Narrow utility room
You want to keep two separate appliances without needing two spaces on the floor. Que Choisir and Bosch France recommend checking that the appliances and stacking kit are compatible before you decide to stack them.
Who is this option for?
Frequent drying
You run cycles regularly and need to weigh up energy use, cycle time, capacity and maintenance. Que Choisir explains the trade-off: heat pump models generally use less energy, while conventional models often have shorter cycles.
Back-to-back loads
You prioritise cycle time to help you get through several loads of washing, while also considering energy use and the rules that apply to conventional models. Que Choisir highlights the usual difference in cycle times between technologies; the European Commission sets out the conditions for placing models without heat pumps on the market.
What to compare
First, compare the trade-off between energy use and cycle time. Then check separately whether stacking is suitable for both appliances and your utility room.
| What matters | What to check before buying | Who it matters most to |
|---|---|---|
| Compatibility and access | Check the model numbers of both appliances and the stacking kit, then check the dimensions, door openings and access for maintenance. | If floor space is limited, I want to keep two separate appliances without making them difficult to access. Around 33% of consumers prioritise compatibility and access in a narrow utility room. |
| Electricity use | Compare the kWh per 100 cycles on the current A to G label, and choose a capacity that suits your loads. | When I dry clothes often, I consider energy use alongside capacity and programme duration. Around 33% of consumers put energy use for regular drying first. |
| Cycle time | Compare the duration for the same programme type and load; also check the sales conditions for the model you are considering. | If I have several loads to get through, I consider how long they will take to dry without overlooking energy use. Around 17% of consumers prioritise faster cycles. |
| Maintenance and access | Check the instructions for cleaning the filters, accessing the water tank or drain, and the space needed for maintenance work. | In a cramped utility room, I want to be able to maintain and access the appliance without having to move the whole setup. Around 17% of consumers prioritise ease of maintenance and access. |
Mistakes to avoid
-
Choosing a stacking kit because the appliances appear to be the same width
Width isn’t the only consideration: kits have their own depth limits and may not be suitable for certain models. Que Choisir also highlights the importance of a stable installation.
Note down the full model numbers of the washing machine, tumble dryer and kit, then check them against the manuals and the manufacturer’s compatibility information before you buy.
-
Comparing an old A+++ rating directly with a rating on the current scale
Since July 2025, tumble dryers displayed in shops and online have used the A to G energy scale. This means an old rating cannot be directly compared with a rating on the new scale, as the European Commission points out.
Check the label for the exact model and compare appliances using data measured on the same basis.
-
Looking only at the stated cycle time or energy use
Que Choisir says heat pump models generally use less energy, while conventional condenser models generally dry clothes faster. The load and selected programme also affect how the appliance performs in everyday use.
Compare capacity, the duration of the programme you need, the stated energy use and how often you expect to use the appliance.
Brands to consider for these setups
Bosch
The brand’s heat pump tumble dryers and stacking kits are worth considering separately for your setup.
- Bosch France lists the WTH8520MFR with an 8 kg capacity and dimensions of 842 × 598 × 613 mm.
- The specifications for this model state that its condenser is not self-cleaning. Bosch stacking kit 00717525 is designed for washing machines with a depth of over 55 cm and is not compatible with certain Série 2 models. Check with the manufacturer that your appliances are compatible.
Electrolux
The brand’s stacking kits may be worth considering when available depth is a key factor.
- Electrolux France lists a depth range of 47 to 60 cm for its kit, which is secured to the wall.
- This range applies to this specific kit. The manufacturer advises checking each appliance using its PNC number.
Beko
The French range includes heat pump tumble dryers, with features varying between models.
- Beko describes the B5T48243W as a bPRO 500 heat pump model with an OptiSense sensor.
- Performance claims made by the brand are the manufacturer’s own statements. Check the label and instructions for the model you choose, as well as the appropriate stacking kit if you plan to stack the appliances.
Miele
Some of the brand’s heat pump tumble dryer models mention stacking with a suitable kit.
- The French product page for the TCA520WP 8kg Active mentions stacking and a condensation water tank.
- This does not confirm compatibility with a particular washing machine or kit. Check the model numbers and instructions for the appliances concerned.

Frequently asked questions
Can I put my washing machine on top of the tumble dryer?
No. When stacking appliances, the tumble dryer goes on top of the washing machine. Check the instructions for both appliances, make sure you have a compatible kit and ensure the floor is stable. The limits of a Bosch or Electrolux kit do not apply to all other models.
Is it illegal to buy a conventional condenser dryer in France?
No. Since 1 July 2025, EU rules have prevented domestic tumble dryers with a capacity of more than 3 kg and no heat pump from being newly placed on the market. This does not automatically prohibit the sale of appliances placed on the market before the relevant date. Check the status of the model on offer and its energy label.
How can I compare old and current energy labels?
Compare models using the A to G scale that has applied since July 2025, and information measured on the same basis. The European Commission advises against directly comparing an old A+++ rating with a rating on the new scale.
Does a condenser tumble dryer need to be connected to an outside air vent?
No, not for the condenser models described by the European Commission: water goes into a tank or down a drain, with no air duct leading outside. However, always check the installation and ventilation instructions for the model you choose.
Does every energy label already have to show a repairability score?
No. According to the European Commission, tumble dryers placed on the market from 1 January 2027 must show a repairability score on their label; it may be used before then. So, in October 2026, its absence is not enough to conclude that a rule has been broken.
