PURPOSE:To make the most use of hot water in the titled hot water feeder by a method wherein the hot water feeder utilizing solar heat and another hot water heater are connected to an object requiring the hot water through a three-way valve and when the temperature of the hot water in the hot water feeder reaches a predetermined value, the three-way valve is switched by a control section in response to audio signals. CONSTITUTION:The solar heat hot water feeder A is formed of a heat collector 1, a circulation pump 2 and a solar heat accumulation tank 3 and the course of the hot water switched to the hot water heater 4 from the hot water feeder A is formed by the electrically operated three-way valve 7 so that the hot water from the water heater 4 is guided to a hot water feeding port 5 by the valve 7. Further, the operation of the valve 7 is performed by the control section 8 after the detection of the temperature of the hot water in the solar heat accumulation tank 3 by a thermosensor 6. In the control section 8, a desired hot water temperature is set in advance by a temperature adjuster 12, the temperature detected by the thermosensor 6 is displayed by a display device 14 and compared to the set temperature by a comparator 13 and two kinds of voices are anounced through a speaker 16 in proportion to the loudness of the voices. Consequently, the user may switch properly the three-way valve 7 by a switch 17 in response to the two kinds of voices. |
