Discover which system suits your home and budget. Our local experts provide clear advice, from type A to D.
The best ventilation system depends on your house type, insulation level and budget. For new builds and thoroughly renovated homes, a balanced system D with heat recovery is usually the most energy-efficient and comfortable choice. For existing homes with natural supply openings, system C can be a practical and affordable upgrade.
<p>Every ventilation system has its own strengths. System C mechanically extracts moist air and lets fresh air in through grilles. System D mechanically controls both supply and extract and recovers heat. Demand control and quiet operation make modern D systems popular, but correct installation is crucial. Our local specialists assess your situation and advise without sales pressure.</p>
In Flanders, houses are better insulated than ever. That saves energy, but it also means that moisture, odours and polluted air no longer disappear naturally. For your health and to prevent mould and dust mites, a good ventilation system is not a luxury but a necessity. The EPB (Energy Performance and Indoor Climate) standard therefore prescribes minimum ventilation for new builds and major renovations.
There are four basic principles, depending on how fresh air enters and stale air is extracted. We list them for you.
In Flanders, the choice is usually between C and D. System C is cheaper to buy and easier to install in existing constructions. You do sacrifice some comfort: supply through grilles can cause draughts and you recover no heat. System D with heat recovery is more expensive, but pays for itself through lower energy bills. Moreover, it filters the incoming air, ideal for hay fever sufferers or homes along a busy road. Modern D systems operate whisper-quiet and adjust automatically via CO2 or humidity sensors.
The price depends strongly on the type, the size of the house and the chosen brand. For an average terraced house, you can expect:
Installation by a certified installer often costs another €1,000 - €2,500. Request multiple quotes to compare. Compare prices and grants here.
The Flemish government encourages energy-efficient ventilation. Through the Mijn VerbouwPremie you may qualify for a grant if you have a system D with heat recovery installed. This can be particularly interesting when renovating older homes. The grant is income-dependent and only applies for work by a contractor. View the grant conditions for your situation.
A ventilation system works optimally if you clean it regularly and replace the filters. For system D, you should replace or rinse the filters every 3 to 6 months on average. For system C, it is best to clean the extract openings annually. Also have the ducts inspected every few years by a specialist. A well-maintained system lasts longer and remains quiet and efficient.
