BOSCH Condens GC2300iW 15/25C — condensing gas boiler with instantaneous domestic hot water production

BOSCH Condens GC2300iW 15/25C is a compact wall-mounted condensing gas boiler designed for central heating and instantaneous domestic hot water production. It is suitable for apartments, private houses and renovation projects where an efficient heating solution is required without a separate hot water cylinder.

The boiler is equipped with a UI300 control unit with a 2” LCD display, built-in A-class circulation pump, 6-litre expansion vessel and integrated weather-compensated control function. The aluminium-silicon heat exchanger ensures efficient heat transfer, while the 1:10 modulation range helps adapt the boiler output to the actual heat demand and reduce gas consumption.

The unit supports Control-Key and Connect-Key modules for extended connectivity and remote control. It can also be converted for operation with liquefied gas using the appropriate conversion kit.
