Induction Hob and extractor

BadHamster

Hi

Due to get a 60cm induction hob fitted into new kitchen. Been reading and seen that it's recommended to get a wider extractor.

Seems induction hobs due to them not creating heat, the steam tends to spread out more than the usual type of hobs.

Anyone experience of inductions ? Seems extractors come in 70cm and 90cm only really.

Thanks !

We used to have a gas hob before we got an induction hob. Can't say I noticed any difference on how the steam behaves myself.

Our extractor hood is as wide as our hob. So long as yours is at least as wide as your hob then I would think you'd be fine.

The extractor draws in the steam before it gets a chance to spread.

I read on a few places tho that because the rings themselves produce no heat the steam doesn't travel up so well. It then tends to drift out and that's why it says to use a wider extractor.

". With induction hobs, they travel sideways as well as up, so you’ll need a hood that’s wider than your hob. For example, if you have a 60cm induction hob, choose a 90cm extractor.

With gas, the steam has a candle effect that rises out then up. That means you can choose an extractor that’s the same width as your hob."

Surely steam is steam? It's hot gas that rises? Anyway, we've got a 60cm induction hob and a 60cm extractor after having a gas hob and I too haven't noticed a difference.

I believe it's the heat of the ring or gas that creates the uplift to move the steam up in an orderly fashion.

Induction creates no heat, so the steam is a bit more wayward and tends to drift sidewards. Or so it reads on the sites I seen !

I wasn't sure what it's actually like in real life, if it was much different really. Or just in some boffins head with their calculator and charts !

Heat rises so the steam is already being moved up by that force. And the extractor sucks so the steam is also encouraged by that force.

I've never really understood what people expect from extractors, it seems to be miracles. Food smells, hot food creates humidity. You minimise it but you don't eradicate it.

I think people suggesting that you need a much bigger hood are being ridiculously pedantic. Expensive, respected brands also produce extractors smaller than most hobs.

If you have room and want a big one, fill your boots but I am sure the extraction rate does far more than surface area if you're prioritising.

my extractor is the same size as my induction hob and works just as well as the old halogen hob we used to have.
it also helps keeping smell of cooking in the house down, its ducted

Sounds like marketing pseudo-science to me. If you boil water in a milk pan on an oversized gas or electric ring, it's true that there will be a rising hot air current wider than that directly above the pan, but in reality people tend to use the right size pan for the appropriate hob or moderate the flame to keep it beneath the pan because to do otherwise is a very obvious waste of energy. Steam will rise, irrespective of the method used to create it. The idea that steam generated by boiling water above gas or an electric element will "wander around sideways" is nonsense.

As others have said, it's the extraction rate of the unit that will determine its effectiveness, not relatively marginal differences in width.

In that case are you going to get one that’s deeper than your hob so you need to duck under it every time you cook?
