PURPOSE:To improve solar heat utilization ratio by providing a sensor for detecting the heat medium of the heat regenerating tank and a sensor for detecting the temperature of the heat medium entering into the heat regenerating tank, and a differential temperature thermostat for controlling the operation of the heat medium pump in accordance with the difference between the temperatures detected by both sensors. CONSTITUTION:In the titled solar heat utilizing device, the difference in the temperatures detected by the sensor 2 for detecting the temperature of the heat medium of the heat collector 1 and the sensor 3 for detecting the temperature of the heat medium returning to the heat collector 1, is detected by a differential temperature thermostat 16. In a case where the temperature detected by the sensor 2 is higher than that of the sensor 3, the heat medium pump 5 is operated. When the solar radiation is terminated and the temperature detected by the sensor 2 becomes lower than that of the sensor 3, the above pump 5 is stopped. Upon this occasion, when the temperature detected by a sensor C for detecting the temperature of the heat medium in the heat regenerating tank 6 provided with the hot water supply function becomes smaller than the temperature detected by a sensor D for detecting the temperature of the heat medium in the passage from a three-way valve 12 to the heat regenerating tank 6 the operation of the heat medium pump is resumed through a differential temperature thermostat 15. |
