Gas Dryers and Washing Machines [RE-wrenches]

Wed Aug 30 23:17:34 EDT 2000

The last info that I had on the Neptune is that it is NOT an efficient
washer. It draws considerably more than the Staber and a HUGE amount of
water, I have been told that it constantly replaces water to cut down on
sudsing.....  So it uses lots of water and pump run time.

>Travis-
I agree with leaving the dryers out of the calcs, as they will
typically be used in the winter when solar is minimum.  We do include
the washers, however, as many of our customers do run the washers off
their systems in the summer. Wind systems, of course are the
exception.  The 100 watt-hr for the Neptune washer seems really low.
Where can we get these? I don't think the Staber could be any less.
Regarding the refrigerators, I think lots of progress can still be
made besides motor improvements. Check out the Sunfrost: two
compressors and the evaporator, top-mounted, 3-4" urethane
insulation, and lack of thermal bridges- all of this could be
incorporated into conventional units, without increasing the cost too
much.
