PURPOSE: A device for saving hot water is provided to reduce water waste by forcefully flowing hot water in a hot water line into a cool water line when hot water is used. CONSTITUTION: A device for saving hot water is composed as follows. When a power source(11) is operated, a user sets temperature in a controller(10). A central processing unit(9) reads current water temperature data from a water temperature sensor(6) based on the set data. When current water temperature is lower than the set water temperature, an electronic valve(7) is opened, and a circulation motor(8) is operated. Water in a hot water line(1) is rotated toward a cool water line(5) through connection lines(2,3,4). |
