Outdated Product
Highly efficient double-circuit condensing gas boiler with closed combustion chamber, microprocessor control system and BusBridgeNet interface bus support. It is positioned as a product of the middle price category with a high level of useful thermal power (34.4 kW), designed to service the heating and hot water supply system in houses / cottages, large city apartments, office or utility rooms up to 275 m2. Thanks to the turbocharged combustion chamber, it can be installed directly in residential areas. Compared to boilers of traditional design, it has a noticeably higher efficiency, which, with the same heat output, provides savings from 10 to 18% of gas. Such a significant positive effect is achieved due to the additional cooling of the combustion products, which makes it possible to ext...ract the latent heat of condensation of water vapor present in hot flue gases. Both heat exchangers of the Hotpoint-Ariston Clas One 35 RDC boiler are made of high-quality chrome-nickel-molybdenum stainless steel, and the design features of the second circuit provide the fastest heating of water in an amount of up to 20 L / min, which is enough for two or three points of analysis and coverage of household needs of a family of 4-6 people.
