Wall mounted gas condensing boiler
CGB-2K

Benefit from the highest heating standards with integral DHW heating.

The CGB-2K wall mounted gas condensing combi boiler operates with the most advanced condensing technology which makes highly efficient use of the fuel. Even the residual energy contained in the flue gas is reused here as part of the heat recovery process. This is good for the environment, saves valuable energy and provides optimum heating convenience. At the same time, the CGB-2K supplies you with fresh hot water, quickly and reliably –at any time of day.

The boiler is compatible with the control system from the WOLF product range and can be operated conveniently with your smartphone. The space saving CGB-2K is a wall mounted boiler and is ideal for renovation projects or installation in a new building.
