<P>PROBLEM TO BE SOLVED: To provide a daily life water supply system which makes an environment load small, and which can prevent a decrease in heat exchange efficiency of a hot water storage-type water heater and a decrease in water flow in piping. <P>SOLUTION: This daily life water supply system 10 comprises the hot water storage-type water heater 30, an reverse osmosis membrane device 20 which separates raw water into permeable water and concentrated water, and a means for supplying the permeable water to the hot water storage-type water heater. In addition, preferably, the daily life water supply system 10 is provided with an electrolytic cell 40 which produces acid electrolyzed water and alkaline electrolyzed water by electrolyzing water to be treated, a means for supplying the concentrated water to the electrolytic cell 40, a means for supplying a use point with the acid electrolyzed water produced in the electrolytic cell 40, and/or a means for supplying a use point with the alkaline electrolyzed water produced in the electrolytic cell 40. <P>COPYRIGHT: (C)2010,JPO&INPIT |
