The invention discloses a heating system, comprising a heat source (1) for supplying a high-temperature working medium and heating tail ends with at least more than two forms, wherein the heating tail ends with various forms are connected in parallel, are connected in series or are arranged in a combined parallel and serial connection manner, and are respectively communicated with the heat source (1) through pipelines so as to form a loop; and the heating tail ends specially are at least two of a heat radiator, a heating coil pipe and an air blower coil pipe. Compared with the prior art, in the heating system provided by the invention, on one hand, the heating tail ends with the corresponding forms can be arranged according to rooms with different functions, and the property indexes of comfort, warming speed and the like can be met simultaneously, so that the heating requirements of the rooms with the different functions can be met, and the flexible arrangement is realized; and on the other hand, the heating tail ends with various forms use one heat source, so that the initial system of the system is greatly reduced, and the heating cost is effectively controlled.
