Without an opening or duct to the outside, rule out vented tumble dryers and compare condenser models instead. A separate heat pump dryer is a good choice when you do regular loads and keeping electricity use down matters, while a washer-dryer is mainly suited to homes where space is limited, provided the load you need to dry is compatible with its drying capacity.
If your flat has neither an opening nor a duct for connecting a vented appliance, consider condenser tumble dryers and washer-dryers. UFC-Que Choisir states that a vented model requires an external opening or access to a duct.
A separate tumble dryer may be the more practical choice if you regularly dry towels, household linen or family-sized loads and have room to install it. Drying capacity and checking the energy label then become key considerations.
A washer-dryer can be a suitable option when only one appliance can be installed. However, check the drying capacity first, as it is generally lower than the washing capacity, before planning complete wash-and-dry cycles.
Choose this if: you have room for a separate appliance and regularly dry laundry.
Keep in mind: compare the eco programme duration, noise level and maintenance specified in the manual.
Choose this if: you want a separate appliance without an external duct.
Compare: the current energy label, capacity and duration of the same eco programme.
Choose this if: your flat does not have room for two appliances.
Accept that: drying loads are smaller than washing loads.
| Priority | What to check | Your needs |
|---|---|---|
| Suitable without external venting | Choose a condenser or heat pump technology. Check the clearances, electrical supply and water management requirements specified in the model manual. | I need to be able to dry laundry without making an opening to the outside or using an existing duct. |
| Actual drying capacity | Compare the drying capacity in kg with your usual load. With a washer-dryer, check the washing and drying capacities separately. | I want to know whether one wash load can be dried in a single cycle or whether I will need to split the loads. |
| Energy use and duration | Compare the kWh per 100 cycles, capacity and eco programme duration shown on the current energy label. Also check the stated noise level. | I want to limit electricity use without choosing a cycle that is too long for my daily routine. Since July 2025, Gifam states that tumble dryer labels use an A to G scale and show consumption for 100 cycles of the eco programme. |
| Maintenance and condensed water | Locate the lint filter, condenser, collection tank and any option for connecting to a water outlet. Follow the maintenance procedures set out in the manual. | I would rather know what needs to be done after each cycle and whether I will need to empty a water tank. |
Without an external opening or duct, this appliance does not meet the installation requirements of the property.
Rule out this category from the outset and focus your comparison on condenser, heat pump and washer-dryer models.
The drying capacity is lower than the washing capacity. A 9/6 kg machine can wash 9 kg, but can only dry 6 kg in one cycle.
Base your choice on the drying load you handle most often, rather than on washing capacity alone.
A full wash load may require several drying cycles or removing some of the laundry first.
Older classes such as A+++ are not read on the same scale as the A to G label applied to tumble dryers since 1 July 2025.
Compare kWh per 100 cycles, capacity, the duration of the same eco programme and the stated noise level.
Filters, the condenser and the water collection tank are all part of using a condenser appliance. A washer-dryer also requires regular maintenance of its accessible components.
Before buying, read the manual and identify the recurring tasks, as well as who will empty the tank or use the drain connection.

Yes. A condenser tumble dryer, including a heat pump model, does not need a connection to the outside. However, UFC-Que Choisir confirms that a vented tumble dryer requires an external opening or access to a duct. You should also check the model manual for the dimensions, electrical supply and water management requirements.
It becomes restrictive when you regularly wash loads close to the maximum capacity and want to dry everything in one go. A 9/6 kg washer-dryer can wash 9 kg but only dry 6 kg, so you will need to reduce the initial load or dry it over several cycles.
Check that you have a flat, hard floor, that the appliance is stable, that there is enough space for air to circulate underneath it, that the drainage matches the manual’s requirements and that the socket is earthed. Electrolux points out that the precise requirements depend on the model installed.
Compare appliances using the current energy label and the same eco programme. Since 1 July 2025, Gifam states that tumble dryers have been rated from A to G and that the label shows, among other details, kWh per 100 cycles, capacity, programme duration and noise information.
Follow the manual when cleaning the filters and condenser and emptying the water collection tank. With a washer-dryer, also maintain the accessible components and leave the door and detergent drawer slightly open when recommended by the manufacturer.
