Probably another recommendation for ideas that we never get round to doing, but anyway -

As per the subject line, any recommendations for quiet rangehoods, preferably cheap. I think 60cm that just plug into a socket.

Harvey Norman has prices from 150 to 1500 at least.

Quiet rangehoods are the one that have motors installed externally on the roof or wall. They won't come cheap. Sirius or Schweigen brands are both good and offer external motors. Expect price to start around $1500.

Do whatever you want to do man.

Kind of guessed as much but am tending more towards the less than 500 range.

Yeah, Best solution is to get the motor out of of the living space, but you are unlikely to get that for a $500 budget (unless you get really lucky with some used gear.

Marketing image from Schweigen:

A $500 budget knocks out many integrated fan unites too.

One trick you could look into is to try and oversize the unit. Frankly I think this is good practice anyway.

I.e. if you have a 60cm cooktop, look for a minimum of a 90cm expel air (or 120cm rangehood for a 90cm cooktop). The extra 15cm of overhang on each side means that slight cross draft's will have a lesser impact, and the range hood can be potentially be run at a lower setting as the steam etc simply floats into the intake.

Main reason I have my loud rangehood cranking is because there allways seems to be a left to right airflow that means a bunch of the steam / smoke etc gets missed.

If the motor is integrated into the hood, then if it's quiet, that's because it's moving a small volume of air.

I guess the more air it can move the better, so presumably better look at ones that claim higher m3/hr and then run on a lower setting. Assumes they all measure it the same say I suppose.

We'd probably have to stick with 60cm as our stove is next to a wall on the left (as well as the back of course) and don't think I could cope with a 90cm unit sort of hanging off to the right.

Open plan is such a dumb idea. Don't know who makes more noise, the rangehood or the people who complain about the noise it makes while they're watching telly. Too much effort to turn the volume up apparently...

The Miele ones seem to work quite well and if you have a miele induction hob, it can switch on and adjust the fan speed automatically if you get the right one. Although any fan integrated into the unit is going to be quite loud when on full.

You wouldn't think some extra sound deadening would be that difficult...

As mentioned, external inline motor is the way to go for quietness, but they are pricey. HC90DCEXB3 from F&P RRP at $3,399 but as low as $2,279 on priceme.co.nz.

Our rangehood exits through the wall less than 300mm above the fan. I've covered what ducting there is in some loaded pvc sheet made for sound deadening. Even on full speed the noise is quite tolerable.

it depends on what you call quiet. the really good ones with external fan and silencer you can't ever hear running.

to main problems with range hoods. not big enough, most are to small. they should extend well past the cooktop. the other is restrictive piping. flexible and tight bends put extra load on it and adds noise.

don't forget filters. easy to replace and big. some use really thin filter that clogs very quickly which adds restriction which makes noise.

I had a Schweigen undermount unit installed, a 90cm rangehood over a 60cm induction cooktop. I think I went mid-level power, and so it has a 1600m3/hr rating I think. You can feel it pulling air in on the higher speeds, and in the summer evenings, I sometimes run it to pull cool air into the house strategically. I like the relatively low sound - I just did a quick test with the app on the Apple Watch for noise, and it said ambient noise in kitchen was 33dB on the cooktop, and with the rangehood on highest setting (5), it was 58dB.

It does extract a fair bit of air, and in winter if I have windows closed and a fire going, it will compete with the fireplace for air, so I always have to have a window open somewhere.

It was a bit of a cost at the time, and something which I pondered over, but I am happy with the low noise. If I could go back in time, I would probably look at having quiet bathroom extraction fans installed, though it is probably in the too hard basket now and a decent amount to pay for the short time use, but I'd likely consider it had I thought of it at the time (and the experience I have had with the kitchen rangehood).

@yann I bought couple of these below for each bathroom ventilation fans 200mm duct size and run it in medium speed. IIRC they were around $400. They are very quiet.

Thanks very much for that - looks interesting, though in my ensuite bathroom there isn't much roof space (mono-pitch), so I do wonder how this might be accessed - I think there would be a way, but probably not straightforward. It would work in the main bathroom, though that doesn't get used much at all. I'll definitely bookmark it, and have a ponder and see whether there are add on costs to get it wrangled in (likely with professional help). It would be nice having a quiet bathroom fan though.

Cheers!

Something like this maybe ?

I have a Bosch 86cm integrated one and on the lowest setting it's genuinely barely audible. Obviously it's not moving enormous amounts of air but it's enough 90% of the time - I only need to use the higher settings if I'm cooking meat at high heat.

Such an improvement from my old F&P, which was probably as loud on its lowest setting as the Bosch is on its highest. I'm happy as I really wanted the Schweigen but couldn't fit it into the budget.
