If using ductless spot ERV's (Pioneer Ecoasis 150) in combination with mini-split heating/cooling systems, would you put the ERV near or far away from the mini-split interior unit? Comment from : @abeloewy5458

Would love a video on Brink ERV Comment from : @imjusthereforlolz

Just used some in a small rental suite build There i was not able to fit a ducted system Expensive but only decent available option and fullfills the task Comment from : @patrickcowan8701

It's the best available solutions when retrofitting a house without a loft Comment from : @AceMcMoron

Sooo, what the heck is the solution for an erv? I have a 450sq ft studio and bought one of those 30 cfm ductless erv units Comment from : @lowfrequencyfilms

All your videos are very informative! I had a glimpse of hope and a sense of validation when you mentioned DIY HRV video A lot of people who suffered from mold and toxins cannot afford purchasing ERV or HRV, it would be very beneficial if you could guide about doing DIY ERV or HRV Thank you for all the work you've done You save many lives Comment from : @khaofangsakolsupa138

ERV or HRV for Montreal? brbrWe get Hugh humid summers with temperatures in the mid 80’s to low 90s and 70-90 humiditybrbrWinter is cold, very cold Up to minus 8 Global warming gives us frozen rain storms which we never hadbrbrI have a basic static HRV I hate it I want to upgrade to an auto-balancing unit brbrSo, ERV or HRV? Which brand? Thanks Comment from : @FirstLast-et3sw

Hello,brFirst of all poor audio and video qualitybrI’m a complete begginer, dont know much about home ventilation, and you are talking Cfm, erv, spot exhaust etc… using phrases which is very confusingbrFor you it may be very clear, but not everyone is as familiar with this subject as youbrPoor quality and confusing video, for a begginer I wouldn’t recommend watching you, for an advanced user I’m sure you give very useful information Comment from : @mtauta

I'm getting a feeling that I can DIY a regenerative ERV system appropriately sized for a single room for about $200 in parts But it will be a year before I'll have that room built to try it out on It will be interesting to see what sort of efficiency that I can get out of it I just don't understand why these units are so expensive Comment from : @richdobbs6595

Do you have any recommendations for a tiny home that is already finished, but doesnt have any ventilation system Its just two rooms and no kitchen or shower Comment from : @nathanellison594

Hi Thanks for your videos Super helpful I am thinking of installing a Cyclone SV130 in the lower level of my house to help with air quality This is purportedly an ERV The information that accompanies this product is not terribly helpful What I'm trying to figure out is whether these should be purchased in pairs or if I could start with one and go from there? Any information or advice you can provide about this product would be highly appreciated Comment from : @as17ns22

Your channel is a gold mine of information in my recent quest to replace my broken Venmar Constructo 20, Thank you very much Comment from : @jacobmarley2417

Thanks for the video, but I would like to add some Eurpean context: for example in Italy we rarely have air ducted homes, also our houses are made from bricks with width between 20-40 inches There these spot ERV are a good compromise for recycling the air and reducing the humidity in some rooms Comment from : @ploughable

meanwhile bosch has a similar product but they literally made it impossible to buy 😢 Comment from : @zzzaaalll

panasonic in the title but I think you didn't go into it much? since this video came out panasonic released a newer model, the FV-06VE1, which is slightly larger and has more features than the FV-04VE1 (ability to adjust balancing/modes) I think it might be the best retrofit option currently I have seen it for $488 online, which makes things like the Lunos look super expensive for an inferior option Comment from : @jefferylebowski7355

Hey @HomePerformance, I have a question regarding the corrugated plastic HRV design, and what you'd think about thatbrFirstly instead of making air go sideways, I'd make it countercurrent - half channels go directly out, half go directly in While doing that, I would also elongate the heat exchange unit to get more gradientbrSecondly, removing unnecessary half of those plastic boards to lower thickness of material heat has to pass through - make them just flat channels with some separators for constant widthbrThirdly - possibly installing a wick that would transfer moisture from one side to another - this would however only work if dew point was reached on one side, so yeahbrTo remove recirculation, I'd create narrow outlet (both sides) that would speed up air to shoot it out a little further I would use centrifugal fans to get necessary pressure for thatbrbrDo you think this is feasable or not even worth trying?brWe have more of a cold climate here, rather than super hot, so preserving heat is most important objective here Comment from : @michahalczuk9071

