Abstract

PURPOSE:To prevent the freezing trouble of an outside pipeline from occurring and to realize an immediate hot water supply by providing a trace hot water circuit for heat insulating and heating of an outside hot water supply pipe and a water supply pipe which are connected to the main body of the hot water storage type hot water supplier. CONSTITUTION:Hot water in a trace hot water circuit C is supplied from an expansion tank 21 to a heat exchanger 20 for trace hot water by means of a circulating pump for trace hot water. After being heated and increased in the temperature with hot water stored within a hot water storage tank 3, the hot water is used for heat insulating and heating an outside hot water supply pipe 15 and an outside water supply pipe 13 through a trace hot water pouring pipe 23. Then, cooled trace hot water returns back to the expansion tank 21 through a trace return pipe 24, and its circulation cycle is repeated again by means of the pump for circulating trace hot water. Further, a system of the outside water supply pipe 13 in the trace hot water circuit C is closed when there is no possibility of freezing in summer and intermediate seasons by a valve 28 provided in the intermediate of a trace hot water return pipe 24.
