Well, here we go again, glad no one had rubbed it in that I used cold water pipe.  2or 3 yrs back I redid collector # 1 with cpvc, cut all the can coverings off, replumbed, and now rinse lather repeat for unit 2.  They are both approx 8x8 units.

Hopefully I can post multiple photos below.  This thing had been leaking at a compression coupling in the upper right quad that i attempted to fix a couple of years ago.  The comp coupling held up pretty well, but for last 4 months I had to do something.  

Felt paper going back in under my new piping and more beer cans will be wrapped and siliconed to the new piping.  I hope this is the last go round.  I've had no problem with the first one since replacing that cold water pipe.

Thanks all for viewing!

Decent progress on the pipe replacement this weekend.  Sat got all inner collector plumbing connected, (connecting the 4 quadrants), got new holes drilled for pipe drain holes and new entry pipe location. Scott D had asked on my other build if this was plumbed in series, I was never sure so never answered.  Tonight looking back thru my original build pics, I "guess" it is.  I'm not an electrician, but I think that is an appropriate term.  (Guess tonight I was thinking about golf cart batteries when that came to me.  The  lower left quad exits at top and is pumped thru lower right quad (entering lowest point left of that quadrant), then feeds up into upper right quadrant at it's bottom and is pumped into the upper left quadrant(at it's bottom), exiting at it's top and then goes back to the coil in my thermal tank.  The only downfall of this design is I have to have a separate "DRAIN" pipe for the upper left quadrant.  So seeing 3 pipes to the left of the photos may be a bit confusing.  One pipe is only used for FREEZING nights when I shut the system down.  I need to remedy that quick because when I'm dead, the ole woman won't know crat about any of it, and it will all have been for nothing.  

I spent $150 more yesterday as I'll be losing the (glass) storm doors and replacing with the corrugated green house fiberglass.  I don't even remember what I spent on all the cpvc piping I bought in October to get the quadrants all put together. We had crappy weather and we took a week for a trip),  but I was able to assemble the 4 quads under my carport over a matter of 2 or 3 days.  Seems it always rains on my weekends.  Yesterday with the new fiberglass,  I bought two brass gate valves, (one for feeding unit #2 and one for return, and I SHOULD HAVE REPLACED THE OTHER two blue handled CPVC valves for unit 1 while I was doing this all over again, but didn't.  They have problems and I've learned that they don't hold up well.  One is by my storage tank under ground and feeds the water to this entire system.  It still works but not very well.  It is only about 1/4 open, and I don't dare touch it.  For now I let the two blues you see in the pic alone for they are CPVC and on the line IN to and OUT of unit 1. CORRECTION, ONE IS A RED HANDLED P.V.C. VALVE AND WILL BE REPLACED!  THE OTHER BLUE GOES TO UNIT # 1 AND WILL BE LEFT ALONE!  

I have all the plumbing hooked up back to the main feed location and ran out of elbows to get all the plumbing installed.  So I then decided to start stapling the "can coating" over my piping.  I wasn't sure how many cans I had preformed, but then about 3/4 of the way through with my supply of cans, my air compressor quit compressing.  Luckily, I didn't have many preformed cans left and finished what I had with a hand held stapler.  And as before (like Scott's original build), I used silicone under all the cans to bind to the pipe in hopes of helping the conduction of heat into the piping.  Pictures are attached of my progress. YESTERDAY was my birthday, so what better way to spend a BIRTHDAY, DOING what one pleases?  Enjoy all!

Went back and added an extra pic for a little clarity for my "main stack".  Both pipes in ground are Cpvc, so intent is taking the Red valved part out and replacing, but have to tie back into the feed and return of unit #1.RESIZE 1808.jpg  RESIZE 1809.jpg  RESIZE 1810.jpg  RESIZE 1811.jpg  RESIZE 1815.jpg  RESIZE 1816.jpg  RESIZE 1817.jpg  RESIZE 1818.jpg

Productive weekend.  Stapled my remaining cans, then needed about 150 more to finish the wrapping.  I got those cut, washed, and shaped and finished stapling all of them down today.  I then got the entire thing spray painted black.  I used some navy blue I had left to finish it off since I ran out of the black.  No photo available right now, I had to be somewhere right after dark.

