PURPOSE:To make it possible to adjust the temperature of hot water in a simple manner by a method wherein the inlet port of the titled heat collector is connected directly to a ciry water pipe so as to supply city water to the heat collector by making use of the pressure of the water without using a heat collecting pump and a flow rate control valve attached to the water pipe is controled by a temperature sensing element for detecting the temperature at the outlet port of the heat collector. CONSTITUTION:The inlet port of the solar heat collector 1 is directly connected to the city water pipe 2 through a pipe 3 and the outlet port thereof is connected to a hot water storage tank 4 through a pipe 5. The hot water in the hot water tank 4 is supplied from a hot water inlet port 6 to a hot water faucet 8. Further, a stop cock 9, a water pressure reducing valve 10, an electromagnetic valve 11 and the flow rate control valve 2 are attached to a pipe 3 is that order from on the side of the city water pipe 2. The electromagnetic valve 11 is opened and closed by a liquid level detecting switch 15 provided in a bathtub 14 and the flow rate control valve 12 is controled by the temperature sensing element 16 for detecting the temperature at the outlet port of the solar heat collector. In addition, the valve 12 is controlled by comparing the temperature of the hot water determined by adjusting a hot water temperature setting volume 19 of a control panel 17 with the temperature detected by the temperature sensing element 16 to thereby adjust the flow rate of the water to be supplied to the heat collector 1. |
