Speaker BReady to turn your house into the home you've always dreamed of without the headaches or huge bills.
Speaker BYou're tuned to around the House, the nation's number one home improvement radio show and podcast with expert advice that's helped millions tackle everything from remodels to repairs.
Speaker BHosts Eric G. And John Dudley have got you covered with the best advice and information about your home.
Speaker BNow let's get this hour started.
Speaker AWelcome to the around the House show, your trusted source for everything about your home.
Speaker AThanks for joining us today.
Speaker AJohn Dudley, Good to see you, my friend.
Speaker CWhat's happening, brother?
Speaker AAlways fun on this one.
Speaker AWe have got one of the OG guests back on the show today, Ken Nelson, Panasonic Ventilation.
Speaker ABrother, good to see you again.
Speaker AIt's been a bit.
Speaker DIt's been a minute.
Speaker CYeah.
Speaker DI think it was one of the trade shows last year where we connected for a while.
Speaker AAbsolutely, man.
Speaker DAnd it's great.
Speaker AGeez.
Speaker ATrade show coming around here again soon.
Speaker AGet to see each other face to face, I'm sure.
Speaker ABut man, I have been using your products for sheesh.
Speaker AProbably I'm going to date myself, I'm going to say over 10 years and I'll just leave it at that because it's been a bit.
Speaker ABut there is still, in my opinion, nobody out there that is competing head to head with Panasonic Ventilation.
Speaker AAnd you guys are not paying me to say that.
Speaker AThis is just something that I've been using forever and no one's close, brother.
Speaker ASo great job that.
Speaker AStill, 10 years later, to not have anybody that's really doing what you guys are doing.
Speaker DWell, you know what?
Speaker DSo one of the things, one of the things I would like to talk about before our day is over is ervs.
Speaker DBut one of the primary pillars of ERVS is the motor.
Speaker DAnd if there's one thing that Panasonic does, we build motors.
Speaker DOur ecm, our electronic commutated motors, are so robust, in fact, in our fans.
Speaker DFor example, I have a fan in my crawl space that's been running straight for 18 years.
Speaker DI just use it in a crawl space to evacuate moisture load out of the crawl space.
Speaker DRight.
Speaker DContinuously moving air.
Speaker DI go down there about every five years and knock the dust out of the blower wheel and literally that's all I do.
Speaker DBut it is still running right now.
Speaker DI haven't looked at it the last couple minutes, but I can walk by one of my foundation vents and I can feel the air coming out of it.
Speaker DSo nice.
Speaker DWe build these robust motors.
Speaker DYou know, when you're a builder, one of the things you want is resilience in your products.
Speaker DRight.
Speaker DHoly cow.
Speaker DYou don't want to put something in and then be on that speed dial in three years.
Speaker DWhen you're a home buyer, your homeowner calls you up and say, yeah, this goofy little fan that you saved money on fails, and now I've got steam in my shower area.
Speaker DIt's just.
Speaker DIt's just too irritating to go cheap with that.
Speaker AYeah, yeah.
Speaker AI say this about your vent fans because you literally killed the business of mirror and medicine cabinet companies that were putting in heated mirrors and medicine cabinets.
Speaker AAnd I always just went, why do you need to buy that if you just got good ventilation?
Speaker DRight, Right.
Speaker DYep.
Speaker AIt's that simple.
Speaker DHave nothing to add to that.
Speaker DRight.
Speaker DI mean, ventilation.
Speaker DAnd ventilation is just really the key in that application.
Speaker DBut we want to remind everyone that ventilation doesn't just apply to the bathroom.
Speaker DRight.
Speaker DOne of the things we often forget is where moisture or water vapor is generated from within the house.
Speaker DRight.
Speaker DWe have a number of places as humans, we outgas moisture like crazy.
Speaker DWe have a kitchen where we cook and do all these other cleaning and projects.
Speaker DAnd then, of course, there's the bathroom where we dump high volumes of moisture in a short time into the house.
Speaker DSo ventilation, or bathroom ventilation, however you have that ventilation working, it solves all of those problems.
Speaker AIt does.
Speaker AAnd there's so many other rooms now getting added to this.
Speaker AAnd Johnny and I have talked a little bit about it in the past, and John, I'll let you jump in here in a second.
Speaker ABut nowadays I'm seeing all these new builds around my house.
Speaker AThey've got the three car garage.
Speaker AThey've insulated it, They've sheetrocked it.
Speaker AIt's beautiful.
Speaker AThey've got the glass, the frosted glass garage doors.
Speaker AAnd it looks like it's raining in there because they pull in in the wintertime.
Speaker AAbout right now.
Speaker AIt's 45 degrees outside.
Speaker AThe car is soaking wet.
Speaker ATwo cars pull in there.
Speaker AThey go inside, and all that moisture and the heat of the engine is sitting there in an insulated space.
Speaker AAnd I can guarantee you that every single storage tote of Christmas, Easter, whatever else is in there on sports equipment is a moldy, growing mess.
Speaker DHas become the chia pet of the garage.
