Energy-efficient double-circuit condensing gas boiler with closed combustion chamber, digital control system, continuous electronic modulation of the burner and OpenTherm bus support for integrated smart home systems. It is one of the most affordable models of double-circuit condensing boilers of a similar class with a useful power of ~ 20 kW. Designed for vertical wall mounting, it can be used for organizing heating in private houses and cottages, spacious apartments, office and utility rooms up to 146 m². It is a modern energy-efficient solution with a turbocharged combustion chamber, which allows the installation of the BAXI Duo-tec Compact 20 boiler directly in residential areas. Compared to classic double-circuit boilers, it has a significantly higher efficiency, which, with an equal...heat output, saves 3-5% of gas. This effect is achieved through an additional stage of cooling the combustion products, which makes it possible to extract the latent heat of condensation of water vapor present in the flue gases. The reliable boiler heat exchanger is made of AISI 316L chromium-nickel-molybdenum steel, resistant to acidified condensate. Due to the support of two temperature ranges of the coolant, such a boiler can be used in underfloor heating systems.
