ABSTRACT:
A water heating apparatus using electrodes is provided. The water heating apparatus includes a heating tank in which electrolyte solution is stored and a plurality pairs of heating electrodes composed of positive electrodes and negative electrodes arranged in the heating tank at uniform intervals. Since the plurality of pairs of electrodes are arranged in the heating tank at uniform intervals, the heating operation can be always performed in a state where the electrolyte solution of no less than the minimum water level is stored regardless of the direction of the heating tank so that it is possible to heat water or to generate steam. Therefore, the water heating apparatus can be easily applied to a product that is inclined or upset and that is not in a specific direction.
