ABSTRACT:
A heating appliance operable with a single heat source to heat both circulating water and water for domestic use includes an upright cylindrical reservoir containing water for household use and having an inlet at its lower end and an outlet at its upper end. A closed cylindrical tank of smaller diameter extends vertically concentrically through the reservoir and contains an electric immersion heating element for heating circulating water flowing through the tank from a lower inlet to an upper outlet. An elongated cylindrical tube in the reservoir extends concentrically about the tank in closely spaced relationship thereto and has a closed bottom end secured about a lower portion of the tank and an open upper end spaced from the upper end of the reservoir. The tube has circumferential openings disposed adjacent its bottom end for admitting cooler water from the reservoir into the space between the tube and tank for rapid heating of the water for household use by the flowing heated water circulating through the tank.
