Wanhe is a well-established heating equipment manufacturing enterprise in China, with a wide range of business coverage, with seven major manufacturing bases in major cities across the country, covering an area of more than 1 million square meters, especially in the field of gas appliances. The wall-hung boiler is a core component of Wanhe's heating business. With the first GAA gas self-adaptation technology in China, Wanhe wall-hung boiler has been widely recognized by the market and is in a leading position in the industry, and its products are also exported to European countries.
 
The price of Wanhe wall-hung boiler is divided into eight series from low to high: A, Y, H, S, T, V, U, Q, the first four series are level 2 energy efficiency, and the others are level 1 energy efficiency. The Q series is the most high-end Class 1 energy efficient condensing furnace, offering three power options of 25kW, 34kW and 57kW, with a thermal efficiency of 108%, comparable to Ariston's flagship condensing equipment.
 
Q25B2 is a low-power product in the Q series, with a price of 28,000 yuan. Its key component, the heat exchanger, is made of weld-free technology, which has better performance in corrosion and compression resistance. The shell is made of PPX 830 composite material, which is more durable and quieter than ordinary metal, and with a DC inverter fan, the noise generated during operation is controlled at 36 decibels, so that even babies can sleep comfortably. The core components of the product, such as the metal fiber burner and the extended plate heat exchanger, are made of high-quality materials and can be connected directly to the parallel boiler system and used with the thermostat for easy use.
 
V18B4 is priced at 14,500 yuan, and the thermal efficiency is 104%, although it is slightly inferior to Q25B2, but it also meets the national level 1 energy efficiency standard. The unique alloy tempered glass panel makes this wall-hung boiler recognizable, and the main highlight of this product is the provision of multiple modes, making it able to meet the user-friendly needs of different scenes. After the user turns on the Auto mode, the system will automatically adjust the temperature according to the environmental conditions, so that the room is always at a constant temperature. The V18B4 can also be switched to night mode, which reduces the energy consumption of the wall-hung boiler and reduces the operating noise level.
