Wall mounted gas condensing boiler

The quality solution for particularly high heating standards. Suitable for apartments and smaller apartment blocks.

The FGB wall mounted gas condensing boiler operates with the most advanced condensing technology, which employs heat recovery to make highly efficient use of gas as a fuel. This is good for the environment, saves valuable energy and provides optimum heating convenience. The appliance is compatible with the WOLF control system and, using the ISM7e interface module, you can also operate your heating system at any time with your smartphone or PC via the Smartset portal.

This highly compact and space saving appliance is mounted on the wall, for example in the kitchen or in a fitted cupboard, and is also ideal for modernisation. The FGB-K combi version is characterised by exceptionally high DHW convenience. No more cold water surprises – thanks to very short heat-up times and consistent hot water temperatures.
