The washer-dryer draws warm air through wet clothes and the resulting moisture condenses in the sewer through cold water. The remaining dry warm air is recirculated to dry the clothes faster. Condensing washer-dryers consume a lot of water for drying and use more energy than washer-dryers with heat pump technology.
The washer-dryer draws warm air through your wet clothes and the moisture that condenses in the sewer. The remaining dry warm air is recirculated to dry the clothes faster. Models with a heat pump use less energy. The heat pump dries clothes gently at low temperatures, so you don't have to worry about heat damage or shrinkage.
