Abstract
A bi-metallic anode is disclosed for use in small hot water heaters such as in recreational vehicles, motor homes and the like. The anode includes a threaded portion and a shaft formed from a relatively non-corrosible metal such as steel, A second section made from a corrosible metal such as magnesium is affixed to the shaft. In use, the shaft spaces the corrosible section from the inner tank wall and fitting, thus providing for a more effective and longer lasting hot water heater.
