Ferroli KALIS 34 C natural gas boiler

The Ferroli KALIS 34 C natural gas boiler, reference 695W00344, is a condensing boiler that offers a heating and domestic hot water (DHW) solution with maximum efficiency and exceptional performance. Designed to provide thermal comfort in the home, this boiler is characterized by its 30 kW heating power and 34 kW in DHW, making it an ideal option for medium to large homes with multiple hot water usage points.

The heart of the KALIS 34 C is its high-performance stainless steel primary heat exchanger, which ensures greater durability and resistance to corrosion, prolonging the boiler's lifespan. This heat exchanger is designed to maximize combustion efficiency, allowing the boiler to achieve a maximum efficiency of 109.4%, meaning it makes the most of the heat generated during combustion, reducing gas consumption and, consequently, energy costs.

Thanks to its 1:6 modulation range, this boiler can adapt to small heating demands, which is especially useful in transitional periods or when only a minimal amount of heat is needed. This wide modulation range ensures that the boiler operates efficiently even with low heat demands, optimizing its performance and reducing gas consumption.

The intelligent "Gas Adaptive" system (MC2: Multi Combustion Control) is one of the most advanced features of the KALIS 34 C. This system automatically adjusts and optimizes combustion according to variations in gas and air inlet conditions, ensuring cleaner, more efficient, and safer combustion. Additionally, this system makes the boiler compatible with both natural gas and LPG, without the need for additional conversion kits, providing greater installation flexibility.
