I would also like to insulate the tank so it will not sweat during our hot,
very humid summers. What would be the best material for this? I do not
want to harbor mold so I would like to keep air from getting between the
insulation and the tank.

I don't like Harbor Mold either, even though Harbor Freight seems
pretty good.

AFAIK, mold requires something to eat, and won't grown just anywhere,
even if it is wet and dark. And it can't eat fiberglass, so a water
heater blanket sounds fine to me too.

When I have had mold it's been on sheetrock, and when I've had mildew
it was on a thermal blanket of mine that my idiot roommate found in
the closet and used to soak up dribbling from the steam radiator, and
then just left there for weeks.

(BTW, the blanket smelled disgusting, and I washed it in a machine and
it smelled just as bad afterwards. Then I dried it in a dryer, not
even especially hot, and it smelled just fine after that. Never even a
trace of the bad smell for years after that. Thoough a portion of the
brown blanket was now white.
