Device
The Bosch 6000 18 kW gas boiler is built using the most advanced contemporary technological advancements. The primary heat exchanger, which heats the heating agent, is the main component of the design.
The gas burner, when used in conjunction with a heat exchanger to achieve optimal efficiency, is the second most crucial part. The coolant is supplied to the heat exchanger by the circulation pump, where it reaches its maximum temperature.
After that, the liquid enters the secondary heat exchanger, where it transfers a portion of the thermal energy to the water flow used in the domestic hot water system. After that, the OV is discharged into the heating circuit after passing through a three-way valve, partially mixing with the return flow, and reaching the temperature that the settings have set.
Draft from a fan is used to remove smoke. A self-diagnosis sensor system and a control board manage the functioning of every component.

For which rooms is it best suited??
