Can't decide what would be the best method. #1. I could place a large mounting board on my garage wall and add sides and make it a box with a cover or have it exposed, having the 24 pex hoses coming out the top then curving up into the attic thru the drywall. Or #2 remove the drywall on that wall, mount the Manabloc in between the studs and drill holes in the studs and top sill for the tubing to go through. re-drywall and add access panel to Manabloc. I would like option #2 the best as it would be very clean looking but i worry about drill 24 holes, 12 in each stub bay in the top sill plates on a load bearing wall. Trying to decide which way to submit it on my permit. What do you guys think?
