if you don't like the idea of 16' of 1/2" underwater plastic tubing,
you might make an exterior heat exchanger from about 4' of 3" pvc pipe
inside 4' of 4" pvc pipe, with 2 reducing ts and male adapters so it
can be unscrewed for cleaning. pump the inner hot water loop, and let
the outer hot tub loop thermosyphon.

i still like the idea of lining the ultimate clothes closet destination
with foamboard and putting a couple of hundred watt light bulbs near the
bottom, in series with a humidistat. take the clothes out of the washer,
give 'em a shake for wrinkles, and hang 'em up on the pole.
