Yup.

Yes.

The water heater temperature-sensitive switch might not like DC since it
will tend to arc. What you use to charge batteries determines whether you
can charge with DC. A 60-Hz-transformer-based charger will not work on DC.

There are PC power supplies which accept DC only. Depending how they are
built, "normal" PC power supplies may accept a DC input just fine, but it
will likely need to be 170 VDC.
