High-tech German condensing double-circuit gas boiler for wall mounting with a closed combustion chamber (forced smoke extraction), a built-in boiler with a volume of 46 liters and an advanced digital control system with a Wi-Fi module. It is the middle model in the line of similar devices of the 2021 model year. It is positioned as a premium product aimed at demanding users who choose reliable branded European climate technology. It can be an excellent choice for organizing a new or upgrading an existing heating and hot water supply system for a cottage or a spacious apartment with a total area of up to 200 m². Installation of the Viessmann Vitodens 111-W Z023144 25kW boiler is possible directly in residential premises. The condensing principle of operation of the boiler makes it possible...to extract the latent heat of condensation of the water vapor of the combustion products, which increases the overall efficiency up to 109% (compared to conventional boilers). The built-in high-quality stainless steel boiler minimizes the number of start-stop cycles for hot water preparation.
