We're looking forward to working with you in the future, in the eyes of endless business opportunities. With the heavy waste of centralized heating energy, which has created conditions for the heating of households, the need for individual heating has increased in the southern region, as the coastal provinces along the river are wet and cold in the southern part of the country and the majority of the population is no longer able to meet their needs. With increasing environmental pollution, "coal-gas conversion" has been rapidly extended throughout the country as an important initiative. "coal-modified gas" is more concentrated in the civilian sector and is being promoted through producer tenders and user-benefit models, leading to the development of the domestic wall-mounted industry. In the market, the domestic fence grew from a total of 350,000 in 2008 to a total of 4. 26 million in 2020, with an explosive increase, accompanied by improvements in the industry's standardized system, the heating sector has matured and conditions are in place for steady development in the future。
