I’m not going all-electric on this transform, however I really feel inspired in regards to the function of minisplits and the concept of minimizing pure fuel utilization, for all the explanations Chad defined. I significantly appreciated that Patrick and Chad of their dialog:

I’m within the last levels of my small woodshop transform. I stay in rural Kandiyohi County in Minnesota which is firmly within the higher 6A zone and I additionally had a earlier 20×24 ft indifferent storage that I needed to warmth. One drawback you aren’t contemplating with heating a wooden store is flamable wooden mud. The issue with most heating techniques is what to do with a dusty atmosphere. Even with actually good mud assortment there’s nonetheless loads of high quality mud. So, what I made a decision to do was make a radiant hydronic ceiling. I’ll connect the article I discovered that helped me lay all the pieces out. I used fundamental double-paned vinyl home windows and patio door, fundamental metal door, and a r21 storage door. I insulated the ground with r7.5 xps foam and subfloor, r13 2×4 with r5 xps foam on inside, and r60+blown in cellulose. Above the hydronic strains I used the reflectx bubble inferred insulation taped seams in every single place. This winter it was an excellent 70 levels utilizing a 7kw electrical boiler set to 105-degree water temp whereas it was -20 outdoors. It finally ends up including about $30 a month to my electrical invoice this winter. I feel my modeled warmth load was round 7000btu/hr @ -30/75-degree f.

Query 1: How tight is just too tight when transforming my 196os colonial?


Kyle writes: Hey guys from FHB, I simply seen your base is out of Newtown, CT. Very long time Monroe resident and now at present in Woodbury!! I simply discovered you guys and have been listening to the podcast nonstop: I’ve discovered the previous few have been really humorous but additionally tremendous informative given I’ve been within the HVAC (principally propane/oil heating) business for nearly 10 years. The generator electrician was nearly spot on, and ductwork guys actually are hit and miss with workmanship. Just a bit again story:

My fiancé and I purchased our first home a couple of 12 months and a 1/2 in the past in CT zone 6. Our home is a typical late 60s colonial authentic siding and home windows. We’re redoing it slowly however certainly. I used to be torn between siding choices and new home windows and doorways given they’re authentic single pane. Given the age, electrical, and plumbing we’re slowly rehabbing the entire home. It’s 2×4 building and I used to be pondering vinyl with exterior insulation however I hate Vinyl. So, we opted out. We determined with do all of the work to take away outdoors siding +sheathing and go together with the zip R-9, zip tape, Anderson 400 2×6 home windows and new rock wool R-15. With this improve to 2×6 depth and have total r-24 insulation.

Now there’s loads of speak between moisture barrier/air limitations moisture/air permission, rain screens. New constructing strategies, inexperienced constructing strategies and old style let it breathe. I’m curious on how tight is just too tight and what could possibly be greatest for an previous to new rehab. Will I must plastic wrap behind sheet rock or will the wall paint be sufficient to seal?

• I don’t wanna be trapping any moisture however I wanna cease air from leaking in to create that lifeless house from condensation.
I’m additionally inquisitive about my attic scenario.
• I’d love to interchange roof in subsequent few years and go metallic.
• Ought to I spray foam attic and soffits to get a extra tight home and envelope the within or go away it unconditioned? (Given I’ve a hydro setup in attic)

There are such a lot of completely different theories on the subject I simply don’t wanna overdo it and on the flip aspect I wanna maintain as a lot warmth as doable inside the home with out having so as to add supplemental air. We already modified from an all-electric baseboard to boiler with hydro air basement/first and second-floor break up zoned system and radiant underfloor system on first as a result of entry in basement. Should you guys wanna put this over podcast or electronic mail and even name I’d love to speak it appears your group is fairly effectively versed in these areas. It’s onerous to discover a inexperienced residence group or respected contractor to speak out these choices with out paying them… haha. I’ll submit some photos with this additionally to indicate progress and work completed and what’s occurring. Should you guys want a propane technician or heating man, I’m free to talk additionally.

So, we purchased in August of 2020 proper earlier than the market shot by means of the roof with the NYC motion out throughout covid! It was a financial institution owned home that wanted all the pieces redone. The earlier 12 months the home was listed for $180k didn’t promote, after we regarded it was once more listed for $180k. Having been by means of 4-5 different comparable home gives we knew if we needed it understanding market values, we provided $230k and had 2 matching gives. So, we settled at $245k.

Since then full heating system/with central air, including standby generator, gutting of a moldy 70s typical completed basement system, small full bathtub on the primary flooring have all been up to date. So far as finances we’re lucky sufficient to each be working and we will absolutely perceive the justification of value for what we get. WHEN I HEARD BATHROOM ESTIMATES OF 70k!!!!!! We did ours with tiled flooring, bathe, glass package and fiberglass pan for underneath 5k!!! (Full intestine and subfloor substitute)
With us doing all of the work now we have saved a TON so a $# for finances kinda an unknown. We simply deal with initiatives as they arrive up.
I do know your gonna say you must discover a quantity and keep on with a finances. However our realtor stopped by and stated in present 1/2-way transformed state… Our home might be listed at $400k or extra due to the market… So, something we do will come again in return hahaha.

Carson from Oregon writes: Hello FHB crew, Thanks for the nice podcast! I heard episode 438 and it made me suppose what the equal stick framing methodology could be and the way it would possibly examine to concrete printing. Do you suppose modular building in factories could be the wood framing equal, and the way do you see it evaluating? What’s the present cutting-edge, when does this make sense, and may anybody purchase these? I’ve seen Bensonwood earlier than, however that appears to principally contain individuals nonetheless framing by hand. A google search turned up Autovol, which seems extra like fashionable automotive manufacturing however with residence modules.

It’s superb to a non-expert that automation and manufacturing hasn’t taken over the business prefer it has so many others, particularly to somebody operating into loads of labor/talent shortages on a delayed venture.
