Does radiant heat recycle water

With regular radiant heating systems that use warm/hot water to run through tubes in the floor to heat the home, what happens to this water - does it get recycled through the system, heated up again, or does it go down a drain?

Detail for stone veneer

I am looking for a wall framing detail that includes a stone veneer face over 1" ridged insulation. It seems to me that after a rain screen detail over the rigid, the next surface would be OSB or plywood that metal lath would be adhered for applying the stone veneer? So the assembly would be 2x6 stud wall, OSB, WRB, 1" ridged insulation, rain screen (lath, Coravent, etc), 1/2" plywood, metal lath, stone veneer.

ICF & window areas WITHOUT wood bucks

I observed an ICF build that did NOT use wood window bucks for the window areas. They used some temporary wood shoring but once the shoring was removed the window area was all raw concrete and ICF/EPS foam. The windows will be installed directly into the concrete using concrete screws and window brackets. The windows will be installed halfway in the window area or otherwise known as an "innie" window.

Super insulating and soundproofing

I'm curious as to whether anyone has integrated soundproofing techniques into superinsulated walls. As mentioned in other posts, I'm considering adding thickness to my existing walls in the form of rigid foam, without removing current drywall. I hear foam is not the best for sound, although at least the 3/4" airspace and second layer of drywall will help. I'm curious if anyone else has explored trying to get the best of both worlds, R-value and sound reduction, while keeping thickness to a minimum.

Home energy monitoring programs

I am building a net zero energy home to Passive House standards in the Seattle area. In addition to having it be as efficient as possible, my goals were to use renewable materials (no foam), eliminate thermal bridging. have a protected air-barrier and to keep the OSB warm. I'm using dense packed cellulose in the R-50 walls and R-85 roof (cathedral ceiling with parallel chord trusses). The wall assembly is a double stud system with an inner 2x6 load bearing wall and an outer 2x4 wall.

Proper wall to attach rigid foam to the inside of the wall?

Question: what is the best way to attach rigid foam (foil faced polyiso) board to the inside of a finished wall? Can I just use longer drywall screws to go through the 1" foam and existing drywall? What if I'm going with more than that (say 2 or 3 inches of polyiso)? I'm worried that this method would have a greater tendency to pop the drywall screws out under small impacts like hanging a picture. I'm also worried that the walls will sound hollow or be bouncy when knocking on them. What are the best practices for each thickness of foam?

Choosing Insulation for a Cathedral Ceiling

This is my situation: I am located in colorado, where is is generally dry, gets hot in the summer and cold in the winter. I am in process of building my own house and want to make choices that wont come back to bite me down the road. With that in mind I want to avoid any moisture issues inside my ceiling cavities. What I have so far is a stick framed cathedral ceiling using 2x12 dimensional lumber. On top of the rafters I installed 1/2" CDX sheathing and covered that with grace tri-flex (I wish I had used felt paper).

Plumbing vents exiting ridge cap

Can't seem to find anything in the code, easily missed though. I have a customer who wants a metal roof installed however they have had bad experiences with pipe flashings through the roof and don't like the look of them. While I don't care for the pipe boots, (for metal roofing), appearance they seem to work well.

Anyway, to the question... Is there anything code or common sense wise that says vents couldn't go through the ridge cap? I know it wouldn't look as good but, would limit water flowing over them.
