First up... I don't have a problem with cooker hoods at all, so what would I be gaining and what problems would I be introducing?
I want a specific hob and it takes virtually no depth, so my oven and washing machine both fit under parts of the hob, and a cupboard to the left is all usable for pots. No matter how I did it, a ducted system is going to compromise part of that as there's more going on under the counter.
My hob will also be against an external wall... I don't have the problem of needing to route the air somewhere nor of hanging a hood in the middle of the room, etc. If I had an island, ducted induction makes a lot more sense.
But then... I'm all about the functional and am trying to build a high-spec but extremely simple kitchen... no magic, all of the function on display and everything working pretty much as you see it. I like that heat rises, and hot vapours from cooking would rise directly into a visible hood and out through the external wall. I like that most of the work here is done by the heat of the food itself, merely catching the rising steam / vapours is very light work for a hood and beautiful in it's function.
When I look at a ducted induction system, well they go against nature... to pull steam and vapours to the side and down they need to pull a high volume of air in at a relatively high speed. To then ensure it's quiet they need to increase the fans and size of the holes they pull this through.
Hence this:
But this has side effects... nothing significant, but it's certainly not for free. For the magic of "no hood!" this large visible hole exists, or a popup exists... and it's pull-based... which means it's effectively also blowing over the food. The more effective it is, the more that effect of blowing / sucking air over the food exists.
What happens when you blow over a hot soup? or a hot drink? It cools. Evaporative cooling in effect.
It feels then like we're doing a hell of a lot for very little:
Under counter space compromised
Trying to be magic, but has to work really hard for it
Not needed for my space as my hob is on an external brick wall and I am re-using an existing vent hole
The entire magic effect has a very small impact on the cooking itself by cooling food
For me, it goes against the spirit of the kitchen I'm building. I prefer the non-magical, function that is visible.
I should say what my problem is with Bora, etc.
