I’ve installed hundreds of fart fans. When you go to the store and press the test button like at Menards who happens to carry this Panasonic fan it is quiet as F. That’s because there is no back pressure. A 3 and 4” insulated flex line will cause some back pressure the fan struggles to push the air and you can hear the turbulence aka: vibration clear as day. Now reach up there and disconnect that flex pipe and quiet as ever. We always put a 4 to 6” adapter on the fan and pipe it outside using rigid where possible. Yes you can buy 6” exhaust vents. This eliminates almost all back pressure and vibrations
Yes, finally! Not enough has been said about this fan. Here in GA all the time I come across old dingy fans with their venting “pipes” just laying buried in the attic’s insulation. Old, older or newer houses - same thing. When I renovate or replace I use insulated flexible hose and drive it into the attics roof gable. I also install at the end short piece of pipe (for the sake of a sturdier and level install) with one of those plastic louvered vent covers to prevent any bugs or pest taking a ride in my pipe. Works like a charm. For all that 150CFM is not enough there is a even stronger model (230CFM) as well. Thanks for suggesting this one a while ago Steve! 👊👍💪
TIP: use a soffit exhaust vent only if you do not have a vented soffit! If you have a vented soffit the moist air will get sucked right back up into your attic space.
The Panasonic fans are a game-changer in terms of quiet. They’ve been around for a while…we had dinner with the project team for that product at PCBC back in the late 90s. I don’t remember if they were rolling it out that year or just had an “coming attractions” but it was literally 10% of the noise of a typical Broan/NuTone etc.
Nice work. Radiant floor heat also helps dry out the bathroom. If the vent fan is on a timer, and the radiant floor heat is working correctly, there will not be moisture problems. Also, as you know, the ceiling has to be painted with a vapor barrier type paint.
Radiant heat helps move moisture from liquid water to water vapor…but the moisture is still there just as higher relative humidity. You still need to move just as much air to expel that moisture out of the room.
@@HBSuccess Yes, radiant floor heat is not a substitute for a vent fan. Depending on amount of moisture. I am the only person who uses my bathroom, and I never need to run the vent fan or even use a bath mat. Everything dries out quickly even though the temp is set modestly.
I will have to ask my wife which model she purchased. But I told her to get 110cfm MINIMUM for our 85sq ft bathroom. I installed it (no light in the exhaust fan!) And now our mirror doesn't even fog over. It drops the temp in the room when it's on. Love it!
Im no expert but through my exploration in this subject, You’re supposed to vent your fans through the roof. I thought I heard its code on all new construction in many states. I have the roof mounted vent and insulated tube purchased. Just have to install it. This Old House episode.
Our old house never had bath vents but I want to add them when I remodel. They are stacked, with the 2nd floor bath having access to the roof via the attic. The main floor bath is right below it … I don’t know that I necessarily want to punch through the side brick to add the vent for that one? I would not be opposed to running the main floor vent up through the wall of the upstairs bath and meetup with the 2nd bath’s vent … and just run an attic fan on both baths whenever either bathroom is used. I’ve seen it done but there’s not much info out there on that.
I was looking at some exhaust fans in Home Depot and noticed that some said you need to install a GFCI. Makes sense because there is a lot of moisture that the fan will have But I also noticed that no one installs one so I’m a bit confused
I am currently looking to lay a vent from an existing bath fan that I thought vented outside. I was concerned about pest intrusion however. Will these grates on the end really keep roaches and such out?
You never do soffit vent it should always go out the roof no matter what now some times you can do it out the side of the house but only when the bathroom is in the basement and you go out the joist pocket further more the Panasonic fans are the best on the market.
Installed this today with new 12/2 wiring on its own 20 amp breaker to a decent single pole 20amp switch and it keeps tripping the breaker.... Can't figure out why. Does it need a special switch or something?
Panasonic has several modles, with sensors, LED lights, or without and different CFM, I've installed some of the retrofit version, fantastic stuff. Panasonic is the best vent fan. Silent, and lots of air flow. Long life. I replaced 3 rock grinder Broans, , all junk, Panasonic is the way to go. The mounting brackets, are genius. they have different models
Love your channel. You mentioned the model you got was adjustable from 110-150. The one you linked is 80-110. Did you change to the smaller model or just link the wrong one? Only reason I ask is my bathroom is similar size with 9ft ceilings and I have a 110 CFM fan on a small 3-4ft exhaust run out the side of the house and it can’t keep up with the moisture.
Sorry, yeah I should have clarified that. The adjustment switch has both readings on there. This one is the 150 www.build.com/panasonic-fv-1115vq1/s1428189
My bathroom ceiling is open, so while I am there, I want to change my bathroom fan for a new one, but I have a 3" diameter exhaust pipe, I’m considering changing it for a 4" pipe, which seems to be the standard now, I noticed that the new fans are made mostly for 4" exhaust, but some comes with adapters to fit 3" exhaust pipe. Is it worth the trouble changing for 4" exhaust ? would it be more efficient ?
Basically screwed. If your home is vented with 3 inch like mine, even though the house was built in 2004, I’ve got a foot and a half of what I call hamster cage lining type insulation that was sprayed in there. To try to root around without falling through the ceiling walking on the joist is a challenge. I haven’t been up in the attic looking around, but I did notice most homes, including mine in the neighborhood. Do not have physical vents in the roof or side of the house except for the dryer and the stove vent. It will be interesting to find out how this venting goes. It may be not worth having to make holes in your roof to try to replace 3 inch for 4 inch. Noticing your remark is over eight months old what did you do?
@@aviatortrucker6285 I changed for a 4" pipe. The vent goes through the brick wall, the fan is like 40" from it, so it is no far away. When I removed the old 3" vent, I noticed the hole in the brick wall was already a little more than 4", there was insulation in the gap. Then I put insulation around the pipe inside the wall. At the brick side of the hole, I poured mortar around the pipe, so I have clean 4" hole and it solidifies my brick there. It was easy to do. I installed an aluminum 4" vent with a clapper & a grille against birds. The fan is a Panasonic, quiet compared to the old Nutone.
@@Exoseven like I said, I dread going up there because of the spray insulation. It’s not like our 19 that’s in a bag laying neatly between the joists. I have to see where the 3 inch flex vent hose runs. It has to exit the house somewhere. If I have to change it to 4 inch I will have to see if an existing port or hole is in or near the gable. I have a second bathroom on the other side of the wall for the other two bedrooms, which also has a 3 inch run. I bet those two are put together somewhere and exit through a common duct. I really don’t want to go on the roof as it is dangerous to install a roof mount vent..
