Insulation is good BUT polyisocyanurate foam board, that you have used,, degrades over time releaseing cyanide gas, yep! I recommend extruded styrofoam (blueboard) for your application
@water4fuelh20 Thank you I very much like making these videos and I appreciate your comment. Music seems to pull the videos together,,, Pu8t the sun on your team...
I think polyester is your personal best idea as far as water, but 50f outside input air temp and a collector temp of only 135F stagnant is a very weak collector ,looks like it would run around 52F at outdoor freezing temps..probably less with more thermal loss thru the glazing and metal frame @ those temperatures. .
@CheapEnergyIdeas Thanks for the comment. I like your handle... I thank your are right. polyester would probably exchange more heat in a water environment. but I do believe this concept could be developed and it is cheap...
hi
can anyone translate this video to greek?

Well done. How is that polyester felt working out for you?

@xtomkx ... Thank you.. I love working with polyester felt. It seems to last forever. It works best for hot water systems.

@CTOL1 Thank you I have estimate that the heat exchange efficiency for this design is about 35%
