<p>PROBLEM TO BE SOLVED: To provide a hot-water supplier utilizing solar heat, which indicates heat-collecting state of a hot-water storage tank, based on the condition of operation of a pump and indicates the collecting amount of heat which is acquired by water in the hot-water storage tank from heating medium. SOLUTION: The hot-water supplier utilizing solar heat is provided with a temperature sensor 8 for measuring a high-temperature heat medium temperature, heated in a solar heat collector 1 and another temperature sensor 5, for measuring a low temperature heat medium temperature, after effecting heat exchange in the hot-water storage tank 2, while a pump 3 is operated by a control device 9, when the high-temperature heat medium temperature is higher than a low-temperature heat medium temperature, and the condition of collecting heat is indicated in an operation indicating remote controller 10. The collecting amount of heat acquired by the water in the hot-water storage tank 2 is calculated by the control device 9 through data measured by a flow rate sensor 7 for measuring the flow rate of heat medium supplied from the solar heat collector 1 into the hot-water storage tank 2 and the temperature sensors 5, 6, and then the operated data are indicated through a heat-collecting amount indicating bar 18.</p> |
