Okay, good deal. So, in theory, an induction stove that’s 3500W should be approaching the heating ability of a typical commercial range.

hinterlufer@lemmy.world 3 days ago1 kW is 3412 BTU/h (=BTUs)
Most induction stovetops have a boost function with around 3-4 kW (that’s about 13000 BTUs).
BUT contrary to a gas stove top, almost all of the energy is actually put into the pot instead of the surroundings (only 30-40% of the energy from a gas stove is used to heat the pot). Meaning that a 4 kW induction cooktop should be comparable to a 40’000 BTUs gas stove (single burner).

Yes, and you can test it pretty easily by just seeing how much faster a pot of water boils on induction, on-par with the boiling times of commercial burners.
Also, in a commercial setting, induction stoves cook just as effectively with less energy which means they don’t put out nearly as much heat to the environment. For a chef, its the difference between working all day in 90-degree spaces to 70-degree AC. I’m an engineer who works on a lot of commercial kitchens (among other things), and our chefs love the electric kitchens we’ve delivered.
When you’re cooking for work, 8+ hours a day, being comfortable while you do it is a major game changer.
The other thing they enjoy is the level of control and consistency - many professional induction ranges will let you control on temperature, which means you can quickly adjust to specific values in order to, say, sear a steak at 500, then finish it at 300 until it hits the desired internal temperature.

So this is 4000 watts? What household circuit can support that?
Aedis@lemmy.world 3 days ago
Idk about my math but most American household circuits require stoves to be on a (220V) dual phase 18 amp circuit. Which should output around 8kW (18A * 220V)

A random Better Homes and Gardens article clocks a 2000 square ft (185 square meters) home with central air conditioning at nearly 19,000 watts.

So I think most homes could handle that in general, but I don’t know about specific wiring requirements to handle that kind of power draw from just the kitchen. So do these things require that level of retrofit?

I’ve never had an induction stove, but I grew up with an electric stove - IIRC, it was on a separate fuse from the rest of the kitchen, and it had a weird plug because it needed a different voltage than most other appliances.
I would assume the requirements for an induction stove are more or less the same… Switching from regular electric to induction would probably be easy, but gas to induction would take a lot more work.

Plenty can. Just need a 240v 30a outlet or higher
Kbobabob@lemmy.world 3 days ago
Which isn’t a thing in the states anyway.
Zeoic@lemmy.world 3 days ago
Yes it is? The US very much has 240v for power hungry stuff. Things like ev chargers, central ac units, water heaters, electric clothes dryers, etc. It uses quite the variety of different plugs for the various amperages

That is exactly what I have running to my traditional electric stove and I live in USA.

Uhhh, tons of people in Europe are on 240V 3 phase power.
My oven is 3100W and that is just fine. 3 phase consumer induction cooktops can easily go that high or higher.
Once my 3 phase charging pole is put in, my car will charge at >10000W on a household circuit.

Here in Italy most houses used to have contacts allowing max 3kW, but nowadays it’s more common to have 4.5kW (with smart utility meters which allow 30% over current for 3 hours).
Still have to be careful if you’re running a washing machine or something like that, but it’s doable.
Of course old houses may have insufficiently-sized wires, and that’s another can of worms.
