If you have room for two appliances, a separate heat pump condenser tumble dryer is the preferred option, particularly when stacked using a kit explicitly confirmed as compatible. A washer-dryer is best suited to situations where only one floor-standing space is available. However, its drying capacity is lower than its washing capacity, and cycles may take longer.
When there is only room for one floor-standing appliance or a stacked column, and air-drying is impractical, the choice comes down to the smaller footprint of a washer-dryer or the separate capacity of a compatible stacked setup.
For household laundry or large loads, a two-appliance solution helps retain separate drying capacity, provided you have enough vertical space and a compatible stacking arrangement.
Without ducting to the outside, a condenser tumble dryer, with or without a heat pump, or a washer-dryer can meet your installation requirements. UFC-Que Choisir explains that a vented tumble dryer requires an external opening or ventilation duct.
Start by measuring the available space and working out how much laundry you need to dry, then compare the usage data for the exact model.
| Priority | What to check | Your needs |
|---|---|---|
| Size and installation | Measure the width, height and depth, including the door opening. For a stacked column, check that the appliances are front-loading, the floor is stable, the tumble dryer will sit on top and the stacking kit suits the exact model reference. | I want to install drying appliances in a small room without assuming that a kit or stacking arrangement is compatible. |
| Energy, water and duration | Compare the kWh used by the reference programme, the duration and the energy label between comparable appliances. For a washer-dryer, check the washing-only and wash-and-dry cycles separately. | I want to limit running time and consumption without choosing based solely on footprint or purchase price. |
| Drying capacity | Compare the drying capacity with your usual load and, for a combination appliance, with its washing capacity. A washer-dryer may require you to remove some laundry before drying. | My laundry should be dry at the household’s actual pace, without unnecessarily running multiple cycles. |
| Maintenance and accessibility | Check access to the filter, water tank, door seal and controls. Also compare the noise level if the appliance is near a living area. | I want to load, unload and maintain the appliance easily despite limited space. |
A width of around 60 cm proves neither that the stack will be stable nor that the fixings are suitable for the tumble dryer. Bosch Home Appliances France states that a kit must be suitable for the tumble dryer.
Note down the exact references of both appliances, consult their manuals and confirm the kit’s compatibility before ordering.
Drying capacity is lower than washing capacity, so a full load may need to be divided. UFC-Que Choisir also points out that drying performance on this type of appliance does not match that of a separate tumble dryer.
First compare the drying capacity, duration and consumption of the wash-and-dry cycle for your usual laundry load.
A faster cycle or a lower purchase price does not, on its own, tell you how much electricity the appliance will use over time.
Compare the energy label, the kWh used by the reference programme, capacity, duration and noise level between models with the same capacity.
Without an external opening or access to a ventilation duct, this type of appliance will not meet your installation requirements. UFC-Que Choisir also states that it uses more energy than condenser models.
Confirm the actual duct route before choosing this type of appliance. Otherwise, focus your search on condenser models or a washer-dryer.

Worth considering when a single floor-standing space needs to accommodate both washing and drying.
Stated capacity: 10 kg for washing and 6 kg for drying; advertised features include Zeo-Cycle technology, 27 programmes, app control and a LintClear system.
A full wash load may need to be divided before drying. Check the dimensions, noise level, duration and consumption of the wash-and-dry cycle before buying.

A separate drying option for bulky loads without ducting to the outside.
Stated capacity of 10 kg, three drying levels, double-layer filter, refresh programme and LED display.
Before planning a stacked column, confirm the dimensions, clearances and a kit compatible with the exact washing machine.

Worth considering for separate drying in a room without an external air outlet.
Stated capacity of 8 kg, an Easy Cleaning 2-in-1 filter accessible through the door, direct condensate drainage, delayed start and a stated noise level of 64 dB.
Check the available space, door opening, programme duration and stacking compatibility before installing it in a column.

A separate drying option for everyday laundry when air-drying is impractical.
Stated capacity of 8 kg, adjustable drying levels, double-layer filter, refresh programme and LED display.
Measure the room and the required clearances. Do not assume that a kit or washing machine will be compatible with this appliance.

Worth considering for separate drying in a small utility room without an external duct.
Stated capacity of 8 kg, dimensions of 60 × 65 × 85 cm, reversible door, water collection tank, OptiSense sensors and a stated noise level of 66 dB(A).
Check the depth with the door open, the clearances and the compatibility of a stacking kit before considering a stacked installation.
No. The tumble dryer must be installed on top, and a kit suitable for the tumble dryer must be confirmed using the exact model reference. Bosch Home Appliances France also recommends following the manual and checking that the appliances are aligned once stacked.
Not necessarily: its drying capacity is lower than its washing capacity. UFC-Que Choisir states that drying capacities vary between models, so adjust the amount of laundry before starting a combined cycle.
Compare the washing-only and wash-and-dry cycles separately, rather than focusing on a single class. European energy labelling covers washing machines and washer-dryers, while ADEME reminds consumers that consumption is shown in kWh per 100 reference cycles.
No. UFC-Que Choisir states that a vented tumble dryer requires an opening to the outside or access to a ventilation duct. If this connection is not possible, choose a condenser model or a washer-dryer instead.
It is an option worth considering when electricity consumption matters, provided you compare models using the same reference programme. Also check the exact model’s capacity, duration, noise level, maintenance requirements and dimensions.
