Most of our domestic fireplaces are engaged in home appliances, gas appliances and HVAC industry. It is not difficult to get a fireplace. Especially those who are active in the industry are mostly from famous big companies such as Wanjiale, Wanhe and Mei. And HVAC boiler companies such as the little squirrel. Therefore, at present, China is not afraid of wall-hung boiler technology, and there is no shortage of wall-mounted boilers. Nowadays, most of them are useless, and they are waiting for the arrival of the development of wall-hung boilers.
In the past two or three years, the technical level of domestic accessory parts has undergone great changes, the performance quality has been greatly improved to near the international level, and the price is lower, and the same accessory manufacturers have also increased. Now, except for a few key accessories such as pumps, which rely on imports, most of the accessories have fully met the requirements of the manufacturers of wall-hung boilers, and some have begun to sell back to Europe.
The whole machine production technology of the wall-hung boiler, whether in foreign or domestic production, is actually “stacked wood†plus good quality inspection and testing. What is important here is the performance quality of a standard or semi-standard collaborative accessory. The development of the accessories technology of the wall-hung boiler is also a gradual process. Before 2005, especially before the year of 2003, it was unstable and immature, and there were fewer manufacturers, mostly relying on imports. At this time, whoever boldly uses domestic accessories will suffer, so the performance quality of the domestic wall-hung boilers before this is a lot worse than the domestic assembly of imported or imported accessories. Several brands and enterprises have fallen down, such as Zhongshan. Eternity, Shandong Hengtong, Shenyang Bolong, Huaquan, Dongyang, etc. have become victims of immature accessories.
The technology of the wall-hung boiler is in Europe, and the highest level is also the European model. However, in the face of domestic water quality, gas source conditions, pipeline installation, terminal equipment, consumer level and other issues, some soil and water will not be accepted. Many years of technical research and development and practical installation and use practices have also found some issues that have attracted attention and discussion. For example, the pressure of the bypass valve is lower in the European setting, and the user's pipeline is slightly unobstructed, causing the latter two sets of radiators to be hot. Many Chinese homeless lines also test the electrical performance of imported machines.
