They’ve got a quite unusual stove that’s got a large battery in it so that it can operate when the power is off, and doesn’t need the installation of a 240v power connection. This avoids the cost of an electrical retrofit of old apartment buildings, which otherwise costs far more.
If you’ve already got your home wired for 240v, you can get an induction stove for far less.
These battery-equipped stoves are expensive right now because they’re being made in quite small numbers. The parts needed are coming down in price quite rapidly, so I expect to see them sold in the $2000/unit price range within a few years.
Almost every American home has 240V coming in, with 2 hot wires with 120V AC exactly 180° out of phase with each other, and a neutral wire that’s supposed to be roughly ground voltage. The standard is to split the 240V into 120V for each circuit at the actual breaker panel, by feeding each normal circuit in the house one hot and one neutral wire. But setting up a particular circuit for 240V service is trivial by using both hot wires.
And the actual distribution grid itself, before it hits the transformer that steps it down to 240V right before actual customer meters, is going to be much, much higher voltage in any country. Higher voltage means less line loss, so power lines use high voltage. That part doesn’t differ significantly between countries.
Anyway. That’s why most American electric stoves and ovens are actually 240V.
I know that our Electric stovetop is connected to the 400v Three Phase circuit.
So even with 240v mains power the Stove is usually connected to a circuit with the highest available power.
But even the 240v plug in induction stovetops have plenty power for cooking.
I’m curious whether voltage even matters, and what the wattage of each burner is, and what the total power max for the whole stove is.
A typical US stove draws either 40A or 50A at 240V, so that’s a max power of about 12,000W. But each burner is usually limited to something about 5000-7500W.
With induction, the heat is efficiently placed right into the pan, so actual performance probably matches a lower nominal power resistive stove (or gas stove).
