Wolf CGB-20 + CSW-120 Set, 3-stage pump
Code: 8611400Z08Product detailed description
Wolf CGB-20 + CSW-120 wall-mounted condensing boiler with a built-in stainless steel plate heat exchanger for instantaneous domestic hot water heating.
- wall-mounted gas condensing boiler with minimal space requirements
- ideal for economical heating and efficient water heating
- state-of-the-art condensing technology delivers high savings (maximum efficiency during condensation - efficiency up to 110%), a modulating burner achieving extremely low emission levels during combustion
- option of instantaneous DHW heating via a stainless steel plate heat exchanger
- variants with modulated output from 3,2 to 50 kW
- clean, balanced design that adapts to any space
Gas wall-mounted condensing boiler Wolf CGB-20 is designed for low-temperature heating systems and domestic hot water heating, with a flow temperature up to 90 °C and a permitted operating pressure of 0,3 MPa. Modulating burner with extremely low emission values and low noise. High-performance heat exchanger made of silicon-alloyed aluminium with a unique design allowing quick and easy maintenance by 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 optionally 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 maintenance. 3-stage boiler pump to achieve maximum efficiency during condensation (standard utilisation rate up to 110 %).
