Abstract

An improved combination anode mount and hot water outlet for a water heater. The water heater includes a tank to contain water to be heated and the tank has an upper head with an opening therein. An annular internally threaded spud is welded to the upper surface of the head in alignment with the opening in the head. The anode mount and hot water outlet includes a tubular metal body having an upper threaded end which is threaded to the spud. A wall or closure extends transversely across the body intermediate the ends and divides the body into an upper chamber and a lower chamber. Ports are provided in the body and establish communication between the tank and the upper chamber and serve to conduct heated water from the tank. The upper end of an anode formed of a metal electro-negative to steel is mounted in the lower chamber of the body and the steel core wire of the anode is welded within a hole in the transverse wall. The tubular body can be coated with a corrosion resistant metal and the portions of the body exposed to water in the tank and also be provided with an outer plastic coating.
