Mfg. home, block skirt insulation

I am setting a 25x65 mfg home on a full slab foundation in zone 5+, high desert Cascades. I will be putting in a 3 course cement block "skirt" with mechanical ventilation. I am considering installing 2" rigid foam panels 24"x48" attached to the inside of the block skirt. I am looking for heat retention in the winter primarily (-20 on occasion). Will this be worth the effort and expense??

Vintage radiant gas heater

Can a vintage radiant gas heater be installed in place of a where a fake fireplace once was ? There is a vent pipe sill in tact . If so is the existing vent sufficient or should an exhaust fan also be installed?

Polyiso along slab edge

There was a picture in the latest Finehomebuilding magazine of a wall profile of a newly built house. I'm going to try and attach it below. It shows polyiso foam along the slab edge of the basement. They used xps under the slab. I thought that because it can absorb moisture, polyiso shouldn't be used anywhere but above grade. From the picture it is positioned right on top of the footing along the slab edge. Is that ok?

Ground gutter/curtain drain techniques

I have a 1920s home in Columbus, OH. As is typical of the neighborhood, it's a small footprint (~800 sf) and more vertically oriented (finished space on 4 floors). The house has an existing gutter system, but the west wall (picture attached) still receives water exposure during heavy rainfall. We have an interior french drain system that functions - water will come through the weep holes during heavy rain, but there has not been water infiltration on other parts of the wall.

Bathroom ceiling and walls

Working on a project in Quebec. It’s an older home and we are remodeling in steps. We rebuilt one wall of the house, leveled and rebuilt a sub floor in this area. This process required us to tear out the bathroom and two closets on each side of the bathroom. This entire section of the house appears to be an add-on at some point in time and the roofline over this section runs at a slightly lower pitch than the main roof. The ceiling in this area is treated as a cathedral type since the rafters hit the top plate at around 6 feet.

Does surface wiring on exterior walls make sense with batt insulation?

I've read a lot about the difficulties of properly installing batt insulation. If I kept my plumbing out of exterior walls, and used surface wiring on exterior walls, would that greatly simplify installing rock wool batt insulation? Or, would there still be other obstacles?

If surface wiring would improve the performance of batt insulation, other than the purported aesthetic issues with surface wiring, is there any other reason to oppose its use?

What are good thermal break details on things like hose bibs, gas meters, and exterior lighting penetrations?

In PERSIST/REMOTE wall construction with 4 to 6 inches of rigid foam outside the sheathing, furring strips over the foam, and siding attached to the furring strips, what are good ways to handle things like water pipe for faucets, natural gas supply lines, and metal electrical conduit penetrations? I don't know how to provide a good thermal break consistent with mechanically strong (metal) piping, solidly attached to the structure, exposed to the elements on the exterior that punches right through to conditioned space on the other.

Dare to DIY a mini split install?

Hi all,
Can editors step out from behind the curtain to ask opinions, too? I'm planning to redo my garage shop this Fall and although my primary heat for the space is a woodstove, I'd love to have some supplemental heating, and cooling in the summer would be great, too. I'm no schlep when it comes to remodeling work, but have never installed or seen a mini split install. Would I be a fool to try the install myself or have the kits gotten streamlined to the point that its basically plug and play, complete with factory-charged units and quick connect line sets, etc?
