The induction cooktops are a world apart from the resistance heated cooktops (glass or otherwise). You'll find other than having to be more careful about pot/pan selection, your induction is as responsive as your gas and has some neat extra benefits.

It depends on the unit, but many actually do have a proportional decrease in power at 208 compared to 240. You should address that question to the manufacturer. However, even at the reduced power, the induction is still a win (and the resistance cooktops DO suffer the same degredation).

These current numbers are maximums which assume all elements are running at maximum all at the same time which is fairly unrealistic. If you are a normal two medium burners plus a 400 degree or less oven sort of cook you will never have a power loss problem. (I have an earlier equivalent of the Kenmore MD30 and have had no problems.)
Be aware that the Electrolux and its Kenmore clones have an oddly shaped top which can give you problems fitting it into a normal counter. It would also be wise to consider an extended warranty and avoid the maximum time sessions of self cleaning too.

Any induction range working on 208v will be a bit slower acting than on 240v but is still much superior to a radiant range in performance. I'm sure you will enjoy your new appliance.

Yup, look at the specs and talk to the manufacturer. Keep in mind that some of the multi-hob equipment will only operate hobs at full power when less than the full complement is being used. The power supply can chop power to some of them as more demand is added. I can't imagine that the power supply will not adjust to give you full power on any one, two or maybe three at a time. It just might run out of power 'sooner' at 208 than at 240.

You should get a lot more out of the induction range than a standard electrical resistance range. One often overlooked advantage is lowered HVAC costs due to more efficient heat transfer.

I tried chatting with a tech from Samsung. I asked specifically about induction ranges and he came back and said "let me inform you that all the Samsung TV manufactured in Canada supports 120 volts power supply"
I know that is accurate because the conversation was so bizarre that I took screen shots. the conversation went downhill from there. at that point I could not trust any of the information he gave me.
Thanks for the input from all of you; I trust your advice far more that that which i got from Samsung

It might help to look at the numbers. Then again, I don't know how the oven integrates into this so we might be even more confused at the end.

At 240 V 40A you would have 9600 W available to the range. (That assumes a power factor of 1. That is not true, but it is all I have to work with.) at 208 V you have 8320. That is a 13% reduction. Your range top appears to operate like a typical cooktop or two-hob portable induction cooker. There are boost settings that temporarily increase the output of individual hobs. (Probably until the power supply or induction coil approach overheating.) Total of the boosted output of all of your hobs in this range is 9900 W. "Normal" output total is 7100 W.

I don't know what the power needs are for an oven resistance element. Maybe someone else here does. I'll assume that it is 3000 W. I think that is conservative. It is obvious that this range is designed to output, using the 3000 W figure, a maximum of 6600 W to the hobs if the oven is on. It can do that in two ways monitor the oven element power or simply limit the hob total to 6600 W at all times. It is obviously impossible to operate 4 hobs at full normal power all the time even with the oven off.

In fact, the range can not draw the full 40A continuously so 9600 and 8320 can be used only for a short period. I predict that at 208V you will just start to run out of power sooner as you put higher demands on your range top. What that means precisely, depend on how the higher demands are made and how Samsung programmed the appliance.

If you go to the link that I posted above, I think that you can find a discussion about power sharing between hobs. While it might be nice to know how Samsung does it, I am sure you will be happy with an induction range. I'd certainly like to know how the oven is factored in. It is something I've never thought about.

If you want to test induction cooking you might consider getting a plug-in hob. While you will be limited to 1800 W with a residential type unit, and possibly 2400 W for a 20 A commercial unit, you will get an idea how well it works. The hob may come in handy even when you get the range for the days that you might want to off load from the range top so you can crank a couple of those positions up to their boosted 2.3 kW outputs at the same time :-)

I had a residential type portable. Now I have a Max Burton 6500. There is really no comparison in operation. The former used to shut off when I had an iron pan on it to cook a steak. It overheated. The Max Burton has not done that. It is much more robust.

Customer service can be so sad. I remember that Aervoe (Max Burton) was excellent when I had questions before buying.

OMG! just got off the phone with Bosch. He tried to fob me off on the dealer because they (at Boch) don't have the technical information............. WHAT????? (who do I have to ask? Mr. MaGoo?? He said they train the dealers to answer these questions. as I had already talked to 3 dealers, I asked to talk to the guy that trains the dealers but, sure enough, they don't know who that is. Perhaps, they suggested, I should talk to the people on the desk that assists people with installation problems........ WOW!

SOLUTION: ignore the people who don't know about their products and really have no interest in finding out. I am going to listen to you folks, get a range and live happily everafter. of course if I am not happy everafter I can always return the range!
Thanks for your input and help everyone here! (not so much for the customer support at Bosch and Samsung!
