Title:
HOT WATER SUPPLY DEVICE
Document Type and Number:
Japanese Patent JP2015107202
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress a decrease in hot water temperature in the process of supplying hot water in a hot water storage tank to a supply destination.SOLUTION: A hot water discharge pipe 41 is a double pipe including an inner pipe 411 and an outer pipe 412. The inner pipe 411 extends in the vertical direction in a hot water storage tank 14 and penetrates a bottom part 14a of the hot water storage tank 14, and the lower end part of the inner pipe projects downward from the bottom part 14a. The outer pipe 412 covers the outer peripheral surface of the inner pipe 411 in the hot water storage tank 14. A heat insulation layer 415 is formed between the outer pipe 412 and the inner pipe 411 in the hot water storage tank 14. The lower end part of the inner pipe 411 extends into a distribution pipeline 42. The heat conductivity of the inner pipe 411 is higher than that of the outer pipe 412. The outer surface of the distribution pipeline 42 is covered with a distribution pipeline upper part heat insulation material 71 and a distribution pipeline lower part heat insulation material 72. A distribution pipeline heater 73 can heat the distribution pipeline 42.
