Bosch GS4000 is a wall-mounted chimney gas boiler from the Bosch Gaz Star 4000 W series. It is designed for space heating and instant domestic hot water production through an integrated heat exchanger.
The Bosch GS4000 has a heating output range of 10.9–24 kW and is suitable for apartments, private houses, townhouses and properties with a traditional chimney flue. It is a combi gas boiler, so no external hot water cylinder is required for domestic hot water.
Bosch Gaz Star GS4000W 24 C is an open combustion chamber gas boiler with natural draught. For this reason, the chimney, draught, ventilation, combustion air supply and safety requirements must be checked before installation. This type of boiler must not be installed without verifying proper flue gas evacuation and air supply conditions.
Bosch GS4000 is suitable for replacing an older chimney gas boiler if the existing chimney and ventilation meet the requirements. The boiler is equipped with the Bosch Heatronic 3 control system, integrated A-class pump and expansion vessel. Its compact wall-mounted design makes it suitable for properties with limited space.
We provide installation, replacement, connection, setup and maintenance of Bosch GS4000 gas boilers in Tallinn and Harjumaa. Before installation, we check the gas connection, chimney flue, ventilation, air supply, draught and safe operating conditions.
