According to analysts from related industries, ground source heat pump technology has been recognized by more and more people because of its advantages of environmental protection, energy saving and clean, and simple control equipment. However, in fact, the development of ground source heat pump technology in rural areas in China is not ideal. The energy consumption of rural households in some cities has basically completed the transformation from primary energy to commodity energy.

According to related investigations, rural households in Beijing’s surrounding countryside use an average of 2.9 tons of coal per year, use 920kW/h of electricity, and use 3 to 4 cans of liquefied gas. In the total household energy consumption, coal accounts for 74%, electricity accounts for 13%, liquefied gas accounts for 8%, and straw and other biomass energy accounts for only 5%. The energy consumption of 2.9 tons of coal used by rural households for heating is 2.3 tons, which is close to 80%. According to calorie conversion, about 60% of household energy consumption is used for heating in winter, and 78% of households believe that heating burden is heavy. It is understood that the situation of energy consumption in rural areas surrounding Dalian is basically the same as that in Beijing.

The problems encountered in the promotion of geothermal heat in rural areas are mainly due to the high initial investment in ground source heat pump systems. The cost per unit of single-unit residential buildings is usually around 350 to 400 yuan. All of them are in the range of RMB 150-200, resulting in a situation where rural residents cannot use them. At the same time, the insulation measures of rural buildings are generally not good, resulting in large heat losses, which in turn cause high heating loads and high operating costs. According to the major market survey, in addition, as water and ground source heat pump systems are mostly used in public buildings, the use of the system involves the participation of professional technicians. When ordinary families use them, especially when they are used by rural households, it will inevitably cause operational mistakes, and in severe cases it will lead to system damage.

Persons in related industries suggest that if problems are to be solved, they should establish professional organizations or instruct professional departments to conduct unified planning and research on the implementation of geo-energy technologies in some urban rural areas and urban fringe areas, and come up with implementation plans, programs, and policies. Or take out certain areas and land plots to demonstrate; for the development units that use energy and new energy technologies in urban edge development projects or rural homestead renovation projects, give preferential treatment in terms of land price and supporting facilities; at the same time, residents’ heating costs are not Change; For rural households using ground-source heat pumps in rural homes and greenhouses, according to the amount of investment or heating area according to the policy of home appliances to the countryside, given a certain amount of subsidies.
