*-Because a heat pump system is using energy to "move" existing heat, it gives you 400% (or more!) efficiencies. [i.e. you use 800 watts to drive a compressor and fans, but get 3,200 watts of heat into the tank, while cooling the area around the water heater.]
I haven't shopped for heat pump water heaters. It looks like I should. Does the "800 watts" mean that they will operate on 120vac? I have recently resolved to stop using my propane water heater but do not have 240vac wiring to the water heater closet area.
