The MYNUTE GREEN 25 C.S.I. model includes a built-in non-return valve for collective flue systems, facilitating easy installation.

Technical Features
The boilers feature a condensing heat exchanger made from a single aluminum pipe, enhancing thermal conductivity and corrosion resistance. The premix burner reduces NOx emissions, achieving Class 5 ecological performance. The S.A.R.A. system optimizes temperature control for energy efficiency.

Control and Functionality
The user-friendly control panel includes a white backlight digital display. Features include a "Survivor" function for operation during probe failure and a pre-heating function for reduced domestic hot water waiting time.

Installation and Compatibility
The boilers are compatible with remote control panels and hydraulic separators. The MYNUTE GREEN 25 C.S.I. model is designed for quick installation in collective flue systems, reducing costs.

Performance and Efficiency
Efficiency ratings reach up to 108.9% at partial load, with low power consumption and IPX5D electrical protection. The boilers are designed for a maximum pressure of 3 bar and temperatures up to 90°C.

Environmental Considerations
With low NOx emissions and high efficiency, the Mynute Green series supports environmental sustainability and complies with current regulations.

Additional Features
