not to bad. notice how its wider than the hob and it also comes out to the edge of the bench, while the cooking area is pushed back toward the wall.

 

 

 

 

this is poor. the vent is at the back, the cabinets (which form the hood) don't come to the front of the hob and while there is a lip on the bottom front of the cabinet there is none on the sides.

very good pic which shows it well. the cabinets do not stick out far enough. add to that many people install the hobs to the front as much as possible. so its ever further away from the cabinets. even worse, they push back the hood vents to the wall (notice how thin the bosh unit is). that means the actual suction part is even further away. and it gets worse as many don't put the strips under the cabinets so the whole length of the cabinet is the hood, ie the airflow comes from the two sides where there is no hob. so it sucks in air, but not the stuff coming out of the pots etc.

 

this is a very common "award winning kitchen" fail. tho even worse is the downdraft type, or even worse still the recirc type (which should be banned).

 

also remember that the vapors etc coming from the hob do not go straight up, they go up and out at an angle. so you really want the range hood to be wider and further out than the hob. eg use a 800mm hood on a 600mm hob. is its sized correctly you do not need high flow (and noisy fans) to achieve good a result.

 

 

Coverage width-wise we shouldn't have an issue as we're going for a 900mm rangehood over a 600mm hob. I'll have a talk to the kitchen company when we're finalising plans about placement in terms of where it sits back-to-front (ie, depth); my sense is they like narrow ones and place them as far back as they can so they can provide some usable cupboard space in front of the rangehood, but we can look to sacrifice some of this cupboard space to allow it to be situated further forward.

 

Sorry, I'm a little lost with this bit:

 

and it gets worse as many don't put the strips under the cabinets so the whole length of the cabinet is the hood, ie the airflow comes from the two sides where there is no hob. so it sucks in air, but not the stuff coming out of the pots etc.

 

... and would like to ensure I do understand in case it does highlight something we need to tweak or discuss with the kitchen company. By 'strips' do you mean something like vertical panels that essentially demarcate the 'sides' of the rangehood from the tops of the cupboards either side, sort of in the places I've marked here? Is this an actual thing that's done, or are you saying it's what should be done?

correct. yes it needs to be done and it does get done, but sadly rarely.

 

sadly the fancier the kitchen the less good things get done. sometimes you get it by default in cheap kitchen cabinets because its the ends of the cabinets. i have seen it in good high end kitchens where they have made the effort to put it in.  

 

you can do it by making the side cabinets come down, ie the centre one with the range hood in it is shorter (but same length front). but the ones i have seen done have fitted strips and matched the looks.

I've had some experience with this as my mother can't stand loud rangehoods.
I'm pretty much the same but don't have the money to play with to sort it 🤣

https://www.awardappliances.co.nz/product/cho82-90si-90cm-low-noise-canopy-hood

My parents have installed the above style in two separate homes now, so just throwing it out there that there are options that are quieter (whilst still performing for the most part) but as others have said they're not as cheap.

https://www.noelleeming.co.nz/p/award-70cm-low-noise-canopy-rangehoof/N228920.html might be one I should get for my smaller space come to think of it 🤔
Look for the "Low Noise" tag specifically.

 


Also a big hi to @timmmay and @jonathan18 too, a few long time users I haven't crossed paths with in several years.

 

 

And hi back to you! 

 

Yeah, I can imagine I'm going to be a bit annoyed if it's fairly loud, but the co-owner is happy with the F&P model so that's probably it! Not sure if there are conventional built-in units that are quieter, or whether we'd have had to go with one with an external motor - this Schweigen would have been fine cost-wise, but I'm not sure of how much of a hassle it would be installing it, given the ducting limitations we have. Which is why we can't go with a canopy model - there's only that space above the top of the cupboards to get the ducting to exit the outside wall; I guess at least it'll be a relatively direct and short route of only about 2m.

sorry, i was looking for a pic of one with the strips and came across this gem. a perfect showcase of a bad range hood install but it looks "good".

