Heat pump dryers are energy-efficient appliances that use a heat pump system to dry clothes. Unlike traditional dryers that expel hot air, these dryers recycle warm air, reducing energy consumption. They work by drawing in moisture-laden air, heating it, and then circulating it through the clothes. The moisture is collected and condensed, allowing the air to be reused. These dryers operate at lower temperatures, which helps protect delicate fabrics and reduces the risk of shrinkage. While they may have a higher upfront cost, their energy efficiency can lead to savings on electricity bills over time, making them an eco-friendly choice.