Speaker DYeah.
Speaker AAnd it's something that unfortunately, building code really hasn't been addressing because technically it's not inside the structure, but it is.
Speaker AYou know what I mean?
Speaker DSo what we see is, we see the building code, which is basically the barely Legal house that you can build and the building code, that's your D.
Speaker AMinus and passenger class.
Speaker DYeah.
Speaker DAnd then you have above code program.
Speaker DSo if you built an Energy Star house, for example, in that attached garage, you would, to meet the Energy Star, the above code requirements of Energy Star be required to have some kind of an exhaust fan in there because it's not just moisture.
Speaker DRight.
Speaker DYou bring the car in there, you start it, you turn it off, it's out.
Speaker DGassing, Gosh.
Speaker DNitrogen dioxide, carbon monoxide, PM 2.5, everything you can associate with a combustion process, outgassing.
Speaker DAnd then of course, at my house, holy cow, you go out to my garage and my wife, she has her fertilizer, she has herbicides, I have pesticides, I'm bringing, I'm bringing the whole thing, the whole package into my garage and it's just separated by a self closing door.
Speaker DThat's it.
Speaker DYeah.
Speaker CPaints, solvents, everything else.
Speaker DExactly, exactly.
Speaker DDiesel.
Speaker DI've got diesel.
Speaker DI've got mixed fuel, I've got gasoline.
Speaker DHoly cow.
Speaker DOur garages are full of things that are not really the best things for us.
Speaker AYeah.
Speaker ASo Ken, in that kind of situation, is it better to put in a VIN fan or is that really where ERV should come in?
Speaker AOr what's your take on that?
Speaker ABecause code's not dealing with it.
Speaker DWhenever I talk to builders about that application, in my opinion, we have like one of the most perfect fans.
Speaker DWe have what we call our whisper sense fan.
Speaker DAnd what it is, it's a condensation sensor and a motion sensor all in one.
Speaker DAnd so you drive in, the fan's going to come on for an hour, or you can actually define that value.
Speaker DIt'd be 40 minutes, 30 minutes, whatever you wish, but it'll come on and evaporate and evacuate whatever's in there out.
Speaker DAnd then it's also got the moisture sensor.
Speaker DSo if you come in, we see this especially in our northern climates where the cars are as you described, they're wet or covered in snow, all that dribbles off.
Speaker DAnd now you've got your engine block or whatever heat source rising.
Speaker DI have shoe dryers in my garage.
Speaker DI have all sorts of stuff that's creating water vapor.
Speaker DAnd what I don't want it to do is adhere to a wall space so that fan will sense that moisture load and trigger on.
Speaker DProblem solved.
Speaker DRight.
Speaker DAnd again, part of our challenge is how do I make all of these functions so that the occupant doesn't have to go out and turn a switch on?
Speaker DRight.
Speaker DBecause the occupant won't.
Speaker DI mean, you might have a really savvy occupant that'll do it half the time or much of the time.
Speaker A100%.
Speaker AAnd it's the same thing in the bathroom.
Speaker AThat's the one nice thing about code, is that they've been putting timers and stuff in there.
Speaker AAnd as far as current code, they've gotten that better.
Speaker AAnd I want to say this because I did this at my, at my last house, I had another brand of fans that they said, hey, try this.
Speaker AAnother big brand.
Speaker AI'm not going to bash them here.
Speaker ABut it's in every builder basic house that you see out there.
Speaker AAnd it's been in those houses for 40 years.
Speaker AI turned it on for the first time and I just went, oh my gosh, this sounds no different.
Speaker AIt's their high end fan.
Speaker AIt sounds no different than the nasty $29 squirrel cage one that every low end builder puts in.
Speaker AAnd again, goes back to what you guys are doing.
Speaker AMy biggest complaint in 10 years of using those fans plus is the homeowner couldn't hear when it was on.
Speaker AOn a high ceiling.
Speaker AIs it even working?
Speaker AYeah, it's working.
Speaker CYeah.
Speaker DYeah, I know.
Speaker AJust because you can't hear it two rooms away doesn't mean it's not working right.
Speaker DExactly.
Speaker DAnd much to my chagrin, I'm like, they put Bluetooth.
Speaker DWe have a, we actually have a Bluetooth band now that will play the radio.
Speaker DCool.
Speaker DAnd I'm like, oh, my gosh, you guys.
Speaker DYou know, first of all, I already wrestle with builders based on cost and function and value.
Speaker DRight?
Speaker DBut a Bluetooth fan.
Speaker DAnd I love the idea of being able to put the speaker in the fan, but the reality is I got other ways to get music in my bathroom if I really want it.
Speaker DIt's just, you know, it just cracks me up.
Speaker DHow, how?
Speaker DVent fans.
Speaker DNow I will tell you that the lighting on fans has evolved.
Speaker DYeah, right.
Speaker DWe have, I've got color changing lights that you can change the temperature of the light, the brightness of the light.
Speaker DThey're all dimmable.
Speaker DThe LED lights are the.
Speaker DSome of the most robust.
