Abstract
A container construction and combination in which a container for confining water or other fluid to be heated is provided with a metal heat exchanger disposed within the container. The heat exchanger is comprised of a single wall tube structure having outwardly directed fins extending in a vertical direction within the container. Means are provided for connecting an upper end of the heat exchanger to a source of heated refrigerant through an upper opening provided in a side wall of the container, the refrigerant being vaporized when heated, and condensed when cooled in the heat exchanger. The disposition of the heat exchanger permits the force of gravity to remove condensed refrigerant from the heat exchanger. Means are provided for returning condensed refrigerant to the source of heated refrigerant from a lower end of the heat exchanger and through a lower opening in the side wall of the container. And means are provided to free the combination of galvanic action when a fluid to be heated is present in the container.
