Induction Cooktop: Burner & Pot Size Matching?
Comments (74)For searching out info in the future, it might help to know that "induction tabletop units" are often referred to as "portable induction cookers" which sometimes is abbreviated as "PIC." Now, on your questions about pans, are you looking for a way to heat several pans together on a single induction burner? If so, the caterer's serving pan idea won't work any better than it would if you used it over a small gas burner. Induction heating is not passed by magnetic contact between pans over a PIC --- well, only on such an infinitesimally small scale as to be of no perceptible use in cooking :>). Basically, the strength of induction fields falls off so rapidly that it has no heating effect on pans more than a fraction of an inch above the burner surface. For the same reason, stacking pans won't work either. Further complicating things for you, your PIC may claim to be a 9-10" unit, but the actual induction field on them is only 3.5" to 6" (depending on brand.) Beyond that small field, you have to rely on your pan's mass and conductive abilities to spread and transmit the heat widely. A stainless steel caterer's serving pan is just too thin to function that way. IOW, it won't work like an induction adapter disk (which basically converts the induction heating into a radiant electric surface.) In theory, something thicker might work as an adapter, such as one of Chef King's rectangular, 14" x 23" carbon steel stovetop griddles (about $70 last time I checked). My experience with this kind of thing has been that these can heat other pans but so slowly that they work better on PICs as warming trays rather than for bringing other pots to heat. Frankly, it might be easier to heat up each pan separately on the PIC, then put on the caterer's pan with hot water, and use the PIC to heat the water that will keep the pans warm. If there is a second electrical circuit, you also might consider buying a second PIC. IIRC, there are some Duxtop units which have pretty good reviews and now are priced in the same neighborhood as the Chef King griddle that I mentioned above....See More36' Gaggenau or Miele Induction Cooktop?
Comments (34)In Austrailia warenty was only 1 year bought 2013 just under 12,000 AUD dollars it never works latest quote to reapair 1600 dollars , over the past year I spent 3160 on diferent reapairs down time nearly 7 months ( lucky I had my $200 plug in fryer ) I'm going to throw my gaggenau cooktop it in the trash & buy a new cook top defenetly not gaggenau . I do have the oven & the steamer they do look good , but for a functioning kichen , a kichen that prepares meals for a family gaggenau is not the product no matter how healthy one is one still what's its products to work...See MoreScientists? Concerns about induction and gas cooktops
Comments (33)This is a quote from a previous garden web posting: *******Safety of electric induction hobs questioned in Japan 'IH cookers generate electromagnetic fields [in the frequency range of 100Hz and 18-23kHz ] when an electric current flows through coils under the top plate. Heat is created when the electromagnetic field reacts with the metallic pan atop the plate. (For the young, whose more sensitive hearing will be able to detect this level, cooking using an induction hob could well be accompanied by a rather unpleasant whine). Whilst there is not a unanimous agreement that EMFs are linked to health problems, neither the government nor industry seems willing to make attempts to limit electromagnetic field exposure from IH cookers, both sides boasting of the products' safety, while saying it is the responsibility of the other party to communicate possible risks. Takenori Ueda, of the Japan Offspring Foundation which reported the finding earlier this year, added that IH devices emit the highest level of radiation among all household electric appliances. Microwave ovens are more powerful, but their emissions are countered by stronger shielding. The Foundation tested the hobs with a radiation measuring device placed right next to the cooker set on maximum heat with a 12-cm pan on it. All products registered incredibly high radiation levels, some as high as 101 microtesla. The highest level was more than 16 times the limit [for 18-23 kHz frequency] set by the International Commission on Non-Ionizing Radiation Protection for short-term exposure to such fields. The companies accepted the Foundation's findings but insisted that the ICNIRP guideline can be interpreted differently and that radiation levels do not exceed the limit when measuring devices are placed 30 cm away from the device. The Japanese government says that the industry or individuals should do something about it. The Japan Electrical Manufacturers' Association say that if there is to be a framework for more stringent safety measures regarding exposure to electromagnetic fields, the government should take the lead in drawing it up. A spokesman agreed that manufacturers have failed to provide consumers with sufficient information on electromagnetic fields. Koya Ogino, a Kyoto University lecturer who specializes in electromagnetic fields, and the potential adverse health effects from long-term exposure, criticized both the government and industry for not taking further precautions. 'If the companies are profiting by selling the products, they should first confirm their safety,' he said. The Japanese Government's defence is that they are awaiting 'more proof' of possible harm -- which is expected to be the result of 'current research' between the WHO (World Health Association) and the ICNIRP...... The Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) is shortly to take on the task of writing a new ELF exposure standard for Australia. If they just incorporate the ICNIRP limits, which is very likely, will this then make the sale of induction cookers in Australia illegal?'

Comments (30)I'm responding to venmar's question: While all of the above comments are true, I do have to wonder why some of the GE and Kenmore branded version induction cooktops from the early 1980's are still functioning while our modern equivalents are so fragile and short lived. Well, actually, there will be some current induction ranges that will last just as long as some of the first gen models you mentioned. Note that I said "some." Seems to me that in any given electronics product line, some units will chug on for a long time and some will not. One of my aunts still has a functioning early Kenmore induction range. (FWIW, it was my intro to induction cooking appliances three decades and something ago.) So, the last time I needed a new stove, I looked into maybe getting a "pre-owned" Kenmore induction range from the 80's. A bit of research showed that every story of longevity like my aunt's was swamped by many tales of woe, of gnashing of teeth, of unrepairability, etc. etc. My take away is this: it is really hard to say if all of our "modern equivalents" really are significantly more fragile and shorter-lived than the older induction models. Or older stoves generally. As plllog says of fridges, nobody really expected a Kenmore to last for decades, even the older models that didn't have any electronics, but some of them did. That some antique appliances are still around and working doesn't necessarily make them better than the current models. That being said, I certainly see the appeal of Venmar's vintage back-up coil burner range for simple reliability and durability. It is not just induction, either; it is pretty much all major brand appliances which run off circuit boards. But there will be tradeoffs. The extent of those trade-offs may or may not be worthwhile to any given one of us. As appealing as the simplicity and reliablity factors can make a vintage range seem, there are still some major trade-offs in day to day cooking such as waste heat, slow responsiveness, uneven ovens, etc. Seems to me that this is pretty much applicable to all appliances. Fr'instance, even with all my neo-luddite tendencies, there is no way I would trade my current Kitchenaid/Whilrpool FD fridge for the 1954 Westinghouse chill chest I had in graduate school 40 years ago. The problem as I see it is the uncertainty. There is no way to know if your unit is going to last a long time or fail early. That is why I find myself nodding in agreement every time Kas says "I now consider these cooktops to be effectively leased . . ." Regarding Kas' s comments about GE maybe building those old induction ranges better, my recollection is that those early GE and Kenmore induction ranges were actually rebadged units built by Sanyo in Japan....See Morekevin9408
