Gas wall-hung boilers (hereinafter referred to as "wall-hung boilers") have been developed for many years, integrating the bathing function of traditional water heaters and the heating function of traditional boilers. These years have also been regarded as a branch of the water heater industry in the industry. However, compared with traditional water heaters, wall-hung boilers have only been developed in China for more than 20 years, and most consumers still know little about them. Wall-hung boilers originated in Europe. Since the 1990s, some European and Korean brands have entered the Chinese market and gradually expanded their market share advantages. However, the development of wall-hung boilers in recent years has mainly focused on the engineering market, and has played its advantages under the catalysis of coal-to-gas policies and refined decoration. In recent years, the topic of heating in the South has attracted people’s attention. The heating cycle is relatively short, and the heating period in some areas is only 40 days. Considering the complexity of heating equipment construction, it is not suitable for central heating. Wall-hung boiler heating has become the most popular heating system in the South. Excellent solution. In addition to southern fine decoration, consumer demand for wall-hung boilers at home has also begun to appear. In the process of communicating with reporters, many wall-hung boiler practitioners believed that the future of wall-hung boilers is not in the coal-to-coal reform market, but in the retail market. Under the influence of the epidemic, the wall-hung boiler industry has been affected in both the engineering market and the retail market this year. According to industry online data, the sales of wall-hung boilers in Q1 this year were 230,800 units, a year-on-year decrease of 36.67%; among them, the sales of condensing wall-hung boilers (including secondary heat exchange) were 23,500 units, a year-on-year decrease of 66.03%. Gas Engineering) 169,300 units, a year-on-year decrease of 24.07%, and retail sales of 61,500 units, a year-on-year decrease of 56.55%. Test the water live sales The wall-hung boiler market is subject to short-term fluctuations under the influence of policies and the property market, but overall, the market will still be on the rise for a long time. Even if the sudden outbreak of the epidemic this year has a major impact on retail market sales, especially offline channel sales, the overall market growth direction will not change in the long run. On the one hand, the country’s determination and intensity on the use of clean energy have not changed, and the epidemic has not affected the process of converting coal to gas and electricity in most areas; on the other hand, the rapid development of e-commerce during the epidemic has made more users recognize To learn about and purchase wall-hung boiler products online. Although the retail market for wall-hung boilers tends to be offline, under the influence of the epidemic this year, wall-hung boiler companies have also begun to try to break through the bottleneck of product sales through live online sales. It is understood that Qingdong Nabian has previously launched a live sales of wall-hung boilers in Xinjiang and Hebei, which has achieved good results. Bosch is also experimenting with product sales in this form this year. Previously, many wall-hung boiler companies had low investment in the online market. This year's changes in user consumption habits are also driving these companies to accelerate channel changes. Live streaming is the most popular online traffic aggregation and product promotion method nowadays. If you want to bring dividends to sales through this method, you need a relatively long-term cultivation and planning of the brand. Multiple pain points to be solved At present, wall-hung boiler products need to face localization problems that are completely different from those in the European market. The geographical and climatic conditions of different regions in China are obviously different, and the usage habits of residents are also different. The wall-hung boiler is different from ordinary household appliances, and its operation is also affected by the quality of the local gas source, water quality, climatic conditions, and building structure. How to adapt the wall-hung boiler products to various use conditions and ensure the safe, stable, normal and efficient operation of wall-hung boiler products is a problem that every wall-hung boiler manufacturer must face. Manufacturers of wall-hung boilers need to make in-depth research and understanding of the Chinese market and application environment while using mature technologies in the heating industry in advanced regions to provide professional solutions to specific problems, rather than blindly copying the R&D experience in these regions. It is understood that Bosch will introduce wall-hung boiler products that are adapted to the Chi

Wall-hung boilers are dual-purpose heating equipment for heating and bathing. Its core problem is its service life, and the biggest factor affecting its service life is the problem of scale. Everyone knows that scale is formed because the temperature difference is too large, especially when we use domestic hot water, because we need to continuously fill in new water, the fouling rate of the heat exchanger is greatly increased. As the scale attached to the inner wall of the heat exchanger continues to thicken, the heat exchange efficiency of the wall-hung boiler will also be greatly reduced. The main manifestations are the increase in the gas consumption of the wall-hung boiler, insufficient heating, and hot and cold sanitary hot water. Symptoms such as decreased water volume. If the heat exchange components of the wall-hung boiler are finally kept running under such a high-load state, the damage to the wall-hung boiler is very severe and its service life is seriously affected. Therefore, any gas boiler must be cleaned and maintained after two to three years of use. After a winter of high-load operation, the heat exchanger and other components inside the wall-hung boiler will be full of scale. Running the wall-hung boiler in this state will not only affect its service life, but also increase gas consumption. It causes a waste of energy and brings losses to the individual's economy. So how do you tell if your wall-hung boiler should be cleaned? 1. The wall-hung boiler has been used continuously for more than two heating seasons. 2. It is obvious that the gas consumption of the wall-hung boiler has increased than before. 3. The heating time of the wall-hung boiler increases, the sanitary hot water is cold and hot, and the hot water output per unit time decreases. 4. The operating sound of the wall-hung boiler increases, and there will be abnormal noises from time to time. Wall-hung boiler cleaning operation process Note: The following operations must be carried out under the guidance of professional and technical personnel! 1. Open the upper cover of the washing machine, take out the accessories in the liquid distribution tank, wrap the three separation valves with sealing tapes, screw them on the water supply connector on the end of the body, and connect the drain connector of the return connector box to make it closed status. 2. Untie the joints of the heating system and hot water system of the wall-hung boiler, and use the connecting pipes to respectively connect the water supply pipeline, the return water pipeline and the upper return water joint of the washing machine. 3. Plug in the power cord of the cleaning equipment. 4. Pour water into the mixing tank to two-thirds of the mixing tank. 5. Open the water separation valve and return water separation valve, turn on the power switch of the washing machine, and start the water circulation of the circulating pump. If the liquid level in the tank drops, it needs to be added again until the specified water level is stable. 6. Start the red power switch (showing that the red power indicator light is on, the temperature controller shows OFF, and then press the green start switch to check whether the water in the dosing tank is circulating (if the water in the dosing tank does not circulate, starting is prohibited) Temperature controller switch), after two minutes of normal circulation, press the heating button in the temperature controller to turn ON, and the temperature of the water will be displayed at the same time. When the temperature is heated to 30℃, add the big bag of cleaning agent to the mixing tank and stir to melt the cycle. The factory rated temperature of this machine is 45℃, when the water temperature reaches 45℃, the thermostat will disconnect and stop heating, and the heater will automatically feed water when the water temperature is lower than 40℃. 7. The cleaning cycle depends on the color change of the cleaning fluid, generally from clear to muddy, from light to thick, until the color no longer darkens, the time is about 1 to 1.5 hours, after confirming that it is clean, turn off the power switch. Stop the loop. Use the sewage pipe to drain the cleaning liquid, refill with clean water, start the cleaning machine to cycle for 5-10 minutes, then drain the water, and the cleaning is over. 8. After cleaning, you must first turn off the temperature controller (the screen displays OFF), then turn off the start switch, and then turn off the power switch. 9. Remove the connecting pipes and restore the system. Precautions 1. The circulating pump is not a self-priming pump. When filling the water, fill the pump head with water, otherwise there will be air in the pump and cleaning cannot be carried out. 2. It is forbidden to start the cycle switch without water to prevent damage to the machine without load. 3. It is forbidden to start the temperature controller switch without water and without circulation. 4. During the opera
