central ventilation with hrv
With central ventilation, all rooms in a dwelling (kitchen, living room, study, bedrooms and bathroom(s) are ventilated from a single central point.
Central ventilation is available if your home has supply air ducts or if you are prepared to invest in them.
Our solution for this:

decentral ventilation with or without heat recovery
With decentral ventilation, individual ventilation units are installed in each room. Decentral ventilation is particularly suited to use in compact new-build dwellings, in renovation projects and extensions.

Ventilation is the replacement of (polluted) indoor air with (clean) filtered outdoor air.
To keep the air quality in your home healthy, it is important to remove dirty air. Pollution of indoor air is caused by factors including:
- Cooking (harmful particulate matter)
- Air breathed out by people and animals (CO2)
- Washing or showering (damp and mould)
- Building materials and furniture (formaldehyde)
Ventilation is often thought of as opening a window. But the ventilation system is a mechanical system, which ventilates the entire house.
The options are:
- An HRV ventilation system (often called balanced ventilation or ventilation with heat recovery): a ventilation device with heat recovery (HRV) controls the exhaust of dirty air and the supply of fresh, clean air to the living room and bedrooms. Both air flows pass a heat exchanger which removes the heat from the exhaust air and transfers it to the supply air. The air is refreshed, but the heat in the air is recovered: it is retained, not lost.
- A mechanical extraction system: air from damp rooms such as the kitchen, bathroom and toilet is removed with a fan and fed outside immediately. The living room and bedrooms are ventilated with grilles above the window.
In the Netherlands, a central ventilation system unit (for the whole dwelling) is often installed in the attic. The air is drawn out of damp rooms via air ducts. In the case of an HRV system, these air ducts are also necessary to supply fresh air for the living room and bedrooms. An innovation in this field is the Multi Air Supply system, where there is no need for air supply via air ducts. A ventilation system is usually operated with a switch in the kitchen and/or bathroom. But it is also possible to control the amount of ventilation automatically by means of sensors.
HRV is a ventilation system in which the clean supply air to the dwelling and foul exhaust air from the dwelling flow through a heat exchanger. The heat exchanger extracts the heat from the exhaust air and transfers it to the supply air. This way of ventilation means that no cold from the outside air gets inside. The heat is retained, which saves a lot of energy.
