A clothes dryer exhaust duct is run with several sharp bends and a long concealed length, then vented into an attic. Two problems with this install are:
a.It saves energy and looks neater
b.It increases airflow and dries faster
c.Lint buildup and moisture create a fire and mold hazard, and terminating in the attic is not permitted
d.It reduces the dryer's electrical load
Explanation
Excess length and sharp bends trap lint (a fire hazard) and reduce airflow, and discharging moist, lint-laden air into an attic causes moisture/mold damage and is not allowed; dryer ducts must terminate outdoors. It does not save energy, speed drying, or reduce electrical load.
