In the global wall-hung boiler market, Vaillant occupies a 27% share, and like Bosch and Viessmann, it has become an outstanding representative of the German wall-hung boiler brand with excellent quality and performance, and is a leading manufacturer of heating and domestic hot water equipment in Europe, one of the largest manufacturers of household gas wall-hung boilers, and the inventor of the first gas wall-hung boiler. Vaillant has 11 factories and product R&D centers around the world, and its wall-hung boilers are all subject to rigorous testing in advanced product laboratories before they can be put into the market, and at the same time, 4% of its revenue has been spent on technology research and development for many years, which is higher than the industry average. In addition to researching advanced technology, Vaillant has launched a number of wall-hung boiler products that have won the Red Dot Design Award, and have gained a lot of support for their beautiful and elegant appearance.
 
Like Bosch, Vaillant's product line is clearly divided into two types: condensing furnaces and conventional furnaces, with the main domestic condensing furnaces being ecoTEC pro, ecoTEC plus VUW and ecoTEC plus VU, all of which offer several power options to suit different sizes of housing. Among them, ecoTEC plus VUW and ecoTEC plus are imported from Germany and have a high price. The selection of conventional products is more abundant, with twice as many styles than condensing furnaces, including high-end imported products such as turboTEC plus VUW and turboTEC pro VUW, as well as balcony type wall-hung boilers that are specially customized for the southern Chinese environment and can be used for outdoor installation, and the installation ambient temperature can be as low as -10°C.
 
L1PB27-VUW 242/5-3 (H· CN) supports 24kW power input, heating area of 60-150 square meters, and the price is nearly 28,000 yuan. Like the Bosch New Eurostar, it uses an LCD screen, with a soft blue backlight and is not easy to hurt the eyes, and the water pump that can automatically adjust the speed fully adapts to the needs of different heat dissipation systems, and is an external structure. This product also has a high level of intelligence, and can be connected to mobile phones and computers to achieve remote control. Vaillant's unique "four-point temperature control" technology can also ensure that the temperature control accuracy of hot water is controlled within the error of 0.5°C, and the temperature control effect is first-class. In addition, the turboTEC pro VUW has a fast heating function for domestic water, so users don't have to wait too long to use hot water and save water consumption.
 
Among Vaillant's condensing wall-hung boilers, the ecoTEC plus VUW series is a high-end dual-purpose furnace that meets both heating and domestic hot water needs, with four power options of 20, 25, 30 and 35 kW for different room sizes. The condensing wall-hung boiler adopts the full premix ratio adjustment method, so as to recover and utilize the waste heat in the flue gas, which has a higher thermal efficiency than the conventional wall-hung boiler. The ecoTEC plus VUW is equipped with latent heat recovery technology with a thermal efficiency of 108%, and uses the same "four-point temperature control" technology as the turboTEC pro VUW, with an additional function to prevent dry burning.
 
EcoTEC pro is a condensing series product specially developed and designed by Vaillant for the Chinese market, and its main burner is made of stainless steel, which has strong corrosion resistance, high product life, and is equipped with Vaillant's unique Aqua-condense system, which is highly efficient and energy-saving.
 
Vaillon adopts the process of paying a deposit, making an appointment for design, and installing and paying on the e-commerce platform, which is prone to inflated prices. For most Vaillant products, especially condensing furnaces, it is better to choose offline channels to buy.
