A supplemental heating system for heating a first fluid such as potable water. The supplemental heating system is configured for use in a recreational vehicle having a primary heating system that also heats the first fluid. The supplemental heating system includes a heating element that heats a second fluid and a heat exchanging component removably fitted into the recreational vehicle and having a first fluid conduit for permitting the first fluid to enter and exit the heat exchanging component, and a second fluid conduit for permitting the second fluid to enter and exit the heat exchanging component. Heat from the second fluid is transferred to the first fluid within the heat exchanging component and thereby provides a heating operation of the first fluid independent of the heating system of the recreational vehicle.
