Good of you guys to pick up on that subtlety, i.e. warmish water is a
good place to grow bugs. For my system, I only fill my "tank" (a 20
quart aluminum stock pot) when I'm headed off on a trip, usually for
several days to a week or so. Use it every day or twice a day,
usually. I noticed early on that if I left water in the tank after a
trip, which previously had several heating and cooling cycles, the
interior of the tank (which includes the 12 VDC submersible bildge pump I use for a powered hot water shower) would sometimes develop a "film" of slightly slimy stuff when checked a week or so later. And this is
using chlorinated tap water, although I'll use whatever water I can
find, including rivers, streams, gas station fill hose for radiator,
etc.
So my solution is to dump all the water out after a trip,
maybe even sponge dry the interior, then let it air-dry thoroughly.
This seems to work fine.
BTW, I only use the 120 degree F water
for hot showers....never for cooking....but would be fine with rinsing
dishes, etc. as I dry these with a paper towel before putting back in
cabinets.

I agree with you Mr. Bell, I'd only want the heated water for a short
interval like start
heating the water in advance of an anticipated shower then use it and then
drain the
rest or whatever would be best to keep the system clean. Kind of like
what is done with
the fresh water holding tank.
