I use Fujioh. Very satisfied with its performance. My ducting is more than 10' (beyond recommended) but the suction is still good. Normally just use the lowest speed 1. No smell inside house. Easy to clean and maintain. My hobs are modular type so I use model FUJIOH MF 1100V. I would recommend in your case FUJIOH GFP 900V/R (90cm)

This is not something new. I think this perhaps copy the Japanese Fujioh brand that has been around for probably 10 years

Recirculating is not something desirable, at least for me. Need to clean and replace filter and usually still cannot remove odor I think.

For your 7m, probably the hood location is not at 7m. How many bend. My hood also do not recommend long run but I'm glad I never follow. Mine is about 20' with 1 bend at the hood there

wah

5m probably to right or left and then 2m up(?). Can't imagine going where. Roof? You plan for ventilating with which hood brand?

If you plan to put in-line booster fan, just make sure the hood you use can get rid of the oil vapor before entering the via duct. Otherwise, the fan will accumulate oil in long run. That airegard is not designed for that, I believe. It is for pure air circulation.

Maybe you can just try without it first. It might just work without additional boost since air is not much of a load anyway. The performance drop might be not that significant. Which Fotile model you were looking at?

I think Zan81 was talking about the an in-duct fan booster, not the normal exhaust fan put on the wall

Ducted hood no need filter since the smelly air is exhausted externally. The filter in the hood is for removing oil vapor from deposited inside the duct. If you really want a good hood, go for Fujioh. I use similar model like MF-1100. Almost no smell in kitchen and none go to living hall. No greasy surface in kitchen at all. Easy to maintain. Expensive, maybe but no regret at all. Bought it 10 years ago I think

I think many model out there and they cover wide price range. If you state your budget, maybe you get more suitable feedback

Rinnai

Not really cheap for this unknown brand

For gas hob, Rinnai is very good for me though I never use one You can ask any retail shop

Anyway, how bad it can be? If they are good for 3 years, then it would be 1388/36 = 38.56/month

I think it can last at least 3 years since, the hood is just motor and the hob ... I dunno. nothing much there right? Sure it can last

I guess just take the measurement of your old hob. Everything. Hole size is very important but if cannot fit, it can be widened which is more troublesome.

That feww cm gap is just fine. Normally double sided tape is used to fix hob at its location. It is not just pit like that. NO need to be wide tape, but just 0.5 to 1 cm is just fine. My hob comes with tape,

I use Fujioh and never regret but it was long time ago already. New one even great with oil smasher.

The main purpose is to prevent rain water from entering. If cannot use the round one that flat one will do just fine. Mine quite similar to that flat. No problem.

It will not. Once fume is suck into hood, it goes through hood. The only way to disturb is to blow fan directly to your hobs Ventilation or ceiling fan is far and not strong enough to disturb flow of air from hobs to hood.

Installing hood with windows nearby? Then why need hob if can just use vent fan through the windows

The reason for hood is to vent out cooking odor and oil/water vapor out of the kitchen. If you put your hood near the windows, the hood will not only suck air from the hobs but also from outside of the windows thus lowering the suction effectiveness.

I would put my hobs/hood away from windows. The best is to have one way air flow direction. Another reason to avoid hobs near windows is that I'd rather clean my flat splash wall than cleaning windows. It is much easier

Mine came with the hood. I bought short aluminum flexible hose and then connect to a long PVC pipe (about 15') to the wall and put the cap out there

It is not about how good it is and very popular there. The most important thing is if anything wrong with it, can you easily get it serviced. How long the brand will survive here

Easier to clean or not is a matter of design regardless which type you choose.

I think no matter what type of stove, the height rule probably the same. It is all about how the air flows inside the kitchen. Too far the cooking vapor get carried away before being suck into chimney. The windows too close, the hood is sucking external air but not the cooking vapor.

Noise is related to suction power which is depends on fan type and size. As you can see, the smaller fan makes more noise and bigger one

My hob is both induction and ceramic. I use modular type. So each one is independent. If anything wrong with power supply, I still have other hobs to use I have been using the slant type hood. Most of the time I use speed 1 (very quiet) and have good suction. The kitchen cabinet is clean and never felt oily due to oil vapor. Well, my hood vents out air, not circulating anyway. Been using this for almost 20 years and extremely satisfied with it.
