I doubt that second issue. Depending on the insulation, of course, a hot
water tank will hold heat for hours/days. While I don't doubt that standby
losses are an issue, I don't think that under conditions of normal family
use standby losses are greater than the energy it takes to heat the water in
the first place.

More importantly, if the water heater is in habitable spaces then during the heating
season, lost heat isn't wasted. It simply contributes to space heating. The
opposite is true in summer, of course. If the water heater is in a closet, then one
can arrange some clever venting to conduct the heat directly to the attic and outside
during cooling season.
