PROBLEM TO BE SOLVED: To provide a hot water apparatus wherein in the case of feeding a small amount of hot water, wherein water is not supplied by a person, a waiting time can be reduced, and a maximum amount of stored hot water can be suppressed to that heat insulating power can be reduced. SOLUTION: The hot water apparatus includes a hot water storage vessel 14 for storing hot water, a flow-in pipe 5, one of the ends thereof is connected to a city water pipe, the other end being disposed at the bottom of the vessel 14, heating means 6, 12 for heating water, a first temperature sensing means 7 for detecting temperature of the vessel 14, a flow-out pipe 11 which is disposed on a side of the vessel 14 to convey hot water to a delivery part, and an opening 13 formed on the top of the vessel 14 to vent steam. Further, the pipe 5 has a flow rate adjusting means 3 to adjust the flow rate and a flow rate sensing means 4 to detect the flow rate, and the pipe 11 is connected to a pump 9 and has a second temperature sensing means 10 to sense the temperature of hot water delivered and a control means 16 to control the means 3, heating means 6, 12, and pump 9. The means 16 allows hot water to be delivered until the hot water, the amount of which is larger than a first predetermined amount, is heated to a predetermined temperature.
