PURPOSE:To eliminate the need to supply electric power or the like from outside for the circulation of heat exchange medium and at the same time improve the usable utilization of collected heat energy by a method wherein the heat exchange medium is circulated while changing its phase. CONSTITUTION:A heat exchange medium outlet 29 is connected through a pipe line 12 to a condenser 13, the other end of which is connected through a pipe line 20, a valve 16 and a pipe line 18 to a closed tank 8. Radiation fins 11 are provided on the surface of the closed tank 8. A pipe line from the heat exchange medium outlet 29 is branched by a branch pipe line 6 and connected through a valve 7 to the upper port of the closed tank 8. A branch 19 is provided between the pipe lines 18 and 20, and connected through a valve 17 to a heat exchange medium inlet 26 by means of a pipe line 21. The water 33 is applied by the pressure of feed water at all times, because the water 33 is connected through a lower inlet 31 to city water. Accordingly, when a hot water tap 32 is open, cold city water is pushed in a hot water storage tank 15 and the hot water in the upper portion of the hot water storage tank 15 is delivered through the hot water tap 32. The heat exchange medium employed in the titled hot water supplier is a material, which shows two phases or vapor and liquid depending upon the temperature and pressure of a system. |
