ABSTRACT:
A water distiller assembly comprising a bottom boiler unit and a top condensing unit incorporates heat exchange passage means for supply water and steam arranged in the condensing unit in such a way in combination with tubular flow connections between the condensing unit and boiler unit that cool, incoming supply water is preheated by steam rising from the boiler unit and flows by gravity down into the boiler unit, with the steam thereby being cooled and condensed to distilled water. Mineral laden residue water in the boiler unit is discharged therefrom continuously by means of a discharge passage providing a predetermined flow restriction against the flow pressure generated by the vapor pressure in the boiler unit. A supply water vessel forming a portion of the condensing unit is removably secured to the top of a boiler vessel by spring clips, which also serve to tightly seat lids covering the supply water vessel and the boiler vessel.
