Without an external vent, a condenser tumble dryer collects water from your laundry without needing a duct to carry air outside. For new domestic appliances placed on the market in the European Union from 1 July 2025, the rules set out by the European Commission restrict this to heat-pump models. Before choosing, check the available space, how the water is handled, energy consumption, the Eco programme duration and maintenance requirements.
You want to dry your laundry without an exhaust duct. Que Choisir says a condenser tumble dryer can be installed without this connection. However, you’ll still need to measure the space, allow room to open the door and decide where the condensed water will go.
If you run consecutive cycles, choose a dryer capacity that suits your usual loads and is in line with your washing machine’s capacity. Also compare energy consumption and the Eco programme duration on the product information for the models you’re considering. Capacity alone won’t tell you which one is right for you.
If you’d rather not empty a tank or access parts for cleaning, check whether the model allows direct drainage and read the care instructions for the exact model. Electrolux France’s guidance, for example, recommends cleaning the lint filter after every cycle.
For a flat with no external vent, first make sure the appliance will fit and that you can collect or drain away the condensed water. Then compare models based on how often you dry laundry, the size of your loads and how much maintenance you’re prepared to do.
| Consideration | What to check | Who should consider it? |
|---|---|---|
| Installation and water | Measure the appliance and the clearance needed to open the door. Check whether the water collects in a tank or can be drained directly using a compatible connection. | Without an external duct, I want to make sure the appliance will fit and the water will be easy to manage; around 36% of consumers would make this their top priority. |
| Energy consumption | Compare the energy consumption per cycle or per 100 cycles, along with the corresponding capacity, on labels from the same generation. | If I dry several loads regularly, running costs are an important part of my decision; around 29% of consumers would put this first. |
| Capacity and duration | Choose a capacity to suit your laundry loads and check the full-load duration of the Eco programme. Check small-load options separately. | With large loads or a tight schedule, I don’t want to run extra cycles or be caught out by a longer-than-expected programme; around 21% of consumers would prioritise this drying routine. |
| Maintenance and noise | Check the manual for guidance on cleaning the filter and condenser, then look at the noise level listed for the model. | In a small room near living areas, I want to know what needs doing after each cycle and how much noise to expect; around 14% of consumers would make this their top priority. |
Que Choisir distinguishes between condenser dryers, which don’t need a duct to the outside, and vented dryers. A traditional condenser model is still worth considering if you’re looking at an older or second-hand appliance: the European rules for new domestic appliances placed on the market from 1 July 2025 don’t, by themselves, determine the status of these appliances. If you only dry laundry in a machine occasionally, a spin cycle suited to the fabric can also help with indoor drying. However, it won’t replace a tumble dryer if you need quick, predictable results.
A condenser tumble dryer doesn’t need to vent air outside, but it still takes up space, produces condensed water and shouldn’t block airflow around your home.
Measure the space with the door open, check where the tank is or how a hose could be routed, and keep the air inlets and outlets clear.
Depending on the model, water may drain into a tank or out through a waste pipe. The fact that a hose can be connected doesn’t necessarily mean the accessory will suit your existing set-up.
Check the manual and the accessories list for the exact model to confirm the connection requirements and what’s included.
If direct drainage is possible but your existing plumbing isn’t suitable, you may need a kit or an adjustment to your set-up.
The European rules introduced a new A–G energy label for the domestic tumble dryers covered from 1 July 2025. An old A+++ rating cannot be compared like-for-like with a letter on this new scale.
Compare product information from the same generation, looking at energy consumption, capacity and the Eco programme duration. The European Commission’s EPREL database lists this information for the models it covers.
This feature, where available, doesn’t necessarily remove the need to clean the lint filter. Electrolux France and AEG France provide separate care instructions for the filter and condenser on the relevant appliances.
Check the manual to see what needs doing and how often, rather than assuming the feature name tells you everything about maintenance.
These brands offer examples of features you can compare; they aren’t guaranteed across every model. Always check the exact model number and its installation requirements.
Worth a look if water drainage and condenser maintenance are important to you.
Worth considering if you want to compare capacity, energy consumption and the stated care offered to fabrics.
Consider this brand if you’re looking for a 9 kg capacity and can check the exact dimensions carefully.
Explore this brand to compare capacities and options for collecting or draining water across different models.
These three heat-pump tumble dryers suit shoppers looking for a condenser dryer without an external exhaust duct. They have different capacities, so before choosing one for your flat, check its dimensions, how it handles water and the details of its Eco programme.

Worth considering if an 8 kg capacity suits your laundry loads and you’re looking for an appliance without an external exhaust duct.
A connection for direct drainage is listed. Check the manual to find out which hose you need, whether it’s supplied and if it’s compatible with your drain.
Measure the space with the door open and check the energy label for consumption and the Eco programme duration.

Its stated 10 kg capacity is worth comparing with the size of your laundry loads, but don’t assume it will fit your available space.
Check the dimensions and door clearance, then see whether the model collects water in a tank or can drain it away, as stated in its product information.
If you’ll use it often, compare its energy consumption and Eco programme duration on the current energy label.

Consider this 8 kg model in relation to your usual laundry loads, rather than choosing based on capacity alone.
Before installation, check the dimensions with the door open and how the model collects or drains water.
Also check its energy consumption and Eco programme duration to compare its regular running costs with those of other models.
No. According to Que Choisir, a condenser tumble dryer can be installed without an external air exhaust connection, unlike a vented appliance. However, you’ll need to collect the water in a tank or, if the model and your installation allow it, drain it away.
Yes, if the tumble dryer supports direct drainage and you have a compatible drain. Check the manual to see whether a hose or kit is needed and if it’s included. Without a drainage connection, you’ll need to empty the tank as directed in the model’s instructions.
First, compare tumble dryers with labels from the same generation, then look at energy consumption, capacity and the Eco programme duration. For domestic appliances covered by the new A–G label, which applies from 1 July 2025, the European Commission also lists noise levels and condensation efficiency in EPREL.
At the very least, follow the care instructions for your model, even if it has a self-cleaning condenser. Electrolux France and AEG France both highlight the importance of the lint filter and, for the relevant appliances, checking the condenser. A blocked condenser can affect how the appliance works.
No. Mechanical ventilation doesn’t remove the need to check the tumble dryer’s installation requirements or keep your home’s air passages clear. The French decree of 24 March 1982 on home ventilation provides for air inlets in main rooms and outlets in service rooms. You should also check the manual for the clearances and connections required for your appliance.
