According to UFC-Que Choisir, a condenser tumble dryer, with or without a heat pump, can be installed without an external connection, so a vented model won’t meet this requirement. To choose between a tumble dryer and a drying rack, first check the room’s ventilation, then compare the appliances you’re considering in terms of energy use, cycle times and maintenance.
If the room doesn’t allow for an external connection, a condenser tumble dryer is still an option. UFC-Que Choisir explains that this technology doesn’t require an external connection, although you’ll still need to check the room’s ventilation.
If you dry several loads each week, compare the capacity with the size of your usual loads and check the energy use stated per 100 cycles. It’s also worth checking how long the programmes you’ll actually use take.
A lack of windows doesn’t, on its own, tell you how the air is refreshed. Electrolux advises against enclosing a tumble dryer in an unventilated cabinet. For air-drying, ADEME recommends a large, well-ventilated room or one with an extractor.
Start by checking that the air is refreshed and that there’s enough space: whichever drying method you choose, these conditions need to be considered.
Worth considering: if you dry clothes frequently and want to compare appliance energy use closely.
Check: programme times, as well as the installation and maintenance requirements for the model you choose.
Worth considering: if cycle time is especially important: UFC-Que Choisir says these models generally dry clothes faster.
Check: the model’s energy use on a comparable label and the ventilation needed in the room.
Worth considering: if you have a large, well-ventilated room or one with an extractor, as recommended by ADEME.
Keep an eye on: the moisture released into your home as laundry dries, especially in a small, enclosed room.
| Priority | What to check | Your needs |
|---|---|---|
| Connection | Check the type of tumble dryer and the connections required in its manual. According to UFC-Que Choisir, a condenser model doesn’t need an external connection. | I can’t connect a vent to the outside. |
| Ventilation and space | Check the existing ventilation, the clearance specified and the model’s operating temperature range. Don’t install the appliance in a closed, unventilated cabinet, as advised by Electrolux. | My room has no window, so I need to know how the air is refreshed and where the appliance could go. |
| Energy use and cycle time | Compare figures expressed in the same units, such as kWh/100 cycles, then check the duration of the programmes you need. Don’t compare kWh/year directly with kWh/100 cycles. | With several drying cycles each week, I want to estimate the electricity used without overlooking how long each load takes. |
| Capacity | Match the drying capacity to your laundry loads and check the programme load limits in the manual. | I want to dry my washing without regularly having to split it across several cycles. |
| Water and maintenance | Check that the water tank and filters are easy to reach. If you want direct drainage, confirm that the kit is compatible and that the necessary accessories are included. | I’d like to know how often I’ll need to empty the tank and make sure the parts that need maintaining are easy to access. |
A condenser appliance can run without an external connection, but a poorly ventilated room or cabinet can encourage heat and moisture to build up. Laundry drying on a rack also adds moisture to the air indoors.
Check the room’s ventilation before you choose. Follow the model’s installation instructions and avoid placing it in a closed, unventilated cabinet, as recommended by Electrolux.
An annual figure on an old product sheet and a figure in kWh/100 cycles don’t measure usage on the same basis.
To compare two appliances, start with figures expressed in the same units and relate them to the number of cycles you typically run.
If the capacity is too small for the loads you want to dry, you may have to split a load of washing into smaller ones.
Match the tumble dryer’s capacity to your washing machine’s and check the load limits for the programmes you use.
Splitting loads means more cycles and more handling.
If there’s no direct drainage, you’ll need to empty the collected water from the tank. Electrolux also lists the filters and door seal among the parts to check if there’s excessive moisture.
Check that these parts are easy to reach. If you plan to use a drainage kit, make sure it’s compatible with the exact appliance model.
These details apply to the models mentioned, not to every appliance from each brand.
The brand offers heat pump tumble dryers and publishes information on installation and maintenance.
Bosch product sheets make it easy to check each model’s capacity and maintenance features.
Some LG models combine heat pump technology with a self-cleaning condenser.
These two 8 kg tumble dryers are presented as options for a room without an external connection: one is described as a heat pump model, the other as a condenser model. Check that their installation requirements are suitable for your room’s ventilation and available clearance.

Worth considering if you’re looking for a tumble dryer that doesn’t need an external vent. The product name lists heat pump technology, an 8 kg capacity and a C energy rating. Before installing it, check the manual for ventilation, clearance and water drainage requirements, and make sure its capacity suits your laundry loads.

The product name lists an 8 kg capacity, OptiSense and propane as the refrigerant. The description “condenser” isn’t enough to tell you whether this model uses a heat pump: check its technology, energy label and installation instructions before comparing it with another model.
No. According to UFC-Que Choisir, it can be installed without an external connection, whether or not it has a heat pump. You’ll still need to follow the ventilation and installation requirements in the model’s manual.
A lack of windows doesn’t give you the full picture: check how the room is ventilated and whether it meets the appliance’s requirements. In particular, Electrolux advises against enclosing a tumble dryer in an unventilated cupboard.
Yes, if the collected water goes into the tank rather than being drained away directly. Electrolux describes a drainage kit for some configurations. Check that it’s compatible with the exact model and that you have the necessary accessories.
If the energy label gives a figure in kWh/100 cycles, divide it by 100, then multiply it by your estimated number of cycles per year to get an estimate in kWh. Compare figures calculated on the same basis and take into account the programmes you’ll use.
