Combination diesel/electric heating appliance systems
First Claim
1. A heat exchanger for a boat or vehicle utilizing an engine circuit, a potable water circuit and a auxiliary heater circuit, each of said circuits carrying a separate fluid and being isolated from said remaining circuits so as to prevent mixing with any of said remaining circuits, either or both of said engine circuit and said auxiliary heater circuit providing heat to said potable water circuit, and a fluid flow volume sensor in said potable water circuit, said fluid flow volume sensor being operably connected to a controller, said controller initiating operation of said auxiliary heater circuit following a predetermined volume flow of said potable water being reached and measured by said fluid flow volume sensor.

Abstract
A diesel/electric appliance for heating coolant within an auxiliary heater circuit and for heating potable water within a potable water circuit. The appliance includes a diesel powered auxiliary heater and a coolant jacket surrounding the burner of the auxiliary heater. Electrical resistance elements are immersed within the coolant jacket to maintain the temperature of the potable water circuit by transferring heat through a heat exchanger to the potable water circuit.
