What types of dryers are available and how do they differ?

There are two main types of dryers: vented and ventless. Vented dryers expel hot, moist air outside through a duct, requiring an external vent. Ventless dryers, including condenser and heat pump models, recycle air within the unit. Condenser dryers cool hot air to remove moisture, which collects in a tank or drains out. Ventless dryers are ideal for spaces without existing vents.
