I'm looking for comments and suggestions on whether it's safe and practical to run 20 feet of 4" metal exhaust duct horizontally from my relocated clothes dryer to tie into an existing 4" dryer duct which runs about 20 feet vertically. The existing vertical duct is uninsulated and is inside an always-warm house without air conditioning.
Thanks in advance for your replies. Darro
I would check with the manufacturer, they have specifics as to how long and how many bends are acceptable. You can always get a dryer duct booster fan
In addition to checking with the manufacturer for duct length, consider lint accumulation and clean outs. TB
The problem with extra-long runs is the fan inside the dryer may not be able to push the air that far, especially after a year or so & the tube gains some wind resistance in the form of lint that catches on things on the inside of the vent (this is why you don't screw dryer vent tube sections together). Wind resistance is also one reason why the flexible vinyl hose is not recommended (the other being it can catch on fire).
Check with the mfgr, see what they say about maximum vent length.
longer length means less efficent drying more energy use, adds regular maintence cleaning out line, and isnt a good idea.
would a NEW vent be shorter, if so install a new one.
Too long of a run! Buy yourself a Fantech dryer booster fan and install it near the END of the line just before it goes out of the house. Everyone should install one if the duct is over 12' long, it will help dry your clothes better, and cut drying times.

It is against most codes to "tie into" an existing dryer vent duct. Why can't you run this independently?

Who exactly does the certifiying of technicians for dryer exhausts and how long is the training period?

There's some stuff at the bottom of her page about it.
There's also a link to an online casino. Not something I'd want to be associated with...
Thank you for telling me about the online casino link. It was a mistake and has been removed.

No sweat Alisa. Considering this is a legit business page, it's bad ties. Obviously you agree.
