For regular drying in a room without external ventilation, a heat-pump tumble dryer is an option worth considering: Guide Topten France indicates that this technology is among the most energy-efficient, although cycles can take longer. A washer-dryer is best suited to homes where there is no room for a second appliance; its drying capacity, which is lower than its washing capacity, should match the amount of laundry you actually dry.
If hanging laundry out is impractical but you have room for a separate appliance, compare heat-pump dryers based on their drying capacity, cycle times and energy consumption. Que Choisir and Guide Topten France identify these as useful comparison criteria.
A washer-dryer lets you wash and dry in the same space. However, according to Que Choisir, its drying capacity is lower than its washing capacity, and drying generally takes longer than with a separate tumble dryer.
Stacking a washing machine and tumble dryer saves floor space when the front-loading washing machine is compatible. Manufacturers require you to check the model references, depths and stacking kit suitable for both appliances.
Start by checking what can be installed in the room, then compare drying performance and consumption information from labels using the same rating scale.
| Priority | What to check | Your needs |
|---|---|---|
| Room and ventilation | Check whether an opening or external duct is available. For a condenser appliance, check the installation requirements and whether the condensate can potentially be connected to a drain. | I want to avoid an appliance that requires an unavailable external vent, or reduce the need to empty the water tank manually where a direct connection is possible. |
| Consumption and cycle time | Compare energy consumption in kWh and the duration of the ECO programme. Only compare energy ratings using the same A to G scale. | I am looking for a balance between electricity consumption and how long it takes before I can put the laundry away or use it again. |
| Drying capacity | Compare the kilograms that can actually be dried with your usual load. For a washer-dryer, check the washing and drying capacities separately. | I do not want to remove part of a large load before drying, or have the next wash held up by a two-in-one appliance. |
| Space saving | Measure the available space and appliance depth. Stacking requires a kit approved for both model references and their dimensions. | I want to free up floor space without placing a tumble dryer on a washing machine without a compatible fixing system. |
A vented model requires an opening to the outside or a ventilation duct. Without this installation, it will not meet your needs; Que Choisir also points out that it requires a sufficiently large room.
Before looking at the programmes, confirm the duct route, available opening and the requirements in the instruction manual. If these conditions are not met, compare condenser appliances instead.
An A+++/A++ rating on the old label cannot be compared directly with a letter on the current A to G scale.
Compare labels using the same scale, as well as energy consumption in kWh and the duration of the ECO programme.
The space saving is real, but the drying load is smaller than the washing load. Que Choisir also states that drying generally takes longer than with a separate appliance.
Check the washing and drying capacities separately. If you often dry full loads, a separate tumble dryer may be more convenient when the available space allows for a compatible stacked installation.
Depending on the model, a washer-dryer may also use water during drying; check this information in the product details and manual.
Stacking kits are not universal: manufacturers specify depth ranges, compatible model references and, in some cases, exclusions.
Keep the exact model references for the washing machine and tumble dryer, then check their compatibility in the manufacturer's documentation before ordering the kit.
A brand worth considering for households planning a stacked installation with a condenser or heat-pump tumble dryer.
A brand to consider for a range of heat-pump tumble dryers, with under-counter or stacked configurations available depending on the model.
A useful brand to compare when looking at condenser, heat-pump, vented and washer-dryer options for a space-constrained home.
This selection brings together separate condenser or heat-pump tumble dryers, as well as washer-dryers for homes with just one available space.

For a household with room for a separate appliance and no external duct.
8 kg drying capacity and a stated option for direct condensate drainage. Check the energy label, ECO programme duration, dimensions and the compatibility of any potential stacking kit.
Image unavailable
An option for washing and drying with a single appliance in a compact space.
Stated capacity of 10 kg for washing and 6 kg for drying, with Zeo-Cycle technology and a LintClear system. Check the dimensions, water consumption and wash-and-dry cycle duration before buying.
Image unavailable
Suitable for a single space with water inlet and drainage connections.
Stated capacity of 10 kg for washing and 6 kg for drying; dimensions of 600 × 850 × 590 mm. Check the duration and consumption of the complete cycle, as well as the clearances required for installation.

For a household that prefers a single machine and can plan for longer cycles.
Stated capacity of 11 kg for washing and 6 kg for drying, in a 60 × 85 × 60 cm format. The wash-and-dry cycle is stated to take 7 h 32 and use 90 L of water per cycle; check that this compromise suits how often you use the appliance.

A separate condenser solution for drying laundry without connecting an external duct.
8 kg capacity, OptiSense sensors, reversible door and dimensions of 60 × 65 × 85 cm. Compare the E rating and stated annual consumption of 235 kWh with labels using the same scale; also check programme durations and condensate management.
Yes. A condenser tumble dryer, including a heat-pump model, does not need an external connection. A vented model, on the other hand, requires an opening or duct to release hot, damp air; you must also follow the installation requirements in the instruction manual.
Yes, condensed water is generally collected in a tank. Some models support a direct connection to a trap or drain using a compatible hose or kit: check whether this is possible for the model you choose.
Not automatically, because its drying capacity is lower than its washing capacity. To run a wash and dry cycle without removing any laundry, the washed load must stay within the stated drying capacity; Que Choisir says this function is generally slower than using a separate tumble dryer.
Only if both appliances and the stacking kit are declared compatible. Requirements may include front-loading appliances, a specific depth range or certain model references; do not simply place the tumble dryer on the washing machine without a suitable fixing system.
Compare appliances using labels based on the same A to G scale, then look at energy consumption in kWh and cycle duration. European Regulation 2023/2534 governs the energy labelling of household tumble dryers.
