ABSTRACT:
The water heating apparatus is formed by a container having spaced upper and lower walls and a cylindrical side wall having upper and lower portions extending between the upper and lower walls defining an interior of the container. An inlet opening is formed through the central portion of the upper wall. An elongated hollow flame tube is located within the interior of the container and has an upper end coupled to the inlet opening of the upper wall and extends downward. A combustion device is coupled to the inlet opening of the upper wall for directing a flame into the flame tube by way of the upper opening. A plurality of water nozzles coupled together at spaced apart positions by conduits are located in the upper portion of the interior of said container below the upper wall and at spaced apart positions around the upper portion of the flame tube for directing water against the flame tube for cooling purposes and downward into the zone between the flame tube and the side wall for forming hot water for flow into the lower portion of the interior of the container. An exhaust opening for an exhaust device is formed through the upper wall. The upper wall is removably coupled to the upper end of the side wall. The upper and lower portions of the side wall are removably coupled together.
