Gas condensing boilers
CGB-2 family
The CGB-2 series of WOLF gas condensing boilers covers the entire spectrum of gas condensing technology: from straightforward gas heating systems to combi boilers and models with integrated DHW storage cylinders.
Versatile and flexible
CGB-2
The WOLF CGB-2 gas condensing boiler is the basic model. This gas heater covers heating output ratings of 14, 20 or 24 kW with the models CGB-2/14, CGB-2/20 and CGB-2/24.

CGS-2L
The CGB-2L model is a freestanding unit with an integrated floorstanding stratification cylinder. The CGB-2-14/120L offers 14 kW of heating output and 120 litres storage capacity.
The CGB-2-20/160L has a storage capacity of 160 litres and generates 20 kW heating output. The CGB-2-24/200L has an output of 24 kW and a capacity of 200 litres.

CGS-2R
The CGB-2R gas condensing boiler is the best solution if your water is particularly hard. This is because the indirect coil heat exchanger in the integrated cylinder protects the system against scaling.
The models CGB-2-14/150R, CGB-2-20/150R and CGB-2-24/150R have an output of 14, 20 or 24 kW and all have a storage capacity of 150 litres.

CGW-2L
The wall-mounted version of the CGW-2L is also equipped with a wall-mounted cylinder. The models CGB-2-14/100L, CGW-2-20/120L and CGW-2-24/140L have a heating output of 14, 20 or 24 kW and storage capacities of 100, 120 or 140 litres.

CSZ-2R
The CSZ-2R gas condensing solar centre is designed for combination with solar thermal collectors. The models CGZ-2-14/300R, CGZ-2-20/300R and CGZ-2-24/300R have a heating output of 14, 20 or 24 kW. The solar cylinders of all three models hold 300 litres.
Basic information
Dimensions (WxHxD) 1850mm x 600mm x 1013mm
CGB-2-38/55
The CGB-2-38/55 gas condensing boiler is suitable for older buildings or apartment blocks thanks to its ample output of 38 or 55 kW. The boiler is the most robust in its performance class.
It was developed for especially long runtimes and particularly for DHW heating in multi-unit buildings, which can put any boiler to the test.
