Vaillant ecoTEC pure VUW 246/7-2 18.5 kW (0010023030)

Highly efficient double-circuit condensing gas boiler of small capacity with a closed combustion chamber and full support for the popular eBus communication bus. The most important distinguishing feature of this model is increased energy efficiency, which is achieved due to the condensing principle of extracting heat from natural gas combustion products. Unlike traditional gas boilers, hot flue gases undergo deeper cooling, which makes it possible to extract and use the latent heat of water vapor condensation.

This progressive design allows the Vaillant ecoTEC pure VUW 246/7-2 boiler to show 5-6% more energy efficiency than classic double-circuit boilers. Passport net power (18.4 kW) is enough to heat a small private house / cottage, multi-room city apartment, commercial or communal household premises with a total area of up to 148 m2. In addition, the boiler can quickly heat water in an amount up to 11.5 L / min (when heated at 30 °C). This is enough for the stable operation of one or two points of analysis and to meet the typical household needs of a family consisting of 3-5 people. Thanks to the closed combustion chamber, quiet circulation pump and forced flue gas removal, the boiler can be placed directly in residential areas.
