If you regularly dry large loads and have a suitable space, a freestanding condenser tumble dryer—particularly a heat pump model—means you won’t need an external vent. A washer-dryer is a better fit when you can only accommodate one appliance, but you should check its drying capacity separately. For smaller amounts of laundry, an indoor airer may still be an option in a well-ventilated room, although it won’t solve poor ventilation in your home.
If you often dry laundry at home but can’t install a vent to the outside, consider a condenser tumble dryer. UFC-Que Choisir says this type of appliance can be installed without an external connection. You’ll still need to check you have enough space, how the water is handled and the installation requirements for your chosen model.
A washer-dryer combines both functions when there’s no room for a second appliance, either on the floor or in a compatible stack. However, UFC-Que Choisir points out that drying capacity is lower than washing capacity, so you may need to remove some items from a full wash load before drying.
For a small amount of laundry, sticking with an airer may save you from installing an appliance, provided the room can get rid of the moisture. ADEME notes that air-drying laundry releases a lot of moisture into the indoor air. Signs of mould or poor ventilation need to be dealt with separately.
First choose a drying method that suits your available space, then compare the actual drying capacity and the installation requirements of the specific model.
Consider this if: you dry laundry regularly without an external vent and can install a freestanding appliance.
Bear in mind: compare programme times across the models you’re considering, as well as their energy consumption.
Consider this if: you want a freestanding appliance that doesn’t need an external connection.
Compare: its energy consumption and cycle time with those of the heat pump models you’re interested in.
Consider this if: you genuinely only have room for one appliance.
Bear in mind: according to UFC-Que Choisir, drying capacity is lower than washing capacity. Check the full cycle time too.
Stick with this if: you have a small amount of laundry and a roomy, well-ventilated space or suitable extractor.
Keep an eye on: the moisture released by laundry, as highlighted by ADEME. An airer won’t fix poor ventilation.
| Criterion | What to check | What I need |
|---|---|---|
| Space and installation | Measure the space and the route the appliance will take to get there, then check the clearances in its manual. For a stacked installation, confirm that both appliances are compatible and that you have the right stacking kit. | I need to be able to load the appliance, access it for maintenance and install it without an external vent. |
| Drying capacity | Compare the drying capacity in kg with your usual load size. With a washer-dryer, check its washing and drying capacities separately. | Does a full load need to dry in one cycle, or can I remove some laundry before drying? |
| Cycles and maintenance | Compare the duration and energy consumption of the relevant programme in the product specifications. Check that the filters are easy to access and find out how to empty the tank or connect the condensate drain. | If I dry laundry often, the time it takes and the maintenance involved matter just as much as the space the appliance takes up. |
| Indoor humidity | If you use an airer, check the room’s ventilation or extraction. Distinguish moisture from laundry from an ongoing ventilation problem in your home. | I don’t want to add damp laundry to a room that already shows signs of excess moisture. |
With a washer-dryer, a full washing load may exceed the drying capacity. UFC-Que Choisir highlights this difference between the two functions.
Compare both figures in kg with your usual loads, and check the stated duration of the wash-and-dry cycle.
A condenser tumble dryer doesn’t need to vent air outside, but you still need to be able to open the door, collect or drain the water and access the appliance for maintenance. Bosch says that stacking requires compatible appliances.
Measure the space and check the appliance manual and, if applicable, the stacking kit instructions before ordering.
According to ADEME, air-drying laundry adds a lot of moisture to indoor air. Changing how you dry your laundry won’t, on its own, fix poor ventilation in your home.
Only use an airer in a well-ventilated room or one with suitable extraction. Get ongoing damp problems assessed separately.
A programme’s duration doesn’t tell you how much energy it uses or how much laundry it can dry. The trade-offs vary depending on the appliance type and cycle you choose.
For the models you’re considering, compare the duration, energy consumption and load capacity given for programmes that suit the way you’ll use them.
These examples refer to specific models and don’t represent every appliance made by each brand.
The WQG2450SFR is an example of a freestanding heat pump tumble dryer to consider if you have space for it on the floor or in a compatible stack.
The D0H1710 is an example of a heat pump tumble dryer whose manual is worth checking against the room where you plan to install it.
The EW7IW2856BG washer-dryer shows what to look at when one appliance needs to handle both jobs.
These models cover three ways to dry laundry without an external vent: a heat pump tumble dryer, a standard condenser tumble dryer and a washer-dryer. Compare their capacity and installation requirements with the space you have available.

A freestanding appliance to consider if you dry laundry regularly without an external vent and have space for it. The product title states a capacity of 8 kg and a C energy rating. Check the manual for dimensions, clearance requirements and how condensate is handled.

This appliance combines washing and drying when you only have room for one machine. The product title states a washing capacity of 8 kg and a drying capacity of 5 kg, so adjust the load before using both functions one after the other. The width given in the title doesn’t match the dimensions in the description, so confirm the measurements and installation requirements for this model.

Its condenser design makes it suitable for installation without an external air vent, subject to the model’s installation instructions. The product title states a capacity of 8 kg and OptiSense technology. Compare its energy consumption and programmes with those of other appliances you’re considering, then check that the water collection system is easy to access.

This freestanding tumble dryer is an option if you want an appliance without an external vent and have room for it. The product title states a capacity of 8 kg and a D energy rating. Check the manual for dimensions, clearances, maintenance and condensate drainage.

The heat pump technology makes this model worth considering for drying laundry without an external vent. Check its capacity before deciding whether it suits your loads: the title states 10 kg, while another description gives 8 kg. Also check the dimensions and condensate handling in the manual.
Not if it’s a condenser tumble dryer, including a heat pump model. UFC-Que Choisir says this type of appliance can be installed without an external connection. However, check how your chosen model collects or drains condensate and what its installation requirements are.
Yes, but only if both appliances are approved for stacking and you use a compatible kit. Bosch recommends checking that they are compatible. Consult the manuals for both models rather than simply placing one on top of the other.
Not necessarily: UFC-Que Choisir says drying capacity is lower than washing capacity. As an example for a specific model, Electrolux lists a washing capacity of 8 kg and a drying capacity of 5 kg for the EW7IW2856BG. A full washing load would therefore need to be reduced before drying.
No. An airer won’t solve persistent damp or poor ventilation. ADEME highlights the moisture released by air-drying laundry, so only use this method in a well-ventilated room or one with suitable extraction. Get the underlying problem in your home dealt with separately.
