Off the wall heating idea
I don’t know if anything like this would work, but im kicking around the idea so hear goes.
My pool is only a 15’ x 52”, small backyard , round aboveground , the pump is a Hayward 2 speed ¾hp. with a 150lb. sand filter .
With a new roof just installed on my home I really didn’t want to put solar panels on the roof, so I thought why not go inside ,the attic ceiling was over 140 degrees this summer .
I was thinking of running 2” pvc from the return on the sand filter to a valve , so the water could be diverted directly to the pool or to my idea. Going around the pool under the deck to the side of the house ,up the wall 12 feet then into the attic, at that point a “ manifold “ taking the 2” into four ½ inch lines, ( aluminum would have the least resistance to heat)
Going between the roof beams (22” on mine) attach the panels to the ceiling ,they would be approximately 20” x 48” and each one would have around 120 feet of pipe ( 30 coils up and down) then all four lines coming together into another manifold to 2” pvc back down the wall to the pool. When it gets to cold attach an air hose to a coupler and blow all the water out of the lines.
To take this one step further, why couldn’t you run over to the homes heater ( mine is gas) going inside the heaters exhaust vent tube , most of these are only 8” so might go ahead and change to a 16” then put a coil in this , you are heating your home anyway and all that heat is just wasted .
Just some food for thought, like to hear some thought on this, booster pumps needed ,etc.
