Switching to induction - how did it go for you?

I have no idea what you mean by humming and I find no residual heat very practical. You don't burn yourself.

Many reported that you can practically hear a "humming" when cooking on induction.
But that can also depend on the pots used.

If touch is too fiddly for you, Neff has a clever solution with a rotary knob that can be removed (called "Twist Pad").

My current cooktop is also a Siemens cooktop with touch and I like it very much.

Swedes and I was very surprised HOW loud they are.

Is it the cooktop or does it depend on the cookware used? I haven't heard so far that cooktops themselves can also be loud.

New pots were overdue anyway.

There are many pots that are "induction-capable," but I somehow still have to get my head around what the differences are.

Important, check if all your pots are induction-compatible. We had to part with two beloved roasters.

Is "induction-compatible" enough? Aren't there pots specifically made for induction so they don't buzz as much, or does it not matter and is it the same for all?

I also have a few traditional cooking pots that will definitely have to go :(

No, there are differences. Especially the ones for 20 euros.. with those you’ll rather damage the cooktop because you waste so much power. Especially the older ones it was a problem. My girlfriend got a wool pan, that’s the difference between night and day. I used to have an old induction cooktop, with those 20 euro pans it was always a gamble if they would be recognized. No problems with branded stuff. And the good old enamel pots.. In summary, it’s clear, it’s a high-frequency magnetic field that is generated.

Is it the cooktop or is it due to the cookware used? I hadn’t heard that cooktops themselves can be noisy.

The cooktop itself is only audible afterwards (when the motor is "cooling down"). During operation, when nothing is on it, no, it can’t be, it then switches off... I only had (cheap) 2 pans (Kitchen Aid and a no-name brand) that are induction compatible, so we bought a complete Woll set (for my standards something reasonably high quality). All pots and pans are equally noisy.

The humming is gone. It's not like it's the only noise anyway. Extractor fan, sizzling, etc. Induction repeatedly. The quick response is great, but never touch control again. I'm not sure if our cooktop will age well.

The buzzing also partly comes from the pan/pot on the glass surface. So if the bottom is not completely flat, it vibrates due to the induction on the plate. Roughly, the formula is: the more expensive the pan/pot, the flatter the pan/pot bottom, the quieter the buzzing... My cooktop is currently from Amica, and the cooktop itself also makes a bit of noise but is quickly drowned out by the ventilation of the cooktop when cooking for a longer time at medium or higher levels.
