Design of Solar Preheating System for Boiled Water

Based on the current situation of energy and disadvantage of present solar heating water methods, a high-efficiency and secure hot water service system indirectly utilizing solar power has been introduced. The hot water preheating process is added to this system. It can make full use of solar-energy, shorten the time for heating, reduce energy consumption, cut the cost without polluting the drinking water. This system is applicable to population concentrating and large boiled water demanding areas.
