Solar heat accumulating type floor heating system

The utility model provides a solar heat accumulating type floor heating system, which aims to effectively utilize clean energy and relieve the problem of energy shortage. The solar heat accumulation type floor heating system comprises a solar panel, a heat accumulation water tank, an evaporator, a temperature controller, a geothermal structure and an auxiliary heating device. A cold water structure and a hot water structure which are not communicated are arranged in the heat storage water tank; the solar panel is located over the heat storage water tank. A water circulation system is arrangedin the solar panel and sends cold water in the cold water structure of the heat storage water tank into the solar panel through a heat collection water pump, and hot water flows back into the hot water structure of the heat storage water tank through gravity. Hot water in the heat storage water tank is conveyed to the lower portion of the evaporator through a water pipe, and superheated steam heated by the auxiliary heati
