If I use a 50 pint a day dehumidifier twice a day (I need to, to keep on top of molds and spores, plus to keep everything down below aired as much as possible, so usage will revolve around two
cooking periods to tackle the steam), I'll be able to get about 8 pints a day off it, from 2 x 2 hour sessions. Bacteria,
mold, and spore content may be quite high though.
I'll save the water into 6 gallon jugs, and when near full, will add some chlorine to kill any nasties. It'll be handy for clothes
washing, showering, rinsing off the
anchor and chain,
sails, that sort of thing, and will help extend the duration of the water in the
tanks.
In an
emergency, I can always put it through a water purifier like a Berkey, plus it will be handy for topping up
batteries.
It isn't going to throw a
reverse osmosis watermaker from near the top of my 'future purchases' list though.
