Also, PROPER VENTING
Is CRUCIAL.
White plastic venting should be, in my opinion OUTLAWED. It is a real potential fire hazard. Yes, it is easy to use. Easy as some of us here.
It can (and does) sag, reducing airflow, and increasing drying time, and drying costs. It can melt.
It can (and has!) caught fire. The next time you chat up a firefighter, ask him (or her).
I even think it voids warranties. (If it doesn't, it jolly well should.)
I don't have it in front of me right now, but I do know that the Installation directions for my Maytag LDG9806AAE had a big international circle NO for plastic venting.
There is a third way, and it is not the foil covered plastic vent, which is just as bad, though cute and shiny (like others here.)
The third way is semi-flexible metal. Much easier to use than sheet metal, but as safe as sheet metal. When my landlord put in my hookups, he used semi-flexible metal.
Say nasty things to me, write me evil emails, but I am sincere and serious about plastic vent hose being a Very Bad Idea. Even for an electric dryer.
Remember, lint is HIGHLY flammable.
The house, and LIFE you may save might be your own.
