Wolf CGB-K-20, 3-stupňové čerpadlo, TÚV
Code: 8611402Z10Product detailed description
WOLF CGB-20 condensing boiler with built-in plate heat exchanger made of stainless steel for flow-through heating of drinking water.
- a suspended gas condensing boiler with minimal space requirements
- ideal for economical heating or efficient water heating
- peak condensing technology ensures high savings (maximally efficient in condensing - up to 110% efficiency), modulating burner achieving extremely low pollutant combustion values
- flow-through DHW heating capability using a stainless steel plate heat exchanger
- varieties 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%).
