Document Type and Number:
Japanese Patent JP5656166
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an instantaneous hot water system capable of returning hot water from a circulating pipe to a hot water storage tank without breaking any thermal stratification of the hot water storage tank.SOLUTION: The instantaneous hot water system 1 includes a circulating pipe 8 which is branched from a hot water feeding pipe 7 and returns to a hot water storage tank 2, and performs the instantaneous hot water circulating operation by using a circulation pump 6 installed in the circulating pipe 8. The instantaneous hot water system includes a temperature sensor 4 for sensing the temperature of the hot water in the circulating pipe 8, and a flow passage changing unit 3 which changes a plurality of paths formed in the hot water storage tank 2 from the circulating pipe 8 to a return port of hot water according to the temperature of hot water to be sensed by the temperature sensor 4. In this constitution, hot water from the circulating pipe 8 can be returned to the hot water storage tank 2 without breaking any thermal stratification of the hot water storage tank 2.
