Solution for extractor fan on cooking island (downdraft vs ceiling)

Hello everyone,

now as a newcomer I have to come up with a problem that is giving me a headache.

We want to integrate the cooktop in a kind of kitchen island (red in the picture). So far I have planned with a Bora (or similar) in recirculation mode.
Now I am wavering again (partly because the Bora is apparently only allowed to be installed by professionals, etc.).
How can I find topics and posts about extractor hoods, e.g. from Bora or similar?

Alternatively, I am now considering a ceiling extractor fan. Here a vented version would probably be better. That is certainly better in terms of comfort. On the other hand, it pains me to cut a hole in the wall right away in the new house. Energetically it is of course also not optimal, but you save yourself filter changes and you get the humidity out of the room.

I don’t like those hanging recirculation solutions. Nor those that are basically built in a classic way and then connected to the ceiling with a "tower".
So I quickly ended up with a fully integrated ceiling extractor. For this you would have to build some kind of box. It could extend from the wall to the end of the cooktop and also include lighting.
Some questions about this:

- Has anyone built something like this?
- If I do it myself, I thought of a wooden construction made of OSB boards or similar. Can it be plastered? Alternatively, I could use cover sides from Ikea. But then it doesn’t look so good at the corners because you have open gaps.
- If I don’t trust myself to do it at the end - who would do such a thing (carpenter, joiner, kitchen fitter???). My sister’s brother is a trained joiner. I still have to talk to him. Maybe he can help with construction...

Regards, Marco

PS: Since the countertop is about 83 cm high and the ceiling has a height of 2.46 m, the extractor would be at about 2.10 m. So about 127 cm above the stove. Does that work well? Since the expensive Bora is off the table, I would also buy a good & expensive hood (which manufacturers are good? Miele costs about €1800, for example – a good 80cm stove again about €1500. So similar in price)

Have you ever looked at berbel.de and gutmann-exklusiv.de?

No - but now

Berbel offers exactly the things I don't want.

In addition to range hoods, Gutmann also has ceiling hoods in their program. Basically, they look like all the others. Are they good?
Gutmann also offers a kind of retractable hood. Something like that would also be easy to install. However, I don't think recirculation at the ceiling is that good. I would then prefer a downdraft extractor again. (and that thing costs over €4000)
The ceiling hoods (e.g., Claro) would still be doable at €1500.

Berbel writes:
Like extractor hoods, ceiling fans above the cooking area (usually kitchen islands) are mounted directly under the ceiling and are designed to integrate as inconspicuously as possible into the room with their flat design. However, it should be noted that fats and oils produced during frying cannot rise to the required height of 1.50 m above the cooktop (2.4 m ceiling and 90 cm working height). The reason is that these molecules cool down again on the long way up and literally fall down. With these conventional ceiling fans, design clearly takes precedence over function. With the berbel ceiling lift hoods, you have the optimal distance for perfect fat capture, and when the hood is not needed, it retracts under the ceiling and frees the view.

I fear the Berbel extractor hoods are also beyond my budget Much more than €3000 in total should not be spent (possibly a bit more for it being an exhaust system. You save that again over the next few years).

So I probably have to consider: ceiling hood - with more grease on the countertop/stove, or some cooktop with an integrated downdraft extractor (the new Miele also looks very good).

It is often advised to move the cooktop away from the island. There are really many good reasons for this, not just the simpler fan solution. I would simply plan the cooktop on the left side and save myself all the money and tinkering. Especially if you have induction, you really spend much less time directly at the cooktop than you might think.

Just a note about extractor hoods with exhaust/recirculation. With exhaust, you don’t have to change the carbon filter, but the grease filters should still be cleaned regularly so they don't become resinous.
