A heat pump tumble dryer is a type of dryer that uses hot air to absorb moisture from clothes, and then passes the air through an evaporator to remove the moisture. The dryer then reuses the hot air once the moisture is removed, making it more energy-efficient than other types of dryers. Here are some key features of heat pump tumble dryers:

• They use a closed-loop heat exchange system to dry clothes at a lower temperature, providing better protection for your laundry.
• They offer great energy savings, keeping your utility bills to a minimum.
• They take slightly longer to dry clothes compared to condenser tumble dryers, but some models feature RapiDry™ technology that allows for shorter drying cycles while still maintaining high energy efficiency.
• They are more expensive than other types of dryers, but they are a good long-term investment for those who frequently use a dryer.

Heat pump tumble dryers are similar to condenser dryers in that they both have a water tank, but heat pump dryers reuse the heat generated, while condenser dryers use a heating coil. Vented tumble dryers are becoming increasingly rare due to the complexity of installation and high running costs.
