• Scaled thermometer

OPTIMA F

• Optima S plus following additionals:
  • Turbulators inside smoke pipes
  • Electronic panel
  • Exhaust fan and scroll for vertical or horizontal flue connection
  • Fan speed modulation

Key features

• Suitable for firing of wood logs,
• Budget solution for EN 303/5 Class5 and eco-design labels, easy process of firing,
• High efficient heat exchanger design based on horizontal and vertical multi-pass structure of flue gas channels.
• New two-stage combustion technique – gasification of the fuel and subsequent pyrolysis, without any condensation
• Ceramic nozzle design with reduced flue gas emissions
• Large wood charging chamber
• Primary and secondary air regulation
• Available for pressurised circuits thanks to cooling loop connection.
• Changing the door opening direction
• Ash shaking system on grade activated by foot pedal on either side.

Advantages

• Classic combustion with low emissions and high efficiency, complying eco-design directive
• Investment saving technology
• No need for special conditions of woodlogs
• Port for cooling loop installation ensures safety for closed hydraulic circuits
• Optima S boiler can be converted to Optima F boiler in the field