Speaker DWhen I first started out in the industry 15 years ago, if you came to me and said, hey, should I put a lighted fan in?
Speaker DI would say, heck no.
Speaker BThe around the house show will be right back with more from Ken Nelson from Panasonic Ecosystems.
Speaker BWe are talking ventilation when we come back.
Speaker BThe kids these days will never understand.
Speaker AWhat it's like to play an instrument.
Speaker DWhat's up.
Speaker AThis is Sticks it Inia and Satchel from Steel Panther.
Speaker AAnd you are listening to around the.
Speaker BHouse with Eric G. Yeah, we love Eric G. And you should, too.
Speaker BWelcome back to the around the House show with Eric G And John Dudley.
Speaker BTo find out more about us, you can find us at our website, aroundthehouseonline.com.
Speaker Bnow let's get back with more from Ken Nelson from Panasonic Ecosystems.
Speaker DWhen I first started out in the industry 15 years ago, if you came to me and said, hey, should I put a lighted fan in?
Speaker DI would say, heck no, because I could put a thousand fans in and I would never get a phone call.
Speaker DYou put 10 lighted fans in, I would get at least a phone call.
Speaker DI mean, it was just.
Speaker DThey were so unreliable.
Speaker DBut now these new chipset, these new chipset LED lights, I swear to God, I've dropped them, I've kicked them across my shop floor, plug them in, boom.
Speaker DLook like it's here.
Speaker DSo lighting has really, really changed.
Speaker AI will say the Bluetooth has one useful place in the powder room that's right next to everybody that's having the party down there.
Speaker AYou can give the code to people to log in if they're not feeling well.
Speaker AAnd then if you want to Hijack it with YouTube sounds, you can do that when you're having the friends over, but play your own stuff while they're in there.
Speaker ABut you can.
Speaker DI gotta tell you, though, I always lean towards what's the best thing for the structure and the people that are there.
Speaker DRight.
Speaker DThe best thing for the structure is moisture management.
Speaker DThe best thing for people is indoor air quality.
Speaker DSo honestly, there's still place in there where music kind of comes into that mix.
Speaker ABut I'm a bit of a pure entertainment product.
Speaker CYeah, yeah.
Speaker DIf I'm going to spend money, I want to put it where the squeeze is the juicer worth the squeeze.
Speaker DRight.
Speaker ABut yeah, yeah, that's, that's.
Speaker DI don't want to deal with it.
Speaker DI'm just saying that.
Speaker DNot the best value.
Speaker AI like it, Ken.
Speaker DI like it.
Speaker AI want to talk.
Speaker AI mean, we've talked about kitchens and that stuff, but kitchens are so important in this whole mix of just good ventilation.
Speaker AAnd I'm not talking about just turning on that little tiny thing, the microwave.
Speaker ABecause the microwave is probably the worst ventilation product in the world for moving air.
Speaker DWhen you see those over the range.
Speaker AMicrowaves, as a designer, I refuse to put them in unless it was a must have in like a condo or something like that where you're like, okay, I'm stuck here.
Speaker AThis is the only thing.
Speaker ABut really having good ventilation in there really changes your indoor air quality just so quickly.
Speaker AIf you're cooking on that cooking service.
Speaker DRight, right.
Speaker DAnd again, one of the challenges in the kitchen is when you're cooking, you're not just vaporizing water, you're picking up things that are into the food groups that you're cooking, starches and whatnot.
Speaker DIf you think about in the way back when we were kids in school and you wanted to make glue, you used a starchy material and water and it would adhere, Right.
Speaker DSo if you vaporize that, put that into the air, all that does is find a surface to adhere to.
Speaker DAnd now that starch becomes food for mold and mildew.
Speaker DAnd literally that's the first step to having compromised breathing issues when you live in a unit that's had mold and mildew over and over, over again.
Speaker DI just, I remember we went into a weatherization project in Seattle and we went into a low income thing.
Speaker DAnd literally in the kitchen you could see where a picture frame was.
Speaker DRight.
Speaker DBecause it was white behind it and yellow all the way around.
Speaker DI mean, that's just material.
Speaker DIt's just material.
Speaker AIt is.
Speaker AAnd it's interesting.
Speaker AI really wish that there's another company you see in the home centers and it's the same one I was ripping on earlier.
Speaker AAnd I'm not going to use the name, but these recycled vent hoods, I wish that we would just ban them because we need to not have the.
Speaker AI call them forehead dusters because that's all they do.
Speaker AThey don't do anything.
Speaker AThey're worthless in my opinion.
Speaker DIt's the recirculation application and really all it tries to do is diffuse that moisture load throughout a wider space.
Speaker DQuicker.
Speaker DIt doesn't remove it, it just pushes it out farther and faster out into the space.
Speaker DYeah.
Speaker DIt's unfortunate, but there's a lot of them out there.
Speaker DIt's an annuity to Panasonic, to our ventilation team.
Speaker DThose are annuities because at some point they're going to have to figure out that that's a problem.
Speaker DAnd they'll put a fan in.
