“[Here] is a pix of a salvaged solar hot water collector I rig up to heat water to wash fleeces. It will heat 10 gal, a wash tub, to 110-120 degrees in a couple hours or less. Three or four wash tubs per sunny day, 10 a.m. – 4 p.m., enough to do a fleece. And, of course, the more collectors, the more hot water.
“The way to get collectors is to talk with roofers. They take them off to reroof. The people they work for didn’t buy the collectors, the system is often dysfunctional, and they give them away.” – Bill Hurrle
