Boiler Tekla DRACO Duo Bio 15
A steel double-furnace boiler with a burner for pellets. The design of DRACO DUO BIO boiler is based on proven and very effective double-furnace exchanger. In BIO series boilers, there is a unique burner for pellets installed instead of a retort burner, which is made of heat-resistant steel. There are two holes on the grate of the burner, which provide the flow of air necessary for the combustion, supplied by a blower installed directly to the air mixer. The boiler exchanger is made of high quality attested steel 8 mm thick. A proper operation of the boiler is controlled by a modern electronic adjuster with clear LCD display.
The advantages of the boiler:
- Boiler exchanger made of high quality steel 8 mm thick
- Additional (emergency) combustion chamber with a water grate
- Completely automatic operation of the boiler (automatic ignition and extinguishing of a burner)
- Easy and fast operation and maintenance
- Return temperature adjustment mode through adjuster control on a four-way valve
- Room thermostat option
- Economical operation
- Low level of harmful substances in exhaust fumes
- High efficiency
