Bosch GC9700iW 40 H — powerful heating for modern gas systems
Bosch GC9700iW 40 H is a wall-mounted condensing gas boiler designed for space heating and modern heating systems. This model is suitable for private houses, larger apartments and buildings where a higher heat output is required.
The Bosch GC9700iW 40 H uses condensing technology. This allows the boiler to use heat from flue gases more efficiently and helps reduce gas consumption compared with a standard non-condensing gas boiler. In a properly designed heating system, a condensing gas boiler can provide efficient and stable heating during the cold season.
Bosch GC9700iW 40 H is suitable for use with radiators, underfloor heating, hydraulic modules and an indirect hot water cylinder. The H version is mainly intended for heating, while domestic hot water is usually prepared through a separate cylinder.
Because Bosch GC9700iW 40 H is a high-output gas boiler, the installation conditions must be checked before purchase and installation. This includes the gas pipework, flue system, ventilation, air supply, heating connections and service access around the appliance.
