The Chaffoteaux Mira Advance Link D2 35kW features a single loop stainless steel primary exchanger with cross sections increased by 142% over the previous version. This allows for greater heat efficiency and long life. Seasonal efficiency of 94% and class A+ ensure low consumption and significant savings on utility bills.
With a 1:10 modulation ratio, this boiler provides optimal comfort by adapting to different thermal needs. Electronic combustion control through E-burning System D2 optimizes boiler operation, improving air quality and reducing harmful gas emissions. In addition, the SRA function improves energy efficiency, increasing comfort in the home.
The Mira Advance Link D2 is designed for easy and versatile installation. It can be installed in partially protected locations and supports a variety of flue gas discharge options, including kits for compatibility with positive pressure (C10) collective flues. In addition, it is compatible with 20% H2 hydrogen blends, further reducing environmental impact.
The boiler offers low pollutant emissions, thanks to its NOx class 6, which ensures low emissions of nitrogen oxides, contributing to a cleaner environment. In addition, the boiler is compatible with natural gas, LPG and propane air without the use of additional kits, making it a versatile choice for a variety of homes.
