About solution
The Bosch Condens 2500 W WBC 28-1 DCE gas condensing boiler (24-28 kW) with an energy-efficient frequency pump is designed specifically for low energy consumption. It has a minimal impact on the environment, ensuring comfort and coziness in the room.
- Gas wall-mounted condensing boiler for heating and hot water supply
- Hot water is produced in a plate heat exchanger by a flow-through method
- A closed combustion chamber boiler with forced flue gas extraction can be installed indoors regardless of the presence of a chimney
- Infinitely variable automatic power control in heating and hot water mode
- LCD with operating parameters and standardized error codes facilitates set-up and maintenance
- Control of operation via room controllers and function modules via Heatronic 3 bus
Technical equipment
- Stainless steel burner with pre-mixing
- Ionization electrode for flame control
- Draft control device with automatic boiler shutdown
- Temperature limiter that protects the heat exchanger from overheating
- Built-in heating pump with energy-saving mode
- Infinitely variable modulated fan with speed control sensor
- Exhaust of combustion products and supply of combustion air through coaxial flues Ø60/100 or Ø80/125
- Possibility of connection to the underfloor heating system
- Heatronic 3 control panel with display of operating modes and standard error codes for setup and operation
