Founded in 1917, Viessmann is now the world's leading heating equipment manufacturer, as early as Bosch entered the Chinese market in 1997, and quickly established a sales network and supporting service system in the country, Shanghai Pudong Airport and Hong Kong Disneyland have adopted Viessmann's heating system. Viessmann products are known for their beautiful appearance and outstanding design, and have won many iF and Red Dot Design Awards, among which the Vitodens 100-W has also won the prestigious iF Design Gold Award.
 
Viessmann gas wall-hung boiler has been selected as the best product by the well-known German consumer testing organization "Stiftung Warentest" for many times, and its excellent technical strength is enough to support its independent production of the main components inside the wall-hung boiler, such as heat exchanger and burner. At present, all Viessmann condensing products sold on the market, whether imported or assembled in China, have core components produced in Viessmann's factory in Germany, which is something that most brands cannot do.
 
Viessmann condensing pot uses the original Inox radial heat exchanger, made of high-quality titanium alloy stainless steel, square flow channel and precise gap design to transfer high heat value, improve the utilization rate of calorific value while ensuring the reliability of the product, and can also save a sum of money in years of use. Viessmann's self-developed MatriX cylindrical burner is also impressive, as it allows gas and air to be mixed more thoroughly and the service life of the product is extended.
 
Viessmann's main products include 100, 200 and 300 series, and there are many models imported from Germany. Vitodens 100-W B1JE is made in China and is available in 19, 26 and 35 kW for different room types. Among them, the products with a power of 26 and 35 kW are divided into two types: dual-purpose furnaces and single heating furnaces, which need to be carefully distinguished. This is a condensing product specially created by Viessmann for the Chinese market, with two modes of winter/summer, which can fully cope with the special environmental conditions of large temperature differences in different seasons in China, and is very convenient to use.
 
In response to the fact that safety is a concern for every consumer, the Vitodens 100-W B1JE provides multiple protection against freezing, overheating, water pressure, and self-diagnosis in the event of a malfunction. The price of Vitodens 100-W B1JE's 26kW power dual-purpose furnace is 16,372 yuan, which is quite cost-effective in terms of the price of condensing products that are generally more than 20,000 yuan.
 
The Vitopen 100-W A1JE is available in 6 models of 24.8, 30, 36kW dual-purpose or single heating, and like the Vitodens 100-W B1JE, it is a wall-hung boiler specially designed for the Chinese environment, with a choice of winter/summer modes. The product has been optimized for ease of use, with a clear and soft LCD screen and the ability to set the runtime as needed. The main feature of this product is the strong and quiet performance, and the built-in high-quality fan can control the noise to 45 decibels, so even babies can stay in it until they fall asleep. It should be noted that compared to the Vitodens 100-W B1JE, the Vitopen 100-W A1JE is not a condenser, but the price is still over 10,000 yuan, which is slightly expensive.
