Im no HVAC genius but I have been building and using panasonic fans, icf's, advantech sheathing since my first house in the 90's. Panasonic makes some really good HVAC stuff but I feel like they are missing the mark with this ERV. Since they already have a full line of some of the best exhaust fans why not build in some type of control cables (such as an ethernet cable port on each fan and ERV) that would connect and network the bath/kitchen exhaust fans throughout the house to the ERV. So when the ERV recieved a signal from one of the exhaust fans being turned on it would automatically ramp up the incoming air stream to help balance the interior pressure and provide filtered and conditioned makeup air for the exhaust fan. Not only would it solve multiple issues for the builder/consumer but would help sell more equipment on Panasonic's end since most people would then choose to go go panasonic for everything throughout the house. There's no shortage of choices in ERV's in the marketplace but No one has anything like a fully connected/networked system that senses when to boost fan speed based on the needs of the home. Not that I know of anyways.
This comment hits it out of the park. I have been trying to address this need for a while, with my new build spec home there is 3 bath fans and the house threw a 2.8 ACH50 for the blower door. I'm looking for an erv that will automatically sense the pressure imbalance in the house and supply make up air when called for to keep the house close to neutral. Does anyone at all know of a system that can achieve this?
Agree that would be a nice feature. But a simple solution -- instead run the intake ducts for the ERV to all the bathrooms (ditch the typical bath fan) and use a standard wall timer switch in each bthroom to turn on the ERV. I'll tie into the input for 24V on the ERV that typically would be connected to furnace thermostat/fan. You can either use 24V to the bath timer wall switch or, as I plan to do, the wall timer will simply turn on the 110V to a 24V transformer that sits in the utility room with the ERV. Now to figure out if I can mount this ERV on the wall vertically instead of horizontally.
The latest version of the Panasonic FV-10VE2 has a "boost" function, a wired "boost" switch input to the unit. When the "boost" switch closes, it forces the ERV SA to 100 Cfm and EA to 100 Cfm for as long as your "boost" switch timer is on.
If you exhaust the bathrooms through the ERV, and each one has its own "boost" switch, just wire the "boost" switches in parallel to the ERV, so any bath can demand high speed ERV operation. If your range hood Isn't heavy on the Cfms, you might let it "boost" the ERV as well, however there is a code for that, so be sure to read that first.
Love the inwall steel stringer in the background. Ready for some floating treads!!!
Brian Gio yes sir! Good eye!
Way to give North Dakota a shout out. Use your channel to give me ideas if I ever build a house. As an engineer I love the efficiency you go after.
Chad Kuntz thanks Chad!
Very impressive
Matt Risinger, I was in a meeting today talking about this model thinking that I had scooped everyone on the latest and greatest from Panasonic....until Anthony Cox told me that you put out this video last week. Nice work.
Thanks Matt for all the videos. I just completed the framing of a 720 sq. ft room addition in San Antonio using some of the best practice methods from your videos (advanced vs. traditional framing). Also, using the Tyvek products for house wrapping and flashing a flanged window. Anyhow, I'm installing a Mitsubishi mini split in this room addition and was wondering if I would benefit from using the Panasonic ERV. I'm not sure if this space would be too small for a unit this size? The 2x6 walls will have foam as well as the 2x8 roof rafters. Windows and doors have double pane Low E366 glass. I tried to make the room as tight as possible and now am thinking that I might need to bring fresh air in?
Very cool
I've always wondered if any ERV system can work with dehumidifier together.
Hello, great job, what is the size of the extraction pipes for the baths and insufflation of the rooms?
A key point because it used to confuse me, an ERV does not actually dehumidify air, and may not take much moisture out at all. Drying still needs to be done with dehumidification.
For example, Corbett Lunsford on his TinyLab tour had an HRV core in and was struggling with high humidity in the house. He changed it to an ERV core and couldn't detect a measurable difference, despite having several dataloggers in the house.
For what it's worth, I've become a convert of pressurization and whole house ventilating dehumidifiers, which I know you've reviewed at other times. I'm tracking a few installs, we'll see how it works out.
It depends on when you want to do the drying, Nate. Drying via ventilation is pretty effective when it's dry outside, in the winter.
There's a fairly large difference in moisture transfer rates for different ERV cores (and at different cfm rates). At the HVI rated summer condition, this unit has a moisture transfer rate of 56%. Amazingly, the HVI specs show an 80% moisture transfer rate at the lowest rated airflow of 53cfm....by far the highest I've seen.
Understood. Even at 80% efficiency (which I would question, knowing how badly things perform in the field), you're still adding latent load to the house. On my projects I often have to decide between an HRV/ERV and a ventilating dehumidifier for budget reasons. The houses I have with ERV/HRV have moisture problems indoors, it's driving me nuts. So I'm now leaning towards pressurization and dehumidification as my primary method, unless the house calls for something else.
Love the geeky HVAC stuff. I got a Mitsubishi mini split for my home office in Dallas because of your awesome videos and I couldn't be happier. Is there anything new going on with central HVAC technology (my 1965 ranch will likely need a changeout soon)?
You can buy vrf tech in central systems now including Trane, Carrier, Lennox, Rudd, etc. They are usually called Inverter Systems but have the conventional ducted air handler capability. Mitsubishi also sells an air handler. I would buy the 10 parts and labor on these systems as the electronics are usually first generation and expensive.
Very impressive. 😄
Just had one install today at our house.
Any feedback after few months of operating?
