ABSTRACT:
An automatic water heater system having, contained in a tank, a plurality of vertically extending spiral flame tubes surrounded by substantially vertically extending heat tubes which join the top ends of the spiral flame tubes to form a common exhaust outlet for both sets of tubes, thereby greatly increasing the surface area contact between the water and transfer medium. The heat tubes are especially designed to provide an outlet drain for possible condensation that can develop so as not to drain out through the flame tubes and onto the flame. A heat trap, to capture heat from the hot flue gases otherwise lost by normal passage up through the chimney, may be provided, as well as a blower in the exhaust outlet. The above described structure can be assembled either as a combination heating and storage tank in a single unit, or as a separate component heating unit connected to the storage tank located alongside it.
