The utility model belongs to the technical field of anti-explosion tube systems and particularly relates to a heating safety protection system. A circulation water pipe is arranged on a heating water tank, two ends of the circulation water pipe are respectively connected with the bottom and a side face of the heating water tank, and a circulation water pump and a cooling fin are arranged on the circulation water pipe. A branch water pipe is arranged on the circulation water pipe between the circulation water pump and the cooling fin, the lower end of the branch water pipe is connected with a water storage tank, and a magnetic valve is arranged on the branch water pipe. An upper water pipe is arranged on a side face of the heating water tank, the lower end of the upper water pipe is located on the lower portion of the inside of the water storage tank, and an upper water pump is arranged on the upper water pipe. The water storage tank is located below the heating water tank. A thermoelectric couple extends into the heating water tank from the upper portion of the heating water tank. A control device is connected with the thermoelectric couple, the circulation water pump, the magnetic valve and the upper water pump. According to the heating safety protection system, automatic recession of water is achieved by means of the control device before water temperature is higher than the freezing point, and therefore cracking of a solar collector tube and the circulation water pipe is effectively prevented.
