Bosch GC7700i W 24/28C is a modern gas condensing combi boiler from the Bosch Condens 7700i W series. It is designed for both space heating and instant domestic hot water production without the need for a separate external hot water cylinder.
The boiler has a nominal heating output of 24 kW and an A energy efficiency class for heating and water heating. Thanks to condensing technology, Bosch GC7700i W 24/28C uses heat from flue gases more efficiently, helping to reduce gas consumption compared with older non-condensing gas boilers.
This model is suitable for apartments, private houses and townhouses where a compact wall-mounted solution for heating and hot water is required. Unlike the 15P and 24P versions, the 24/28C is a combi model and prepares domestic hot water in instant flow mode.
We provide sales, installation, replacement, connection, setup and maintenance of Bosch gas boilers in Tallinn and Harjumaa. We can also help select the right model, replace an old gas boiler and prepare the system for safe operation.
