Kalis 24C Ferroli gas condensing boiler

Ferroli Kalis 24 C condensing gas boiler, wall installation, compact size, with 24.3 kW of power, Energy classification A, NOx emission class 6, silent, Adaptive gas system and easy maintenance, Backlit digital display.

This gas boiler is very quiet, it is prepared for operation with 50 mm diameter smoke outlets, its seasonal efficiency of 93% is one of the highest in its category, it is a boiler that is easy to install and carry out any type of operation. maintenance.

CHARACTERISTICS

• Modulation range 1/6: It can start with demands 6 times smaller than its rated power. Essential for small heating demands in between-season periods.
• MC2: Multi Combustion Control: “Gas Adaptive” Intelligent “Gas Adaptive” system that automatically monitors and optimizes combustion even when the gas and air inlet conditions vary
• High-performance stainless steel monothermal primary exchanger.
• Minimum polluting emissions (class 6 according to EN 15502-1) already in accordance with the provisions of the ErP directive of 09/26/2018 (NOx emissions < 56mg/kWh).
• Maximum silence and acoustic comfort, almost impossible to distinguish the sound of the boiler during operation (mod. 24).
• Device specifically designed to facilitate installation and maintenance
• High seasonal heating efficiency among the highest in its category: 93%
• Device that can be combined with preheating systems for domestic hot water using solar panels
• Smoke Protection System, through an external accessory with a non-return valve that allows the boiler to be installed directly in overpressure collective systems
• MGR: Methane LPG Ready, through a simple configuration the boiler is capable of working with both Natural Gas and LPG without the need to use additional conversion kits.
• 50 mm diameter smoke outlets: Prepared for operation with 50 mm diameter smoke outlets
• Operation in a partially protected place with a minimum temperature of -5ºC.
