does heat pump dryer shrink clothes



Heat pump dryers have gained popularity in recent years due to their energy efficiency and gentler drying process. One common concern among consumers is whether these types of dryers shrink clothes. In this article, we will explore how heat pump dryers work, their impact on clothing, and provide valuable tips to prevent shrinkage. So, if you're curious about whether heat pump dryers shrink clothes, read on!

Understanding Heat Pump Dryers

Heat pump dryers work by using a heat pump system that extracts moisture from the air and then recycles it to dry clothes. Unlike traditional dryers that vent out hot, humid air, heat pump dryers use a combination of a heat exchanger, a compressor, and a refrigerant to dry clothes at lower temperatures. This innovative technology allows heat pump dryers to use significantly less energy compared to conventional dryers.

How Heat Pump Dryers Affect Clothing

While heat pump dryers are designed to be more gentle on clothing than traditional dryers, there is still a possibility of shrinkage depending on several factors. Here are some key factors that contribute to potential shrinkage in heat pump dryers.

1. Material Composition

The material composition of your clothing plays a vital role in determining its susceptibility to shrinkage. Natural fibers such as cotton, wool, and cashmere tend to shrink more than synthetic fibers like polyester or nylon. It's important to check the care instructions on your clothing labels to determine the best drying method.

2. Heat Settings

Heat pump dryers offer a variety of heat settings to choose from. Opting for a higher heat setting may increase the risk of shrinkage, especially for delicate fabrics. It's advisable to use lower heat settings or even opt for air-drying when dealing with delicate or shrink-prone garments.

3. Garment Size and Fit

Tightly fitted clothing is more likely to shrink compared to loose-fitting garments. Fabrics tend to shrink in high heat, and tight-fitting clothes may constrict further during the drying process. To minimize potential shrinkage, consider selecting a larger size when purchasing clothes.

4. Overloading the Dryer

Overloading your heat pump dryer can lead to uneven drying, and therefore, increase the chances of shrinkage. When the dryer is overloaded, clothes may not have enough space to circulate properly, resulting in longer drying times and higher heat exposure. Ensure adequate space for clothes to tumble freely to avoid shrinkage.

5. Correct Drying Time

Over-drying your clothes can also cause shrinkage. Even with a heat pump dryer's low-temperature drying, leaving your clothes inside for an extended period can lead to excess drying, resulting in potential shrinkage. Always set the appropriate drying time based on the fabric type and moisture level to avoid over-drying.

Preventing Shrinkage in Heat Pump Dryers

Although heat pump dryers have a lower risk of shrinking clothes, taking preventative measures is essential to ensure your garments remain in top condition. Here are some useful tips to prevent shrinkage when using a heat pump dryer.

1. Sort Your Laundry

To minimize the risk of shrinkage, sort your laundry based on the fabric type and care instructions. Separate delicate fabrics from sturdy ones to prevent damage and shrinkage. This sorting process will help you determine appropriate drying settings for each load.

2. Use Gentle and Low-Heat Settings

For delicate, shrink-prone fabrics, always use lower heat settings or even the air-dry option. Heat pump dryers often have specific settings for delicate or low-heat drying. Utilize these settings to reduce the risk of shrinking clothing.

3. Consider Air-Drying for Delicate Items

For extra delicate items or those that are susceptible to shrinkage, consider air-drying them instead. Air-drying is the gentlest method of drying clothes and is extremely effective in preventing shrinkage. Invest in a drying rack or use a clothesline to air-dry delicate garments.

4. Follow Care Labels

Always refer to the care labels on your clothing before drying them in a heat pump dryer. The care labels provide important information on how to wash and dry your garments properly. Following these instructions will minimize the risk of shrinkage.

5. Pay Attention to Garment Size

If avoiding shrinkage is a top priority for you, consider purchasing clothes that are slightly larger than your actual size. This extra room will allow for any potential shrinkage without compromising the fit and comfort of your garments.


In conclusion, heat pump dryers are generally gentler on clothes compared to traditional dryers. However, there is still a possibility of shrinkage, especially with certain fabrics and incorrect drying practices. By understanding how heat pump dryers work and implementing preventive measures, you can minimize the risk of shrinkage and keep your clothes in excellent condition. Remember to sort your laundry, use appropriate heat settings, follow care labels, and, if needed, consider air-drying delicate items. With proper care and attention, you can enjoy the benefits of a heat pump dryer without worrying about shrinking your clothes.
