Product detailed description

WOLF CGB-20 condensing boiler with built-in plate heat exchanger made of stainless steel for flow-through heating of drinking water.

Boiler supplied with 3-stage boiler pump, combustion air supply dependent or independent of the boiler room area.

hangable gas condensing boiler with minimum space requirements
ideal for economical heating or efficient water heating
peak condensing technology ensures high savings (maximally efficient in condensing - efficiency up to 110%), modulating burner achieving extremely low combustion pollutants
the ability to flow heat DHW using a stainless steel plate heat exchanger
variants with modulating power from 3.2 to 50 kW
clean and balanced design adapts to any space

The Wolf CGB-20 gas-fired wall hung condensing boiler is designed for low-temperature heating systems and potable water heating, with a supply temperature of up to 90 °C and a permissible operating pressure of 0.3 MPa. Modulated burner with extremely low pollutant levels and low noise. High performance heat exchanger made of silicon alloy aluminium alloy with a unique design allowing easy and quick maintenance after the exchanger has been removed from the boiler under full water pressure in the system without the need to drain and fill the water and vent the system. Heat exchanger optionally with electrochemically coated surface to obtain higher corrosion resistance, better condensate drainage and self-cleaning of the exchanger surface meaning higher boiler operating efficiency as well as easier and faster cleaning of the exchanger during boiler maintenance. 3-stage boiler pump for maximum efficiency in condensing (standardized utilization rate up to 110%).
