comment Vertical direction of thermal expansion tank
One consideration is that it is easier to remove a failed tank that is full of water when the threaded port is point up. If the port is pointing down, water will spill out while removing it (though I don't have personal experience from this).

comment Adding ventilation and insulation with limited soffits
Ideally, there would be a rafter baffle and soffit venting in every rafter bay, to prevent the roof deck from getting too warm (and melting snow, which could lead to ice damming).

comment Solar panels and batteries as primary, grid as backup with auto transfer switch
I don't know about an auto transfer switch, but I know people (in NM) who've done PV+batteries with a manual switch to grid for backup: thegoodlifelab.com/2008/11/video-pv-solar-off-grid.html

comment Hot water heating system: Renew or replace?
"Forced air, by its nature dries out the air" It is a commonly held belief that forced air heat dries out the air more than radiant heat, but it is actually a myth. See: bookstore.ashrae.biz/journal/download.php?file=ASHRAE-D-AJ11MarHVAC-20110305.pdf

"...dramatically changing the humidity." It is a myth that forced air heat dries out the air more than radiant heat. See: bookstore.ashrae.biz/journal/…

comment Is transitioning to all electric heating smart?
@HenryJackson. Good point! I hadn't thought about that.

comment Is transitioning to all electric heating smart?
The oil boiler uses electricity for pumps and possibly draft fan and ignition. Most gas furnaces require electricity as well. Electricity outages are not really a good argument against going all-electric.

comment What is the downside to installing faced fiberglass insulation in a dirt floor crawlspace vs non-faced?
@ojait, yes, putting the rigid foam below the fiberglass is a good solution if you really need a vented crawlspace. The foam is a much better vapor retarder than the paper facing. Nice diagrams and discussion of that and other solutions here: buildingscience.com/documents/insights/…

comment What is the downside to installing faced fiberglass insulation in a dirt floor crawlspace vs non-faced?
@DavidC, I'm not talking about a concrete rat pad. I'm talking sealing the vents and insulating the crawlspace walls instead of the crawlspace ceiling. You could use fiberglass, rock wool, rigid foam, or spray foam (in order of increasing cost), but regardless, an unvented crawlspace will be drier and have fewer moisture issues

comment Clickey clackey bathroom exhaust louver
It is one big flap—you can see the bottom of it in the photo. If you want one that has no potential for clickey clackey, try these: conservationmart.com/…. You'd still need some sort of mesh to keep critters out.

comment Getting R38 in roof with 2x8 rafters
Wouldn't the roof dry to the inside? What climate are you in? You may need more than R-10 in foam to keep the vapor retarder (inside face of foam) warm. See: greenbuildingadvisor.com/blogs/dept/musings/…
