PURPOSE:To reduce a heat discharge loss and to simplify the piping structure by a method wherein a float type flow rate switch is provided at the junction of a forward pipe and a hot water feed pipe of a heat collector so that a solar heat collecting operation and a hot water feeding operation are performed by the flow rate switch. CONSTITUTION:A float type flow rate switch 12 is provided at the junction of the forward pipe 3 and the hot water feed pipe 10 of the heat collector, the switch 12 has an inlet section 14 and an outlet section 15 connected to the pipe 3 on both sides thereof and an inlet port 16 connected to the hot water feed pipe 10. Further, a float valve 17 is provided within the switch 12 so as to open and close the outlet section 15 to the forward pipe by the opening and closing operations of a hot water feeding faucet 11. In addition, switching mechanisms 20 and 24 adopted to perform the ON and OFF operations of a pump 8 by the up and down movements of the float valve 17 are provided. As a consequence, the efficiency of the hot water feeder is improved. |
