Title:
HOT-WATER SUPPLY SYSTEM
Document Type and Number:
Japanese Patent JP2018155470
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a hot-water supply system capable of achieving both instantaneous property of hot-water supply to each of a plurality of hot-water supply load systems, and energy saving.SOLUTION: A hot-water supply system 1 includes: circulation switching means 71a-71c for switching whether hot water is circulated or not to each of a plurality of hot-water supply load systems 311a-311c; sensing means 511a-511c for sensing a user who approaches each of the plurality of hot-water supply load systems 311a-311c by detecting an identification body 8; and a control means 100 for controlling a circulation pump 32 and the circulation switching means 71a-71c so as to circulate hot water to the hot-water supply load systems when the sensing means 511a-511c sense the user. A sensing distance as a distance between the user and the hot water load system which the user uses when the circulation pump 32 is started according to the fact that the sensing means 511a-511c sense the user, can be set so as to be different between the plurality of hot-water supply load systems 311a-311c.SELECTED DRAWING: Figure 1
