The joy of induction hobs
Posted by: Richard in Gadgets, House, Personal, Review, TechnologyI’m a big fan of anything that is shiny, or has buttons. Regular readers will know this. If not, well, can you guess what phone I have? It’s not a difficult question….
So when Frances was designing our kitchen, I was delighted to discover that my love of shinybuttony things could be brought to bear on such an important part of our new house.
My Kitchen Gadgets post from last year has merited a few e-mail exchanges with readers about how good (or not) Induction hobs are, and I’ve been meaning to collate them all into a dedicated post.
Needless to say, I’m still extremely pleased with ours. It always features in a ‘tour of the house’ when we have friends staying for the first time. This isn’t as bad as it sounds. Mostly friends are interested in what we’ve done, and like the kitchen…. So don’t worry
The only real negative is you need special pans, and the ones I’d spent ages choosing 3 or 4 years ago weren’t suitable (we just had a ‘normal’ electric hob). That said, I have found some nice pans with a good thick base which work just fine. They’re not a rare commodity either: Just be sure to keep it in mind when you wander around a department store choosing new pans.
I’d challenge anybody who thinks that “gas is best” to give induction a try. I find that the time to get water to the boil with our hob and pans is surprisingly fast. Much faster, I think, than gas ever was in my experience. Plus it returns to the boil in no time, after, say, you add rice to a boiling pan of water. Oh, and it’s a whole lot more energy efficient.
We purchased AEG 4 ring induction hob model. I think they do a few models, but I was quite insistent we get all induction rings, rather than 50/50 (which Frances was favouring, not least that it was cheaper), but I didn’t want one style for some rings, and another for the others. Would confuse me endlessly, and mess up my timings if I needed to switch around. They may do a five hob model, but we didn’t want something that big.
Do be aware that the ‘power boost’ function is limited: There’s only so much ampage that can be supplied to the rings, so you can’t have them all on ‘power boost’, so they arrange the rings in diagonal pairs, and it’ll alternate which as power for a second. Can be a bit odd to get used to, but makes sense. I’ve never needed them all on that anyway, and if I need two on power, I know how best to arrange things.
Some folk feel that woks are no use on Induction hobs, but we picked up a Ken Hom one, with a flat base of course, that is fine, and we do a fair bit of stir fry cooking. OK, here Gas may win out in the grand scheme of things (ie. the flames heat more of the wok), but not by much: I’ve used both and don’t find it’s that much of a problem.
It’s extraordinarily easy to clean (no burnt in residue as the hob surface simply doesn’t get that hot). The hob is heating the saucepan directly, so the surface is just warmed by conduction from the pan. So much lower maintenance!
A couple of caveats: Induction hobs are quite thick compared to ‘normal’ electric hobs – this is because they have fans underneath to keep the magnets cool. About 1.5″ thick in total (roughly), perhaps compared to a 0.5″ on a normal hob? Just bear it in mind if you’re thinking of getting one.
We were worried enough when our (incompetent) kitchen fitters had mounted the oven right underneath, such that the hob appeared to touch the top of the oven. Insulated it may be, I didn’t want to risk it, so had them lower it to give space. Check the clearance heights and so forth on the model you go for, and ventilation requirements too.
I do sometimes find the water-sensor makes fiddling with the controls a bit fiddly, as I’m not the tidiest of cooks I often have wet hands from washing veg and so on. The water-sensor ensures it all switches off if a pan boils over, so I just need to dry my hands: A fair exchange for a useful feature. The power-on is a half-second too slow for impatient old me. That said, the flush-to-worktop surface makes it integrate very well, and there’s nowhere for gunk to build up which would have been the case if we’d gone for tactile controls.
In short, I love it. At least as good as gas (my view is it’s much better). Very efficient. No gas burning. Very controllable. We’ve not had any problems or hassles, and certainly don’t regret spending the extra money to get induction hobs. Highly recommended.

OK – exactly how long does it take to boil say a pint or a litre of water from cold?
December 10th, 2007 at 10:37 am
Not very long. I have an inch of water in a small pan boiling in around a minute. Water to boil enough rice for two in a couple of minutes. Subjective I know, but everybody I’ve demonstrated the hob to have been impressed by the speed. Throw in the fact that it’s much more efficient way of using energy, and it’s hard to fault.
Maybe one of these days I’ll try and keep an accurate track of the time it takes.

OK, I’m sad like this. Was just downstairs making a cup of tea, and I figured I’d measure the time to boil a pint of water in a medium sized pan. I was using the maximum setting for the ring.
Water was finger hot in ~1min, small bubbles and steam at ~2min, vigourously boiling at 2min 34 secs.

Hi – I’m having trouble finding a cleaner for my hob. Any thoughts or tips? Cheers

I have found that my new induction hob boils water amazingly fast, but for some reason it won’t get oil that hot. I’m not doing anything fancy, just trying to fry some onions in a bit of olive oil, but it never gets to the sort of heat where it sizzles, they just slowly (and quietly) go brown.
Has anybody come across this?

Interested in Wayne’s comment. I have had the same problem when trying to heat oil for the purpose of ‘deep frying’. Chipped potatoes cannot be crisped, but only absorb the fat. I have consulted the manufacturer, followed their instructions to the letter but to no avail. The manufacturer tells me it is technically possible to ‘deep fry’, but they have not responded to my challenge to conduct a practical test and no longer communicate with me.

Wayne’s right it does appear strange but the outcome is the same,as for deep frying what type of oil are you using as vegetable oil seems to work fine with mine.

Doesnt it have a max temp setting? A safety feature maybe? And the bottom of the pan (where the hob senses) gets this hot, the hob stops, and only restarts when cooled enough.. Anything about it in the manual? Maybe try and put a towel under the pan to insulate. Share the results!

Hi there,
I’m at uni at the moment and have an induction hob. I’d like to buy my own pan to use on the hob, but I can’t seem to find anywhere. Do you know any particular stores where I could find the right pan? thanks.

Got a halogen hob, useless as it burns almost everything I put on it. As for gas, Don’t think a professional would use anything but gas. Says something.

Hi
Just thinking of buying my first induction hob. I’ve read some stuff that says they can be noisy if you have more than one zone on at a time. Any comments regarding this? Thanks.

Re. professionals, I note Delia uses induction hobs, and I think masterchef kitchens do. but a professional kitchen is a different proposition to a home kitchen (or a tv chef one), so not sure it’s sensible to draw conclusions. Use what’s right for yourself. But I’d agree Halogen is useless, but it’s an entirely different technology to induction.
Re. Noise – Mine has fans that whir, and the pans make a bit of noise when on the hob. Nothing problematic to me. Gas burning makes a roar after all.

i’ve been reading your forum,am very interested about your amazing induction hobb,how come you are not going on about it anymore?are you still happy with it?will you still reccomend it?
to Wayne and Florence,have you found a solution to the oil problem yet?
