x-well® central domestic ventilation

Healthy thermal comfort for every living situation. Contemporary construction or energy efficient renovation and the specifications of the EnEV require a high level of energy efficient insulation. That is why central residential ventilation systems are now standard in passive houses, low-energy houses, and housing renovations. x-well residential ventilation supplies rooms with fresh air around the clock and thus permanently creates hygienic thermal comfort and a pleasant level of humidity, not too high. By filtering dust and pollen, your own four walls also become a place of well-being for allergy sufferers. As no window needs to be opened, street noise stays outside, as do pollen and allergens. We only install external filters of the highest possible filter class ePM1 according to ISO 16890 in all central ventilation units. During air exchange, odours are naturally also removed from the kitchen, bathroom, and WC. Apart from that, x-well residential ventilation systems consume very little energy while working due to the high heat distribution. So in contrast to window airing, no heat is unnecessarily lost.

The design air vents fit in with any interior design furnishings.

Benefits of x-well central residential ventilation

  • Powerful heat recovery ensures a pleasant supply air temperature and saves heating energy
  • Effective sound insulation thanks to sophisticated system components
  • Avoids draughts
  • Automatic summer bypass for use in the cool night air in the summer
  • Demand-regulated control via humidity sensor (device dependent)
  • Low electricity consumption thanks to efficient fans
  • Device-dependent certified by Passive House Institute (PHI)
  • Device-dependent certified according by the German Institute for construction technology (DIBt)

Central residential ventilation supplies the individual rooms with fresh air via a  ventilation unit, usually placed in the plant room, and a distribution system.
