10 Basics To Know Heatpump Dryer You Didn’t Learn In The Classroom

What is a Heatpump Dryer?

A heatpump dryer is an energy-efficient alternative to a traditional fossil fuel-powered clothes dryer that draws air from outside instead of exhausting it inside. It saves more than just energy.

The compressor presses refrigerant through one set of coils, and pumps it through another set of coils for evaporation. This warms up the air which is used to dry clothes.

Energy Efficiency

Heatpump dryers use an air compressor and Evaporator together to eliminate the moisture from your clothes. This is a great option for those looking to cut down on their energy usage, heatpump dryer but do not have the space to hang clothes on a line. This is because heatpump dryers are ventless, meaning that they don’t require a ventilation pipe. Instead the air they use is drawn in from outside, and then pumped through filters before being pumped out. This closed-loop system saves energy by not wastefully exhausting the air inside that was warmed or cooled prior to entering the house (as conventional dryers do).

It’s also a good choice for those who wish to minimize their exposure to pollutants from the environment like pollen, dust and mold. When the air is circulated through a filter and condensed, the majority of UFPs (Ultrafine Particles), are drawn into the water and released as in the form of vapor. This keeps them from being broadcasted into the air and causing respiratory problems like they would be in a normal vented dryer (Sokhansanj 1984).

The efficiency of the energy used by a heatpump is the main benefit. It can save up to 50% of the energy required for drying compared to a traditional dryer. It is also able to save up to 30% of the energy used by a gas dryer, and up to 40% of the energy used by an electric dryer. In addition, it could save up to 10% of the energy required for cooling, compared to an ordinary dryer.

In the past, most research into the use of heat pumps for drying was focused on the heat pump itself. Recently, the focus has shifted to the overall performance. This performance can be measured in terms of COP (coefficient of performance) or SMER (specific moisture extraction rate, i.e. the amount of moisture removed per Kilowatt-hour), and drying efficiencies (Chua and colleagues. 2001).

The use of heat pump assisted drying is more economical and can provide a better product than hot air drying. A study conducted by Soponronnarit and Prasertsan showed that tomato slices dried using a heat-pump dryer had a more lively color and aroma when as compared to the ones dried using the hot air dryer.

Moisture Removal

A heat pump dryer has an evaporator which absorbs the water vapor of the wet fabric as it moves through it. The moisture is absorbed by the evaporator, and then disposed of into a drain pan, or drained directly into a sink. Heat pumps have a huge advantage over resistance dryers that depend on a heating component to generate heat. Heat pump dryers don’t add any additional humidity to your home, and they will save you time and money by reducing drying time.

Heat-pump dryers work in a similar way as conventional dryers, by compressing fluid. As the fluid is compressed, it absorbs heat from air surrounding it, and this heat is transferred to the wet fabric. These dryers are more efficient in energy use than standard models and can cut your energy bills by up to 30%.

Heat-pump dryers also have a smaller footprint than traditional dryers and require less maintenance. Heat-pump dryers have fewer parts and do not use resistance heaters which are the main cause of energy loss in traditional dryers. However, heat-pump dryers can have lint screens that require to be cleaned regularly and may require regular cleaning of the condenser coils, which are responsible for the transfer of heat from the evaporator.

The performance of the heat pump dryer can be measured by evaluating the specific moisture extraction rate (SMER) which indicates the dryer’s capacity, as well as the energy efficiency of a heat pump dryer is measured its COP (coefficient of performance) which is defined as the ratio of the heat that is emitted by the condenser to the work done by the compressor. In this study, a heat pump dryer (HPD) was experimentally evaluated using various designs and testing loads (4 kg and 7 kg). The HPD was equipped with an adsorption dehumidification device comprising a desiccant wheels at the inlet of the dryer.

The drying processes of the four designs of the HPD were studied by taking measurements of the SMER at a constant volumetric rate of 100 milliliters per hour. It was observed that the drying process was in the steady state for all three designs. Furthermore, it was demonstrated that the performance of the HPD improved when the device for adsorption was placed in the inlet of the dryer, rather than at the outlet.

Fabric Care

The heat pump dryers are made to dry fabrics at lower temperatures, which shields them from heat damage and helps extend their life. They also prevent shrinkage. They also provide a gentler cleaning experience than vented dryers, which makes them a good option for delicate or natural fabrics, such as wool and cotton.

The energy efficiency and fabric maintenance capabilities of heat pump dryers are enhanced by regular maintenance and use. Cleaning the lint filters as well as condenser units and emptying the water tanks, and clearing out the air intake vent regularly will ensure that your dryer is operating at its highest efficiency.

Regularly cleaning the lint filter in your heat pump dryer will help prevent the accumulation of lint, which can cause the appliance to overheat and reduce performance. It’s important to remove the lint filter after each drying cycle and clean it thoroughly by using warm water. Then, allow it to dry completely before reinstalling it in the dryer.

Emptying the water container in your heat pump tumble dryers pump dryer will stop the build-up and potential flooding of water that is too large that could cause harm to the appliance. This can be accomplished by removing the water from the container using the sink or hose. Then, rinse the container and allow it to dry fully before reinstalling it in your dryer.

To maintain optimal fabric care it is essential to choose the appropriate temperature setting for each load of laundry. To avoid damage to synthetic fabrics and sportswear it is recommended to use lower temperatures for drying. Upholstery and cotton fabrics can withstand higher temperatures. Bosch heat pump drying systems provide various drying programs to accommodate different types of fabrics and washing conditions.

A heat pump dryer fitted with PerfectDry can automatically adjust the duration of each cycle and the temperature to the desired temperature. This reduces guesswork and saves you time. For instance, the 40′ Express Cycle gets a tiny 2 lb load of laundry clean and ready to wear in just over an hour.

A heat pump washer dryer with heat pump is likely to be the best choice for you if you’re looking for a sustainable efficient laundry solution or if you need to improve your laundry area. Browse through Aztec’s top-rated brands and find a heat pump dryer that is suitable for your requirements.


The heat pump dryers are fairly new to the market in the United States. They have been used for a while in Europe and other countries. They’re also one of two types of ventless dryers; the other type is a condenser dryer. They are increasing in popularity despite their drawbacks.

In contrast to traditional vented dryers that use heat to dry laundry, and then let the warm air out, heat pump dryers recycle the energy they consume for the drying process. Heat-pump dryers are more efficient in energy use than conventional dryers and last for a longer time.

Dryers with heat-pump technology, in addition to being environmentally friendly are also more gentle on clothing. They can shield high-end fabrics because they don’t add heating to the cycle. They are therefore suitable for delicate fabrics like cashmere and wool. A heat-pump drying system is also more efficient than traditional dryers. It will save you time by decreasing the amount of wrinkles.

However, a dryer with a heat pump doesn’t eliminate the need for regular maintenance. Like all dryers, you need to clean the bottom container and the lint filter regularly. You’ll also need to ensure that the dryer is level so that it doesn’t strain its motor. Regular maintenance can significantly extend a heat-pump dryer’s lifespan.

The durability capabilities of a dryer with a heat pump is another advantage over traditional vented dryers. Traditional vented dryers require a vent pipe to be run outside your home. The pipe is required to get rid of moisture and heat, however it can get blocked over time. The life span of a traditional dryer could be significantly extended with regular maintenance which is much simpler than removing the entire wall on the exterior of your home.

The drying systems that use heat are more tolerant of humidity than vented models and can be run at lower temperatures, which is ideal for people with sensitive or allergic skin. Some of the dryers that use heat can run on the standard electrical circuit of 120-volts and 15 amps. This is ideal for those who live in apartments or homes with limited wiring.
