Condensing gas boiler Condens GC5700iW 24/30 C 23 dual-purpose 7736902455

Modern heating comfort with Bosch Condens GC5700iW

The Bosch Condens GC5700iW 24/30 C 23 dual-function condensing gas boiler is an advanced heating solution combining high efficiency with intuitive operation and modern design. It is ideal for both new and modernized installations, providing thermal comfort and energy savings. The device is characterized by a closed combustion chamber, which guarantees safety and independence from weather conditions.

Efficiency and savings

The boiler utilizes condensation technology, which translates to high energy efficiency – up to 94% in heating mode. Smooth power modulation in the range of 1:10 allows for precise adjustment to the current heat demand, minimizing gas consumption. Additionally, the boiler is ready to operate with natural gas containing up to 20% hydrogen (H₂ Blend Ready), making it a future-proof solution. A spacious expansion vessel with a capacity of 12 liters ensures stable system operation.

Intuitive operation and remote control

Operating the boiler is extremely simple thanks to the touch control panel with a color LCD display. Intuitive buttons dedicated to the most frequently used functions make configuration and monitoring of the device easy. The ability to install a wireless communication module (Control-Key K10RF, K20RF or Connect-Key K30RF) enables remote control of the boiler via a mobile application, providing full control over the heating system from anywhere. The built-in weather compensation automatically adjusts the boiler's operation to weather conditions, optimizing energy consumption.

Construction and installation

The compact dimensions of the boiler make it easy to install in a limited space. The stainless steel aluminum-silicon heat exchanger (type C6) guarantees the durability and reliability of the device. The boiler is equipped with a filling kit compliant with EN1717 standard and an air-flue adapter Ø80/125, which facilitates installation. The booster function increases the DHW output, ensuring comfortable use of domestic hot water. An analog pressure gauge and an electronic heating water pressure sensor on the boiler display allow continuous monitoring of the system parameters.
