A Breath of Fresh Air
The Advantages of Heat Recovery Ventilation
We spend more than 80% of our time indoors. The quality of our indoor environment affects how we feel. Good air not only creates a sense of cosiness but also keeps us healthy and productive. This is what we call living comfort, ideally achieved through 40 to 50 per cent humidity, fresh and clean air, and a temperature that feels comfortable.
Versatile Solutions
With our versatile solutions, you get over 25 years of ventilation experience, delivering living comfort and well-being. No more regularly opening windows wide and wasting valuable energy. Our ventilation systems use extract air ducts to channel stale air, unpleasant odours, and water vapour to the outside, while supplying fresh, filtered air and new oxygen to your rooms. The system regulates airflow rates and brings fresh air through the ducts to every corner of the room, ensuring you and all members of your household can literally breathe easier.

Clean Air and Balanced Humidity
The filters in our ventilation systems keep out dust particles and pests. They reduce pollen concentration by up to 95%, and can be easily replaced with no tools required. Your home should be kept evenly warm and maintain balanced humidity. That’s why our heat exchangers remove up to 90% of the heat from the extract air and transfer it to the fresh air. They also recover up to 60% of the humidity and supply it to the fresh indoor air.
Quiet and Unobtrusive
Our ventilation systems operate extremely quietly and remain unobtrusive in your home. A qualified contractor will install a STIEBEL ELTRON central ventilation unit in a ceiling or wall. The sound-optimised ducts supply rooms with fresh air. Decentralised systems can also be retrofitted easily, making them ideal for modernisation projects. Our innovative solutions and green technologies give you breathing space and greater home comfort.
Ventilation in the Home and Workplace
Ensuring a constant supply of fresh air is crucial for maintaining good health and well-being. Ventilation systems are an excellent way to achieve this by providing clean air while saving energy. Explore our range of ventilation systems.
