Along the solar supplement route, I saw in one of my "good surplus junk" catalogs a freon/water heat exchanger, that supplemented your water heater by dumping reject heat from an air conditioner. So, cuts operating costs and can make your air conditioner cycle more efficient.

Probably this is the wrong list for you, but you're fiddling around the
wrong end of the pipe. You should be going for the most efficient water
heater, the cheapest fuel and minimum heat loss between the heater and
the shower head. Remember to shower Navy style--spray first, shut off
the water while you soap then rinse off real quick.

Evaporation rate is strictly a function of relative humidity, relative
temperature and droplet surface area. You can't do much about humidity
and temperature. You can minimize evaporation by not using a spray
nozzle altogether. That will reduce the droplet surface area for
evaporation, but of course it reduces the amount of hot water you'll
rinse with. so you may have to run it longer. I've seen systems where
solar heat is used in a pre-heater, or you might consider going to
solar altogether, if your weather permits.
