The instruction manual says that rotary dial for the left hand heating element goes from 800-5000W and the right hand one goes from 800-3500 (when both are used they are capped at 7000w, and the right hand element will only draw 2000w)

Q about a commercial induction hob

From your first link, just below the image of the product, there is a hyperlink that says product attachments.
The following is the user manual.

There are any number of domestic induction hobs/cookers sold here, which are wired to a normal 32A cooker circuit, and which have boost functions to up the output of one element by sacrificing the performance of others. 3.5+3.5 = 7+2 = a piddly electric shower.

Well, the circuit diagram doesn't show a neutral. It's a bit vague though. (I think it said 380-400V, and shows 3 wires A, B and C.)
@morqthana What has the seller and / or manufacturer of the appliance said?
You have asked them, I assume? Almost three working days so far...

Anyway, decision now made, hopefully (I thought it was made last year, I'm not that dithery, but it fell by the wayside when the chosen products became unavailable).
But given that during the (now 2
) decision making processes I found that makers of "commercial" cooking equipment sell 7kW 230V units which are clearly 2 x 3.5kW units in the same box, and sometimes need 1 7kW supply but sometimes have 2 13A plugs on them, I don't think my initial question was unreasonable.

My suspicion is that they are mostly , most likely, 240v (230v) heating elements that could be wired for either single phase or three phase as required in any installation and I suspect that many of them would be “happy” running from a. 2 phase split supply anyway . That’s just considering any that have a N connection and also considering just any that are purely resistive elements.
In the same way that the European declared voltages tend to be 230/400 but, in reality, they are pretty much what each country (including the UK) had before “harmonisation “.
If we consider any that have “clever electronics” before the elements then they might well be suitable for a good proportion of any world wide supplies too.
A manufacturer might consider selling just to one country or one group of countries or to many/most countries and consider the additional cost versus production runs dependant upon their volume of sales.
Only they can decide the most cost effective ethos in this matter and design their products accordingly.
It used to be the case some years back that in the UK we could buy a roll of pvc cable and single and earth cost more than twin and earth so some folk would just buy twin and earth and not use the extra core. Similarly 5 foot fluorescents could be cheaper to buy than 4 foot fluorescents despite more materials being used in the units of a 5ft than a 4ft because production runs of the 5ft were far higher than the 4ft.
Similarly, apparently I was told, that some appliance manufacturers such as Phillips etc when making the older TV sets (say 1970s) used to sources components such as carbon resistors for example and carefully look at the price breaks quoted to them.
If they discovered that, for example, they needed 450,000 of a particular component and they checked the resultant unit price of say 500,000 and compared that to the resultant unit price of 1,000,000 then as expected the higher batch quantity was cheaper but they also spotted in some cases that the total bulk price was also cheaper too so they might buy 1,000,000 and throw 550,000 in the bin.
Later on some of them over ordered to get best value but instead of throwing the surplus in the bin they would sell them on to other firms such as hobbyist components suppliers at vastly reduced prices and they in turn had lower cost items to sell to the hobbyist. Everybody wins! ?????
Of course that was back in the days when accountants could have a beneficial input in large organisations both for shareholders and customers. Not sure we feel about the same of them these days though
.
In fact one daft example of this (my own personal experience and I chuckle about the shop owners exclamation.
For a for years in recent history, I used to make an almost weekly visit the our local kebab takeaway.
Instead of buying donner kebab in a pita bread including salad (and fries) I’d worked out that it was cheaper to buy the items individually from the menu.
After ever all months the owner began to appear on site at busy times and I noticed a few times he seemed to take some interest in what I was buying and then one week he served me himself (this is the funny bit). I asked for a tray if dinner meat and a tray of salad and a pita bread separately and a bag of fries, he exclaimed “that’s not fair! You are buying a donner kebab for 50p cheaper if you order the items separately!”, my reply was “yes, you have priced your menu and I have ordered accordingly, not only that but I sometimes buy two bags of fries and that makes meals for two people not only 50p cheaper but a free donner for the other person too”.
He was livid. I was not being fair ordering from the menu he had created? LOL.
Some of you will know that because of my age I am from the “save a shilling” era but my father in law was from the “save a farthing” era.
In later life he became part of a family firm selling tarmac for driveways, the team would set off early morning and load up the hot tarmac fir the day then call in at the same “greasy spoon” as usual and each order a breakfast, eat it then go do their days work.
One day my father in law ordered the breakfast special but decide he wanted no baked beans with it.
When it came time to pay he found his cost him 50p more than usual and more than his comrades had paid.
When he queried the extra cost with the owner he explained to him that the price menu was made up of individual portions according to what he had ordered but if someone had the full breakfast it was a special discounted offer off the full price, as he had not had the full Monty he was paying the individual prices hence it cost him more.
He was incensed by the buy less pay more of the situation and he went on about it to us for weeks 2 or 3 times per day.
That made me laugh as much as about the kebab takeaway.
I did advise him in future order the full Monty then give his beans to one of the other lads at the table.