Speaker AYeah.
Speaker AAnd that's building code.
Speaker AI mean, that's here in where, where you live, Ken, up in Washington, where I live, down in Oregon and many states across the country, when you do that kitchen model, they require you to upgrade that ventilation and make it vent outside.
Speaker AAnd like in Oregon here, there are no working around that.
Speaker AIt's like that has to vent outside so gets a little interesting when you got condos and HOA boards and things like that, where you're like, hey, I got to drill a hole in the outside.
Speaker ABut it has to happen, you know.
Speaker DIn our climates here, our climates in Washington, Oregon, Idaho, honestly, pretty much the northern part of the US we do have.
Speaker DI think we have pretty darn good codes and code acceptance through inhalation.
Speaker DAnd part of that is because the cost of failure comes back to the building or the property manager.
Speaker DBut I do a lot of work in the South.
Speaker DTexas and Florida.
Speaker DFlorida and everything in between.
Speaker DAnd their codes are not nearly as.
Speaker DAs manageable there.
Speaker DRight.
Speaker DSo it's.
Speaker DIt's a different educational process to tell someone in the south about how to manage water vapor, how to manage moisture within the house when their humidity outside is far, far higher than the humidity inside.
Speaker DBut it can be done.
Speaker DBut it can be done, and it has to be done.
Speaker AYeah, it's smart.
Speaker AJohn, how many times did we tear into stuff and we see the vent fan that was venting into between the floors and the, you know, in the joist bays, or it went right up out of the kitchen, right into the attic space, and there's a plastic dryer vent laying across the insulation.
Speaker AThat's kind of just going to nowhere.
Speaker AThat's.
Speaker AThe other half of this.
Speaker DIs.
Speaker CIsn't that how you're supposed to install them?
Speaker CYou just throw the tube up in the attic and call it a day?
Speaker CIt'll.
Speaker CIt'll go out the sides on the, on the gable vents.
Speaker CRight.
Speaker DThat's fine, isn't it?
Speaker DThat is, if it's out of sight, it's not a problem.
Speaker DYeah.
Speaker DUntil science gets right, just right.
Speaker DI don't even want to put that out there.
Speaker DThat is inherent.
Speaker AEven if somebody wants to clip this up, let's make that very clear.
Speaker AThat has to go to the exterior of the building.
Speaker DRight.
Speaker CSo many problems in the Northwest.
Speaker DYeah.
Speaker AAnd it gets you.
Speaker AYou're right, though.
Speaker AAnd, Cam, we got a lot of stations in the south that listen to us down there.
Speaker AAnd so many times in building codes and areas, they go, hey, it's got a window.
Speaker AIt'll open up.
Speaker AThose people are not opening that up on a 95 degree day with 95% humidity.
Speaker ABut you still gotta get it out of there.
Speaker AAnd I think the biggest problem we see out there with building code builders, homeowners, is they think it's just a humidity issue.
Speaker ABut the humidity is just part of that.
Speaker AIt's the chemicals that you're using in the Bathroom.
Speaker AIt's the chemicals in the kitchen.
Speaker AYou need to get that stuff out of there.
Speaker AAnd I also want to say for all the.
Speaker AThere's certain people out there that I'll say are the.
Speaker AAre the gas range haters.
Speaker AWell, guess what?
Speaker AIf you cook on an induction cooktop, food that you're cooking, it is still putting off dangerous stuff.
Speaker ASo it is not just a gas combustion issue.
Speaker AYou're still putting out pretty bad air with a really high PM 2.5 that's still going out inside the room, no matter what surface you're cooking on.
Speaker DCombustion is another form of phase change, right?
Speaker DYou're going from one gas to a much smaller gas.
Speaker DJust like water.
Speaker DBoiling water is a phase change.
Speaker DYou go from liquid water to water vapor that you're changing that phase.
Speaker DAnd once it gets aerosolized, one of the things that we have to remember is as humans, you know what?
Speaker DI can swim in a dirty bathtub, but doggone it, if I have a dirty air and I breathe that in, that's passing all of my body's defenses into my body.
Speaker DAnd that's a problem, right?
Speaker BThe around the House show will be right back with more from Ken Nelson from Panasonic Ecosystems.
Speaker BWe are talking ventilation.
Speaker BWhen we come back, foreign.
Speaker BThe House show with Eric G. And John Dudley.
Speaker BTo find out more about us, you can find us at our website, around the House online dot com.
Speaker BNow let's get back with more from Ken Nelson from Panasonic Ecosystems.
Speaker BWe are talking ventilation.
Speaker DI wanted to touch base real quick on the opening the window idea.
Speaker DAnd while I love the.
Speaker DI love having an open window at my house, don't get me wrong, but keep in mind that you don't necessarily have ventilation with an open window.
Speaker DPeople forget in our natural physics that you have to have a pressure change from inside to outside for air to move.
Speaker DIt's when the wind blows, right?
Speaker DWhen the wind blows, you have higher pressure on one side, lower pressure on the other side.
Speaker DThe wind moves and tries to balance itself out.
