Almost has to be. 2400W would put it completely outside the consumer market. Consumer PSUs don't go that high. Home power outlets don't go that high unless you have special electrical work done. I can hardly imagine what a cooling system for a nearly 3KW system would look like.
In Europe, this is no biggie
I just saw a reputable 2400W kettle on a random online store for 50€
Looks like there are 3000W options too
Oh! I knew European outlets operated at higher voltage, but I didn't know the standard circuits supported such high current. Jealous!
I live in a 50 year old house. All the breakers are 16A, so 220V x 16A = 3.5kW
The electric sauna does three-phase @ 400V. My energy tracker usually peaks around 9.5kW when it's heating.
Nominally EU voltage is 230V, and may be 240V. In fact, it can be as high as 230V +10% = 253V. Higher voltage means more power for a given current, so nominally it's 16A x 230V = 3.68kW, but you could have say 16A x 250V = 4.0kW.
If your sauna is 400V then it sounds like you'll be 230V (400V / sqrt(3) = 230). But the voltage can also be 230V -6% = 216V, so 220V is within scope.
But yeah, standard voltages in the EU are either 230V/400V or 240V/415V. They've been harmogenised, but if you look at the numbers you'll see the trick - 230V +10% is roughly the same as 240V +6%. So the range is 230V-6% and 240V+6%.
You've got a 3 phase connection though so you might find you've got different single phase breakers on different phases (eg lights on one phase, sockets on another), with slightly different voltages for each one.
