Abstract
An apparatus, made in accordance with the present invention, comprises an ice-making unit for making pure ice using a refrigeration system, an electric heater for melting into fresh water the ice produced by the ice-making unit, a tank for storing the fresh water resulting from the melting, a sensor for sensing the water temperature prevailing in the tank, and a control responsive to a signal from the sensor to actuate the heater for maintaining the water temperature at a predetermined value. The apparatus further comprises a sensor for sensing the water level in the tank, and a control responsive to a signal from the water level sensor to control the operation of the ice-making unit for maintaining the water level at a predetermined value.
