I would like to buy one of those electric faucet water heaters for my parents.
But I'm very concerned about if they are even safe to use and some questions came into my mind:
- how is the internal wiring shielded from the water?
- how dangerous would it be if the cables which goes to the heating element get in contact with the water?
- why are they (as far as I know) only available in China and not at my local hardware store in Germany?
(maybe off topic but is it even legal to install/use them, also regarding to insurance?)
