Electric is an expensive way to heat water. Before going with tankless, I'd get a standard water heater (30 or 40 gal) and supplement with solar water heating tubes. You are eligible for the 30% federal tax credit for the solar heating equipment. Thing is if you have to replace your existing tank, now is the time to spring for the stainless tank with internal heat exchanger designed for solar heating. It would not surprise me if your electricity needs for water heating would go to zero.

Otherwise, the Home Depot 40 gallon GE sounds good, particularly if it is already cheaper than the 30 gallon model. Buy some extra insulation for the tank, and you could spring for the heat traps for a little extra efficiency. jurgen
