Solar heating apparatus used in winter

The utility model relates to a solar heating device used in winter, which relates to the technical field of solar heating utilization. The utility model comprises a vacuum pipe heat collector (1), a heat insulating water tank (2) provided with an auxiliary electric heating device, a temperature control device (4), a water outlet pipe (5) (also as a water supply pipe) connected with the heat insulating water tank, and a water return pipe (6) (also as a water overflow pipe). The utility model has the technical scheme that a plurality of groups of radiators (11) are additionally connected to the position between the water outlet pipe and the water return pipe; or the water outlet pipe and the water return pipe are connected with a water separator (15) which is connected with a plurality of ground warming pipe radiators (16) in parallel; a water pump (9) and a temperature control device (19) are connected in series to the upper position of the water outlet pipe (5) or the water return pipe (6). The utility model has the advantages that a vacuum pipe water heater provided with the auxiliary electric heating device is connected with a radiating device (a heating radiator) or the ground warming pipe radiators of a heat radiating device, and the water pump is additionally arranged on the pipeline of the system, so a forced circulation system is formed, solar energy is used as the main energy, auxiliary electrical heating is adopted in cloudy rainy days or especially cold days and exhaustless solar energy is fully used. The utility model also has the advantages of ideal heating effect, cleanness, and environmental protection and is a significant improvement for coal fired gas heating equipment which wastes energy resource and pollutes the environment.
