PURPOSE: A system for recycling waste hot water is provided to economically recycle the waste hot water by supplying water to a boiler using waste heat in the waste hot water stored in a waste hot water tank and to reduce energy by reducing a driving time of the boiler. CONSTITUTION: A system for recycling waste hot water comprises a cold water tank(10), a boiler(20), a hot water facility(30), a waste hot water tank(40), a waste hot water inlet pipe(50), a waste hot water discharge pipe(60), a heat exchanger(70), and a controller(80). The controller includes a first switching valve(82), a second switching valve(83), and a third switching valve(84). The first switching valve is installed in a pipe conduit of a cold water supply pipe(21) between a cold water inlet pipe(71) and a hot water supply pipe(72). The second switching valve is installed in a pipe conduit of the cold water inlet pipe. The third switching valve is installed in a pipe conduit of the hot water supply pipe. The controller controls a waterway connecting to the boiler by controlling driving of the first switching valve, the second switching valve, and the third switching valve. |