6:47 - Alex canned his DIY HRV because it made the air quality in his house worse and ended up buying an ERV & Dehumidifier So the DIY option is really limited to non-humid climatesbrbrWhat I really wish anyone would explain is what exact materials and parts are different between HRVs and ERVs (not the outcome) Comment from : @Casperankinen

Will they work to remove window condensation in winter? That’s all I care about Comment from : @somedude5353

Ductless would be great for a small cabin in the woods that is extremely airtight Comment from : @leonscott543

I’m renovating and extending my home in the UK and want to install a system to change the air in the house, but due to ceilings height, cannot fit a ducted system What are my options if not the decentralised units? Comment from : @wilyc0y0te

Your mic is on point! I’m gonna applaud you for that You got like ASMR podcast thing going on Comment from : @oemca1919

Thanks for the overview! Those switching Lunos fans seem like junk for the price! On the Ephoca systems, a couple of comments: br#1: For the short cycling intake vs exhaust, intuitively I would agree that this could be an issue However it seems like this is just your word vs theirs Or did you smoke test it to see if it short cycles? br#2: Just because it is an all-in-one solution does not mean it is inherently bad It really depends on the application For a tiny home or ADU, these are pretty great! On a project I am working on we are only required 30cfm of ventilation air By using the unit for ventilation, we get rid of the need for additional exterior louver, 15-20ft of GSM duct, soffiting and supply register Time and materials for this completely justifies the additional cost of the internal ERV It is for sure limited to small homes or ADUs because it can only achieve 40cfm Comment from : @NicoChiarito

Why is Zehnder out of favor with you? Comment from : @generalbystander1631

I agree they are not so good value for the money compared to the ducted ones They are convenient for small retrofit projects though , a lot of European apartments were built without ducting in mind, my own included I have installed a pair of those in my 2 room flat and they definitely work, admittedly not even close to a ducted system Comment from : @curiousmind1991

Do not be afraid Do not be worried The reason why these type systems worry you or make you uncomfortable is you are not as familiar with the newer technology as you are with the typical mini split type systems brVrf, erv ,ductless have been around since the 80s That equipment is obsolete And so is the equipment you are recommending to your customers You Just don’t know it yetMitsubishi lg Samsung and all the other major names that have been around for over 30 years and although yes they offer a hyper heat solutions that heats with low temps and negative temps it has taken them 3 decades to get to this point Units are still bulky and same design and when they came out brWith no outdoor unit to install no lineset no communication wiring less noise than any typical split system on the market why you got to be hating ? The more you know the less worried you will be brAnd in 5-10 years you will be laughing at the options you were recommended to you clients brLet go of the Dinosaur age technology / equipment and embrace the newbrbr ephocacom/company/#history Comment from : @JanesR-n9v

I thought spot erv were for a bathroom or a kitchen And you get a big duct type erv for whole house I am planning on a hrv too I need a "vent to daylight" because of masonry floor area I plan on having a south wall planter So plan on hanging it above the planter Comment from : @eliinthewolverinestate6729

Thank you!!! I live in an old house and I was trying to get better air quality and run into this products I was like I need it! But I had the same question how I am sure they don’t feeds in the stale air if ducts are next to each other What are the options for a retrofit house Comment from : @eymimi

How do these things deal with condensation? They don't seem tilted to let gravity drain out the water They look installed perfectly perpendicular to the wall Comment from : @caustinolino3687

