Well, I don't know about 3-phase for a residential water heater. It sounds like the electrician would be a good idea. I do not like the idea of different phase hot lines sharing a neutral or ground wire for split circuits, and especially not for hi-fi. Again, if at all possible, keep neutrals and ground separate all the way "home" to the main ground bus, and configure any sub panels this way, if possible.
3-phase is almost never used for residential in the US, but it is popular commercially to run motors, especially larger motors, but also in shops where motors are running all the time; 3-phase motors run forever, at a more stable speed.
Best regards,
