Without an outside air vent, a condenser tumble dryer meets the installation requirements described by UFC-Que Choisir. If you only have space for one appliance, a washer-dryer could work, provided you plan your loads around its drying capacity, which is often lower than its washing capacity. A clothes airer is another option if you have a large, well-ventilated room, in line with the recommendations outlined by ADEME.
If you can’t connect an appliance to an opening or outside duct, compare condenser tumble dryers with a washer-dryer and a clothes airer. UFC-Que Choisir explains that a condenser tumble dryer doesn’t need an outside connection.
Drying capacity and programme duration matter if you need to dry several loads in a row. If you choose a separate appliance, make sure you also have enough space and follow the maintenance instructions in its manual.
A washer-dryer combines washing and drying in one appliance. Check its maximum drying load, though: UFC-Que Choisir notes that this is lower than its washing capacity.
First rule out any installation options that aren’t possible, then compare your laundry load with the available space and the consumption information for the appliances you’re considering.
| Priority | What to check | Depending on your needs |
|---|---|---|
| Connection and installation | Rule out vented tumble dryers if an outside vent isn’t possible. For a condenser model, check its manual for the electrical supply, installation and water collection requirements. UFC-Que Choisir confirms that it doesn’t need an outside air vent. | I don’t have an opening or outside duct to connect a tumble dryer to. |
| Load size and frequency | Compare the drying capacity in kg with your usual laundry loads and the duration of the relevant programme. With a washer-dryer, don’t confuse washing capacity with drying capacity: UFC-Que Choisir treats them separately. | I need to be able to dry laundry at a pace that suits my household, without routinely having to remove some of it after washing. |
| Consumption | Compare the figures on labels and product information for appliances in the same category, using the same programme basis. For a washer-dryer, look at washing and combined wash-and-dry figures separately, including water consumption. | If I dry laundry in a machine often, I want to compare the usage figures for the models I’m considering, not just their technology. |
| Space and maintenance | Measure the space available, including clearance for the door, and check access to the filter and water tank for the specific model. Bosch support advises cleaning the filter after every use on the relevant appliances. | I only have room for one appliance, or I need to be able to access it easily once it’s installed. |
| Drying on a clothes airer | Check that the airer will fit in a large, well-ventilated room. This is the condition for indoor drying highlighted in the Q-WASH study presented by ADEME. | I prefer to air-dry my laundry and have a suitable room, without permanently blocking space I need. |
You can’t always dry a full wash load in the same cycle. For example, LG lists the LG F964V50WRS as having a 9 kg washing capacity and a 6 kg drying capacity.
Compare both capacities in kg and base your load sizes on the drying capacity if you want to wash and dry in one go.
Looking at programme duration or energy class alone won’t tell you everything about how an appliance will work for you. Capacity, the reference programme and how often you dry laundry also matter.
To compare a standard condenser model with a heat-pump model, look at the published figures for appliances with similar capacities and on the same programme basis.
A condenser tumble dryer doesn’t need an outside air vent, but the space, power supply and water collection arrangements still need to suit the model you choose.
Measure the space, including with the door open, then check the model’s manual for installation requirements and drainage options.
Drying laundry indoors adds moisture to your home. The Q-WASH study presented by ADEME recommends using a large, well-ventilated room for this.
Before making a clothes airer your usual solution, check that you have a room that meets this condition.
Bosch offers the WQG2450SFR heat-pump tumble dryer, for example, which has a listed maximum capacity of 9 kg.
LG France lists the LG F964V50WRS washer-dryer as having a 9 kg washing capacity and a 6 kg drying capacity.
Miele France’s catalogue includes tumble dryers with listed maximum capacities of 7, 8 or 9 kg.
Electrolux presents its washer-dryers as a way to combine washing and drying in one appliance.
These models offer a separate condenser tumble dryer option for homes without an outside air vent. If your main concern is the space available, they don’t replace comparing a washer-dryer or clothes airer.

Its listed capacity of 8 kg can be compared with your usual laundry loads when considering a separate tumble dryer without an outside air vent.
The product name indicates a C energy class. Before deciding where to put it, check the manual for the dimensions, clearance and water-management requirements. Consult its energy label to compare consumption on the same basis.

This model has a listed capacity of 8 kg, making it another separate tumble dryer option to compare with your usual laundry loads.
The product name indicates a D energy class. Check the dimensions, water collection method and installation requirements for this model. Energy class alone isn’t enough to compare the appliances’ stated consumption.

Its listed capacity of 8 kg can help you assess whether this condenser model suits the amount of laundry you need to dry.
The product name mentions OptiSense, but that alone doesn’t establish which heating technology to use when comparing consumption. Check the energy label, depth with the door open and drainage arrangements before choosing a spot for it.

This separate heat-pump tumble dryer is worth considering if you’re looking for a solution that doesn’t need an outside air vent.
Its capacity is listed as either 10 kg or 8 kg in the product information, so confirm the exact figure before planning your loads. Also check the dimensions, water-management arrangements and stated consumption for this model.
Yes. UFC-Que Choisir says that a condenser tumble dryer can be installed without an outside connection, unlike a vented model. However, check the manual for your chosen model for installation requirements and how the condensation water is collected or drained.
Not necessarily: UFC-Que Choisir notes that its drying capacity is lower than its washing capacity. For example, LG lists the F964V50WRS as having a 9 kg washing capacity and a 6 kg drying capacity. A 9 kg wash load would therefore need to be reduced before drying or dried in several batches.
Measure the space available, including the clearance needed to open the door and access parts that require maintenance. Then check the model’s manual for installation, electrical supply and condensation-water management requirements.
Compare the figures on energy labels and product information for appliances in the same category, using the same programme basis. For a washer-dryer, look at washing and combined wash-and-dry figures separately, including the water used by the latter.
It can work if you have a large, well-ventilated room. This condition is included in the indoor-drying recommendations in the Q-WASH study presented by ADEME; it isn’t an assessment of the ventilation in your home.
