What is a Heat Pump Dryer?
How They Work
A heat pump dryer operates as a closed system. It works much like a dehumidifier. This appliance uses a refrigerant system to manage air temperature and moisture. First, it dehumidifies air by passing it over a cold coil. This action condenses moisture from the air. Next, the air moves over a hot coil, returning it to its original temperature. Both the evaporator and condenser are inside the unit. This design keeps heat within the system. Only a small amount of extra heat comes from the compressor’s work. The condenser cools high-pressure refrigerant vapor into a liquid. This allows continuous refrigeration. A thermal expansion valve or capillary tube then regulates the refrigerant flow into the evaporator. This mechanism ensures efficient heat transfer. This advanced heat pump technology makes your clothes dry effectively.
Key Differences
You will notice several key differences with a heat pump dryer compared to traditional models. One major distinction is its ventless operation. This means you do not need an external vent to exhaust moist air. This simplifies installation significantly. Another important difference involves power supply. Many heat pump dryers, like those from LG and Miele, use a standard 120-volt outlet. This is a common household outlet. However, some models, such as Whirlpool’s heat pump dryer, require 240-volt power. Traditional electric dryers typically need a 30A receptacle and circuit, often consuming 5000 watts. The National Electrical Code (NEC) does not yet recognize heat pump dryers as a distinct category. This can lead to inconsistencies in how their power needs are assessed.
Pros of Heat Pump Dryers

This substantial energy reduction helps to decrease overall carbon emissions. Using modern energy-saving appliances like heat pump dryers can save more than 4 tons of CO2. This shows a clear link between your appliance choice and a healthier planet.
Cons of Heat Pump Dryers
Higher Initial Cost
You will notice a significant upfront investment with a heat pump dryer. These appliances generally cost more than traditional vented dryers. The average price difference between a heat pump dryer and a standard vented dryer is about $650. A typical vented dryer costs around $949. A standard heat pump dryer, however, costs roughly $1,799. This higher initial price can be a barrier for some buyers. You must consider this cost when making your decision.
Slower Drying Cycles
While heat pump dryers are energy efficient, they often take longer to dry your clothes. Earlier models had much longer drying times. Today’s heat pump dryers offer faster drying. They are still gentler on clothes. The heating phase in these machines is naturally longer than in traditional dryers. If you use the ‘Eco’ option for more energy savings, your drying times will extend even further. You might find that heat pump dryers take 50% to 100% longer to dry clothes compared to standard vented electric clothes dryers. This means you might need to plan your laundry days differently.
Load Capacity
You might find that heat pump dryers often have a smaller load capacity. Standard vented dryers typically offer more space for your laundry. This means you may need to do more loads to dry the same amount of clothes. A smaller capacity can be inconvenient for larger families or when you have bulky items like blankets. You should check the drum size before you buy.
Performance in Cold
Heat pump dryers can show poor performance in cold ambient temperatures. Their efficiency drops when the surrounding air is too cold. For example, at temperatures below 5–15 °C, the evaporator works at a much lower temperature. This leads to less efficiency. The system also experiences greater irreversibility below 10 °C. This happens because of the low evaporator operating temperature and a high temperature lift. You will see the system’s performance improve when ambient temperatures go above 20 °C. The evaporator’s heat exchange with the ambient air becomes more helpful then. This means if you plan to install your heat pump dryer in a cold garage or unheated basement, you might face higher energy costs and longer drying times.
