These coils (however powered) will freeze moisture out of the air just like
any non-self-defrosting reefer.  But to get that much in four days is
strange; they can't freeze out moisture that isn't there.  Are you keeping
pans of hot water there for safekeeping? <g>  Somehow water vapor is
getting in there -- no door gasket?  Mischievous demons?  My guess is that
you have considerable air leaks at top and bottom of the door, which could
set up a convective loop and pull air through.  Hey!  You've just invented
the dehumidifier, door-to-door service and flooded basements our specialty!

Nope.  It uses lots more gas in hot weather.  About a couple weeks per tank
in New England summertime, vs a month or more in cold weather.  The flame
gets much bigger when it's actually trying to cool.
