We never use the dryer portion. With twin slides up front we have a lot of room to put up a folding clothes dryer rack and use that instead. When not in use, the rack folds and goes in one end of the closet. The dryer took too long taking up time that could be used to wash clothes.
Our dryer is vented and I wouldn't want to use an un-vented one.
