Abstract
An automatic water heating and distilling apparatus is provided having a hot water reservoir, an evaporator tank, a condenser, a distilled water reservoir and a control mechanism. Water is boiled within the evaporator tank generating steam which is condensed in the condenser to form distilled water. The heat rejected during condensation is transferred into the hot water reservoir. The distilled water reservoir has an input coupled to the condenser, an output for distilled water, and an overflow so that excess distilled water is returned to the evaporator tank. The control mechanism automatically regulates the operation of a heater within the evaporator to maintain the water in the hot water reservoir within a selected operating range. Various alternative embodiments are also described including a hot water heating apparatus utilizing an enclosed heat transfer device partially filled with liquid having a boiling point above the selected temperature for the water to be heated. A heat transfer device is provided with a reservoir portion for accumulating liquid and a relatively higher condensive portion in cooperation with the hot water reservoir. A heater, a temperature sensor, and a …
