eK! is a wall-mounted condensing boiler with a sealed combustion chamber, a stainless steel heat exchanger, and instantaneous production of domestic hot water. It stands out for its compact size, with a depth of just 25 cm, making it ideal for both replacements and new installations, even in existing boiler boxes. The standard regulation system with Gas Adaptive technology allows for self-calibration of combustion, facilitating
Initial start-up and maintenance operations. The eK! C 24 has a heating/DHW output of 24 kW, domestic hot water production of up to 13.1 l/min, and runs on methane or LPG (supplied kit).

HIGH PERFORMANCE BURNER
Made of conductive ceramic fiber. The ceramic properties of the fibers, together with an innovative combustion process, make it highly conductive, self-supporting, resistant and highly porous with the following advantages:
- Long-lasting thanks to the resistance of the fibres to high temperatures (over 1000°C)
- Maximum silence due to the structure and porosity of the fibre
- High thermal insulation which allows for reduced heat transmission to the lower layers of the burner at high surface temperatures, increasing the life of the gaskets
- Flame stability, high degree of modulation and reduced polluting emissions thanks to the precision of the air-gas ratio self-regulation system.
