<p>PURPOSE:To miniaturize a heat source unit to set a hot water storage unit at an arbitrary position by dividing a boiler unit into a heat source for heating water and a hot water storage unit for storing heated water. CONSTITUTION:At first, a second and a third closing valves V2, V3 are opened, a feed pump P is operated, and water from a water feeding source is conveyed to a heat source unit 10 to be filled with water. As a result, when a heater 11 is supplied with electricity, since water in the heat source unit 10 is boiled until the water temperature of a temperature sensor 12 becomes specified set temperature, if water is supplied to the heat source unit 10 by the feed pump P again, hot water in the heat source unit 10 can be conveyed to the hot water storage unit 20. Since the heat source unit 10 is used in a condition to be filled with water and heated hot water is immediately conveyed to the hot water storage unit 20 to store, the inner volume of the heat source unit 10 may be small and need not be made a pressure proof tank. Further, the hot water storage unit 20 is an open type and its shape and set position are not restricted.</p> |
