Bosch Condens GC2300i W 15 P is a wall-mounted gas condensing boiler from the Bosch Condens 2300i W series. It is suitable for apartments, private houses, townhouses and properties where a compact, economical and reliable gas boiler is required.
The Bosch GC2300i W 15 P has a heating output of up to 15 kW at 80/60 °C and up to 16.1 kW in low-temperature 50/30 °C operation. 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.
The 15 P version is not an instant combi boiler. For domestic hot water production, Bosch Condens GC2300i W 15 P is connected to an external hot water cylinder. This solution is suitable for properties where a separate hot water volume and stable heating system operation are required.
Bosch Condens GC2300i W 15 P is suitable for replacing older gas boilers, modernizing heating systems and creating an energy-efficient gas heating solution. Before installation, the gas connection, flue system, ventilation, condensate drain, heating system and safety requirements must be checked.
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.
