Bosch 300 induction top & my new cookware (long)
Comments (14)sf3707: To add to what MizLizzie said, you might have a look at the link below to Bosch's specs page for the 300. It says the front left heating element (the 9" one) is rated to 2.2 kW (2200 watts) and can be boosted to 3.3 kW. The right rear (11" burner) is rated for 2.4 kW and boosts to 3.6 kW. The two 6" burners are rated for 1.4 kW and boost to 1.8 kW. You might also want to download and read the User's Manual for the 300 series induction cooktops. Go to this page: https://portal.bsh-partner.com/portalbD1kZSZjPTAwOQ==/PORTALFRAME.HTM and download the second item (the one with the biggest file size). As for using a 12-inch frying pan on the 11" burner, there should be no problem. As MizLizzie says, there shouldn't be any problem with using a pan large than the burner diameter. When MizLizzie pointed out that her Cuisnart pan was more than 12" across the base take that as a significant point. For induction burners, the important measurement is the diameter across base of the pan, not the ultimate diameter at across the top. Most 12" frying pans are measured across the top, but it is the size of the magnetic base that the burner's "pot sense" function will "see." The bases of many stainless steel 12" skillets will actually be about 9 inches or less. My cast iron 12" skillet is bit larger -- roughly 10" by my measurement and use on induction. Anything over 7.5" should be fine on an 11" induction burner. No problem with using the 9" burner, either. The one caveat is that, depending on how the pan is made and the amount of preheating you give it, and the kind of cooking you do, you might (or might not find) with a digital thermometer gun and a pan whose base is more than 12" across that the very outer edges (the parts beyond 12") might register a little cooler than the parts within the 12" area. This is very much a YMMV thing. For me, it has never been noticeable for what I cook, and does not seem to be one for MizLizzie, either, but other folks have, from time to time, seen this as an issue for their cooking.

Comments (15)Hi davidrol, Don't know whether this is still an active post, but in case others are concerned about noise, I came across this at theinducttionsite.com: "Noise Induction itself is a noiseless process: the energy fields are generated by electronic equipment, which is silent. But even efficient electronics generates some heat. Whether the amount of heat generated can be dissipated "passively" (just by radiation and natural air flow, still silent) or requires a small fan to augment the air flow depends in good part on how tightly a given maker has packed how much power into how much space--some units have fans, some don't. But even on those with fans, one, the fan does not necessarily run all the time--usually just when the unit is running multiple elements at high settings--and two, such fans are normally pretty soft-sounding. There can also an occasional very soft "tick" sound, as the power controller cycles the elements on or off to keep the element power steady and stable. What can sometimes produce sound with induction cooking is not the induction equipment but the cookware itself. Some of the possible causes include: * Encapsulated slugs in the base of the cookware: "clad" cookware (which is what any stainless-steel-finish cookware that works on induction is) has as its base a sort of "sandwich" of layers of several different metals (typically steel outside, aluminum or sometimes copper in the middle, and more steel inside); if the middle layer is merely encapsulated in the steel, as opposed to being actually welded within it, it can move about, however microscopically; but any such microscopic play can give rise to a sort of "buzzing" noise. On some other cooking surface, that buzzing won't happen, but the high-frequency oscillations of induction's magnetic field can cause it in lower-quality clad cookware (but even then, only on higher-power settings). When it occurs it's not typically loud, but it can annoy some people. Again: it's not the induction equipment, it's the less than ideal cookware, but it is an induction-related phenomenon. * Loose-fitting handles on cookware, typically when riveted on, can vibrate slightly. * Pans with irregular bottoms can vibrate audibly on the glass surface, though again typically only at high-power settings. * At high-power settings, lighter-weight lids may occasionally vibrate a bit. Cookware of solid cast iron, including enamelware, is not subject to such issues; and clad cookware of the top lines should not be."

Comments (15)Can't say for sure without direct examination or comparison to the sound of the pump on Day 1, but from this position afar, I don't think there's a need to stop using the machine. The sound is very much similar to the pump on my Neptune TL and a friend's Neptune frontloader ... resonating of a pump motor mounted to bottom of the machine's cabinet ... but perhaps a little louder. Unlikely there's a start relay on the pump, they're typically a shaded-pole induction motor. Your choice to call for a service appt for your peace of mind and to confirm if there is/is not a problem. Myself, I'd keep using the machine as-is until the situation gets obviously worse (because it may not) ... as in the pump either leaking or going dead. Or better, I'd break into the machine and examine the pump for evidence of a problem ... but I'm a DIYer and you may not have the ability....See MoreLacanche induction buzzing?
Comments (4)Adding to what Juneknow said thin pans or kettle on boost or hi from a cold start will make more noise until either warmer or you have reduced the power, in either case not annoying just a fact. When using cast iron I have been told to start on low power, say maximum of 3 for a minute or two before upping to medium 5 with probably a top level of 7, your cast iron will soon be sizzling at that level. In any case NEVER use boost on cast iron. When cooking an egg dish in a small cast iron fry pan I find after a brief heating at up to 5 l am back to 3 or less to finish cooking....See MoreHobie Webern
