The short answer is: Effective is likely not affordable, or integrable into a residential architecture unless planned from inception.

No, it's far too far away. Decide which you want: an unobstructed view (move your stove) or a stove on an island (get an island range hood). I chose to keep my stove at the island, and I LOVE cooking there. It's wonderful not facing the wall and seeing (and sensing) the space around me. I now never want my stove against a wall again - cooking at a kitchen island is wonderful. But, to get that, I am willing to have a proper island range hood. I didn't put my range in the island for an unobstructed view, I did it for space and light.

Not a pro, but I vote for a wall cooktop. Currently my (downdraft) cooktop is on the island and I hate it. It takes up the lion’s share of prep space that I want to use and it’s constantly in the way. Yes sure I can cook facing my guests (or really, my hungry children) but the actual time I’m standing there actively cooking is much less than all the chopping/prep. Since it also appears the hood venting is ineffective from the other comments I’d strongly suggest looking at a wall location.

The Best Cattura is a pop up exhaust. It goes with induction best.

" time I’m standing there actively cooking is much less than all the chopping/prep."

I keep reading about how much prep time people do, which is true.....but why dose that mean you can't do both on the island? I do. Most of my chopping, etc is done beside my stove on the island. I do very little stuff on the counter that is against the wall.......most of it is related to plugged in small appliances (since I stupidly didn't get an accessible outlet on my island).

I like to point out that time involved completely depends on what you're cooking. 100% can be spent at the range. For salads it's 0%. Cooking often allows more conversation with others in your space. And is more likely to involve guests.

"Cooking often allows more conversation with others in your space. And is more likely to involve guests."

I disagree. I've never had anyone share space with me while I am actually cooking. Whether I am flipping hamburgers, stirring a pot of meatballs in sauce, steaming vegetables, stir frying, making an omelette, or whatever, I've never had anyone--family or guest--in "my space" at the cooktop while that is happening. How would you do those things with people hovering next to you? Prepping on the other hand, definitely. I've had friends and family chop with me, toss and plate salads, shuck corn on the cob, scoop cookies onto baking sheets, nibble on cheese, drink wine, etc. all at the island, without a cooktop. It also enables children to watch and help me prep, mix cake batter, wait in anticipation of licking the bowl, and all the other joyful activities you can have with children at a kitchen island without a cooktop on it.

This thread is about a cooktop on the island and the island is the space. My fault for leaving that vague. So your space can mean your kitchen. It can mean that if you have a setup where guests can hang out while you flip their burgers. And in that space you can talk.

I agree that young children are more likely to want to participate in prep duties you won't schedule when guests are over.

Of course your personality will play a role.

So choose accordingly based on your needs.

Oh, please! There's nothing about having a cooktop on an island would make those things impossible or even unwise. You write as if putting a cooktop on the island will suck all the sociability and joy of a kitchen up the range hood! One person chops while the other person mans the wok, or one person prepares the salad while the other person stirs the pasta sauce? Totally do-able and totally safe, even on the same "space" of the island.

You sound like you're making up a fable or parable to warn people of the (imaginary) negative effects of cooking on an island.

I CAN cook and prep on the island, but I don’t like to! As you can see from my super detailed drawing, I have a little prep space next to the cooktop. That’s where I put my cutting board, bowls, tools. But I often end up needing to use the actual cooktop as prep space, even as I’m cooking which is...not ideal. I have lots of space on the other end of the island, but that means I have to move further from my sink (across from cooktop to the right) and fridge (across from cooktop to the bottom). So that means I stay put and make do in the less than ideal space.

This seems to have moved away from the OP's question.

To the the original question... "I am considering ceiling mount for vent hood. Does it work effectively?"

It will work

It won't be as effective as a hood at the proper distance above the cooktop.

You will need a higher CFM blower than if you used a standard height hood. probalby at least double the CFM.

Do what makes you happy and works for you.

Enjoy your new kitchen and cooking with familiy and friends.

TV - I seem to remember other posts where you overreacted in a highly emotional state, and wrote how everyone is just wanting to contradict you. I remember your kitchen is beautiful. It sounds like the OP doesn't want to install an island hood. View my post as just an anonymous person on the internet with opinions different from yours. Relax.

Yes, emotional in that I hate to see people being so emotionally flowery on the internet. Yup, I'll just assume you're an anonymous and hystrionic person. Got it.

"Yup, an anonymous and hystrionic person. Got it."

Sigh.
