Choose a washer-dryer when only one space is genuinely available and you can adjust the load for drying, which is often smaller than the washing capacity. If you have room for a separate appliance, a condenser or heat pump tumble dryer avoids the need for an external connection; a vented model is only suitable if a compatible air outlet already exists.
You have a single space for laundry and want to wash and dry in the same appliance. The difference between washing and drying capacity, along with your willingness to accept longer cycles, becomes crucial. Que Choisir highlights that washer-dryers have a lower drying capacity than washing capacity.
You cannot drill through a wall or connect a duct to the outside. Condenser tumble dryers, including heat pump models, can be considered without an external connection, according to Que Choisir; nevertheless, check the room’s ventilation, how condensed water is handled and the maintenance requirements specified for the model.
You have a dedicated space and want to avoid regularly splitting laundry loads before drying. In that case, a separate tumble dryer should be compared first, particularly for capacity, programme length and electricity consumption.
Start by measuring the space and checking whether an air outlet is available, then compare the actual drying capacity and the day-to-day maintenance requirements.
| Priority | What to check | Your needs |
|---|---|---|
| Installation without an external outlet | Identify the technology: condenser or heat pump models do not need an external duct, while vented models require a compatible opening or duct. Also note the clearances specified in the manual. | I need to dry laundry without drilling through the façade or installing a duct that is incompatible with the property. |
| Capacity that is genuinely useful | With a washer-dryer, compare both stated capacities: washing and drying. For a separate appliance, match the stated capacity to your usual loads. | I want to avoid removing some clean laundry before drying or running several cycles. |
| Electricity and programme length | Compare the energy label and the duration of the programme for a comparable load. The Institut national de la consommation states that a heat pump can use up to around three times less electricity than a traditional vented or heated-air tumble dryer. | I want to limit electricity use without choosing a cycle that is too long for my laundry routine. |
| Humidity and maintenance | Check the collection tank or drainage connection, access to the filter and the required maintenance tasks. Provide a well-ventilated space in accordance with the manual. | I want to manage condensed water and regular maintenance without making indoor humidity problems worse. |
A washer-dryer’s drying capacity is lower. An appliance advertised as 9 or 10 kg for washing may require you to remove laundry before drying or split the load.
Always read the washing/drying format, such as 10/6 kg, and choose according to the amount you want to dry in one go. Que Choisir identifies this capacity difference as a structural limitation of two-in-one appliances.
A vented tumble dryer must direct moist air outside through a suitable opening or duct. Without this infrastructure, it will not meet your installation requirements.
Physically check the available opening or duct, then consult the manual to confirm the diameter, permitted length and route of the duct before buying.
Condensed water must be collected or drained, depending on the model, while filters and the condenser require the steps specified by the manufacturer. A poorly ventilated room can also worsen existing condensation problems.
Choose a well-ventilated, accessible location, then check the filter, tank or drainage hose and the maintenance instructions. A self-cleaning condenser does not mean you can ignore the manual.
A heat pump can reduce electricity consumption, but programme duration also depends on the model, load and programme selected.
Compare the energy label, the duration of the programme you need, the capacity, noise level and dimensions rather than assuming that one technology meets every priority.

Not necessarily. Que Choisir states that drying capacity is usually lower than washing capacity; for example, the Electrolux EW9W1166RA is listed as 10 kg for washing and 6 kg for drying. To run both stages consecutively without removing any laundry, follow the drying mode’s capacity limit.
Yes. According to Que Choisir, a condenser tumble dryer, with or without a heat pump, does not require an external connection. However, a vented model needs an external opening or compatible ventilation duct; also check the clearances and installation details described in the manual.
Not always. Condenser appliances can collect water in a tank that needs emptying, while some models accept a drainage hose. Bosch, for example, lists a water drainage hose for its WQG2450SFR; check that your installation is compatible with the manual for the model you choose.
Yes. A BUT guide to condenser tumble dryers recommends a well-ventilated room, as traces of moisture may be released into the room. If you notice persistent condensation, black marks or mould, the Agence Qualité Construction advises identifying the cause of the condensation rather than relying on the appliance to correct inadequate ventilation.
