Wall mounted gas condensing boiler
CGB-2

Benefit from the highest heating standards that condensing technology has to offer.

Highly efficient and advanced aptly describe the condensing technology offered by the CGB-2 from WOLF. This system makes optimum use of gas as an energy source; even the residual energy contained in the flue gas is reused through a heat recovery process. This is good for the environment, saves valuable energy and provides you with optimum heating convenience throughout the year.

The CGB-2 is ideal for detached houses and apartment blocks. It has a compact, space saving design and is mounted on the wall. The boiler is compatible with the control system from the WOLF product range and can be operated conveniently by smartphone.

WALL MOUNTED GAS CONDENSING BOILER CGB-2

Energy efficient condensing technology for the highest level of heating convenience.

The CGB-2 wall mounted gas condensing boiler provides the most advanced heating technology to supply your home efficiently with heat. The CGB-2 is ideal for detached houses and apartment blocks; for new build or modernisation projects. You can operate and monitor the boiler with the WOLF control system or directly using your smartphone. By the way, if you need large quantities of hot water for yourself and your family, simply supplement the CGB-2 with a WOLF cylinder.

• Longer boiler service life and low fuel consumption thanks to a variable modulating output from as little as 1.8 kW

• Operates very efficiently with a standard seasonal efficiency [to DIN] of 110 %, i.e. not only is optimum use made of the fuel, but the residual energy contained in the flue gas is also reused

• Protects the environment due to extremely low emissions

• Simple and intuitive to operate via the BM-2 programming unit or Smartset app

• Easy to service: a straightforward and time saving service for the contractor reduces your maintenance costs

• Quiet operation thanks to special insulation inside the casing
