Document Type and Number:
Japanese Patent JP2023119623
Kind Code:
A
Abstract:
To provide a hot water supply system capable of securely delivering hot water from a hot water delivery terminal.SOLUTION: A hot water supply system has: an instantaneous hot water circulation circuit for circulating hot water between a hot water supply source and a hot water delivery terminal 400; instantaneous hot water temperature detection means 74 for detecting a temperature of hot water in the instantaneous hot water circulation circuit; and an instantaneous hot water circulation pump 73 provided in the instantaneous hot water circulation circuit. After an operation of the instantaneous hot water circulation pump 73 is started, when the temperature of the hot water in the instantaneous hot water circulation circuit becomes a predetermined instantaneous hot water stop temperature or more and an operating time from the start of the operation of the instantaneous hot water circulation pump 73 becomes a predetermined instantaneous hot water stop time or more, the instantaneous hot water circulation pump 73 is stopped.SELECTED DRAWING: Figure 1
