<p>A combination hot water and distilled water system including a steam generator (72) that supplies water vapour through a condensing coil (50) and back to a holding tank (52) of sufficient capacity to supply distilled drinking water for a household. The condenser (50) is mounted within and near the bottom of a hot water tank (59) so that the energy given up by the condensing water vapour is usefully deployed in heating at least some of the water in the hot water tank before the water encounters the existing or traditional energy sources. A control means is mounted in the combination hot water and distilled water system to intermittently energize the steam generator under conditions that substantially balance the supply of undistilled hot and distilled water to normal demand. In one embodiment, the evaporating heating element in the steam generator (52) is energized when the temperature drops below a predetermined level as measured by a thermostat (160) near the condensing element (50) in the hot water tank (59). Distilled water is generated upon demand for hot water and stored in the holding tank (52) in sufficient quantity for later use. Excess distilled water is overflowed to the drain.</p> |
