Residential ventilation with heat recovery

Modern residential ventilation systems continuously exchange the air in the living rooms for a healthy, comfortable room climate and remove odors and pollutants. They are extremely energy-efficient: the powerful heat exchanger extracts up to 98 percent of the heat contained in the exhaust air and uses it to heat the incoming fresh air during the cold season.

Thanks to efficient DC motors, up to 15 times the thermal energy is gained per kWh of electrical energy. With a living area of ​​150 m², this means a saving of around 300 liters of heating oil per year. In summer, the heat exchanger is completely bypassed via the integrated bypass flap: the temperature-controlled circuit allows cool, filtered outside air to enter the living areas at night.

Benefit from the advantages of controlled living space ventilation with heat recovery

Controlled home ventilation with heat recovery ensures a healthy, comfortable room climate, reduces ventilation heat loss and thus saves on heating costs.

Up to 98% of the heat contained in the exhaust air can be recovered

Economical DC motors keep the air flow constant

A temperature-controlled bypass allows ventilation with cool night air in summer

The integrated outside air filter proves to be advantageous for allergy sufferers

A balanced moisture balance protects the building fabric and reduces the formation of odours

The windows can remain closed, which increases security and protects against noise and dirt

A regulated exchange of air is also important for the quality of life and work in closed rooms. However, window ventilation is random ventilation – there is either too little or too much ventilation, and energy is wasted as a result. A home ventilation system continuously exchanges the air and reduces the CO₂ concentration inside the living space to less than 0.1 percent by volume. The resident perceives this as “fresh air”. The windows can remain closed all year round. This offers increased security and brings more peace and quiet for the residents, because the street noise stays outside.

Living room ventilation with heat recovery from exhaust air

Modern residential ventilation systems are extremely energy-efficient: the powerful heat exchanger extracts up to 98 percent of the heat contained in the exhaust air and uses it to heat the incoming fresh air. In this way, no heat is lost through random ventilation during the cold months and a consistently high indoor air quality is achieved through the continuous exchange of air. The household budget is noticeably relieved by a significantly lower energy requirement. In addition, CO₂ emissions are reduced.

Central home ventilation with heat recovery in the new building

Every new building equipped with ventilation has a central device that supplies all rooms with fresh air via a duct system. The duct system is usually hidden in the floor or integrated into the wall. Only the air outlets are visible. The air exchange is automatically controlled by the ventilation control center. It is quiet in operation and protects against outside noise.
