Abstract
An apparatus for supplying both hot water and distilled water includes a water distillation unit having a steam generator, a condenser connected with the steam generator for converting steam into distilled water and a holding tank for receiving distilled water from the condenser. The condenser is in heat transfer relation to the interior of a water heater tank. Water level monitors are provided for monitoring the level of water in the steam generator and the holding tank and temperature sensors sense the temperature of water in the steam generator and water heater tank. When the level of water in the holding tank is above a predetermined value, the steam generator is de-energized and feed water is admitted to the steam generator to dilute the contents to a safe temperature before the contents are discharged to drain. The steam generator may be energized in response to the temperature sensor in the water heater tank indicating a demand for hot water or the holding tank level monitor indicating a demand for distilled water. If the demand for distilled water increases the temperature in the water heater tank above a predetermined value, excess hot water is discharged to drain. If the demand for hot water causes the production of distilled water to exceed the capacity of the holding tank, the excess is discharged. The steam generator may alternately be controlled only on the basis of the level of distilled water in the holding tank. First and second auxiliary heaters are provided and are energized, respectively, when the temperature of water in the water heater tank is below a first predetermined temperature value provided that the steam generator is not energized and when the temperature of water in the water heater tank is below a second predetermined temperature regardless of the status of the holding tank.
