If you have room for a separate appliance, a condenser tumble dryer, including a heat pump model, can dry laundry without any connection to the outside. A washer dryer is best suited to situations where only one space is available, provided you accept a lower drying capacity than washing capacity and longer cycles. An indoor airer requires a sufficiently well-ventilated room.
If you regularly dry laundry at home and have a dedicated space, focus your comparison on the condensation technology, capacity, cycle duration and maintenance requirements. UFC-Que Choisir states that a condenser tumble dryer can be installed without a connection to the outside.
A washer dryer combines both functions when two appliances will not fit in your home. According to UFC-Que Choisir, however, its drying capacity is lower than its washing capacity and drying takes longer than with a conventional tumble dryer.
An indoor airer can be suitable if you have a large room with good ventilation or an extractor fan. ADEME highlights that air-drying laundry releases a particularly large amount of moisture into indoor air.
Start by ruling out solutions that are incompatible with the lack of external venting. Then check the available space, the amount of laundry that can actually be dried and the cycle requirements before choosing an appliance format.
| Priority | What to check | Your needs |
|---|---|---|
| Suitability without external venting | Check that the product details mention “condenser” or “heat pump”. A vented model requires an opening to the outside or a ventilation duct. | I want a solution that can be used in the flat without creating an air outlet to the outside. |
| Size and capacity | Measure the width, height, depth, door clearance and required gaps. For a washer dryer, compare the drying capacity rather than the washing capacity alone. | I need to know whether a separate appliance will fit in the home or whether the space saved by a two-in-one model makes up for its lower drying capacity. |
| Duration, water and electricity | Compare cycle times and consumption for similar loads. With a washer dryer, also check the water consumption during drying given for the model. | I want to avoid a compact format or lower purchase price resulting in cycles that are too restrictive for how often I do laundry. |
| Moisture and maintenance | For an airer, choose a room suitable for ventilation. For a condenser appliance, check access to the filters, water tank and condenser, as well as the maintenance tasks specified in the manual. | I want to limit the moisture caused by damp laundry and maintain consistent performance from one cycle to the next. |
Without an external opening or accessible duct, this type of appliance does not meet the installation requirements. UFC-Que Choisir distinguishes these models from condenser tumble dryers, which can be installed without an external connection.
Rule this type out before comparing other features and look specifically for the terms “condenser” or “heat pump”.
The drying load is smaller than the washing load, so a full wash load may need to be reduced or divided before drying.
Compare the maximum drying capacity or the capacity for a complete wash-and-dry cycle with your usual load, rather than looking only at the washing capacity.
Splitting the laundry can add time when several drying loads are needed.
According to UFC-Que Choisir tests, dirt build-up can increase cycle times and consumption on some models, with effects varying according to the condenser system.
Check the manual for the cleaning procedure, access to the filters and condensation tank, and whether the appliance has a self-cleaning condenser.
Failure to carry out maintenance according to the instructions can extend cycle times and increase consumption.
Air-drying laundry increases indoor humidity. ADEME recommends taking the room’s size and ventilation into account.
Use an airer in a large, well-ventilated room or one fitted with an extractor fan. Otherwise, compare a suitable condenser solution.
In France, Bosch offers heat pump tumble dryers in a range of capacities, as well as washer dryers, depending on the reference and whether the appliance is freestanding or built-in.
In France, LG sells heat pump tumble dryers and washer dryers with separate washing and drying capacities.
In France, Beko offers heat pump tumble dryers and describes this system as a form of condenser drying that reuses heat.

A condenser solution for drying laundry at home without an external connection.
Listed capacity: 8 kg; stated dimensions: 60 × 65 × 85 cm; reversible door and humidity sensor mentioned.
Allow sufficient space for the door to open and for ventilation, then check the maintenance requirements for the filters, tank and condenser in the manual.
No. UFC-Que Choisir states that a vented tumble dryer requires an opening to the outside or access to a ventilation duct. If this is not possible, choose a condenser model, a washer dryer or an airer used in well-ventilated conditions.
Yes. ANIL reminds tenants that they must not alter rented premises or equipment without the landlord’s written consent. As the need for an air outlet or drilling depends on the project, tenancy agreement and, where applicable, the building’s regulations, choose a solution that does not require external venting if you do not have this permission.
Because a washer dryer dries less laundry than it can wash in a single load. UFC-Que Choisir reports drying capacities ranging from 2.5 to 8 kg depending on the model. The Bosch WKD28260FR, for example, is listed as 8 kg for washing only and 5 kg for washing and drying. When you want to run both functions consecutively, load the appliance according to its drying capacity.
Always follow the model’s manual first. UFC-Que Choisir highlights the importance of regularly cleaning the microfilter and condenser when requested by the manufacturer, as dirt build-up can increase cycle times and consumption on some appliances. A self-cleaning condenser does not remove the need to carry out other specified maintenance tasks.
Yes. The Q-WASH study reported by ADEME describes air-drying laundry as the activity that releases the most moisture into indoor air. Use an airer in a large, well-ventilated room or one fitted with an extractor fan, rather than in a small, enclosed room.
