Bosch GC7700i W 15P is a modern wall-mounted gas condensing boiler from the Bosch Condens 7700i W series. It is designed for efficient space heating and is suitable for private houses, apartments, townhouses and heating system modernization projects.
The Bosch GC7700i W 15P has a nominal heating output of 15 kW and a seasonal space heating efficiency of 94%. Thanks to condensing technology, the boiler uses heat from flue gases more efficiently, helping to reduce gas consumption compared with older non-condensing gas boilers.
This model is not a combi boiler with instant domestic hot water production. For hot water preparation, Bosch GC7700i W 15P can be connected to an external hot water cylinder. This makes it a good choice for homes where a separate cylinder is already installed or where a larger hot water volume is required.
We provide sales, installation, replacement, connection, setup and maintenance of Bosch gas boilers in Tallinn and Harjumaa. We can also help select a suitable external hot water cylinder, replace an old gas boiler and prepare the system for safe operation.