 

notice how far back the top cabinets are, then how far back the filters are. add in thats is completely flush wit hthe cabinets which is the 'hood'. so only the rear burners are covered and a lot of the air flow is going to come in sideways, from the front and sides. it will even suck air down from the ceiling. so your going to waste a lot of airflow blowing clean air out.

 

something like this would require a big noisy motor to do the job properly. if you make the hood capture properly then you need very little airflow, making little noise.

Wouldn’t it depend on how much air was moving? It's similar to our local fish & chip shop.

 

The old Classique rangehood had an angled filter at the back but the front panel did tilt forward to cover the stove top while operating. On an outside wall you could have a duct as short as 150mm.

if you look at commercial kitchens the hood is huge in volume and it comes right up the front and down a lot, so they capture well (sucking air vertically). there is a lot of room for the air to curve to the fan. plus they move a lot of air. 

 

so pretty much the opposite of what many residential hoods are like.

 

its not just about airflow, but direction the airflow comes from. unless you have something to guide it and block off the air you don't want to suck in. you need to have the shape to give it the direction, otherwise you suck in clean air and leave the dirty air in the kitchen.

FWIW, I recently replaced the extractor hood over our gas/electric stove/oven ... the old Robinhood model was always getting oily (even resorted to inserting paper towels sandwiched between mesh screens), and then conked out.

 

Replaced with Bellini slimline and it's great .... more powerful motors, twin intakes with charcoal filters, and noise not too intrusive.  About $150 from Bunnings.

We have been very happy with Falmec.

 

Noise and efficiency was at front of mind. Bit pricey compared to other options but you get what you pay for.

 

If you're planning on enjoying it for more than a few years and low noise and power is important to you, defo check it out. It's powerful enough to not need to be directly over the elements.

 

Actually, it's so good we've sometimes forgotten its on.

 

Installation is important. If you're in Auckland Rangehood Solutions were very good.

I got a Vogue (rebranded Midea) from Trade Depot on special back in March. They list the noise level for all the range hoods they sell. Works great. Still noisy but no noisier than much more expensive units. Most of their units also have extensions for high ceilings (which I have)

I installed this one for a friend and was pleasantly surprised by its noise level
31db at 1 setting. 48 at highest from memory try and get this or lower at highest setting. Good suction too.
Have a listen in the shop. Noel leeming does this one I believe

timmmay: For $3K plus it had better be pretty awesome!

We have a speciality cleaning firm coming to have a look and quote on Friday. Even if it's expensive it would be a lot less hassle than pulling the old rangehood out and putting a new one in, given it will be a different size and require changes.

 

 

 

how’d you get on?
Uncanny that on Friday morning I saw a van with  signwritting and one of the services listed was “Rangehood cleans”!

The cleaning company didn't turn up. I will call them next week to arrange another time.

The only cleaning guy I found who would even consider doing the job didn't turn up either of the times he said he would. I think cleaning a residential rangehood isn't practical.

 

CrazyM:

 

I did a DIY job on my F&P. The hood and filters were fine but the motor dripped as well as being loud and gutless.

 

Removed the motor and ran new semi-rigid duct up to an inline centrifugal fan in the roof space. I thought about wiring the fan into the existing rangehood button but instead got it with a wireless remote. Adjustable 3 speeds and works perfectly. Much quieter (mostly airflow noise) and MUCH more powerful

@CrazyM sorry I missed your post the first time around. Interesting idea... replacing the motor sounds much less work than having the whole assembly ripped out and replaced.

 

Some questions  🙂

 

 

 

  • How difficult was it to get the fan into the ceiling and get it all connected up?
  • Once the old motor was out of the rangehood do you just have a dangling pipe inside the rangehood?
  • Does that extractor / controller work together out of the box or would something else need to be done to connect them?
  • What size did you get an how well does it work?
  • Did it cost much other than motor and controller?

I looked at semi rigid ducting and it seems very expensive - $60 per meter and I'd need about 6 - 8 meters so it'd cost more than the rangehood.
