Long-time lurker, first-time poster.
I'm finishing the upstairs of my cape-style home. It will be about 1,700 sq-ft when finished. I have all of my heat registers sweated with PEX fittings and they are installed on the walls. I'm planning on running the Ox Barrier PEX tubing inside of the side attic knee walls. I'm concerned about:
1. Freezing
2. Lowering the water temperature. This is a 225' zone.
What is the best way to insulate & protect the tubing? I could run the PEX along the top of the floor joists (2x10) which are fully insulated and then place R-19 batts above the PEX. I've also been thinking about running PVC conduit along the wall/joist intersection and sealing the conduit with expanding foam.
Is there an accepted practice in this type of installation?
