The fireplace stove B² uses an innovative heating technology to reach extremely clean heating values. It drops below the minimum values that are required from 2015 onwards up to 88% and the CO-value up to 96%, at the same time reaching an efficiency factor of 81%. The B² is manufactured in Germany according to highest standards of quality. It offers the reliability, lifetime and security that you can expect from a modern fireplace. By completely recirculating the combustion chamber a large part of the developing radiant heat is converted into convection heat. This is a major advantage as this warm air spreads equally through the whole room and not only heats the place where the stove is located.
