If you regularly dry several loads, a separate tumble dryer lets you run a wash while another load dries, provided you have room for it on the floor or in a compatible stacking arrangement. If there’s only space for one appliance, a washer-dryer is a better fit, but its drying capacity may be lower than its washing capacity, so it’s worth checking the full cycle. You can still use a clothes airer if you have a well-ventilated spot where it won’t take over your living space for long.
Who are these solutions for?
People with space for just one appliance
A washer-dryer combines both functions, so there’s no need to transfer your washing between appliances. However, check how much laundry it can dry in one go: this capacity may be lower than its washing capacity.
Households that do several loads in a row
With a separate tumble dryer, you can start another wash while the first load dries. Stacking the appliances can free up floor space, but you’ll need appliances and a stacking kit that their manufacturers confirm are compatible.
People who don’t want laundry drying in their living space
If an airer takes up space for a long time, think about how well the room is ventilated too. ADEME notes that drying clothes indoors adds a lot of moisture to the air.
How do the options compare?
Separate tumble dryer
Consider this if: you regularly dry several loads and have room for a second appliance, either on the floor or in a compatible stacking arrangement.
The trade-off: it takes up space to install and may require a stacking kit that’s compatible with the exact models of both appliances.
Washer-dryer
Consider this if: you only have space for one appliance and want to wash and dry your clothes in the same machine.
The trade-off: the drum stays occupied for the entire cycle, and you may need to split a full wash load before drying it.
In a small flat without a balcony, start by working out how much space you really have. Then think about how much laundry you need to dry and which everyday compromises you’re prepared to make.
| Consideration | What to check | Who this matters to |
| Available space |
Measure the alcove and door clearance. For a stacked installation, check compatibility of both appliances and the kit using their exact model numbers. |
I only have room for one appliance and want to keep space clear to move around; around 33 % of consumers prioritise this space constraint. |
| Laundry volume and frequency |
Compare the drying capacity in kg with your usual loads, then check the full cycle time if you’re considering a washer-dryer. |
When I do several loads in a row, waiting for a full washer-dryer cycle to finish or splitting a load makes it harder to plan my day; around 27 % of consumers prioritise getting through their laundry quickly. |
| Noise, energy use and maintenance |
Check the specifications for the exact model, including noise in dB(A), energy consumption and programme times. Also look at the cleaning it requires. |
My appliance would be near my living space, and I want to be able to manage both its noise and maintenance; around 20 % of consumers prioritise these practical considerations. |
| Drying laundry indoors |
Consider how much space an airer takes up and how well the room where your clothes dry is ventilated. ADEME highlights the moisture released into the home when clothes are dried indoors. |
Because I don’t have another suitable room, damp laundry stays in my living space; around 20 % of consumers are mainly looking to reduce the clutter and moisture. |
Mistakes to avoid
-
Looking only at a washer-dryer’s washing capacity
Bosch and Electrolux specifications show separate capacities for washing and drying: an 8 kg washing model may dry 5 kg, while a 10 kg washing model may dry 6 kg. So a full wash load won’t necessarily fit in the dryer all at once.
Compare the drying capacity with your usual loads and check how long the corresponding wash-and-dry cycle takes.
-
Assuming any two appliances can be stacked
Similar widths don’t guarantee compatibility. Bosch advises checking the model numbers of the appliances and stacking kit; its 00576101 kit, for example, is designed for a full-size washing machine with a depth of more than 55 cm.
Choose your appliances and kit based on their installation instructions, then check that the height and access will work in your home.
You may need to buy a compatible stacking kit as well as the two appliances.
-
Comparing only the washing energy label
For a washer-dryer, information about washing on its own doesn’t tell you everything you need to know if you regularly run the full wash-and-dry cycle.
Check the energy consumption and duration for the wash-and-dry cycle on the energy label and specifications for the version you’re considering.
-
Replacing your airer without considering the room
An airer can still be useful for some loads, but ADEME notes that drying clothes naturally indoors adds moisture to the air. A new appliance will also need a suitable space that meets the requirements in its instructions.
Work out where you can dry clothes with suitable ventilation, then measure the space for the appliance before deciding whether the two solutions can work together.
Brands to consider
Bosch
Bosch models let you explore setups with a separate tumble dryer, a washer-dryer or stacked appliances.
- Bosch lists a 9 kg capacity and dimensions of 842 × 598 × 613 mm for the WQG2450SFR tumble dryer; the WNA13400FF washer-dryer has a stated drying capacity of 5 kg.
- For a stacked setup, check the kit and the exact model numbers of both appliances: the requirements for one Bosch kit won’t apply to every model.
Electrolux
Its washer-dryers show why it’s important to check washing and drying capacities separately.
- Electrolux lists capacities of 9/5 kg for the EW7W4954CA, 9/6 kg for the EW7W3916DA and 10/6 kg for the EW9W1166RA, for washing and drying respectively.
- Capacity figures won’t tell you how long your cycle will take, so compare cycle times and dimensions for the model you’re considering.
Miele
Its heat-pump tumble dryer specifications include useful figures for comparing specific models.
- Miele lists a weighted energy consumption of 101 kWh per 100 cycles for the TWL680WP and 92 kWh per 100 cycles for the TQ 1000 WP.
- These figures apply to two specific models, so you’ll still need to check their dimensions, programme times and installation requirements.
Beko
The D3H18D01W heat-pump tumble dryer is worth looking at if you want to check how easy it is to clean away lint.
- Beko says this model has a dual air filtration system to make condenser maintenance easier.
- Also check the noise level, dimensions and programme time for your needs; the filtration system alone won’t tell you whether it’s right for you.
Appliances for drying without an airer
These Joybuy appliances cover the two setups outlined above: a washer-dryer if you only have space for one appliance, or a separate tumble dryer if your home can accommodate a second one.

Frequently asked questions
Does a condenser tumble dryer need an external vent?
Not necessarily. Condenser models collect water in a tank, and some can be connected to a drain. Check the instructions for your chosen model for clearance and ventilation requirements; a water drain is not an air vent.
Can I put a tumble dryer on top of any washing machine?
No. Stacking depends on the appliances and a compatible kit. Bosch advises checking the exact model numbers; the requirement for a depth of more than 55 cm specified for its 00576101 kit doesn’t automatically apply to other kits.
Why check the drying capacity of a washer-dryer?
Because it may be lower than the washing capacity. Bosch and Electrolux specifications include configurations such as 8/5 kg, 9/5 kg, 9/6 kg and 10/6 kg. If your wash load exceeds the drying capacity, plan to remove some of the laundry before running the full cycle.
Can you still use an indoor airer in a small flat?
Yes, if you can make space for it and ventilate the room properly. ADEME notes that drying clothes naturally adds moisture to the indoor air, so bear this in mind if your airer needs to stay in your living space.
