The authorized announcement number is CN201697222U. The solar vacuum tube and the ground heating radiating tube are connected to form a circulation loop for heating. The operating cost of the solar heating system described in the above three patented technologies is low. Using the "inexhaustible" solar energy, the operating cost is much lower than that of heating with coal and natural gas, effectively saving users heating expenses, reducing the consumption of non-renewable energy, and achieving the purpose of energy saving and emission reduction.

However, the structures of the above-mentioned several schemes are complicated, and there is heat loss during the process of the hot working medium flowing into the indoor heating facilities, and the heat utilization rate is low.
