I mean I know things are different here in Europe but 18kW for a water heater? Why? I have one that plugs into a regular outlet, so no more than 3.5kW, and I have no issues whatsoever. Sure, water isn’t boiling hot out of the tap, but I can take showers no problem and usually need to mix a little cold water to make it comfortable. Why would you need any hotter water? Or is there some other reason why you need so much more power in an american system?
