Without an external air outlet, consider a condenser tumble dryer, either a standard model or one with a heat pump, rather than a vented model. If you dry laundry frequently, compare the energy consumption of the models you’re considering. If you do laundry less often or don’t have a suitable space, drying without an appliance is still an option. In every case, check the space available, the installation requirements and how the condensed water is handled.
You need an appliance that doesn’t expel moist air outside through a duct. According to Que Choisir, condenser tumble dryers, including heat pump models, can meet this requirement. However, always check the manual to make sure the room is suitable.
If you use your tumble dryer regularly, it’s worth comparing the electricity consumption of different models. ADEME says this is given in kWh per 100 standard cycles, making it a more useful measure than assumptions based on the technology alone.
Whether you’re placing it next to a washing machine or in a narrow space, check the dimensions, door clearance and noise level against the room you have. If you plan to stack the appliances, the instructions and a stacking kit compatible with both models are just as important as their width.
First rule out appliances that need an external air vent, then compare the remaining models with how often you’ll use them and the space available.
Consider this if: you want a tumble dryer without an external vent and place particular importance on the length of the available programmes.
Bear in mind: Whirlpool describes its standard models as using more electricity than its heat pump models. Check the figures for the appliances you’re comparing.
Consider this if: you dry laundry regularly and energy consumption is an important factor for you.
Bear in mind: not needing an external vent doesn’t mean you can ignore the condensed water or the maintenance specified in the manual.
Keep this option if: you don’t often have laundry to dry, or you don’t have a space that meets the installation instructions for the appliance you’re considering.
Bear in mind: this option won’t give you the programmes or drying capacity of a tumble dryer.
| Factor | What to check | Who this matters to |
|---|---|---|
| Installation without an air outlet | Choose a condenser model and check the manual’s ventilation requirements, along with the condensate tank or drain options. | I don’t have an opening or duct to the outside, and need to be able to install the appliance in my room. Around 36% of consumers would prioritise this installation compatibility. |
| Electricity and fabrics | Compare consumption in kWh/100 cycles and the programmes suited to the fabrics you dry. | I do laundry frequently and want to compare energy consumption without overlooking the programmes my clothes need. This would be a priority for around 29% of consumers. |
| Capacity and space | Match the capacity in kg to your washing machine’s capacity. Also check the depth, door clearance and, if needed, the stacking kit. | In my limited space, the appliance needs to fit my laundry loads and the space available. This would be the main requirement for around 21% of consumers. |
| Cycle duration | Check the length of the Eco programme and the programmes you plan to use, model by model. | Sometimes I need my laundry ready quickly, so programme duration affects my choice. Around 14% of consumers would make it their top priority. |
Heat pump tumble dryers also produce condensed water. Depending on the model, it’s collected in a tank or can be directed to a drain. So, no external air outlet doesn’t mean you won’t need to manage the water.
Before choosing, check how the water is collected, whether there’s a full-tank alert and the requirements for using a drain kit.
A letter on its own doesn’t tell you the exact energy consumption, cycle duration or whether the appliance is suitable for your room. ADEME recommends checking the consumption in kWh per 100 standard cycles.
Compare the consumption figures for the models you’re considering, then look at their capacities, noise levels and programme durations.
The stated capacity tells you nothing about the appliance’s depth, door clearance or whether the tumble dryer can be placed on your existing washing machine.
Measure the space with the door open. If you plan to stack the appliances, check the manuals to confirm that the two models and the stacking kit are compatible.
If the appliance isn’t connected to a drain, you’ll need to empty the tank. Filter and condenser care instructions vary depending on the technology and model.
Make sure the tank and filters will be accessible in your chosen spot, then follow the maintenance instructions in the manual.
These ranges offer features worth comparing. The installation options mentioned apply to specific models, not every appliance from a particular brand.
Bosch’s heat pump tumble dryer range lets you compare the stated capacity and noise level of each model.
The GentleCare 600 EW6HI5829SB provides specifications for a heat pump condenser tumble dryer.
The product information for the TEA525WP 8 kg Active describes several possible installation options for this heat pump model.
Whirlpool offers standard condenser tumble dryers as well as heat pump models. Both are options to consider when you don’t have an external air outlet.
These condenser models, several of which use heat pump technology, give you the chance to compare 8 kg and 10 kg capacities for drying laundry without an external air outlet. You’ll still need to check that the chosen model will fit your home and how it handles condensed water.

Worth considering if you’re looking for an 8 kg heat pump model without an external air outlet. The product title gives it a C energy rating. Before deciding where to put it, check its consumption in kWh/100 cycles, dimensions and how it handles condensed water.

Worth considering if an 8 kg capacity suits your laundry loads and you’re looking for a condenser appliance. The product name mentions propane refrigerant, but that alone doesn’t establish the heating technology. Check this, the energy consumption and the model’s installation instructions.

Its stated 10 kg capacity is worth comparing with your washing machine and the loads you usually dry. The product title gives it a D energy rating. Also check its dimensions, consumption in kWh/100 cycles and how it collects condensed water.

This 8 kg heat pump model is worth considering if that capacity suits your laundry loads. The product title gives it a D energy rating. Before choosing it, compare its consumption in kWh/100 cycles and check the noise level, dimensions and how it handles condensed water.
Yes. According to Que Choisir, a condenser tumble dryer, including a heat pump model, can be installed without an air outlet to the outside. A vented model, on the other hand, needs an opening or duct. For a condenser appliance, always check the manual for requirements relating to the room and the collected water.
No. Depending on the model, the water can be collected in a tank that you empty; a direct drain connection is another option when supported. Check the tank and connection requirements. For example, Electrolux lists a 5.32 L tank and an optional drain kit for the GentleCare 600 EW6HI5829SB.
Choose a drying capacity that suits the loads you usually take out of your washing machine. Miele recommends matching the maximum load where possible. Also check the capacity allowed for the programmes and fabrics you’ll actually use.
No. Similar widths aren’t enough to confirm that the appliances can be stacked safely. Miele lists this as an option for its TEA525WP, but you’ll need to check the manuals to make sure the washing machine and stacking kit are compatible.
