Bring new freshness into your four walls.

Due to stricter building regulations, e.g. the energy saving ordinance (EnEV), new-builds are becoming more or less hermetically sealed buildings without natural air exchange to the outside. However, everyday activities, such as cooking, washing, or showering, as well as the air breathed by the residents, increase the humidity in the rooms. Without sufficient ventilation, the health risks to people and to the building arising from mould forming are increased. To ensure the minimum hygienic air exchange, it would be necessary to air throughout for approx. 10 minutes every two hours. How can this be achieved in reality?

This is where controlled domestic ventilation solves the problem. Domestic ventilation ensures you have fresh air and great thermal comfort. The Kermi x-well domestic ventilation systems are available as central or decentralised systems – for renovations in existing buildings as well as for new-builds.

x-well^® domestic ventilation – the decentralised system

• Both for retrospective fitting when modernising and renovating as well as for new-builds.
• Decentralised domestic ventilation with heat recovery .
• Optically attractive, glazed air vents (x-well D12).
• Lowest sound emissions.
• Easiest maintenance.

Ideal for renovation.

Controlled domestic ventilation installed retrospectively or planned right from the start. Kermi x-well particularly makes retrospective installation easy. During renovation, all the devices are positioned in the walls using simple core hole drilling. In a new-build, they can be installed directly into a special installation brick.

Flexible system for every application.

Single family house or multi-storey building, new-build or renovation. That means: little effort combined with low costs right from planning to installation.

Ventilation with heat recovery.

The integrated heat exchanger heats up during the fan's exhaust air phase and after reversing the fan's direction, transfers the saved energy to the fresh air flowing in. That way, an efficient heat recovery is achieved.

Beautifully finished inside and out.

With its elegant design, the outer cover fits perfectly into the look of the house. The glass surface of the design inner cover (x-well D12) with its attractive and high quality appearance is appealing and ensures optimal, low noise flow of the air.