Speaker DThe same thing has to happen in a house.
Speaker DI have to have a pressure difference in the house.
Speaker DWhether it's higher or lower, it doesn't matter.
Speaker DAnd move the air through the window opening.
Speaker DYou could have a window wide open and still not get ventilation.
Speaker DThe randomness of open windows, and I'll tell you that the way I always frame this, the builders and renovators and whatnot, is that mechanical ventilation should be, or all of ventilation should be predictable and uneventful.
Speaker DAnd that means I don't want to wait for the weather to change.
Speaker DI don't want to wait to have a temperature delta inside to outside, because warmer air is going to have higher pressure than cooler air.
Speaker DSo I want it predictable and uneventful.
Speaker DAnd that's why we use an exhaust fan.
Speaker DI mechanically draw air out, and air naturally comes in to fill the void.
Speaker AAnd many times, Ken, that air outside is way worse than the air inside.
Speaker DIt can be.
Speaker AThat's another issue.
Speaker ALook at fire season on the West Coast.
Speaker AWould we get wildfires out there?
Speaker AYou look at the.
Speaker AYou look at the.
Speaker AYou look at the air quality rating, you're like, wow, that's our area.
Speaker AOur air today in our area is worse than Beijing, China, on a bad day.
Speaker AOkay, maybe I don't want to open the window up and ventilate, because I better do something different.
Speaker DEric Panasoni has got this ongoing experiment going on in the south in Houston, Texas.
Speaker DWe literally built a house in Houston, Texas.
Speaker DAnd one of the reasons we chose Houston is because the outdoor air down there is uncomfortable, would be the nice way to say it.
Speaker DIt's often super hot and super humid.
Speaker DBut even more so in Houston, they have one of the highest PM2.5 load areas in the US and what happens is.
Speaker DAnd you and I will know how this works, because we live near the coastline.
Speaker DWe have an onshore flow, right, that comes off the coast.
Speaker DSo they're on the Gulf.
Speaker DAnd that onshore flow goes by all these petroleum plants where they're outgassing 2.5.
Speaker DAnd that onshore flow holds all of that particulate matter and drags it across the state going northward from south to north.
Speaker DAnd at about Houston or just beyond Houston is when it gets warm enough to vapor change and lift.
Speaker DSo in the meantime, you have low.
Speaker DYou have low air streams dragging PM 2.5.
Speaker DThey have obnoxious PM 2.5 particulates in that Houston market.
Speaker AYeah, that is so bad.
Speaker AAnd you're right.
Speaker AThat's a great place to sit there and do that testing, because, again, you get down in Texas and some of these other states, unfortunately, it can be the Wild west on some of this ventilation issues.
Speaker ASo, again, that's another place that's good to do the math, because I think that really tells a perfect story, because I've had homes that I've seen where they're right next to a beautiful wetland, but it's moldy, marshy mess out there, and that's all those mold spores are coming in.
Speaker AYou don't want to be opening the window up that day.
Speaker DRight, exactly.
Speaker DAnd let me tell you some of the findings that we're getting from this house.
Speaker DAnd be honest with you.
Speaker DWe built.
Speaker DWe had a custom home builder build this beautiful house, right?
Speaker DAnd soon as we took possession of it, our engineering teams moved in and started just pasting it with monitors and so forth.
Speaker DAnd we've had it running now.
Speaker DThe house has been running for a year.
Speaker DWe're monitoring all this stuff.
Speaker DAnd the builder is just, like, beside himself looking at us as we're putting monitors at, you know, three different levels in the vertical column, right?
Speaker DOn every room has at least nine monitors in it looking at different things, whether it's humidity, temperature, carbon dioxide, PM 2.5.
Speaker DBut there's so much stuff that we're finding, right?
Speaker DFirst of all, regarding ERVs.
Speaker DWe're running an ERV in there, and in the summertime, we're getting a 90% rejection of moisture running that supply air through the RV, meaning that if it's 80% humidity outside, I can put air in the house at 55% humidity.
Speaker DI mean, literally, we're.
Speaker DWe're.
Speaker DAnd what happens is.
Speaker DAnd I don't mean to go all sciency on everybody here, but the way ERBs work.
Speaker DYeah.
Speaker DThe two Airstreams pass, right?
Speaker DAnd I have a hot Airstream and a cool Airstream.
Speaker CHot.
Speaker DRemember I said hot has higher pressure than a cooler Airstream.
Speaker DAs they pass over the course of this membrane material, which is much like Gore Tex, only even smaller.
Speaker DAs it passes over, that hot material drives into the cooler, and all that goes right back outside.
Speaker DSo we wind up with a fraction of the moisture load in the house.
Speaker DSo now as the house.
Speaker DAs the function of the house, our dehumidifier, we put a dehumidifier in there, but it hardly ever runs, which is a big thing if you're building a house or you're owning a house in the south.
Speaker DBecause the dehumidifier is an expensive device to operate.
Speaker DI mean, it is.
Speaker ANow, let's.
Speaker AYeah, now let's talk about ERVs for a minute.
