Every day we produce moisture, CO₂, and particulate matter in our homes. Without sufficient fresh air, it accumulates, with possible consequences such as mold, allergies, or headaches. Ventilating is literally letting your home's lungs breathe.
But how do you do that smartly? Opening windows helps, but a well-thought-out ventilation system continuously ensures a healthy indoor climate without you having to think about it. Especially in well-insulated homes, it is important to balance air quality and energy efficiency.
In the construction world, we speak of four basic systems, each with a different combination of natural or mechanical supply and exhaust. Below, I explain them clearly so you know what to look for.
The price strongly depends on the chosen system, the size of your home, and ease of installation. A simple system C with self-regulating grilles and a central box starts around 2,500 to 4,000 euros (incl. installation). System D with heat recovery is more expensive: count on 7,000 to 12,000 euros or more, depending on the ductwork. For a precise estimate, request our free valuation.
Extra costs may arise in an existing home if breaking work is needed for the ducts. Fortunately, there are now also decentralized system D solutions, where you install small units per room, limiting the intervention.
Installing a ventilation system in an existing home often requires creativity. System C is popular because it can be done with simple adjustments: replace old grilles, install an extraction box, and pull ducts through existing shafts. System D requires more work, but with decentralized balanced ventilation, it becomes easier. In Flanders, it is mandatory during major renovations to comply with the ventilation standard.
Also a mechanical ventilation system in an old house is possible, provided you take into account noise standards and airtightness. Get good advice beforehand.
In cold months, we don't want to throw away heat. System D with heat recovery then scores best: you retain up to 90% of the heat. With system C, self-regulating grilles ensure that no more air enters than necessary. Don't forget to properly maintain your device and replace filters annually.
The Flemish government encourages energy-efficient ventilation. For system D with heat recovery, you can apply for a grant via Fluvius (up to a few hundred euros). Also, new-build homes must meet the EPB requirements, which prescribe a minimum ventilation flow rate. Always check the current regulations, which may differ by construction year and municipality.
