My "favourite" are electric tankless water heaters... *shudder*
400V 3x35A, 21kW...
A pressurized electric storage tank would probably the most comfortable option where gas is not available.
The classoc 5 or 10l open electric tanks (the ones that go in our hardware stores for €27.90) are pretty useless for a shower and the matching faucets pretty much even out any price difference.
We have one of those on our workshop sink... I still want to strangle the unknown person who replaced the old gas-fired Ascot with that electric trash! (Not to mention the gas pipes were brand new whereas the electrical wiring was some 80 years old and scary as could be)...
