What about venting it into the crawlspace below? We don't have any
insulation between the floor joists down there, and the ground is
bare. The crawlspace is well ventilated (as is our drafty 50+ year
old house).

I ask because to get the vent down and out through an outside wall
will require about 3 90 degree bends along with about 40+ feet of
ducting. My only other alternative is to vent through the roof which
would be 2 90 bends and about 20' of ducting but I've read that it's
not good to vent vertically because the lint will clog easier.
space instead of horizontally thru an exterior wall to the
outside? - paul

The owner's manual will tell you the maximum allowable distance that
you can run the vent. You may be over that limit either way - 90 bends
creat much more drag on the air flow.

Having a too long vent run could be dangerous. The dryer won't be able
to exhaust the heat as quickly and there is an increased danger of
fire. Try and burn some lint some time - it burns beautifully.

There are inline vent fans to boost the air pressure in the duct and
help exhaust the air. The fan blades are designed to prevent lint
build-up, but they should be installed so you can access them to clean
off the lint anyway.
