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? http://www.surpluscenter.com/Electr...

Cheapest way is to have a valve to divert water from the lines back to the cold water tank. No additional (high temperature) pump needed.