Photos attached.  One shows the flow of my Unit #2.  Previous photos above do as well, as my step boards hide some of the plumbing.
ONE OTHER item of note, I will have a hose bib (faucet) in upper right quadrant's upper right corner into a tee there for a vent when I drain this unit.  You may or may not be able to see the tee there, but there's a female adapter there for a hose bibb.

Comments on photo 1, that perpendicular thing in far upper right corner of photo is (tongs, corn grabbers) I modified a bit to hold the cans firmly in place around the piping while I staple down the can covering.  

Photo 2 shows that it works pretty darn well, with the silicone under the cans and on top of the raw pipe, the cans grab well after the silicone dries and has held up under the heat as I could tell from my previous redo of unit one.  

The last photo depicts my can forming after I pull them out of my home-made wooden jig after just a few hits with a small ball pien hammer I used to shape them into workable form.

PS- I've got NO PROBLEM DRINKING AT ALL... (Midland)

It's a bit of an unconventional way of plumbing the 4 quadrants, I only say that because a plumber/heat pump tech once told me "water is lazy, it finds the easy way out". 

If you are getting hot water, it really doesn't matter, water must be getting into all your pipes.

You are correct on water takes easy route.  But I made it as hard as possible for the water to "take the e.z. route".  By the time it gets to the 4th upper left quadrant, it should be way hotter than other plans I have seen.  Thanks for your comments!

And sorry, one more Chris J, the water in any piping up in the top parts (and bottom parts) that are not being perfectly circulated are automatically RISING because heat goes "up" and so I think I'm getting full benefit out of all the piping in it the way it is.  If SOME WATER IS SLOWED DOWN while during the process, well to my common sense, that sounds like a PLUS! not a negative!  It all gets back to my insulated resevoir in the end.

Your right, makes complete sense, the longer the water is in there the hotter it gets.

THe first quad is plumbed similar to this as well.  After replacing the CpvC in that one, I DON"T seem to get as much heat because I didn't wrap the upper quadrants (3 & 4) with cans.  (counting from bottom left quad up the upper 4th quad).  The aluminum seems to transfer more heat to piping than just painting it black.

Will probably revisit, possibly recoat.  My controller (snap switch is in that unit, so I need a cloudy day, and not so darn cold.)  I've been under the weather since last Tues or Wednesday, spent Thurs at E.R. from 9:30 till 3:30. Broncosaurus-itis, broncitus, and COPD.  Gave me a breathing treatment, some steroid pills, A nebulizer and sent me home with a bunch of crap for breathing at home.  Hopeing to get back to work Monday, but I should have been resting today.  Been resting Thursday and Friday and just had to go out and DO SOMETHING!  Sunny and 64 ish.

I over did it today by cutting out and replacing half of the valving at entry and exit points to unit #1.  Two and half hours later I got Unit 1 all rejoined with new BRASS gate valves, pressured up with water, picked up my tools and all the pipe fittings and got my but in the house.  Well after dark, it's getting cool out to my 59 year old body.  Threw a couple of logs in wood stove, and now on here talking to you!

Hope to post pics at least of today's work tommorrow.  I didn't take any as it got dark at 6 as usual this time of year.  BRING ON DEC 21ST! ! !  PLEASE!!!

Thanks for views and comment!

Back to Chris from 10 days ago, I noticed when I pulled out the cold water piping on unit 2 (same if I remember correctly for unit 1), the middle sections of the PVC piping in the quadrants was about 20 to 25% more "pinker" than the risers on outer edges, which tells me more of the heat is getting through the middle sections of the quads then just up around the edges!  Then again, that's probably where most of the heat is being created at sun peak times during day.  Also looking at pics, I believe they are 8 ft (height) x 7 ft (width).  Just an FYI friend.  Thanks!
