Founded in 1992, Wanjiale Co., Ltd. is a large-scale enterprise with a wide range of kitchen and bathroom appliances, and wall-hung boilers are the core business of Wanjiale heating system. Wanjiale has participated in the formulation of national standards related to wall-hung boilers, and has obtained more than 200 patents for various technology research and development.
 
Wanjiale is known for its constant temperature combustion and condensation technology. Among them, the condensing technology makes the gas fully pre-mixed with the air before entering the combustion chamber, and the integrated condensing heat exchanger increases the heat exchange area, thereby effectively improving the combustion efficiency. For example, Wanjiale's U series condensing wall-hung boiler, the thermal efficiency of this series of products can reach 106%, even compared with the flagship machine of foreign high-end brands, it is not inferior, compared with ordinary styles of wall-hung boilers, its efficiency is improved by more than 10%.
 
L1PB38-19P2 is a Wanjiale wall-hung boiler with excellent performance, its thermal efficiency has reached the national level 2 energy efficiency standard, the price is 7898 yuan, and the cost performance advantage is outstanding. This product has a built-in unique dual-pump tandem heating system, which can intelligently control the water flow speed, and the stepped combustion technology can also avoid pipeline damage caused by excessive heating, effectively protecting the machine and prolonging its service life. In addition to this, the use of smart sensors and microcomputer operation enables precise control of the gas volume and bath water temperature. This product also has a bright spot in terms of quiet performance, and the three-layer cavity structure helps to reduce operating noise.
