menaus2's 240sqft Hydronic Thermal collector

The world slows down, but construction continues! Framing has been completed. The shed wall isn't exactly plumb, but it's level. Good enough! I siliconed (black silicone) the wood to keep moisture out on back side. Next is the 1" polyiso board (staggered). Then pine 3/4"x 1.5"s to finish the glazing support. Glazing support is set back 1/2" to allow the polycarbonate to be siliconed on the outside. I put 2" strips of polyiso on the inside edge of the frame to finish up the insulation. Currently working on putting up the 1/2" OSB panels over the polyiso. All the piping/ collector fins will be eventually stapled to the OSB.

The underground insulated pex I got is the reflexive bubble wrap inside of drain tile style. Some online sources point out they can lose a ton of heat if water gets into the pipe. Does anyone have experience with wood boiler pipe like this? I was thinking I might install sock drain tile pipe beneath it just incase the pipe ever got punctured to keep it dry enough. Possibly a drain hole at the low point of the underground boiler pipe just to give the water an escape route in case water ever did get in?
