BOSCH Condens GC2300iW 24/25C condensing gas boiler, 7736901534
BOSCH Condens GC2300iW 24/25C — condensing gas boiler with instantaneous domestic hot water production
BOSCH Condens GC2300iW 24/25C is a compact wall-mounted condensing gas boiler designed for central heating and instantaneous domestic hot water production. This model is suitable for apartments, private houses and renovation projects where an efficient heating solution with integrated hot water production is required without a separate hot water cylinder.
The boiler features a 1:10 modulation range, UI300 control unit with a 2” LCD display, built-in A-class circulation pump, 6-litre expansion vessel and integrated weather-compensated control. The aluminium-silicon alloy heat exchanger provides efficient heat transfer, while Control-Key and Connect-Key module support allows additional control and connectivity options.
The boiler can be converted for liquefied gas operation using the appropriate conversion kit.
