Condensing gas boiler dual-function ILEA 18/25 214271

Condensing boiler for efficient heating and hot water

This dual-function ILEA 18/25 condensing gas boiler is a solution for homes and apartments where both central heating and domestic hot water are needed. The compact dimensions of the device allow for installation even in limited spaces, and its efficiency translates into lower operating costs. The boiler is primarily distinguished by its stainless steel construction, which guarantees durability and corrosion resistance.

Construction and key features

The ILEA 18/25 boiler has been designed with ease of use and maintenance in mind. All key components are easily accessible from the front of the device, making maintenance and repairs easier. The built-in plate heat exchanger ensures rapid production of domestic hot water, and the modulating gas burner automatically adjusts the power to the current demand, resulting in energy savings. The integrated backflow flap prevents flue gas backflow, and the expansion vessel ensures stable pressure in the installation.

• High efficiency: Thanks to condensing technology, the boiler achieves high combustion efficiency, minimizing energy losses and reducing heating costs.
• Stainless steel: The stainless steel body provides corrosion resistance and long device life.
• Plate heat exchanger: Fast production of domestic hot water thanks to the efficient plate heat exchanger.
• Modulating burner: Automatic power adjustment to demand – gas savings and thermal comfort.
• Easy maintenance: Access to all elements from the front of the boiler facilitates maintenance and repairs.
• Built-in safety features: CH safety valve, CH water pressure sensor, CH diaphragm vessel and bypass protecting against overheating ensure safe operation of the device.
• Wide modulation range: Precise power adjustment to current heating needs and low CO2 and NOx emissions (NOx class: 6).

Technical parameters and application

The ILEA 18/25 boiler is characterized by a nominal power in the range of 4-23 kW (depending on operating conditions), which makes it suitable for both smaller houses and larger apartments. The ability to connect to a chimney with a diameter of 60/100 mm and standard gas connections (3/4 inch) facilitate installation in existing installations. The device is adapted to work with natural gas, but it is possible to convert it to propane GZ 35 and GZ 41.5 – giving flexibility in the choice of fuel source. The minimum return temperature is 20°C, which allows it to work with most modern heating systems. The capacity of the expansion vessel is 7 liters, ensuring stabilization of the pressure in the central heating installation.
