HOT-WATER SUPPLY SYSTEM

The present invention is directed to reducing pressure loss in a pipeline between a hot-water tank and a hot-water tap. When the hot-water tank (31) is short of hot-water and the temperature regulation control via heating, in which flowing water in the hot-water supply pipe (2) is heated by the hot-water supply apparatus (10), is initiated, tank controller (50) regulates the mixing ratio, by means of the hot-water flow regulation valve (34) and water flow regulation valve (35), to lower a detection temperature of the mixing temperature sensor (36) from a temperature obtained by subtracting a minimum capacity temperature, which is a temperature increment of the hot-water presumed to increase when heated by the minimum capacity, from the desired hot-water supply temperature by a predefined temperature over a predefined time, and thereafter opens the regulation valve and water flow regulation valve to a maximum opening degree.
