ABSTRACT:
An apparatus to heat potable water aboard a recreational marine watercraft includes a metal enclosure that sits atop one burner of a conventional galley stove powered separately from the engine and the source of AC power. Potable water is circulated through a tubing unit mounted within the enclosure by a pump operated by a low DC voltage. The heated potable water is then transferred back to the potable water holding tank through a check valve which prevents reversed flow of the heated water. This provides a boater with the ability to maintain a source of hot water while away from shore power or while the engine is turned off. The top of the enclosure is partially open to allow use of the burner for cooking, or boiling water as needed with the cooking vessel being placed atop of the enclosure.
