Hello,
we want to build our kitchen with a relatively open design. We currently have a similar setup in a rented house with a fairly efficient ducted extractor fan (600 m³/h (353 cfm) rated capacity, about 0.5 m (1.6 ft) aluminum flexible duct DN150 to the wall vent) and are satisfied with its performance.
What we are not happy with is the requirement to always have a window open.
In the new build, the kitchen is not located on an exterior wall, so the ductwork for the extractor will need to be several meters longer. One option would be about 4-5 m (13-16 ft) of duct running through the roof, which would likely require at least two 90° elbows. Alternatively, a 90° elbow could be used to run the duct horizontally through the utility room towards the north, again about 4-5 m (13-16 ft) of duct. Both options would allow the fan unit to be installed outside of the kitchen, which would help reduce noise levels.
We still need to consider fresh air supply. Would it be possible to run fresh air intake under the floor slab and have an external intake chimney similar to those used for centralized mechanical ventilation systems? This would require a motorized damper to ensure airtightness when the system is not in operation.
Or is all this effort not justified, and should we just opt for a recirculation system instead?

In my opinion, there are three important and very good range hood manufacturers: Falmec, Berbel, and of course Gutmann.

However, a hood from the three mentioned brands doesn’t always have to be very expensive.
It always depends on which model you choose, and that is something you can control yourself.
What’s the point of buying a hood, for example, from BSH if you can get a visually similar model with better craftsmanship for less or only slightly more?
This only works when combined with a kitchen purchase and from the right dealer.

You just have to consider what is important to you.
For example, an oven with 40 automatic programs, or rather a very good extractor hood that ensures clean air.
We often sell extractor hoods in that price range, and the kitchens then cost not 30,000-50,000 € but around 13,000 €.
