[RE-wrenches] Outdoor rated insulation covering for Solar Water Heating Systems

[cwarfel]

I thinkthis problem is really only "solved" by using the coverings 
suggested, especially it seems, aluminum jacketing.  I will be going off 
island in a week and I will have the chance to go to a store that sells 
these products. I am hoping to put this system into HomePower, so, this 
will be part of the article. Thanks for everyone's responses. I 
hopefully responded to everyone off line. Stay tuned.  Chris
