<P>PROBLEM TO BE SOLVED: To provide a technology capable of keeping a water temperature at a lower section of a hot water storage tank at a low temperature, even when the temperature of a heat medium for heating distributed to a tank unit from a heating terminal is not low. <P>SOLUTION: This heating device includes the tank unit receiving the low-temperature heat medium for heating and distributing the high-temperature heat medium for heating by utilizing heat storage of the hot water storage tank, and a heating unit for circulating the heat medium for heating between the heating terminal and the tank unit. In this heating device, the heating unit includes a heat pump for separating the heat medium for heating directing to the tank unit from the heating terminal, into the low-temperature heat medium for heating and the high-temperature heat medium for heating. Further in this heating device, the heating unit distributes the low-temperature heat medium for heating from the heat pump to the tank unit. Furthermore, in this heating device, the heating unit distributes the high-temperature heat medium for heating from the tank unit and the high-temperature heat medium for heating from the heat pump to the heating terminal. <P>COPYRIGHT: (C)2010,JPO&INPIT |
