800w / 12v DC Water Pre-Heater???

Over at "Surplus Center" they have a 800w / 12V water heater for $20

Would this have value as a preheater at the sink or shower level to get hot water faster?

    800 watts will heat water substantially. It will also draw 70 amps or so. How many batteries are you carrying?
