Non-sacrificial anode for use in a hot water heater has a single elongated electrically conductive wire extending within the interior of the water heater tank. Anode distribution points made of platinum coated tantalum are attached to the conductive wire at pre-selected locations. A catalyst of the type which permits hydrogen gas and oxygen gas at standard temperatures and pressures to form water molecules is suspended from the tank's interior. |

DETAILED DESCRIPTION In a principal aspect, the improved hot water heater of the present invention includes a non-sacrificial anode having a single elongated wire with a plurality of discreet anode distribution points.
The elongated wire is made of an electrically conductive material and is connected to an external electrical source.
The anode distribution points are electrically conductive, chemically stable, galvanically inert, substantially water insoluble and non-toxic.
The wire is projected or positioned within the interior of the heater and the anode distribution points are connected to the electrically conductive wire at pre-selected locations.
The anode points thus cooperate with the tank to direct a protective positive electrical current from the interior of the tank to the entire area of the tank's interior surface.
The non-sacrificial anode further includes a catalyst element of the type which permits hydrogen gas and oxygen gas at standard atmospheric temperatures and pressures to form water molecules.
The catalyst, which is disposed at the top of the tank, is chemically stable, inert, substantially water insoluble non-toxic and harmless in contact with food stuffs.
The hot water tank is of a substantially conventional construction comprising a hollow metal tank or shell with at least one opening and an interior surface defining an interior therein.
The tank is generally formed, at least in part, of a galvanically active material and is lined with an electrically non-conductive galvanically inert material.
The hot water heater also includes a conventional heating element, generally disposed within the interior of the tank.
Thus, it is an object of the present invention to provide a hot water heater and non-sacrificial anode which provides a protective current over the entire interior surface exposed to water.
It is a further object of the invention to provide a hot water heater and single filament platinum coated non-sacrificial anode which has a long life even when operating at voltage levels sufficient to protect the entire interior surface of the tank
