Condensing boiler dual-purpose CIAO X 25C 20187761

Condensing boiler – efficient heating and domestic hot water

The CIAO X 25C boiler is a modern heating solution combining high energy efficiency and user comfort. The device is designed for both heating rooms and preparing domestic hot water. Thanks to the use of advanced condensation technology, the boiler achieves high efficiency, which translates into lower operating costs and a reduced environmental impact.

Construction and operating parameters

Compact dimensions (400 x 700 x 275 mm) facilitate installation in various spaces. The boiler runs on natural gas or with the addition of hydrogen (up to 20%), making it a future-proof solution in line with the EU's sustainable development goals. It is equipped with a high-efficiency stainless steel heat exchanger and an energy-saving circulating pump (EEI ≤ 0.20). A wide modulation range (1:8) allows for precise adjustment of power to current heating needs. This ensures not only thermal comfort but also optimization of fuel consumption.

Advantages for the installer and user

• High efficiency: Energy class CO and DHW at level A guarantees low heating and hot water preparation costs. The boiler efficiency is 93%.
• Power modulation: Thanks to the power modulation from 3.1 kW to 20 kW, the boiler perfectly adapts to the heat demand, which translates into savings and comfort.
• Built-in functions: The built-in weather controller and the ability to control two or three heating circuits (with additional CONNECT modules) facilitate the installation and configuration of the heating system.
• Safety: The boiler has a built-in safety group, overpressure valve and filling/draining valve, ensuring safe operation of the device.
• Quiet operation: Optimized design minimizes noise levels during boiler operation.
• Compatibility: Control via smart Hi and Comfort programmers increases user comfort.
• Low NOx emissions: Class 6 (EN 15502) guarantees minimal impact on the natural environment.
• Hot water flow rate: The hot water flow rate is 14.3 l/min, ensuring comfortable use even with simultaneous consumption in several points.
• Range Rated: Range rated certificate allows adjusting the boiler power to the actual installation requirements – flexibility for the installer!

The CIAO X 25C boiler is an investment in comfort, savings and ecology. Its advanced functions and high efficiency make it an ideal solution for both new and modernized heating installations.
