An electric water heater comprises two nested electrodes 4,5, a pressurized air source 11 with means 13 to synchronize the control the inflow of source water and pressurized air and valve means controlling the flow of heated water to a blending chamber prior to exit to an external hot water reservoir 14. Easily adaptable for use in various locales having varying water qualities, the heater is also able to maintain a proper water temperature and can immediately discharge the water between the electrodes when required. In a preferred embodiment, the electrodes on the heater are substantially inverted frusto-conical in shape. Means 8 are also provided for adjusting the distance between the electrodes when desired. <IMAGE> |
