問題点があった。However, since the above-mentioned conventional example 1 controls the amount of water with the maximum capacity from the start of hot water supply (control so as to fall within the range of the limit curve b'in FIG. 4), the hot water supply is performed. Since the rising of the temperature is slow and the control flow rate cannot be absorbed due to the difference in the heat efficiency of the gas due to the difference in appliances or the change over time, there is a problem that a stable hot water temperature cannot be obtained from the beginning of hot water supply. Is to start with a small flow rate, but when the deviation between the hot water supply temperature and the set temperature reaches within a predetermined value at the first predetermined water amount, the second predetermined water amount which is larger than the first predetermined water supply amount is set. However, there is a case where it does not reach the predetermined value due to equipment difference, and if the flow rate is set to eliminate this, there is a problem that the stable set hot water temperature cannot be obtained from the beginning of hot water supply because the flow rate change becomes large on the way. .
