Btw, why don't things like this, with short usage time but high current requirements, not have a (big) built-in capacitor to "pre-load", to shorten the heating time and put less load on the house circuits?

Edit: added more context to why.

[โ€“] Randelung@lemmy.world 7 points 4 months ago

Because the current requirements are constant and not like a photography flash just a short but extreme amount. There's no point in putting a few Watt seconds into a capacitor if the power requirement is 2kW for minutes.

Plus

  • power storage is large
  • you need a way to transfer the stored power into the water faster (otherwise why bother), which means thicker coils and more wear