Thanks for the videobrbrI’m buying a 1300 sq ft, 2 level home in the Yucatán, MexicobrbrI want to 1) be able to ‘turn over’ the air in the house so I don’t have to keep windows, etc, open And, 2) demumidify the air since this is the tropics The house will also have mini splits for cooling and 3) I would want to filter the incoming air for allergens/pollensbrbrCan you give me an idea at what I might want to look at?brbrMany thanksbrbr😎 🇲🇽 Comment from : @Lane9693

What do you think of the optional fresh air intake for Santa Fe Ultra dehumidifiers? They lack the energy saving feature of ERVs but if already needing a dehumidifier they can dehumidify fresh air that is brought in through a merv 13 filter, and in the winter can run on fan only mode to keep bringing in fresh filtered air Of course they cost more than a broan or panasonic ERV so wouldn't make sense if not already needing a dehumidifier, and they could also pair well together, or pair a Santa Fe with a DIY HRV Comment from : @NurseAcrobat

This is a good video and I’d be interested to see a smoke test done considering how close the inlet and outlet is Comment from : @jimmythetech

Thanks for your video I am currently building a tiny house with 300 sqft / 2 people living in it in the Northwest / Idaho What ERV system would you recommend installing? Thank you Comment from : @catharinamoritz7454

Many people can't use ductless system due to old brick building, concrete block building without attic space (specialty in warmer climate like south america, india and africa) house usually have a split system there for cooling would greatly appreciate your recommendation for places like this? Any particular system & brand you would choose overalls Comment from : @whatever_12

Wow from England! I was looking at the Lunos E2 and found your video really interesting You see we live in a granite longhouse in the middle of a damp National Park called Dartmoor We are in the process of insulating the house and have an airsource heat pump which works great in the part of the house that is insulated However even before the insulation we had a humidity, and therefore a mould, issue and I'm concerned that with sealing us in, the problem will get worse We are not going for passive house standards but need to reduce the humidity without reducing temperature (due to the lower temperature radiators with the heat pump) - which is why we were looking at Lunos This is a retro fit to a 700 year old house; so there's no way we can use ducting But if these spot MVHR units have issues is there anything you would recommend as we don't want cold air blowing in but we need to remove humidity OR would you say for our situation these could be OK Please can you help - Steve Comment from : @bellabutler48

Sorry I might have missed this but what was your conclusion on the best way to filter and exchange air and humidity without having a system with ductwork? Comment from : @drewhenriques1359

I fail to see how a pair of inlet/outlet fans alternately switching provide any sort of heat recovery as there is no exchanger? Comment from : @JC-jv5xw

Why would you want to install an ERV/HRV in the bathroom?????? Comment from : @st3ppenwolf

Hi Corbett, thanks for the vids as always! You said at about 2m20s regarding Zehnder that you "don't recommend for other reasons" Are you able to elaborate on the reason(s), other than price? It would be a great help to those of us looking to buy a Zehnder I'm happy to be steered in another direction Cheers Comment from : @AL-tv7wo

Hey Corbett Remember me? I bought 32 lunos fans for my project! The bath fan was always an issue in my case - I specced fan timers to mitigate pressure issues - but the more pressing concern is adequate dilution air since we are about 20 ACH We are giving each homeowner an Aranet-4 Co2 sensor to help them figure out how high to run the Lunos system Looking forward to sharing if the system can keep up with the occupants Comment from : @connorgarrett7064

What if ducting is not an option? What options do you recommend? Comment from : @withsandylam

Would have liked to see you do more research about the Lunos before claiming it doesn’t recover humidity More research would have enlightened you to the fact that the e2-60 adjusts to pressure imbalance so theoretically the bathroom exhaust add-on would work I installed these in my house because we couldn’t run ducting and they are working very well Not an ERV but better than nothing brAgain, maybe a bit more research since people are coming to you for expert advice You even described the lunos components wrong :( Comment from : @evanpierce564

You just missed discussing the ceramic element on the lumos… did you had this pruduct in your hand? No otherwise you would talk about it Comment from : @pasternakel

