<p>PURPOSE: To avoid the riskiness at the time of bathing when hot water is at a high temperature unsuitable for the bathing by closing switching means by a control means when the detected temperature of a supply water temperature detecting means for detecting the water temperature of hot water from a solar heat collector is a target supply water temperature or higher. CONSTITUTION: When a detected temperature Ti of hot water by a thermistor 8 for a bath is higher than a set target temperature Ts, a switching valve 15 is closed to stop supplying of the hot water, and it is informed by lighting a lamp 26 and ringing of a buzzer 27. Thereafter, if a hot water supply continuous switch 28 is not closed within a predetermined time, the lighting of the lamp 26 and the ringing of the buzzer 27 are stopped. When the switch 28 is closed, a solenoid valve 12 and the valve 15 are opened, the hot water from a solar heat collector S is mixed with water from a water supply unit 10, and so controlled as to become the target temperature Ts by regulating the opening of a mixing valve 13. Accordingly, the riskiness such as a scald at the time of bathing is effectively avoided.</p> |
