A heat pump dryer is an energy-efficient appliance that uses a heat pump to dry clothes. Unlike traditional dryers that vent hot air outside, heat pump dryers recycle warm air within the machine. This process reduces energy consumption and is gentler on fabrics, making it a popular choice for eco-conscious consumers. These dryers work by extracting moisture from wet clothes and transferring it to a heat exchanger, where the air is heated and reused. This closed-loop system not only saves energy but also allows for lower drying temperatures, which can help preserve the quality of garments over time.
