PURPOSE:To eliminate an installation of a heat accumulation bath with a high capacity by a method wherein there are provided a solar energy heat collector and an auxiliary heat source having a heat collective area set so as to have a substantial coincidence of a heat collective capacity and a load during a period having an annual high insulation, and the auxiliary heat source is controlled under a sensing of the temperature of outlet hot water. CONSTITUTION:Area of the solar energy heat collector 1 is set so as to cause a heat collection value and a load to be substantially coincided with during a period having a high insulation, the collected calory is fed to the tank 5 constituting a calory adjustor 4 through a pipe 3 by the water flowed to the water feeding pipe 2. Hot water fed to the tank 5 is transmitted to a load working equipment through a pipe 7, for example, a hot water feeder 8. At this time, the hot water in the calory adjustor 4 is adjusted for its temperature by an auxiliary heat source such as steam etc, fed through a solenoid valve 10 from a pipe 9 of the auxiliary heat source device 12 such as a boiler. The solenoid valve 10 is controlled in response to the output of a thermocouple 11 for sensing a temperature of hot water flowed in the pipe 7. |
