• Latest-generation CERAMAT ceramic fiber burner with an exceptionally wide modulation range, allowing for combustion optimization and gas savings
• Additional boiler soundproofing system based on modern sound-absorbing materials
• Very quiet boiler operation - just 37 dB (for 24 and 28 kW boilers)
• Highly efficient circulation pump
• Modulating electronically controlled fan
• Highest NOx class (Class 6)
• Complete safety system
• Compatible with multi-zone modules for heating systems
