<p>PROBLEM TO BE SOLVED: To provide a hot-water feeding apparatus utilizing solar heat, in which delays in operation until the discharging of hot water adjusted to a desired hot-water feeding temperature is reduced, and which is highly handleable. SOLUTION: There is provided a method for controlling the temperature of hot water fed out of a hot-water feeding apparatus, utilizing solar heat in which (a) an auxiliary heat source machine 17 is operated under the conditions: if a hot-water temperature (TT) at the upper segment of a hot-water storing tank is higher than the desired hot-water feeding temperature (set temperature: TR), and (b) an auxiliary heat source machine 17 is operated (auxiliary heating) if the hot-water temperature (TT) at the upper segment of the hot-water storing tank is lower than the desired hot-water feeding temperature (set temperature: TR). [Condition]: When a hot water temperature (TS) at the outlet port of the solar heat type hot-water feeding machine is lower than the desired hot-water feeding temperature (set temperature: TR), the auxiliary heat source machine 17 is operated (auxiliary heating), and in turn, when a hot water temperature (TS) at an outlet port of the solar heat type hot-water feeding machine exceeds the desired hot water feeding temperature (set temperature: TR), the auxiliary heat source machine 17 is stopped.</p> |
