HOT WATER STORAGE-TYPE HOT WATER SUPPLY SYSTEM

WIPO Patent Application WO/2019/207725

A1

Provided is a hot water storage-type hot water supply system in which a passageway for hot water from a water source to a hot water supply terminal is formed by a plurality of hot water storage-type hot water suppliers which are connected in series, and in which energy-saving performance is not impaired. A hot water storage-type hot water supply system wherein: each hot water storage-type hot water supplier (10) comprises water supply piping (31) which guides hot water from a water source to a hot water supply heat exchanger (21), hot water supply piping (34) which guides the hot water from the hot water supply heat exchanger (21) to a hot water supply terminal, a water supply thermistor (33) provided to the water supply piping (31), and a hot water supply heat source pump (24) which circulates the hot water between a hot water storage tank (11) and the hot water supply heat exchanger (21); the hot water supply piping (34) of an upstream hot water storage-type hot water supplier (10) is connected to the water supply piping (31) of a downstream hot water storage-type hot water supplier (10); and a control unit (50) stops operation of the hot water supply heat source pump (24) if the water supply temperature detected by the water supply thermistor (33) during a hot water supply operation is at or above a temperature threshold value.
