CLAS B

Wall-hung boiler with 40 lt integrated storage

Wall-hung boiler with 40 lt integrated storage CLAS B | Ariston
Wall-hung boiler with 40 lt integrated storage. All the water that you need in a very compact solution.
 
  • Thanks to the accurate design of the combustion unit, Clas B has a very high efficiency, up to 93,8% (24 FF) in the category of traditional boilers;
  • More energy saving is guaranteed by the two-speed pump, in comparison with a traditional pump;
  • The “AUTO function” in addition with the modulating thermoregulation accessories avoid temperature fluctuations, and by consequence the reduced consumption is assured;
  • Clas B permits a very easy and comfortable use, thanks to the LCD Digit Display, and an easy monitoring of boiler’s functioning through error codes;  
  • Thanks to the BUS interface included, the boiler can is  designed for the multi-zone thermoregulation management,  and the solar system management;
  • With the addition of Clima Manger, it’s possible to have a full remote control of the boiler and a modulating thermoregulation;COMFORT
  • The compatibility with modulating thermoregulation accessories, and the «AUTO function» avoid temperature fluctuations and peaks, forgiving a constant temperature for the maximum thermic comfort;
  • The «Comfort Function» gives instantaneous hot water, for 30’, after first withdrawal, eliminating wasting times;  
  • A very big amount of domestic hot water, up to 25,2 l/min,  is provided thanks to the built-in 40 lt storage;
  • The increased expansion vessel makes the boiler suitable for large areas heating;
  • Clas B is made up with the best material available: the copper used for the primary heat exchanger, and the stainless steel used for the sanitary exchanger, guarantee high reliability and very long lifecycle;
  • The modulating fan forgives a very accurate air flow in order to allow a good combustion;
  • The use of anti-seizing systems prevent freezing and scale accumulation,  protecting not only the wall-hung boiler, but even your whole system;
  • The external combustion analysis port permits easy check of combustion quality;
  • AUTO
