The invention relates to the technical field of heating, and particularly provides a solar energy, electromagnetic energy and phase-change energy storage coupled heating control system comprising a solar thermal collector, a low-temperature phase-change energy storage water tank, a high-temperature phase-change energy storage water tank, an electromagnetic heater, a heat user side and a PLC. The solar thermal collector communicates with the low-temperature phase-change energy storage water tank through a first circulation pipeline. The low-temperature phase-change energy storage water tank is connected with the high-temperature phase-change energy storage water tank through a heat exchange water return pipe and a conveying pipeline. The high-temperature phase-change energy storage water tank is connected with the heat user side through a second circulation pipeline. The electromagnetic heater is connected with the high-temperature phase-change energy storage water tank through a third circulation pipeline. The solar thermal collector and the electromagnetic heater are connected with the PLC. By means of the heating control system, solar energy and electromagnetic energy are supplied in a stepped manner, it is ensured that the heat supply effect of the heat user side is stable, system operation expenses are extremely low, and the heating system can be safer, can save more energy and is more economical and reasonable.
