Nothing has been built yet. Im not using pressure treated wood for my floor deck. my piers will be pt posts on top of concrete. I do already have 2 truck loads of pt 4 x 4 posts gratis. Non pt 2 x 12 on 24" centers come out to about $ 500 locally. I also have 30 sheets Recycled 3/4" cdx. And personally i prefer a crawlspace for plumbing, wiring, and maintenance. I could pour a thin concrete floor with tubing on top of my subfloor if the gains are there. Being in a mostly cooling environment id hate to go crazy with the heating if a less involved heating solution will suffice.
At what water temp are you heating yout floors with? Is any ony solar wayer heating their floor?
