What Should I Use? - Ventilation

[@samuelhainey1466]

Jake spoke to some great principles. Many exhaust vents such as cook stoves can be set up with conditioned or unconditioned make-up air delivered in proximity to the exhaust vent source. Even if make-up air is not conditioned, it's exhausted at the vent. Vents that need make-up air can be set up, similar to HRV. Hot cook stove air conditions cold make-up air coming in during the summer. During the summer, the warm make- air is just vented out. KEEP UP THE GREAT EDUCATION CONTENT JAKE AND MATT!

Lol, I think I've already got the water design settled for our eventual build. Dual parallel multistage whole house filters to get all of the water up to a pretty good quality but not extremely pure, then a RO system in the utility room hooked up to a third water line that runs to the bathrooms, kitchen, refrigerator, and wet bar for the extremely good water where I want it. Not exactly cheap, though.

From what i’ve experimented with, the fresh air intake only brings in as much as is lost when supplied to the systems return air duct, and if you do that you should have the system running the fan continuously. That 8” pipe has the ability to bring in 300cfm at 100’ at .1” static but its unlikely its going to blast 300cfm out of all the weatherstripping and recepticals, however you would have enough air to replace all the air when your running the bathroom fans, dryer and kitchen fan all at the same time

Thank you for the information! I'm now curious, and will be looking into the differences between this premium ERV and premium ERV offerings, hoping to someday replace my two mediocre 80% efficiency ERVs that my HVAC contractor unfortunately chose and installed for me.

Thanks Jake. I hope the arm, shoulder, elbow, or whatever injury you are mending gets healed up soon. It is nice to see some other high-quality ERV other than Zehnder. Not that I mind seeing that particular product; it just makes me feel that the US doesn't understand air, and maybe we do not understand air as well as our European cousins. I know you and your Team at the Build show frown upon woodburning fireplaces, but is there a double damper system? One with a damper at the top of the firebox and one at the top of the chimney stack? That would seem to me to maybe be a decent solution to the problem. It would maybe create a static column of air that could keep leakage at a minimum. Would you need a makeup air supply if you do have a traditional chimney? I mean you do want the house to be slightly pressurized so as to not back draft the chimney and pull smoke into the house.

All I know after 27 years of home ownership, and the past 6 years of making my house better and an HRV install is this. There is no perfection. CO2, Radon, off gassing, wildfire smoke. Try to control it all, and you go down a rabbit hole. Now making things better, great. But not everyday will be the same in your house. After awhile., you just say, good enough, and move on

[@andreycham4797]

The purpose of ventilation is to remove excessive CO2 from a house. Another thing could be important you do not want to lose money in process, so we need some sort of hrv. Other than these, it is less important

[@virgil3241]

@@andreycham4797 So Co2 is the only thing. Something that in theory isnt that big of a deal, yet to hell with Radon? Im 52, and for the first time in 27 years of home ownership. and the first time Ive ever owned a CO2 detector for levels. And the previous decades of my life not knowing my levels, and guess what? Nothing, thats what. Life moved on. I get we all want clean fresh air., control humidity, get rid of smells, etc. But its almost the point of the sky is falling if your house ever creeps up past 1000 ppm, like we will keel over and die. But fear sells

[@bobnomura2068]

About the water - I would install, without question, whole-house filtration plus water softener plus a RO unit for the kitchen sink. The ERV makes a lot of sense, didn't know they existed until I started watching the Build Series. Makes total sense, my next new construction home (with some help from a future lotto win) will have all that in wildfire and hard water prone SoCal. Along with ICF walls, etc.

[@CMCraftsman]

Jake, we spoke at JLC last year about my house and the mold problems and things I had going on, and last week I was finally able to get the duct guys to come run the ducting in my basement to my Broan Ai hrv and although I know I should have gotten an ERV, I’m pleased to finally see the humidity in my house that used to be 65 70% at times drop to 45% and no more condensation on the window in our bedroom in the morning. I do have a bath fan though, I’m curious if my hrv feels that change and adjusts for the extra exhaust being that it’s self balancing unit?

[@nolanbillings8426]

I’m no expert but from my research the broan ai look will not self adjust to pressure imbalances in the home. It just adjusts the fans to make sure they are flowing the same cfm based on the different duct work attached to the ERV.

[@ts4009]

Jake Curious what a little "supply" pressure is when creating a small amount of continuous supply pressure. Is a "little" 1 pa, 3pa, ???

[@williampope4712]

THANK YOU!

[@jamesbarlow6243]

Question about over-ventilation with ERVs. We are adding an ERV system to a larger sqft home, and our MPE won’t include all of the bathrooms because he’s worried about over ventilating the house? I understand the desire not to waste conditioned air, but wouldn’t an on-demand unit or boost function allow exhaust ventilation of dirty air from all the bathrooms/kitchen areas? I just suspect we chose this MPE company poorly….

[@scottfarland6795]

What concerns are there with "condensing" of the outdoor air with the more humid indoor air even allowing for the built in heater?

[@LindaWallace-o7q]

Thank you so much for this amazing video! I have a quick question: My OKX wallet holds some USDT, and I have the seed phrase. (alarm fetch churn bridge exercise tape speak race clerk couch crater letter). How should I go about transferring them to Binance?

[@greenis3006]

All this talk about the flair and zero mention of where to get the ventilation distribution boxes, tubing, etc etc......... please make a follow up video on that

Zhender and Brink are higher end ones

Renewaire for a good performance/dollar ratio.

[@CybekCusal]

Kids, don't connect your kitchen hood to an ERV. It is full of grease and will destroy the ERV. This is incorrect.

[@475.SUPPLY]

Great clarification. Brink ERV continuous exhaust will remove smells and be suitable for most cooking. The Brink kitchen exhaust grill includes changeable filter to protect the system. However, the Brink should never be used as a make-up air system for powerful kitchen hoods.

[@peli3783]

Remember in our teen years we just watched to party and now we are watching videos of a man who partied too hard and broke his arm speaking about water

[@jimr4566]

Pretty much a commercial for a single ERV supplier.

[@OrthopedicRegenerativeMedicine]

sorry... lots of blabbing ......

[@OrthopedicRegenerativeMedicine]

and remember make up air is not conditioned in any way... makeup does not go through the ERV... it is air from outside...

[@475.SUPPLY]

Correct. The Brink FLAIR HRV and ERVs create a balanced system. Bathroom exhaust requirements can be met through the ERV (eliminating the need for exhaust only fans). This exhaust is balanced through supplies to the sleeping / living spaces (therefore no negative pressure is created and no make-up air is required). However, for very powerful kitchen hoods you will need a self-modulating make-up air system (MUAS) with self-closing dampers to balance out exhausted air… and possibly a make-up air heater (MUAH) for comfort.
