Italtherm CITY CLASS 25 KR 20 kW

Efficient boiler for radiator heating and underfloor heating

With an installed power of 20 kW, the Italtherm CITY CLASS 25 KR condensing boiler is ideal for heating apartments or private houses up to 160 m². It is equipped with an Intelligent Combustion System, which is smart electronics capable of monitoring many equipment operating parameters and adapting to any changes in real time. This allows the boiler to respond to fluctuations in the water temperature in the system and adjust to maintain it at the required level. The same ICS system controls the gas valve and water pump, ensuring the optimal air/gas ratio in the burner according to the water flow in the system. This ensures economical use of fuel, and in maximum power mode the boiler does not consume more than 2.64 m³/h of gas. In addition, the boiler offers a wide range of temperature settings, allowing the user to set the heating water from 20 °C (suitable for underfloor heating systems) to 80 °C (for radiators).

Technological solutions for boiler reliability and durability

The internal structure of the boiler, that is, its components and components, deserves special attention. Inside the Italtherm CITY CLASS 25 KR boiler you will find a high-quality circulation pump from Grundfos, a brass hydraulic group, as well as a burner and heat exchanger made of stainless steel, which is ideal for boilers of this type due to its resistance to corrosion caused by condensation. The manufacturer especially emphasizes the increased cross-section of the heat exchanger tubes, which promotes more efficient heat transfer and prevents the formation of plaque and blockages. The combination of these technological solutions guarantees high reliability of all components and simplifies maintenance, even in areas with hard water. This Italtherm CITY CLASS 25 KR boiler is an excellent choice for both new buildings and old houses with worn-out water supply pipes.
