I can't determine if this is "new" technology for connecting the exhaust port of your dryer to the exhaust duct to your wall, but it apparently does not use a flexible, corrugated plasticized aluminum hose. It's some kind of smooth duct hose that is NOT corrugated. It's advertised to increase efficiency and lower electricity demand.

I have a mechanical man coming to fix and upgrade the dryer duct work under my house, and I thought it would be a good time to get rid of the corrugated flex hose.

Do you guys know about this, and have you used it on your dryer ?

Corrugated Hoses have proven to be lint collectors and a Fire Hazard, so in most cities by code they are not allowed to be installed. However some cities do allow them to be grandfathered in a home sale. Word to the wise, if you are looking at a house for purchase make sure any corrugated dryer hoses are replaced prior to the transfer. And insist it be done by the current code standards.

Obviously your plan to get rid of the corrugated stuff is a good thing to do even if won't save you a nickle in a years time.

Never heard of it, but I absolutely LOATHE those crappy tin foil hoses. Pieces of crap. I expected better for the 21st century than the same old 60 yr old garbage that never seems to connect wihtout a good hour of struggling and emotional turmoil.

Not the same but related, it seems like dryer exhaust heat and humidity should somehow be able to be utilized in the home in colder climates for Winter.

I’ve always installed 4” aluminum ducting from my dryer to the house outlet. I hate those corrugated flexible tubes.

Never heard of it but found this in a quick search.

I've always used solid piping. I hate the corigated stuff.

I used 3” foam core pvc pipe

That stuff is expensive. It also never actually says dryer vent compatible. It says it’s good to 160F. What do dryers run at, I can’t imagine they run that hot but I have no idea.

As for PVC pipe, how do you do that? Normally I connect the hose and then push the dryer back into place. With PVC there isn’t any real give, I can’t imagine how you make that work. Also not how you connect it to the machine. I’ve always used hose clamps but does that work with nonflexible PVC?

Honestly I don’t really worry about lint. I keep the hose to a minimum length and clean it out every once in awhile. If it’s short it doesn’t really collect much lint in my experience. It’s the long hoses with bends that get you in trouble.

I wouldn't use PVC hose for a dryer.
That hose is for dust collectors and other devices that need to move air but not involving heat.
PVC can burn and releases very toxic fumes when it does burn.

Pvc pipe with airflow builds static charge.

Thats why woodshop dust collection is either metal or has grounding provisions.

I would imagine a pvc pipe with large airflow (static charge) and lint would be a real bad idea.

4" aluminum pipe.

Reducing duct size, increases dry time and causes premature part failures.

I remodeled and went with a ventless dryer instead of putting in new piping.

The code called for rigid metal piping and I did not want to add a box to cover it.

PVC of any type does not meet code in most places for a dryer vent.

I have used this Deflecto in-line with the exhaust hose out of the dryer for years in the winter time. It is available from Amazon, etc.

Independent mechanical contractor. I have another company scheduled later IF this guy doesn't work out, I'm still waiting for his estimate. The other company is called "The Dryer Vent Wizard", appears to be a national franchise, but my initial call seemed good, the call taker knew more than I did about dryer ducting and venting. We'll see. I wish I could do it myself, like I do most other things on my house.

thanks

Growing up, my dad had something similar on our dryer to get some heat in the basement. I'm surprised it's not a problem to vent the exhaust gases inside though.

MARK... This is for the air exhaust used with electric or gas and not the burner output. Can you imagine what your clothes would smell like if the burner exhaust was used?
