Bi-fuel boiler with woody biomass wood or pellets with inverted flame

Useful power adaptable from 9.5 kW to 31.2 kW

• Aspirated burner for pellets
• Eccentric combustion with triple modulation inverted flame
  - inverter modulation on boiler temperature: to maintain the correct stoichiometric ratio
  - flue gas temperature modulation: to prolong autonomy while guaranteeing combustion safety
  - modulation on optical reading: to adjust the speed of the fuel loading auger, optimizing combustion
• Very high efficiency >90% and low emissions
• Incandescent combustion chamber in special 8 mm thick carbon steel, highly thermostable and resistant to both high temperatures and potential chemical attacks
• AISI 310 stainless steel thermal steel grate of 15 mm
• 10 side primary air channel injectors with a thickness of 4 mm
• Vertical pipes with blade turbulators activated by rods and rockers with timed programming to increase the efficiency and therefore the efficiency of the generator (practical extraction of the ashes from the front)
• Pellet burner behind the boiler, in AISI 304 stainless steel, self-cleaning
• Modulating fan with inverter control placed on intake for combustion optimization
• Double safety loading auger
• Safety exchanger
• Pellet tank: optional, which can be positioned on the left and right side, which automatically feeds the burner
• Large loading compartment equipped with functional automatic by-pass for logs of wood, to guarantee long loading intervals
• BIOTRONIC control panel for managing:
  - automatic fuel switching
  - operating states
  - safety devices (audible and visual alarms)
  - values ​​detected by elements of the system
  - solar thermal circuit
• Armored photosensor for flame presence and intensity control
• Ultra-fast ignition (at 3 minutes)
• Power management in "sanitary accumulation" which allows the combination with sanitary producers
• Minimum charge level sensor (pellets)
• 4-star environmental certification
• Conto Termico 2.0 incentive (reduced emissions - high efficiency) for the replacement of some types of existing heating systems

Optional:
- Anti-condensation kit
- Pellet tanks
- Buffer tanks - Puffer for technical water and DHW production: PUFFER PSS, MULTIPOWER, MULTIPOWER PLUS
