Why a bath fan if you have an ERV? I would think you have to add makeup air with how tight your build is. Typically, you tie the bathrooms together to the ERV so it continuously pulls humid stinky air out of them.
The answer for my situation is a little complicated - tying bath fans to ERV exhaust is certainly an option. However, the geometry of my framing, existing plumbing, and utility room layout prevented easily connecting the upstairs fan to the ERV exhaust. I also didn't want to share any air pathways between upstairs and downstairs (even with a backdraft damper), so I also didn't want to connect the shop bath fan the ERV. Framing and mechanical obstacles also made it much easier to pop it through the wall. I consulted with Broan who we are using for all the IAQ equipment and their recommendation for my situation was also to use direct-vented bath fans to simplify ERV ducting and optimize effectiveness. More to come on HVAC and IAQ equipment integration
@MasonDixonAcres look forward to seeing that. I am going with broan as well for me erv, but since I designed my house, I made sure to account for all plumbing and hvac runs within the walls.
What kind of hole saw are you using that it doesn’t grab and try to rip your arm off?? That’s what it seems like every time I use my Milwaukee HoleDozers…

I’m looking everywhere for that exterior junction box you used for the receptacles but can’t find it. What is it called? Thanks. You said it’s 41cu in and cost $25.
Your work is so detailed, you can tell that your not a mood butcher like some of the so called “builders” awesome work

Heads up. That ladder angle is fairly dangerous.
When I had it set near the deck ledger it definitely was 😅
That was going to be my comment as well. 70 degrees is what we use in the fire service.

You have a tight house. I can't see any air, water, or bugs getting through any of those penetrations.
Gotta have that continuous air barrier 👌🏼 And not pictured is the air sealing around the ducts and wires as they exit the wall.. future video
You’re skeptical re whether ERV+boost will work, and that’s why the bath fan? Anecdotal reports do seem to be divided.

Why didn’t you use any exterior insulation
For your outdoor receptacle blocking, fixtures, etc. what material did you use? Can it be made from anything or does it have to be pvc?
It can be made of any typical exterior material (wood, pvc, fiber cement, etc.) as long as you have a UL junction box containing the wires

It's a Ply Gem product, I got it through my local HD

@@MasonDixonAcres Greatly appreciated
Don’t know if I’d enjoy sitting on that deck with all the fart fans exhausting right next to it.
Haha you'd really have to be blowing up that bathroom to notice anything
what type of materail did you use to make you 10x10 picture frame for your erv exhaust?
PVC trim board 👍🏼
