Sounds great, but, I looked at one that draws 20 amps; only 33* heat rise in the water. That tells me in winter, if city water is 65*, I don't have but 98* hot water. Too cool for me.
I don't think I would want to go over 20 amps. Seems the water heater draws about 12 amps now. They do make propane ones, but IIRC, they are very expensive.
