"Thank you, Dennis. I can benefit from your experience. I was considering the plywood to evenly distribute, glad to hear experienced others have had the same impulse. "
"Thank you, Mick. Very helpful. Definitely leaning towards EPS or XPS at this point."
"Thank you, Sean."
I am about to install a 50-gallon Rheem heat pump water heater in our garage at our house near Pasadena, CA. (after this installation, our home will be all-electric. yay!)I watched Bruce Manclark's and Wade Cohn's excellent how-to installation video…
"Sorry this is happening, Brennan. Sounds like you're set on an unvented assembly (i.e., no air gap, soffit and ridge vents)? If it's the issue Ed is describing, maybe 1" polyiso continuous across the rafters could keep them from cooling from the…"
"@Leo Wow it sounds like you have quite the PV array. Can't quite discern, but sounds like you're close to (or at?) ZNE? As for the 76 kWh/month, I feel the same way when I read that the average US household consumes over 22,000 kWh a year: how is…"

1. Cost of PV array was about $15k before 30% federal tax credit.
2. The financial payback for our system is not very compelling right now. Our utility bills gas + electricity averaged less than $30/month before we did anything on the…"

Hey thanks! Yeah, it's time for an update on the energy consumption now that I've installed the mini-split but have yet to completely air seal the house. Let's just say that there's been some rebound effect. :) I'm jealous of your area's…"

"@Grey re: estimated vs. actual production
Good question! The estimated first-year annual production was 5654 kWh, actual production was 5413 kWh."

"Seems like high velocity and low noise are at odds with each other. And one of the biggest impediments to people using range hoods in their homes is noise. Wouldn't requiring higher velocity exacerbate this problem? Sorry forgive my ignorance but…"
"Thanks for the rundown, Jim. Sounds like some good stuff."
"@Lloyd -- Yeah, we can't wait either! :) Thanks for reading. We'll provide an update once we've done the after-renovation blower door test. The test-in number was about 3400 cfm50, (~18 ACH50). Lots of room for improvement."
"Hi Chris,
Thanks again for your help. Update: the system is now up and running.

"Chris,
A million thanks! This is very helpful; thank you for sharing your expertise. I can post an update once I'm further along. I am tempted to ask more questions but will not abuse your generosity. :) Happy New Year to you as well!

Hello!I'm installing a two-zone Mitsubishi mini split (in Pasadena, CA area, 1400 sf, single family detached, one-story home, if context is relevant). This is my first install, and I am trying to determine if extra refrigerant needs to be added…
