Biodom 21

The reliability of the Biodom 21 boiler is the result of many years of investments into the development of biomass heating systems and practical experiences in their installation and maintenance. Biodom 21 is a system of complete combustion of wood biomass, including an automatic ignition, regulation and pellet feed.

Biodom 21 is a smaller version of the Biodom 27 boiler, adapted for the market of energy-efficient houses, where there is no need for high heating output. Thanks to its thermal energy storage, the Biodom 21 boiler can heat even classic houses of up to 300 m2 or buildings that in the past spent as much as 4000 l of fuel oil. This boiler also uses the tried-and-tested BioLogic technology, which allows the boiler to adjust to changing operating conditions, thereby ensuring optimal efficiency and stable operation with minimal maintenance costs throughout the years of operation. BioLogic technology thus prevents improper boiler operation due to varying pellet quality, changed air density conditions (air pressure, air temperature), or flue flow (cold or hot flue). Quality construction, modern exterior design, exceptional customisation, and reliable operation are just a few of the features that provide comfort, safety, and savings.