Speaker ASo let's.
Speaker ALet's.
Speaker AI know there's a lot of our audience out there going, erv, what are you talking about?
Speaker AOf course, Energy recovery ventilator.
Speaker AThese are required in new homes across the country and even remodels in places like Washington state and things like that now as well, for, of course, getting fresh air inside the house.
Speaker DSo let's.
Speaker ALet's dial this back for a second, Ken, and give them the 101 on that so people understand it okay, so.
Speaker DThe energy recovery ventilator or the erv, it goes back to that mechanical predictable airflow within your house.
Speaker DBecause what's happening today is that we all know that energy costs are skyrocketing everywhere.
Speaker DSo the builders are required to build a very good envelope.
Speaker DWhen we talk about the envelope of the house, it's where the house, all the heating and cooling is inside the envelope.
Speaker DWe want to keep this envelope nice and, and tight so it doesn't leak air in and out.
Speaker DMy, my old house that I live in has an air change leakage of about four and a half air changes per hour.
Speaker DMeaning that I have the potential for this 2,000 square foot house with nine foot ceiling.
Speaker DSo what is that?
Speaker DA 18,000 cubic feet of air to change every hour four and a half times.
Speaker DIt's obnoxious, right?
Speaker DSo we want to get a tighter house so I don't have to reheat all this air all the time.
Speaker DBut on the other hand, remember as I said, if there's no pressure difference, there's no reason for air to move one way or another.
Speaker DSo we would mechanically move it.
Speaker DWe have an ERV that is simply to describe the erv.
Speaker DIt's literally two fans in a box.
Speaker DOne fan drives air out, one fan drives air in.
Speaker DAnd as those two air streams pass, the heat energy from one airstream moves to the other.
Speaker DSo if it's cold outside and warm inside, that heat moves to that colder airstream and preheats that airstream coming in.
Speaker DBut if it's obnoxiously hot outside heating that airstream, the heat moves into the other airstream and is sent back out.
Speaker DSo I can keep the house cool or warm at the cost of running.
Speaker DTwo exhaust stands, right?
Speaker DNo heating or cooling required.
Speaker DThe erv from, from a economy standpoint, if you're running in a climate where you have moisture loads, where you have cooling required or heating required, the ERV is as a mainstay for that heating and cooling system, or should be, because now it also pulls any of that moisture load.
Speaker DThe other thing that you can do with the ERV is because you're mechanically bringing in supplier, we put a MERV 13 filter on there.
Speaker DSo now again, when we're in Houston and that high loads of PM2.5, while we recommend that you check your filter every 90 days, that filter, we change that every 30 days and it's just black when we replace it.
Speaker DBecause what happens there, hot, humid, picks up the mold, the pollens and so forth, that sticks into that filter rather than bringing it into the house.
Speaker DBut it only takes three days for that to turn into again your giant chia pet, your black chia pet, where it's just nasty.
Speaker ASo, Ken, have they got a technology wise yet?
Speaker AAnd I don't know this answer, but it's something that I've been asking for a lot of years.
Speaker AHave they gotten to a point now where that could actually shut off if the outdoor air is so poor?
Speaker BLike, not all of this episode will end up on the radio show, so.
Speaker BSo make sure you catch the entire show on your favorite podcast player.
Speaker BThe around the House show will be right back with more from Ken Nelson from Panasonic Ecosystems.
Speaker BWe are talking ventilation when we come back.
Speaker DAll right.
Speaker BWelcome back to the around the House show with Eric G. And John Dudley.
Speaker BTo find out more about us, you can find us at our website, aroundthehouse online.com.
Speaker Bnot all of this episode will end up on the radio show, so make sure you catch the entire show on your favorite podcast player.
Speaker BNow let's get back with more from Ken Nelson from Panasonic Ecosystems.
Speaker DFair assessment of what will have the best impact, not just the biggest, but the best impact on your house.
Speaker AAbsolutely.
Speaker AAnd Ken and John, this is something since you've gone to Columbia scene, but nowadays in Seattle or anywhere in Washington state, if you dive into a significant kitchen remodel or remodel inside the house, they are saying, hey, by the way, while you're at it, that ERV has to go in on that.
Speaker AAnd so that's something that we're seeing kind of racing across the country as far as what we're seeing with that.
Speaker AAnd I think it's really important for us to have that conversation because it's going to be in everybody's backyard.
Speaker ANow, when you go into projects that state by state is building, science gets smarter.
Speaker AAnd we know what we need to require.
Speaker AKen, you guys are doing so much with ERVs out there.
Speaker AThis isn't that 1980s weird box in the ceiling in the laundry room with a bunch of rubber bands in it.
Speaker AThere's a lot of science going into this.
Speaker DThere is, there's.
Speaker DAnd you know what?
Speaker DHere's the thing.
Speaker DThe science, science is so simple, but the reality is simple is the most complex thing.
Speaker DRight?
Speaker DPeople always talk about, well, I want to, I want the easy button.
Speaker DBut the work that goes behind creating the easy button to make things happen is, is quite remarkable.