I appreciate this video and validates some of my suspicions about the efficacy of these units What is a better option for retrofitting an ERV? I have a new builder-grade home that is very tight and the air quality in the kitchen literally stinks I considered a spot ERV like this because the only way I can install a ducted ERV is by running insulted lines through my unconditioned attic (I've heard this is a no-no) Comment from : @youngrq87

Regarding Tiny homes and IAQ, is the issue more outgassing from the building materials or from the humans and activities (cooking, etc)?brI remembered you used plywood that did not contain formaldehyde for the indoor walls on the Tiny Lab Comment from : @DavGreg

I'm installing a pair of Lunos e2-60 HRVs in the small house I'm building I was leery of a ducted system since I have an unconditioned attic and having a ducted ERV up there would be utterly pointless in the summer due to the extreme attic temperatures A through-the-wall system has at least a fighting chance (I hope)brbrRegarding creating an unbalanced system -- I emailed Lunos support on that topic with regards to using them as makeup air for a range hood The claim is that the Lunos detects when the airflow is counter to the fan direction and will shut off the fan in those cases Thus, it is literally just two (filtered) holes in the wall at that point and should be able to pull as much air as necessary We'll see Comment from : @granworks

Corbin, would like to discuss when convenientbrI am a Building Official, Licensed Energy Advisor and Certified Passive House Consultant with some experience and testing background on thesebrWould like to to talk and geek out Comment from : @wgamborski

Thanks Corbett for the amazing video Comment from : @arjungupta-inventor-iaq

When we look back 50 years or so and look at how construction and HVAC was done we laugh It would be interesting to be able to know what our future selves will think about our current methods of construction and HVAC Hopefully that we got it right but more than likely they will laugh and say I can’t believe they thought this or that was a good idea Comment from : @trickstothetrades1801

Interesting, a real buyer beware and informed situation Comment from : @markn2904

There is a brand here that sells a mini erv similar to those However by the time you fit one for every room the cost is horrendous Comment from : @tweake7175

Thanks so much Corbett! I really appreciate you discussing my DIY HRV Not only that, but this video was full of invaluable information on which systems to avoid Love it, as usual Comment from : @HealthyHomeGuide

Do any ERV's filter up to HEPA level? Comment from : @alexanderjamieson7971

The Lunos can recover moisture in cold weather when the incoming air is below the dewpoint of the outgoing air Moisture in the outgoing air condenses on the core as it warms, the evaporates into the dry incoming air as it cools I don’t believe it’s as efficient as an ERV, but it’s much better than nothing (a la HRV)brbrRegarding balancing, if you put a pair in the same air space you don’t have to worry about pressure zones messing with balanced airflow, but this gets spendy real fast depending on how many zones you need ventilatedbrbrI agree with all the negatives, especially price If designing a house from scratch there’s no excuse to use these over a ducted system Comment from : @superspeeder

I think the Build Equinox CERV2 looks awesome I’d buy it if I had $6,700 Comment from : @davidhoover2446

Look at the power requirements I believe they're 220V as it is European Comment from : @mennomateo

Are you talking about the Hyper Heat H2i? It goes down to -13°F I wish they had a version for cold climates that worked down to -25°F or colder Comment from : @MarkRose1337

I gave Alex a follow I'll watch his video shortly Comment from : @MarkRose1337

You would think they'd have a bath fan that integrated with their two piece HRV to provide balanced ventilation Comment from : @MarkRose1337

Have you been involved in any projects using the CERV2 from BuildEquinox? Comment from : @raptormatt21

Re zhender-aside from the obvious-price- and inability to imbalance delie establish positive pressure, and as you have demonstrated, non negative pressures in the house as it’s impossible to generate really high pressures in American homes/del any other issue you ha with zhender? Thanks Comment from : @johnwhite2576

So I am understanding correctly, there aren't really any recommended solutions for retrofitting in a home without ducts? ERV/HRV or otherwise? Comment from : @Obtuse94
