Finally got out this weekend and started my solar project after many months of shopping and studying I found 2 craigslist adds for some used collectors.  The first add I went to was for 8 3x8 collectors that have copper with copper fins in them they are in good shape, going to give the frames a fresh coat of paint and mount them up.  They say on the side of them they were built in colorado.






the 2nd add I went to was for 6 4x8 collectors.  I took one of them apart today.  The tag on the side says is was made in MN from 1980.  The glazing is so old its turned yellow!





This panel that I took apart looks to have had a blow out at one time,  they soldered both ends shut of the broken pipe.



little picture of what happens between aluminum and copper after 30 some years.

Your doing just a hot water system correct? Have you thought about the hybrid air and water ones?

Sounds like a heck of a deal to me, what are the pipes inside the collectors made of?  If copper you did very well!

Yea thanks the 4x8's are copper pipes with aluminum plates and the 3x8's are copper pipes with copper fins.  Plan for today is going to Menards and get the twin wall for the 4x8's.  Also found a craigslist add for a taco controller box and relays to control 4 different zones, he also has a circulatory pump for sale.  I also had a guy that came to my garage sale last weekend and wanted to trade some things,  he is the owner of a construction business that rebuilt our local hospital.  He has all the stuff that got taken down from the old hospital and I am planning to make my water tank out of solid doors that was salvaged also pickup from him 60 pieces of 4x8 2 inch poly iso insulation that has a fire resistant coating on both sides.

Dan also still has (perhaps...) 72 sheets of one-inch glass
that he is keeping very quiet about
