The energy consumption of a dryer depends on several factors:
- Type: Heat pump dryers use the least energy by recycling heat. Condenser dryers release heat into the room and consume more energy. Air-vented dryers use the most energy since they continuously draw and expel air.
- Drying programs: Energy use varies by program. Eco modes consume less energy by extending drying time, while Quick-dry modes use more energy for faster results.
- Load size: Overloading reduces drying efficiency and may require extra cycles, while underloading wastes energy.
- Moisture content: The wetter the clothes, the more energy needed. A high spin speed in your washing machine removes excess moisture and reduces drying time.
- Sensor drying: Dryers with moisture sensors stop automatically when clothes are dry, using less energy than timed drying.
- Ambient temperature: In colder environments, dryers—especially vented or condenser models—use more energy to maintain drying temperatures.
- Maintenance: A clean lint filter and well-maintained dryer improve performance and reduce energy consumption.
Which features have the greatest influence on the energy consumption of a dryer?
The following features have the greatest influence on a tumble dryer's energy consumption:
- Inverter motor (91% of A+++ dryers, 43% of all dryers): Inverter motors adjust speed and power consumption based on load size and drying conditions. This reduces energy waste compared to traditional motors, which run at a fixed speed.
- Humidity sensor (99% of A+++ dryers): Measures moisture levels in clothes and stops drying once optimal dryness is reached. This prevents overdrying, reducing unnecessary energy use.
- Selectable drying level (100% of A+++ dryers): Allows you to choose the exact dryness level (i.e., Iron Dry, Cupboard Dry). Lower settings use less energy by stopping sooner.
- Delay start option (100% of A+++ dryers): Lets you schedule drying during off-peak hours, optimizing electricity use and cost.
- Laundry detection system (50% of A+++ dryers): Detects load size and adjusts drying time accordingly. Smaller loads dry faster, saving energy.
- ECO function (38% of A+++ dryers, 22% of all dryers): Uses lower temperatures and extended drying times to consume less energy while still drying clothes effectively.
- ECO indicator (28% of A+++ dryers): Displays real-time energy consumption, helping you choose energy-efficient settings.
- Smart pairing (35% of A+++ dryers): Syncs with compatible tumble dryers to select optimal drying settings, preventing excessive energy use.
- Wi-Fi (43% of A+++ dryers, 29% of all dryers): While not directly reducing energy consumption, Wi-Fi connectivity enables smart scheduling, monitoring, and energy tracking for more efficient use.
- AI (18% of A+++ dryers, 11% of all dryers): Uses machine learning to analyze usage patterns and optimize drying settings for lower energy consumption.
Tumble dryers with more of these features tend to be more energy-efficient.
Additionally, 100% of A+++ dryers have a special filter type that simplifies cleaning. A clean filter improves airflow, enhancing performance and reducing energy consumption.
Other features common in A+++ dryers, though not directly affecting energy efficiency, include:
- Smart diagnosis (34%): Identifies issues early, preventing inefficiencies.
- Memory function (37%): Saves preferred drying settings for convenience.

Are dryers with multiple wash drying more energy efficient?
The number of drying programs does not directly affect a tumble dryer's energy efficiency. However, having more programs gives you better control over drying settings, helping you select the most energy-efficient option for each load.
Selecting Eco cycles—such as Eco Cotton in Hoover, Electrolux, Candy, and Bosch dryers—reduces energy consumption by optimizing drying time and temperature. Some advanced models, like LG dryers with the Eco Hybrid function, can reduce energy use by up to 21%.
Using the gentle drying function (available in 51% of tumble dryers) can also improve efficiency. This feature lowers drying temperatures to 50-60°C and extends cycle duration. A longer drying time at a lower heat setting consumes less energy compared to shorter, high-temperature cycles.
The number of drying programs available in tumble dryers with an A+++ energy efficiency class is shown in the following chart.

What are the most common programs in energy class A+++ dryers?
All A+++ energy class tumble dryers include basic drying programs such as Cottons, Synthetics, Mix, and Wool. Many also feature specialized programs, with the following being the most common:
- Outdoor/Sport cycle (87%): Designed for waterproof and sportswear fabrics, maintaining breathability while drying.
- Shirt cycle (72%): Reduces wrinkles and drying time for shirts, making ironing easier.
- Jeans cycle (36%): Optimized for thick denim, ensuring even drying without overheating.
- Duvet cycle (64%): Handles bulky items like duvets and pillows, preventing uneven drying.
- Hygiene cycle (54%): Uses high temperatures to remove bacteria and allergens.
- Allergy cycle (31%): Similar to the Hygiene cycle but specifically designed to reduce allergens in fabrics.
- Refresh cycle (77%): Freshens clothes with air circulation, removing odors without washing.
- Baby-care cycle (20%): Uses gentle drying to protect delicate baby clothes and fabrics.
A+++ tumble dryers typically have 10 to 22 drying programs, with an average of 14, similar to dryers of other energy classes.
Are tumble dryers with bigger capacities more energy efficient?
Tumble dryers with larger capacities tend to be more energy efficient in terms of kWh per kilogram. For example, 51% of 9 kg dryers have an A+++ rating, compared to 33% of 8 kg dryers and only 6% of 7 kg dryers.
There is no strong correlation between capacity and absolute energy consumption. While larger dryers might seem to consume more energy, data does not support this assumption. The average energy consumption per cycle for different capacities is:
- 7 kg: 2.25 kWh
- 8 kg: 1.87 kWh
- 9 kg: 1.89 kWh
- 10 kg: 4.1 kWh
Tumble dryers with 8 and 9 kg capacities consume the least energy on average. Energy consumption decreases up to 8-9 kg, then increases again for larger capacities. This is because 8 and 9 kg dryers incorporate advanced energy-saving technologies (i.e., better load sensing, more efficient motors) but do not handle excessively large loads, which require more energy input.
The most common A+++ dryers are 9 kg models (47%) and 8 kg models (45%).
To maximize efficiency, dry full or nearly full loads. Overloading reduces airflow and may require repeated cycles, while underloading wastes energy.

Are there any slim dryers with energy class A+++?
There are no A+++ energy class slim tumble dryers available. The depth of A+++ dryers ranges from 54 to 69 cm, meaning all models are full-sized.
If you need a slim tumble dryer, check models with A++ or A+ energy class. We have found some in these categories that are still highly energy-efficient.
