PROBLEM TO BE SOLVED: To provide a water server having hot water extraction function capable of preventing high temperature air from jetting from a hot water extraction pipe during hot water extraction.SOLUTION: Provided is a water server configured to introduce drinking water into a hot water tank 9 through a hot water tank supply pipe 10 from a buffer tank (upper tank) 7 disposed above the hot water tank 9. An end 31a of the hot water tank 9 side of a hot water extraction pipe 31 for extracting hot drinking water in the hot water tank 9 to outside is opened at a position having an interval from an upper surface 9a of the hot water tank 9 toward a lower direction. On an upper position of the opening position, a small hole 34 of an in-tank pipe 33 of the hot water tank supply pipe 10 is provided. Thereby when air accumulated on the upper part of the hot water tank 9 is increased, the air is discharged from the small hole 34 of the in-tank pipe 33 toward the buffer tank 7 through the hot water tank supply pipe 10, so that the high temperature air is not introduced into the hot water extraction pipe 31. |
