Design of the boiler is based on high performance heat exchanger made of certified boiler steel. Ceramic plates are located over the automatic furnace and economizers in vertical flue gas ducts to increase combustion efficiency and to reduce pollutant emissions. Boilers meet the power-emission requirements of class 5 of the PN EN 303-5:2012.


*BEFA list - boilers introduced to the prestigious BEFA list should meet the highest technical and heat efficiency standards. The entry confirm the highest ecological, design and energy efficiency standards. 
Boilers from the BEFA list are co-financed in the Germany.
