The quality of Baxi wall-hung boiler is poor.

Hello, dear, I'm glad to answer your question. What are the disadvantages of Baxi wall-hung boiler? 1, the later maintenance cost of wall-hung boiler is high, the furnace efficiency will be lower and lower, and it will be more troublesome to replace it within a certain period of time. Generally speaking, the standard life of wall-hung boilers is about 10 years, and the life of good products may be longer. 2. The domestic water provided by the wall-hung boiler may be unstable, and may be hot and cold, because it is not an instant product. 3. The wall-hung boiler is noisy, which has potential safety hazards and may also have environmental pollution problems. Therefore, domestic fireplaces are generally placed in the kitchen or balcony to prevent the wall-hung boiler from leaking or exploding. 4. Daily maintenance is troublesome. Even if the room is unoccupied in winter, it should be kept burning at a low temperature, otherwise it will easily frostbite internal parts and equipment and waste more unnecessary dyes. In the first heating season of the new house, there is a lot of water vapor in the wall, or because the occupancy rate of the community is low, while heating the house, the heat will be conducted to the uninhabited neighbors through the wall, floor and ceiling, which not only affects the heating effect, but also is my answer. I hope I can help you and wish you a happy life.

Hello, dear, it is my pleasure to answer this question for you ~ Baxiyou 147 years of history, during which I have been studying the boiler industry. His safety protection level is 5D, ranking first in the industry, and other brands 4D. Maximum thermal efficiency 109.8%, ranking first. It is one of the three major HVAC systems in Europe. The largest producer. There are no factories in China. It was imported from the original machine. Details can be found in official website. Wei neng is also very good. According to the heating mode of domestic hot water, there are two kinds of wall-hung boilers: instant heating type and volumetric type, that is, hot type is divided into sleeve type and plate-changing type. For example, Weineng is a board-changing type, and Bosch has both. There is a big difference between the two models, so it is best to choose the model first and then the brand. 1. heat exchange principle: the double-tube heat exchanger is the tube-in-tube heat exchanger. The domestic hot water sleeve is nested in the main heat exchanger, and the priority operation of domestic hot water is controlled by the start and stop of the pump. When the domestic hot water is running, the pump stops working, and the domestic hot water in the casing is heated by the first-class high-temperature water in the main heat exchanger. Plate heat exchange type is to heat domestic hot water through plate heat exchanger, and the priority operation of domestic hot water is completed by electric three-way valve. When there is a demand for domestic hot water, the electric three-way valve introduces the primary high-temperature water in the main heat exchanger into the plate heat exchanger to heat the domestic hot water. Second, technical comparison: 1. Comfort of domestic hot water In the process of using domestic hot water, when the user temporarily turns off the production hot water and turns it on again in a short time, because the water in the main heater does not flow, the residual heat of the main heat exchanger and the first-class high-temperature water will continue to heat the domestic hot water in the sleeve. At this time, when the domestic hot water is turned on, there will be high-temperature water for a period of time, which will cause the domestic hot water to be hot and cold, and even burn the user. Plate heat exchange can completely avoid this problem, and it is safe and comfortable to use domestic hot water. 2. Scaling occurs during heating operation, and a stream of high-temperature water will continuously heat the domestic hot water in the shell, resulting in high-temperature scaling; When domestic hot water is used or temporarily stopped, because the water in the main heater does not flow, the residual heat of the main heat exchanger and the first-class high-temperature water will continue to heat the domestic hot water in the shell, which will also cause high-temperature scaling. With the increase of service time, the scale will become thicker and thicker, which will affect the efficiency of wall-hung boilers, especially in areas with hard water quality. Plate-to-plate heat exchange adopts secondary plate heat exchange, and the primary side is a closed system. The water temperature of domestic hot water side is generally limited below 60℃ (the actual water temperature is below 50℃), and it is not easy to scale below 60℃, so it is very convenient to remove and replace the cleaning plate pair. 3. Service life When domestic hot water is used or temporarily stopped, the residual heat of the main heat exchanger cannot be taken away in time because the water in the main heater does not flow, resulting in local high temperature and affecting the service life. Plate heat exchange heat exchange form When the domestic hot water ends, the water pump will run for a period of time, which can effectively avoid local high temperature. 3. Structure and price comparison: the casing machine has no electric three-way valve and no separate domestic hot water heat exchanger, so the structure and control are simple and the price is relatively cheap. As the domestic hot water dish changer and the electric three-way valve are added to the dish changer,
