Multiple-heat-source hot water system

The invention discloses a multiple-heat-source hot water system which comprises a hot water production system (100), an air-conditioner system (200) and a heating system (300). One end of the hot water production system (100) is connected with a water source, and the other end of the hot water production system (100) is connected with a living hot water supply pipeline. The air-conditioner system (200) used as a heat source of the hot water production system (100) and the heat supply system (300) are respectively connected with the hot water production system (100). The multiple-heat source hot water system is a composite system which is capable of recovering waste heat of air-conditioners and utilizing air source heat pump technology and a centralized heating system, economic, efficient, safe, and reliable, and integrates the functions of supplying living hot water and heating in transition seasons.
