Abstract The present invention relates to a water heater enamel internal container protection method and its equipment. It is comprised of water heater main body, titanium metal bar-titanium anode bar and correspondent low-voltage D.C. power supply. Said D.C. power supply consists of rectification, filtering and voltage-stabilizing circuit, state display circuit and back-up battery which can be charged when it is under work. After the water heater is stopped for several days, it still can make titanium bar be in positive potential so that the enamel internal container can be protected by means of titanium anode bar applying positive valtage to eliminate weak electrolysis harmful effect so as to greatly elongate service life of water heater.
