- wall-mounted gas condensing boiler with minimal space requirements
- ideal for economical heating and efficient water heating
- top-class condensing technology ensures high savings (maximally efficient during condensation - efficiency up to 110%), a modulating burner achieving extremely low levels of combustion pollutants
- the option of instantaneous DHW heating via a stainless steel plate heat exchanger
- variants with a modulated output from 3.2 to 50 kW
- a clean, balanced design that adapts to any space
Wolf CGB-24 wall-mounted gas condensing boiler is designed for low-temperature heating systems and drinking water heating, with a flow temperature of up to 90 °C and a permitted operating pressure of 0.3 MPa. Modulating burner with extremely low pollutant levels and low noise. A high-performance heat exchanger made of a silicon-aluminium alloy with a unique design allowing quick and easy maintenance after tilting the exchanger out of the boiler under full water pressure in the system, without the need to drain and refill water or vent the system. The heat exchanger is also available with an electrochemically coated surface for higher corrosion resistance, better condensate drainage and self-cleaning of the exchanger surface, resulting in higher operating efficiency of the boiler as well as easier and faster cleaning of the exchanger during boiler maintenance. 3-stage boiler pump to achieve maximum efficiency during condensation (standard utilisation rate of up to 110%).
