Abstract

PURPOSE: To increase the heat collecting efficiency by detecting the temperature difference between a water storage tank and a heat collector by temperature detectors such as thermistors mounted on respective parts, and controlling the rotational number of a heat medium circulating pump, for exmaple, by the temperature difference thus obtained to vary the flow quantity.
CONSTITUTION: When a heat medium within a heat collector 1 is heated, the temperature is detected by a thermistor 9 and the resistance value is gradually reduced. When the potential of the plus side of a comparator 16 becomes higher than the minus side thereof the comparator 16 is turned ON, and a contact 14 is closed by the excitation of a relay 12. Then, a circulating pump starts its operation to circulates the heat medium in the direction shown by the arrow, and the temperature of water within the storage tank 7 is raised through a heat exchanger 8. Then, when, the temperature of the heat collector 1 further rises up and a comparator 15 is turned ON, a contact 13 is reversed from Hi to Lo by the excitation of the relay 11, and the flow quantity of the pump 4 becomes high. Thereafter, the temperature of stored water becomes high, and the potential between the thermistors 9 and 10 becomes low, and the pump 4 is rendered low, and is finally stopped.