Speaker DSo we want more energy transfer out of the erv, I want to save more energy or I want to reject heat energy or I want to reject moisture outside or save moisture inside.
Speaker DHow can the ERV do all this super effectively?
Speaker DAnd, and there's ways to do it bit I also can't raise your price.
Speaker DI don't want to raise your price.
Speaker DI want this to be done with.
Speaker DYou know, I talk about price, cost and value.
Speaker DI need to keep the price and the cost down by it, but enhance the value.
Speaker DSo the four pillars, we kind of alluded to the motor being one of the primary pillars of ERVs.
Speaker DNumber two would be the core.
Speaker DExcuse me, I'm going to jump around.
Speaker DBut 1 is the motor, 2 is configuration, 3 is the core and 4 is filter, right?
Speaker DBecause I want the core.
Speaker DAnd honestly with an ERV, the core is 2/3 the cost of the ERV.
Speaker DBecause that material that allows that water vapor to go through there is just not something you can pull out of your kitchen, kitchen drawer and create it.
Speaker DRight.
Speaker DIt's, it's, it's a piece of membrane that has been stretched, flexed and it has very precise permission permeable material that's, that allows water vapor to pass through.
Speaker DSo the core is, is quite unique.
Speaker DAnd there's two types of cores.
Speaker DThere's this cross flow core where the air passes left and passes right and that's where the material goes.
Speaker DAnd then there's this transflow core where the air comes in and then it's turned to go a straight line and then it's turned again to exit it.
Speaker DAnd what happens is to make the ERV more efficient, we have to add more pressure inside that core.
Speaker DEach of those turn enhances that pressure in that airstream.
Speaker DSo it's going to move from one stream to the next.
Speaker DIt's literally, it gives us two, excuse me, gives us 90% efficient on those cores.
Speaker DYou know what, that core is more expensive.
Speaker DIf that doesn't work, we have lower cost cores, lower cost ERVs.
Speaker DBut the reality is if you live in a cold climate and heating is expensive, or you live in a hot wet climate and heat cooling is expensive, those more efficient cores will far, far save you more money in the long run than the couple, you know, the 50 to 20 bucks that you're going to save on a, on a lower priced product.
Speaker DSo, and then the filter, because just because, just because we live in a world has wildfires in here in the northwest we see moisture loads down in the south, you go to Alaska and they have mosquitoes for heaven's sakes.
Speaker DThe filters are super critical and I have to make a device that will take a filter that's not going to set us all back.
Speaker DSo we're.
Speaker DWe're working really hard to work on those four pillars of the ERV to make them more affordable but more effective.
Speaker DAnd that's.
Speaker DIf you go to when.
Speaker DWhen you come to the kitchen and bath show.
Speaker DThat's one of the things we're going to talk.
Speaker DWe're going to talk about how we're making ERVs more efficient, more affordable, better configurations for builders, quieter, the whole package.
Speaker AYeah, that makes sense, Ken.
Speaker AAnd I think that's one of the things, too, that people.
Speaker ANew homeowners especially, and it's something that even the longtime contractors like Johnny here, you got to remember to change that filter.
Speaker AThere's enough filters around.
Speaker AYou got your refrigerator filter, you got all these filters.
Speaker ABut that ERV filter, you better stay on top of that because at some point it's going to be like that.
Speaker AI always, I always call it.
Speaker AIt's like that, that cabin air filter in your car that you forget about until it's not working and you go, oh, you didn't change that.
Speaker ABut it's a key piece to maintain.
Speaker DRight.
Speaker CAnd that's why life is simpler in Colombia, because we don't even have bath fans here.
Speaker CSo there's no filter changing going on.
Speaker DYeah, your windows are open.
Speaker DI stayed in a place they didn't even have windows, they had slats.
Speaker DIt was a beautiful thing.
Speaker DYep.
Speaker DYeah.
Speaker ABut I gotta give Johnny a hard time here because he also has no hot water going to the shower.
Speaker AAnd they have this heater that's sitting there that's a point of use water heater with wire nuts that are hanging in the shower, and that's common there.
Speaker ASo you've got a 110 wire that's open with wire nuts in your shower.
Speaker AIt's not even in a box.
Speaker CSo it's fine.
Speaker CIt's fine.
Speaker CBut here's right.
Speaker CSo today I was helping Miguel's sister move and her little daughter wanted to play the game on my phone, Right.
Speaker CAnd the phone was plugged in and her mom slipped out.
Speaker CI know.
Speaker CNot while the phone's plugged in, but we have shower heads with bare wires.
Speaker CGet in there, kids.
Speaker CLike it's a self that's not going to get it.
Speaker CYeah, yeah.
Speaker AThat maintenance stuff, that you could have the best stuff in the world, but if you don't maintain it, it's not going to stay up to date for you and it's not going to work as designed.
Speaker CYeah.
Speaker DOr it's going to work opposite of design.
Speaker AYeah, yeah.
Speaker AEven worse.
Speaker AEven worse.
