Condensing gas boiler Condens GC5700iW 15 P 23 single-function 7736902456

Next-generation condensing gas boiler

The Condens GC5700iW 15 P 23 condensing gas boiler is an advanced heating solution combining high energy efficiency, reliability, and ease of use. Designed for both new and modernized installations, it is perfect for single-family homes and commercial buildings. Thanks to the use of innovative technologies, the boiler provides thermal comfort while reducing operating costs.

Performance and economy

The boiler utilizes the principle of flue gas condensation, which allows for the recovery of additional energy and achieving high efficiency – up to 94%. Smooth power modulation in the range of 1:9 allows the device to adapt to the current heat demand, which translates into savings. The built-in expansion vessel with a capacity of 12 liters minimizes the risk of pressure problems in the installation. Additionally, the boiler is adapted to operate with a hydrogen mixture (up to 20% H₂), making it an investment for the future.

User comfort and control

Operating the boiler is extremely intuitive thanks to the touch control panel with a color LCD display. It allows for easy navigation through the menu and adjustment of the device's operating parameters. The boiler has a built-in weather compensation system that optimizes the heating system's operation depending on the weather conditions. The possibility of installing a wireless communication module (available separately) allows for remote control of the boiler using a smartphone or tablet via the Bosch HomeCom Easy or EasyControl CT200 applications.

Construction and durability

The heat exchanger made of stainless aluminum-silicon (type C6) guarantees long-lasting and trouble-free operation of the device. The air-flue adapter with a diameter of Ø80/125 mm provides flexibility during installation. The boiler has been designed with easy installation and servicing in mind, and its compact dimensions make it easy to find a suitable place in the boiler room. An analog pressure gauge and an electronic heating water pressure sensor on the display provide constant control over the system's operation.
