The energy-saving control method of the floor radiant heating system of the variable-frequency heat pump water heater is characterized by the steps of the control method: the control system establishes the calculated temperature Tgj of the floor water supply and the ambient temperature of the room temperature according to the performance of the variable-frequency heat pump water heater and the heat load characteristics of the heating room. The functional formula between Tw; the control system establishes a functional formula between the room calculated air temperature Tnj and the ambient temperature Tw based on the thermal comfort of the human body; the control system adjusts the conversion according to the difference between the actual water supply temperature Tgs and the supply calculated temperature Tgj The compressor speed of the heat pump water heater makes the actual calculated water temperature Tgs and the calculated water temperature Tgj converge; the control system adjusts the opening of the three-way proportional control valve according to the difference between the actual room air temperature Tns and the room calculated air temperature Tnj, Make the room actual air temperature Tns and the room calculated air temperature Tnj converge. It has the advantages of higher energy efficiency of heat pump water heater, energy saving in operation and better thermal comfort of human body, etc.
