Abstract: An ice making apparatus is disclosed. The ice making apparatus includes a compartment enclosing an ice cube freezing form and a refrigeration system. A fresh water reservoir within the compartment is utilized to provide water for the ice cube freezing form and a drain within the compartment removes excess fluid which results from overflow and ice melting during ice removal. An ice cube storage bin is also provided with a drain for removal of fluid from melting ice. Waste fluid from both drains is coupled to one end of one of a pair of helical concentric conduits and a source of fresh water is coupled through the other concentric conduit to the fresh water reservoir, in order that the fresh water may be substantially precooled prior to ice making. In a preferred embodiment of the present invention, an overflow reservoir is provided so that excess fluid from each drain is coupled to a waste drain.
