    Hi,
    I don't know the spin speed on our washer. Its a not too old Maytag Neptune, horizontal axis washer, so I suppose it has a higher spin speed than the older washers, but not sure how much.

    I was trying to think of some simple way to measure the spin rpm, but have not come up with anything -- any ideas?

    I would like to look into the separate spin extractors and/or a newer and higher speed spin washer.

    Seasoned Oak -- can you weigh a load as it comes out of the 1800 RPM washer, and then get the dry weight on the same load? We could compare this to the wet to dry load weight for my washer and maybe get some idea if my spin is low.

    Gary

    Gary,
    I think the pony is in the laundramat!! Just think of the possibilities!...You could use all that dryer heat to prewarm all the washing machine water. Hmmmm. Two heat storage tanks? One to prewarm the water? ...and solar hot water panels on the roof to finish heating the hot water in the second tank? Or a heat pump to top off the second tank that also provides AC to the building in the summer? The sheer number of dryers and frequency of use would probably justify a pretty nifty air to water hx design. With all your knowledge, you could probably design something wicked.

    Make the wife hang your underwear to air dry indoors during the winter and outside on the clothes line during the summer. Done, problem solved by a redneck with no complicated math and weighing wet clothes!! You guys are getting way too into this laundry business!! Get out there and css some cords of wood!! Just joking ya a bit... Good thread and you guys are some brainiacs.

    There is/ was a laundromat near me that has done that for years, probably 20 or more.
