Abstract:
In combination:a. domestic hot water heating tank including:a liquid receptacle having a top surface with an inlet and an outlet;a cold water inlet pipe secured to the inlet;a hot water outlet pipe secured to the outlet; andmeans for heating liquid within the liquid receptacle;b. a water distillation apparatus, comprising:an elongate degasification chamber having a top and a bottom, a liquid inlet adjacent to the bottom, a gas outlet adjacent to the top, a liquid outlet intermediate the top and the bottom, and means for controlling a level of liquid within the chamber;a liquid conduit extending between the liquid inlet of the degasification chamber and the hot water outlet pipe of the domestic hot water heating tank whereby preheated water is conveyed from the hot water outlet pipe of the domestic hot water heating tank to the liquid inlet of the degasification chamber;an elongate boiling chamber having a top and a bottom, a transfer conduit connecting a liquid inlet intermediate the top and the bottom with the liquid outlet of the degasification chamber, a steam outlet adjacent the top, a heating element being disposed within the boiling chamber whereby liquids within the boiling chamber are heated to a boiling point with resulting steam passing out through the steam outlet, the boiling chamber having a removable scale retention mesh and an opening through which the scale retention mesh is removed, a level of water within the boiling chamber being governed solely by equalization with a level of water within the degasification chamber, heat passing from the boiling chamber through the transfer conduit back to the degasification chamber, thereby increasing a temperature of fluids in the degasification chamber; andan annular condensation chamber having a steam inlet and a liquid outlet, the steam inlet being connected to the steam outlet of the boiling chamber, the annular condensation chamber sitting on the top surface of the liquid receptacle of the domestic hot water heating tank encircling the cold water inlet pipe such that a heat exchange takes place between the cold water inlet pipe and the condensation chamber.
