Energy-efficient double-circuit condensing gas boiler with closed combustion chamber and microprocessor control system. It is positioned as a product of the middle price category. It is characterized by an average level of useful power (22.4 kW), designed for organizing heating and hot water supply in private houses or cottages, large apartments, office or utility rooms up to 179 m². The Airfel Digifel Premix 25SP boiler is a highly efficient solution with a turbocharged combustion chamber, which allows it to be installed directly in residential areas. Compared to classic boilers, it has a noticeably higher efficiency, which, with the same heat output, saves 7-8% of gas. This effect is achieved through the use of proprietary complete combustion technology with a Premix burner and additiona...l cooling of combustion products, which allows you to extract the latent heat of condensation of water vapor present in hot flue gases. Both the primary and secondary heat exchangers of this model are made of high quality chromium-nickel-molybdenum stainless steel, and the design features of the secondary circuit provide the fastest possible heating of water, which is enough for two sampling points. Able to cover the household needs of a family of 2-5 people.
