An Effective Solution for Private Houses on Gas

The Bosch Condens GC5300i WM 24/100S double-circuit gas boiler is an ideal choice for heating and hot water supply in private houses with an area of about 190 m², where a family of 3-4 people lives. Thanks to its closed (turbocharged) combustion chamber, it does not require an exhaust flue, allowing greater flexibility in the choice of installation location (although please note that due to its weight of 115 kg, it is intended for floor installation only).

Advanced Tuning for Comfort and Savings

This boiler operates on the condensation principle, which ensures high efficiency and economical gas consumption. The modulating burner further contributes to savings by automatically adjusting the heating output in the range from 10% to 100%, depending on the current heat needs. The wide modulation range of the burner allows you to precisely adjust the water temperature in heating systems (from 30°C to 82°C) and hot water supply (from 40°C to 60°C). The boiler has high productivity (up to 22.9 l/min) and a “hot start” function, providing instant access to hot water when the tap is opened. The built-in storage boiler with a volume of 100 liters provides a reliable supply of hot water.

Smart Boiler with Remote Control Possibility

It is interesting to note that the Bosch Condens GC5300i WM 24/100S boiler can be integrated into smart home systems and automated using additional devices and thermostats (this may require additional investment). It also supports control via a mobile application (with the Bosch EasyControl CT 200 controller) and a web browser (with the MB LAN2 communication module). These features can significantly reduce heating and hot water costs while providing maximum comfort and control.
