The HWS100 Whole-House Perfect Mix Water System captures the mineral-free condensed water that is produced from a high-efficiency furnace and mixes it with tap water, as needed. A user will never be without a clean, nonacidic, renewable water supply for the humidifier. This system features simple installation and maintenance and is designed to be used on standard and high-efficiency warm air furnaces, with or without a dedicated condensate pump. An internal float valve regulates a designated amount of tap water from the saddle valve. Connect any 24-V humidistat to the water valve for precise control.
