Vented dryers send moist, warm air out of a hose through an open vent or window, while condenser dryers send water from clothes into a container that requires removal and emptying on a regular basis. Both types of dryers have benefits and drawbacks.
The advantage of a condenser dryer is that the consumer can install it wherever he wants. There is no need to connect this dryer to an external vent. As long as the room has plenty of ventilation, a condenser dryer effectively removes the moisture from clothes. As the dryer operates, the damp, moist air moves through a hose to the collection chamber. Once there, the water condenses back to liquid form, pooling there until the consumer removes it and empties it.
Vented dryers need placement within a few feet of a duct or window. A hose runs out the back of the dryer, carrying the damp, warm air with moisture from the clothes, with the purpose of expelling it. On a cold day, when someone operates a dryer, it is common to see steam coming from the vent on the outside of the building. This type of dryer is more convenient because it does not have a tub to empty, and it does not require placement in a well-ventilated room. Vented dryers are more common in dedicated utility rooms.
