You > might be able to find a 2000W/120V/~8ohm element. Not many of us have 250 watts of solar available. Even if you add wind, you can't be guaranteed of having 250 watts available. Does anyone know the duty cycle of the hot water heater? I suspect it is fairly low if you don't use much hot water.
