I don't think they're allowed in my country, although I have seen a YouTube video about them, and seems like people who die because of them die installing them improperly rather than from the electricity.
Still sounds extremely sketchy on first explanation. Water+electricity sounds bad even though it's clearly not in this case.
wait so the electricity is used to heat the water? is this for houses without a hot water heater?
Yeah, it heats the water. I have hot water heater but the pipe that goes to the shower is not connected.
They are super, super common, I am surprised you've never seen one.
You're in the UK, right? In the US our circuits are mostly 110V, so you don't have the kind of juice you need to heat up water quickly.

I've never heard about them before. Maybe it's because district heating is virtually universal where I live and cheaper than electric heating.