Speaker AI tell you what, Ken, it is always fun to have you on here, brother.
Speaker AAnd I can't wait to see a face to face here in a few weeks down at the design and construction week in Orlando, where we're all having to fly across country to go do that.
Speaker AAnd that's going to be a lot of fun to hang out with you down there and take a look and see and touch and feel.
Speaker AThe latest stuff from Panasonic is down there.
Speaker DBeautiful, man.
Speaker DI can't wait to have you come by.
Speaker DWe'll go and monkey with all the buttons and play with all the.
Speaker DAll the toys.
Speaker AI will be monkeying with it for sure.
Speaker ASo, Johnny, we're going to have to get you up next year for that.
Speaker CWell, I was just going to say I might get up there for that or.
Speaker CYou do realize how close Florida is to fly over to Columbia, if you guys wanted to just come and visit for a spell.
Speaker AYou're not wrong, bro.
Speaker CI am not wrong right now.
Speaker AI got a thing, though.
Speaker AI'm staying out of that Venezuelan airspace right now.
Speaker ASo I'm just gonna have to stay away from you, brother.
Speaker CYeah, yeah, yeah, yeah.
Speaker CYou're gonna want to sail around that point, really keep a wide breeze.
Speaker DI would probably take my chances with the airspace more so than the ocean space below it.
Speaker CYeah, for sure.
Speaker AI'm not going out in a fishing boat, let's put it that way.
Speaker DFour motors.
Speaker DYeah.
Speaker CThat's no more unsafe than taking a shower here.
Speaker CWe don't worry about it.
Speaker AWay to bring it around.
Speaker ASo, Ken, how do people find you guys?
Speaker AI mean, you guys are in, of course, for builders and remodelers.
Speaker AYou're out everywhere out there, but you're not always in, like, the home improvement storage.
Speaker ABut I think it's something that if even a homeowner is doing a DIY project and they just need to put a fan in, they need to be using your stuff instead of.
Speaker AInstead of others because it just works so much better.
Speaker AAnd you're one of those.
Speaker AThere's not a lot of companies out there that I can say there's no competition to, really, as far as quality and what they get.
Speaker AAnd you guys are kind of one of those rare ones, man.
Speaker DWell, I'll tell you.
Speaker DSo finding us has gotten way, way easier.
Speaker DWe are now in most of the home improvement stores.
Speaker DNice.
Speaker DWe're at wholesale distribution.
Speaker DIf you're doing more design work, you'll see us.
Speaker DAnd again, at some of the higher end wholesale distributions, where they do mechanical design and so forth.
Speaker DThe vent fan industry before 20 years ago was literally like the light bulb industry.
Speaker DYou had to go to a special place to get a special light bulb.
Speaker DBut today I've got product just about anywhere.
Speaker DAnd you can certainly go to our webpage and Eric, I'll send you some links to some videos that we've done and I'll capture your material and put it out on our Panasonic LinkedIn and Facebook and all that as well.
Speaker DSo some shared knowledge opportunities.
Speaker AMan, I love it.
Speaker AI love it.
Speaker AAnd you guys are just continuing to innovate and I love that you're doing, doing it.
Speaker AAnd Ken, thanks for coming on, man.
Speaker AAnd I will see you in a few weeks.
Speaker AI'm looking forward to that.
Speaker DYes, sir.
Speaker CI just want to throw in.
Speaker CI wanted to throw it in at the beginning, Eric, when you said 10 years plus, you've been using these products.
Speaker CI will tell you that as a contractor in the early 2000s with Kevin working with me.
Speaker DRight.
Speaker CWe used to have to special order or go to someplace special to get, which was definitely a bit of an upsell.
Speaker CBut we, that there was no competition for the Panasonic fans back then.
Speaker DRight.
Speaker CAnd it was just.
Speaker CYeah, no different, same thing.
Speaker BRight.
Speaker CEven back then you're talking about 25 years ago and people still were saying, is it on?
Speaker CIs it on?
Speaker CLike that's how, that's how long you guys have been great.
Speaker CAnd again, you're not paying me to say that.
Speaker CThat's just reality.
Speaker CIt's, it's been the best for 20 plus years.
Speaker CYeah.
Speaker DI just remember taking fans into the distribution and saying, these are going to be three times more than the ones you have in stock.
Speaker DBut listen to this.
Speaker DAnd there would be nothing but silence.
Speaker DAnd they would still mock me, say, oh, people regular buy those.
Speaker DAnd I'm like, what?
Speaker DJust bring them in.
Speaker DI'll go make all this happen.
Speaker DAnd now our fan business is a 200 million dollar juggernaut that we couldn't be more proud of.
Speaker CYeah.
Speaker CAnd well it should be.
Speaker DYeah, absolutely.
Speaker AAll right, let's wrap a bow around this one.
Speaker AKen, thanks for coming on today.
Speaker AJohn, great to see you.
Speaker DI appreciate you having me on and I look forward to seeing you guys at the builder show.
Speaker AAll right, sounds good.
Speaker AI'm Eric G. You've been listening to around the House.
