ABSTRACT:
The efficiency of the system disclosed in my U.S. Pat. No. 4,897,099, wherein purified ice pieces and purified liquid water are derived from tap water, is improved by transferring heat from the tap water to the collected ice pieces. The transferred heat warms the ice pieces to decrease the energy required to melt the ice pieces and form the purified liquid water. The heat transfer also pre-chills the tap water to assist in forming the ice pieces.
