A.O Smith is a large hot water equipment manufacturer from the United States, with a long history, as early as 1998 to enter the Chinese market, its high-end brand image is deeply rooted in the hearts of the people, and has gained a lot of consumers. Although A.O. Smith's market position in the U.S. industry is controversial and its self-promotion over the years is considered to be exaggerated, it is undeniable that A.O. Smith's products do occupy a significant share of the domestic market. At the AWE exhibition, one of the world's three major electrical appliances and consumer electronics exhibitions, A.O. Smith's "black technology" such as the MAX3.0 Plus reverse osmosis system was impressive and showed outstanding technical strength.
 
A.O. Smith's traditional wall-hung boilers mainly include L1PB-Aplus series, L1PB-C series, L1PB-G series and L1PB-S series, and the condensing furnace has the characteristics of high intelligence, with a power of more than 40kW, which can meet the heating needs of medium and large and villa-type residences, with a multi-temperature zone intelligent linkage control system, which can achieve accurate matching for the characteristics of different areas, and the thermal efficiency can reach 106%, but in all fairness, in terms of high-end condensing furnaces, This value is not outstanding. A.O. Smith's condensing wall-hung boiler is sold for 50,000 or even 90,000 yuan, which is much more expensive than other brands of condensing furnaces.
 
The L1PB26-S features active protection, staged combustion and automatic water replenishment, and is a representative traditional dual-purpose furnace in the L1PB-S series. Although it cannot achieve the extraordinary thermal efficiency value and multiple intelligent effects of a condensing oven, the L1PB26-S still has many safety and functional highlights. It has a built-in separate detection and alarm module, which can detect the carbon monoxide concentration at any time, and start the alarm in time when the concentration exceeds the standard. In view of the complex environment in China, the arc angle fan blade is also specially developed, and the reduced windward angle can avoid excessive dust accumulation in haze days. In order to solve the problem of different power requirements due to the difference in water temperature in winter and summer, the staged combustion technology enables the L1PB26-S to adjust the output power in the range of 15%-100% to achieve high efficiency and low consumption. In addition, the circulating water in the heating system is often discharged after many times due to its closed nature, resulting in low water pressure in the system, L1PB26-S is equipped with a water pressure sensor, which can automatically replenish water regularly to avoid abnormal operation.
 
L1PB26-C is priced at 15818 yuan, which is cheaper than L1PB26-S, and is slightly inferior in performance, lacking automatic hydration and segmented combustion functions, and is not as good as the latter in noise control. In view of the fact that the key components inside the wall-hung boiler will inevitably face problems such as insufficient efficiency and abnormal operation caused by the accumulation of dirt and dirt after long-term use, the intelligent maintenance prompt function of L1PB26-C can monitor the operation status of the machine in real time around the clock to ensure the regular maintenance of the wall-hung boiler.
