“…MECH is an effective method to improve energy utilization and system stability. According to the energy demand and geographic resource conditions of rural buildings in China, various forms of clean energy are used, for instance solar energy, ASHP, biomass and ground source heat pumps etc [9]. It can solve the problem of mismatch and instability between supply and demand of a single renewable energy system and increase the operational efficiency of heating system.…”

Winter heating in rural areas has always been an issue of great concern to the State. In China, traditional heating methods mainly use coal-fired boilers or heating stoves, however, coal burning has caused serious environmental pollution and air quality problems. In order to improve heating conditions and reduce environmental pollution, some rural areas have begun to try multi-energy complementary heating (MECH) system, which improves heating efficiency by comprehensively utilizing solar energy, biomass energy, ground source heat pump, air source heat pump (ASHP). However, due to poor economic conditions, the actual operation faces various factors and challenges. In order to solve these problems, this paper provides a systematic review of the research on MECH systems in rural areas in China in recent years. First, it summarizes the existing MECH systems, including various technologies such as solar-ASHP heating, solar-biogas heating, and ground source heat pump-solar heating, and lists their advantages and disadvantages in detail. Secondly, the effects of MECH systems in practical applications are discussed through case studies. Finally, recommendations for promoting MECH technologies are presented to facilitate the development of MECH systems in rural areas. The study contributes to the development of MECH system, which helps to improve rural heating conditions and reduce environmental pollution.
