The invention discloses a solar ground surface and kang surface combined heating system. The solar ground surface and kang surface combined heating system comprises a solar heat collecting system, a heat storage system, a kang surface heating system, a ground surface heating system and a control system, wherein the heat collecting system collects solar radiation heat which is then output and stored in the heat storage system, and operation time and supplied heat amount of independent heat supply of the ground surface and kang surface heating system are set through the control system so as to meet the heat demand of people. When a user moves in a room in the daytime, the ground surface heating system supplies heat to the room so as to meet the indoor temperature demand; when the user is in the sleeping state at night, the kang surface heating system provides comfortable quilt temperature. The ground surface and kang surface time-division partition-area heating mode is adopted, and the heat is supplied according to different heat demands in different states and people moving areas in the daytime or at night; the energy consumption of a building is reduced; system scale and cost are reduced; the application is convenient; control is easy; the operability is high; the solar ground surface and kang surface combined heating system is good in economic and social benefits when applied to and popularized in solar heating buildings of villages and small towns.
