PROBLEM TO BE SOLVED: To provide a water supply machine which reduces electric power for heating water necessary for making hot water in a hot water tank by providing a preheating tank for preliminarily heating to temperature higher than room temperature at the preceding stage of the hot water tank. SOLUTION: The water supply machine 1 includes a water container 3 for storing water, a transporting means for transporting the water stored in the water container 3 at least by its natural falling or by sucking it, a cold water tank 5 having a cooling means for cooling the water transported by the transporting means for temporarily storing the obtained cold water, a preheating tank 9 for preliminarily heating at least either the water transported by the transporting means or the water supplied from the cold water tank 5, the hot water tank 10 having a heating means for heating the preliminarily heated water supplied from the preheating tank 9 (called "middle temperature water", hereafter) for temporarily storing the obtained hot water, and a conduit 14 for supplying the middle temperature water from the preheating tank 9 to the hot water tank 10.
