Boiler Tekla DRACO D BIO 50

The DRACO D BIO boiler is the latest model in the BIO series. Construction is based on a very efficient single-burner exchanger, in which heat exchange area has been enlarged. Self-cleaning pellet burner made of heat-resistant steel has been installed in the front door of unit. There are holes in the burner to ensure supply of air necessary for fuel combustion. Air is supplied through a blower mounted directly to air mixer. Boiler exchanger is made of high quality, attested 8 mm thick steel.
