I am building a 1300 chalet style cabin in the mountains of Eastern Arizona. The builder who framed the shell installed a 2 x 4 wall behind the location of the washer & dryer (a bedroom / closet is located behind the laundry room). I think I will either need to vent the dryer up and through the upper floor joists or down and through the lower floor joists. Is either way more correct than the other? Hot air tends to rise doesnt it? Can it be vented into the (vented) crawl space (3 – 5 feet on avg of space). Or do I need to vent it to the outside of the house?
Thanks for any suggestions…..

Vent it up and out. Venting into a crawlspace, or attic for that matter is just asking for trouble. Also, I have had good luck using 4" PVC DWV pipe, it's solid, durable, smooth and cheap. However, run a ground wire just in case of static, I think a piece of bare 12 AWG copper from the frame of the dryer laid inside the pipe to the vent should suffice. Good Luck.
*I agree, up and out is the way to go. If there is an outside wall nearby, can go out with a spring loaded wall hood. I like metal duct better for vent - fire proof and no static worry. Regular heating stuff is okay.
*Just don't use screws to hold it togeather, they will catch the lint.
*we use 4" pvc pipe w/ glued joints, vent it up if possible and take the shortest route and use the least number of bends possible, because they increase restriction, also as soon as you can, make sure there is pitch on the line because the vapor will condensate and you want it to drain to the outside and not fill up any bellies in your vent pipe never vent into an attic, the water vapor will cause roof damage.
*Aren't there static electricity problems with PVC? My understanding is that you need some type of ground in a PVC set up like you describe. Do I have something twisted around here?

HI-Where I live PVC won't pass code for dryer vent.Galvanized pipe only.Good luck BL
