up-front cost to the builder.
The heat pump variety has to vent the cold air somewhere. Depending on how you configure one you could probably push that into your living space, so you could get some collateral climate control with your hot water.
