Outdated Product
An energy-efficient German single-circuit heating gas boiler with a closed combustion chamber, an advanced digital control system with a touch panel and a programmer, as well as full support for the eBus communication bus. It is positioned as a product of the upper price category in 2021. A distinctive feature of this model is increased energy efficiency, which is achieved through the use of the condensing principle of extracting heat from natural gas combustion products. Unlike traditional gas-fired boilers, hot flue gases undergo deeper cooling, which makes it possible to extract the latent heat of water vapor condensation from them. The original proprietary engineering solution allows the Vaillant ecoTEC plus VU 20CS / 1-5 boiler to show 6-8% more efficiency than conventional design dev...ices. Passport useful power (21 kW) is enough to heat a cottage, a large multi-room city apartment, office or household premises with a total area of up to 168 m². The device is equipped with a silent circulation pump with automatic switching, an air vent valve, a three-way valve for connecting an indirect heating boiler and a modern information and analytical control system. Thanks to the closed type combustion chamber with forced smoke extraction, the boiler can be mounted directly in residential areas.
