Without external venting, a condenser tumble dryer or heat-pump model is suitable, unlike a vented model. Choose a heat-pump dryer if you have room for a separate appliance and want to keep electricity consumption under control; a washer-dryer is more suitable when only one space is available, provided you accept a lower drying capacity and longer cycles. In all cases, check the room’s actual ventilation, installation dimensions, maintenance requirements and how condensed water will be managed.
You have an indoor space available, but no opening or duct leading outside. According to UFC-Que Choisir, condenser dryers can be installed without an external connection; room ventilation remains important.
If you have room for two appliances and dry several loads, compare drum capacity, energy figures, stated noise levels and maintenance requirements rather than focusing solely on the lack of a duct.
A washer-dryer can solve the space constraint. However, UFC-Que Choisir points out that its drying capacity is lower than its washing capacity and that cycles take longer.
Consider this if: you have room for a separate appliance and want to dry laundry without an external air connection.
You’ll need to allow for: a well-ventilated room, managing the water tank or a drain hose, and the maintenance specified in the user manual.
Choose this if: a separate appliance is possible and the electricity used during operation is an important factor in your decision.
You’ll need to accept: drying that can sometimes be slower than with a standard condenser model, without overlooking ventilation, drainage and maintenance.
Choose this if: one space needs to accommodate both washing and drying, or you want to run both operations consecutively without transferring laundry.
You’ll need to accept: loads must stay within the drying capacity, which is often lower than the washing capacity, and cycles may take longer.
| Priority | What to check | Your need |
|---|---|---|
| Installation without a duct | Choose a standard condenser or heat-pump appliance. Check whether water is collected in a tank or whether a drain connection is possible. | I need to dry laundry without drilling through the façade or connecting a duct to the outside. |
| Ventilation and humidity | Check effective ventilation, the required clearances and the temperature conditions stated in the manual. Do not enclose the appliance in a closed cupboard without ventilation. | I want to limit condensation on walls or windows and avoid adding humidity to a small room. |
| Capacity and duration | Compare drying capacity, not just washing capacity. For a washer-dryer, check the duration of a complete wash-and-dry programme. | My laundry needs to keep up without running multiple cycles or removing part of the load at the wrong time. |
| Energy consumption, noise and maintenance | Compare kWh/100 cycles, the noise class and dB figures on the same basis. Clean the filter after every cycle and maintain the condenser as required for the model. | I want to control electricity consumption, disruptive noise near living areas and routine maintenance. |
Even a condenser tumble dryer releases heat into its surroundings. Electrolux states that a room that is too small or poorly ventilated can encourage condensation on cold surfaces.
Measure the available space, check the clearances required in the manual and ensure proper ventilation while drying.
Drying capacity is lower than washing capacity. A full washing load may therefore require you to remove some laundry before drying or run the process in several stages.
Compare drying capacity, the duration of the wash-and-dry programme and the consumption figures shown on the label for the exact model.
Lint can reduce performance. Electrolux explains that a blocked condenser can increase energy consumption and damage the appliance.
Allow time to clean the filter after every cycle, check the condenser according to the manufacturer’s instructions and empty the tank when no direct drainage is being used.
kWh/100 cycles, the noise class and stated dB figures provide a more consistent basis for comparing models than a marketing claim.
Check these figures, the drying capacity and the dimensions of the exact model, including the depth needed to open the door.
In France, Bosch offers heat-pump tumble dryers, including models with 8 and 9 kg capacities.
Electrolux sells heat-pump tumble dryers whose product sheets specify the condenser technology, capacity, noise level and collection tank.
LG offers washer-dryers, including a Slim 9/5 kg model designed for installations where depth is a key consideration.
These Joybuy options include separate condenser tumble dryers, including a heat-pump model, for homes without an external air duct.

This option is suitable for separate drying in a home without an external duct when there is enough space for a dedicated appliance.
The product name indicates heat-pump technology, an 8 kg capacity and energy class C.
Before installation, check the dimensions, door clearance, ventilation clearances and the conditions for connecting the drain hose.

This separate condenser tumble dryer may suit you when you need to dry everyday loads without an external air connection.
The product name indicates an 8 kg capacity, condenser technology, propane refrigerant and the OptiSense system.
Check the manual for installation clearances, room ventilation and whether direct water drainage can be connected.
No. UFC-Que Choisir states that condenser tumble dryers, whether standard or heat-pump models, can be installed without a connection to the outside. Nevertheless, check the room’s ventilation and how condensed water will be collected or drained.
Do not assume that the absence of a duct is enough. Electrolux advises against installing the appliance in a closed cupboard without ventilation and recommends a well-ventilated room; above all, check the clearances and conditions specified in the manual for your chosen model.
Often, yes, when the appliance uses a collection tank and no drain hose has been installed. Some models allow water to be drained directly: confirm this option and the required accessories on the product page or in the manual for the exact model.
The first figure refers to washing capacity and the second to maximum drying capacity. For a continuous wash-and-dry cycle, load the appliance according to its drying capacity; otherwise, remove some laundry before drying.
