Housing ventilation with heat recovery for efficiency & comfort

Part of your quality of life and at work in confined spaces depends on a controlled air exchange rate. However, airing by opening windows is random ventilation – it results in either too much or too little ventilation and therefore wastes energy. A mechanical ventilation system exchanges the air continuously and reduces the CO₂ concentration within the living space to less than 0.1 percent by volume. Occupants perceive this as "fresh air". This means windows can stay closed all year round. This provides higher security and greater quiet for occupants since street noise stays outside.

Mechanical ventilation with heat recovery from extract air

Modern mechanical ventilation systems are extremely energy efficient: A powerful heat exchanger recovers up to 98 percent of the latent heat in the extract air and uses it to heat incoming fresh air. Consequently, no heat is lost through accidental ventilation in the colder months, and the continuous air exchanges ensure a consistently high level of indoor air quality. The household budget is noticeably eased by a significantly lower energy demand. CO₂ emissions are also reduced.

Central mechanical ventilation with heat recovery in new build

Every new build equipped with mechanical ventilation has a central unit that supplies all rooms with fresh air via a duct system. In most cases, the duct system is concealed in the floor or integrated into the walls. Air diffusers are all that remain visible. The air exchange rate is regulated automatically by the central ventilation unit. It is quiet in operation and protects against external noise.

Mechanical ventilation with heat recovery

Advanced mechanical ventilation systems continuously change the air in the living space for a healthy, comfortable indoor environment along with removing odours and noxious substances. And they do so in an extremely energy efficient way: A powerful heat exchanger recovers up to 98 percent of the latent heat in the extract air and uses it to heat the incoming fresh air during the colder months.

Thanks to efficient DC motors, for each kWh of electrical energy, up to 15 times more heating energy is recovered. A living space of 150 m² can generate savings of around 300 litres of fuel oil per year. In summer, the heat exchanger is completely bypassed via the integral bypass damper: The temperature controlled circuit allows cool, filtered outdoor air to enter the living space at night.
