<P>PROBLEM TO BE SOLVED: To provide a cogeneration system and a hot water supply system applied to the cogeneration system capable of filling a storage tank with water in a comparatively short time. <P>SOLUTION: In this cogeneration system 1 constituted by combining a power generator 2 incorporating a fuel cell, and a hot water supply system device 3, a hot water supply flow channel 30 is formed by a series of flow channels from the storage tank 10 to a faucet 34 through a combustion device 31, and a combustion device 31 (auxiliary heat source) is disposed on the way. An auxiliary heating going-water volume sensor is disposed in the flow channel from the storage tank 10 to the combustion device 31. In a tank water filling mode, water is supplied to the storage tank 10 from the water supply flow channel 30, and the tank water filling mode is terminated under a condition that the difference between the water volume detected by a water supply-side water volume sensor and the water volume detected by the auxiliary heating going-water volume sensor is smaller than a specific value as one of conditions. <P>COPYRIGHT: (C)2010,JPO&INPIT |
