The first embodiment:

a solar heating system shown in fig. 1 includes a solar collector 1 for converting solar energy into thermal energy and a holding tank 2 for storing hot water. The solar heat collector 1 adopts a vacuum tube solar heat collector, and a water outlet pipe 101 of the solar heat collector is communicated with a water tank water inlet pipe 201 of the heat preservation water tank 2 through a first electromagnetic valve 101 a. The lower part of the heat preservation water tank 2 is provided with a water tank outlet pipe 202 communicated with a water inlet pipe of a household heater, the water tank outlet pipe 202 is provided with a circulating pump 4, and hot water flows in the whole heating system under the action of the circulating pump 4. The water return pipe 102 of the solar heat collector 1 is communicated with the household water return pipe 5 for heating the household through a second electromagnetic valve 102 a. The inside of holding water box 2 is provided with level sensor 203, and after the water level in the holding water box was less than certain limit, water was injected to the water tank through the water injection pipe 204 that sets up at the top of holding water box 2, is provided with third solenoid valve 204a on water injection pipe 204 and realizes the control to the water injection process. In order to realize continuous heating when no sunlight exists, the solar power generation device 8 is arranged at the top of a house of a resident and is a conventional device, common technicians in the field can select the conventional device from existing products, the solar power generation device is mainly used for converting solar energy into electric energy and storing the electric energy, the solar power generation device is connected with the electric heater 206 below the inside of the heat preservation water tank 2, the water source in the heat preservation water tank is heated by the electric energy stored by the solar power generation device when no sunlight exists at night, and the heating continuity is ensured.

The second embodiment:

in the second embodiment, a water outlet tee pipe 3 is arranged on a pipeline of the first electromagnetic valve 101a on the side away from the solar heat collector 1, and the water outlet tee pipe 3 connects the water outlet pipe 101, the water tank inlet pipe 201 and one end of the water tank return pipe 7. A water return three-way pipe fitting 6 is arranged on a pipeline on one side, away from the solar heat collector 1, of the second electromagnetic valve 102a, and the water return pipe 102, the household water return pipe 5 and the other end of the water tank water return pipe 7 are communicated through the water return three-way pipe fitting 6. A fourth electromagnetic valve 701 is arranged on the water tank return pipe 7, and the on-off of the water tank return pipe 7 is controlled through the fourth electromagnetic valve 701.

In both embodiments, the inside of the holding water tank 2 may be provided with a temperature sensor 205, and when the temperature of water is detected to be lower than a certain set temperature, the water in the holding water tank may be heated by the electric heater 206 under electrical control to ensure the heating temperature.

Next, the operation of the solar heating system according to the present invention will be described by taking a second embodiment as an example.

When sunlight exists in the daytime, the first electromagnetic valve 101a and the second electromagnetic valve 102a are opened, the fourth electromagnetic valve 701 is closed, at the moment, hot water in the solar thermal collector 1 enters the heat preservation water tank 2 through the water outlet pipe 101 and the water tank inlet pipe 201, enters a resident for circulation for a week under the action of the circulating pump 4, flows out of the resident water return pipe 5, and returns to the solar thermal collector 1 through the water return pipe 102 to be heated again. At this time, since the fourth electromagnetic valve 701 is in a closed state, no water flows through the water tank return pipe 7, and hot water circulates only among the solar heat collector, the heat-insulating water tank, and the household.

When there is no sunlight at night, the solar heat collector cannot heat water by using sunlight, and therefore, in order to prevent heat from being dissipated in the solar heat collector during hot water circulation, the first electromagnetic valve 101a and the second electromagnetic valve 102a need to be closed and the solar heat collector needs to be disconnected from the heating system. The fourth electromagnetic valve 701 is opened, the water return pipe 7 of the water tank is connected into the heating system, and at the moment, hot water in the heat-preservation water tank circulates between the heat-preservation water tank and the resident. When the temperature sensor 205 detects that the temperature of water is lower than a certain set temperature, the electric energy stored in the solar power generation device can be released under the electrical control, and the water in the heat preservation water tank is heated by the electric heater 206, so as to ensure the heating temperature.