So Matt, with an independent duct system (your preferred method), how do you balance the system to account for things like bathroom fans, range hoods, and dryer vents. Intermittent ventilation components are going to change the positive/negative pressure of the house by as much as 100 cfm. Do you just accept that during intermittent ventilation you're overwhelming the ERV? Also, I'm planning to draw air from the upstairs and dump it near a return in the basement. Do you think this is a cost effective solution for an independent duct system?
@Matt Risinger any response to above?
Working on a small project right now and need to add an ERV to wrap things up. Searched for this unit, but can't find it anywhere online yet. I just emailed panasonic asking them about release dates and pricing ... waiting for reply. I know that they had supply problems on their old ERV models at times ...waited 6 months for one once. Wondering if anyone has any info on availability on these new units??
If it's 20deg outside, what temperature will the fresh air coming in.
But I want to hear it run! How loud are these things?
Where does humidity go?
I would like to see a bathroom exhaust fan with a filter (right after the trim). They always seem to die an early death due to moist dust collecting on the blower.
I had the same concern after replacing the builder's fans in our bathrooms with the Panasonic ones. What I did is I bought a couple 1" filters (the low MERV ones) and cut them to size and placed them after the fan's trim. Worked perfectly. It is amazing how much dust gets trapped in these filters. I change them as needed.
I currently use an inline fan. It is probably caked with dust but it is hard to access and clean. If I ever replace it, I'll rig up some sort of filter.
You link shows unit not available might want to update so I can get you some $$
We are currently building a ICF house and are planning on installing the Panasonic intel 200 ERV. We will be installing the unit in a utility room and running the duct work up through the attic. The attic is not insulated, can I use 6" insulated flex duct for my supply and return lines? My concern is that the flow rate be compromised with the flex duct. Your thoughts.
Matt, that is outstanding! what a gr8 improvement!
When I designed and built my house 1.5 years ago I ended up using the Mitsubishi Lossnay ERV.
The single biggest problem I have is getting the ERV to run at the speed I need for my balance to your of the system.
My calculations using either 62.2 or Doc Joe Lstiburek's BSC - 01 indicate I need between 40-50 cfm. However I don't seem to have a way to get the Mitsubishi to run a 50cfm. Mitsubishi did provide me a modual which gets it to 100cfm but at that level I'm over ventilating way too much.
Do you have any advice?
Eric Kessler sorry but I am not familiar with that model. Wish you the best. Matt
You could always add a timer that turns the Erv on and off. So let's say you need 50 CFM from a 100 CFM unit you could have the timer set to only run the Erv for 30 minutes in a 1 hour period.
Hi Matt, do you think that Panasonic's ERV would be a good stand alone system for an indoor pool room. The pool is small 8x12 and has an insulated cover. Or would it be better to pair it up with a dehumidifier?
+sherryl104 I wouldn't use for that purpose. A Dehum is a better choice.
Matt, any idea on what the efficiency is on this unit? I was planning on using the Zehnder NOVUS 300 that's over 90% efficient, would be interesting to see a detailed side by side comparison.
Johnintoit not sure. Need to dig into that spec. A side by side comparison would be very interesting. A big selling point of this one is price. I'm guessing it's 50% less than the Zehnder unit
Novus 300 at 90% is an HRV. The Panasonic is an ERV. HVI data is here: hvi-1491.quickbase.com/db/bh6688vwb?a=dr&ifv=1&rid=10060&dfid=12
After speaking with Larry from Zehnder we switched from the Novus 300 to the ComfoAir 350 ERV based on my climate and needs, thanks for the information John.
+ Johnintoit
I'm glad you brought up the Zehnder unit! That comfo air 350 has a lot of features that are definitely attractive (summer bypass, boost modes, digital controllers). It looks like the 200DX ERV RecoupAerator is similar. I'm looking for one with these features, but have no room in my house, so thinking of throwing it in the ceiling...
+ Matt Risinger
Any update on the intellibalance install? Does this unit have any features mentioned above? I wasn't even able to find a digital controller - is it basically just on or off?
I can't find ERVs on the website
This unit is not available yet, coming soon.
I don't understand how the FV-NLF46RES - Recessed Inlet is $120 with no fan, and the slightly larger FV-08VRE2
Includes a fan at 80CFM for only $30 more. I'm installing the updated Panasonic ERV with the boost switch to run as an exhaust and would love to run the recessed inlet, and will ultimately pay that price, but it seems ridiculous.
Matt, any chance this new unit is going to be PassiveHouse certified?
Martin Gravel not sure. Need to ask my Panasonic people...
What is a ERV and why do l need one.
A bit of a improvement but still not there..... The big problem I have with any ERV is they don't have multi damper controls on exhaust vents. If I have one exhaust zone such as a bathroom that needs full attention to remove humidity, It should have computer controls for the option of adding dampers with the option to open or close other exhaust vent. It might be possible depending on the make and model doing this using Arduino and write custom code, but I shouldn't be having to do this....The manufacture should be providing the controls for this. I think sometimes the government needs to get involved and force manufacture to give consumers the full product and not some half baked system.
Why aren't the filters metal? Anybody know?
why would they be metal?
First of all,....what is an ERV? Perhaps you should explain or define that first. I looked it up, but why didn't you explain that first up.
+garyhope2 thanks for the feedback. I did assume that in the beginning. Might need another video explaining ERV vs HRV and when/where to use one.
Sorry I listened to you This is a piece of junk. It arrived DOA. No local service. It is now off the market. I am now looking for a new ERV. You need to do some more research on the products you are flogging. Never going on your recos again
