If you don’t have an external vent, consider a conventional condenser or heat pump tumble dryer. Unlike vented models, these don’t need to expel air outside, as Que Choisir explains. To compare the two technologies, look at energy use in kWh/100 cycles, the Eco programme duration, and each model’s installation and maintenance requirements. A room without an external vent isn’t necessarily suitable for every appliance.
If there’s no opening to vent damp air outside, compare conventional condenser and heat pump tumble dryers rather than a vented model. Que Choisir distinguishes between these two types by the fact that neither needs a connection to the outside.
If you do laundry frequently, compare the energy use and cycle times of the models you’re considering. ADEME explains that the energy label shows consumption in kWh per 100 reference cycles. This makes it easier to compare appliances on a like-for-like basis.
Not needing an external vent doesn’t mean you can overlook where the appliance will go. Electrolux warns that a room that’s too small may encourage condensation. Check the dimensions and the instructions in the manual against the space you actually have available.
First, make sure the appliance is suitable for use without an external vent. Then compare models that will fit in your room and suit your laundry routine.
| Criterion | What to check | Your needs |
|---|---|---|
| Appliance type | Look for the terms ‘condenser’ or ‘heat pump’. Don’t confuse the possible need to drain condensed water with the air vent required by a vented model. | I don’t have an opening to vent air outside, but I can check how the water extracted from the laundry is collected. |
| Energy use and cycles | Compare the energy rating and kWh/100 cycles shown on the label, as well as the Eco programme duration. If you need a quick programme, check its load limit too. | If I need to dry several loads in a row, cycle duration matters just as much as the energy use shown on the label. |
| Space and temperature | Check the dimensions, the space needed to open the door and the required clearances. Check the temperature range and placement instructions in the model’s manual. | In a small room, I need to be able to position and use the appliance in line with its manual, without assuming that a closed cupboard will be suitable. |
| Capacity | Compare the stated capacity with the loads you actually plan to dry. Check the limits for the programmes you intend to use. | I want to dry my usual loads without assuming that every programme can handle the appliance’s maximum capacity. |
| Water and maintenance | Check how the water tank works and, if you’d prefer direct drainage, whether a kit is compatible with the exact model number. Read the instructions for cleaning the filter and condenser. | I’d like to know where the condensed water will go and what regular maintenance is required. |
If your room can’t accommodate any appliance in line with its manual, air-drying on a clothes horse is another option to consider, depending on the space available and the room’s humidity. If you choose this option, keep an eye out for persistent condensation on surfaces.
A hose for draining condensed water isn’t a substitute for the external air vent required by a vented tumble dryer.
If you don’t have an external vent, first check the type of tumble dryer. Then look separately at the water tank and whether direct drainage is compatible, if that’s what you’d prefer.
The type of appliance alone won’t tell you whether its programmes fit your laundry routine. A quick cycle may also have a different load limit from the appliance’s stated maximum capacity.
Compare the Eco programme duration and, if needed, the quick programme’s duration and load limit on the product details for the models you’re considering.
Electrolux says a room that’s too small may encourage condensation on surfaces. So, being suitable for use without an external vent doesn’t, by itself, mean the appliance is suitable for your chosen location.
Measure the available space, including room to open the door, then check the clearance and placement instructions for the exact model before ordering.
Electrolux warns that a condenser clogged with lint can increase energy use and damage the appliance.
Follow your model’s instructions for cleaning the filter and condenser, including if it has an automatic cleaning system.
These range and model examples can help you identify features to compare; they don’t represent every appliance from each brand.
The WQG24502FR is an example of the features to check in a heat pump tumble dryer.
The brand’s product details let you check energy use, capacity and placement requirements for each model.
The brand offers both conventional condenser tumble dryers and heat pump models.
The TEA525WP is an example of an 8 kg heat pump tumble dryer in the Miele range.
These models are listed as condenser or heat pump tumble dryers for homes without an external vent. Compare their stated capacity and features, then check the manual for each model to make sure it’s suitable for your chosen location.

The heat pump makes this model worth considering if you don’t have an air vent leading outside.
The title lists an 8 kg capacity and a C energy rating. To check whether it suits your room and laundry routine, look at the dimensions, energy use in kWh/100 cycles, Eco programme duration and installation instructions for this model.

This 10 kg heat pump model is worth considering if you dry large loads and don’t have an external vent.
The title lists a D energy rating and a quick-dry programme. Check the load limit for this programme, as well as the dimensions, kWh/100 cycles, Eco programme duration and installation requirements.

This 8 kg model gives you another capacity to consider among heat pump tumble dryers that can be used without an external vent.
The title lists a D energy rating and quick drying. Compare the load limits and durations of the programmes you’ll use, then check the dimensions, kWh/100 cycles and installation instructions.

Listed as a condenser tumble dryer, this 8 kg model is worth considering if you need to dry laundry without venting air outside.
The title mentions propane refrigerant and OptiSense, but doesn’t specify the exact drying technology. Check the technology, dimensions, kWh/100 cycles, programme durations and placement instructions for this model.
No, not if you don’t have a suitable outlet. Que Choisir explains that a vented model expels damp air through a duct to the outside. Instead, consider a conventional condenser or heat pump tumble dryer, provided the room meets its installation requirements.
Whether or not the room has a window isn’t enough to determine if it’s suitable. Electrolux recommends a room that’s spacious and well ventilated, and warns of a risk of condensation in a room that’s too small. Check the manual and placement requirements for the exact model.
Compare the energy rating and energy use in kWh/100 cycles, among other details. ADEME explains that the latter is based on reference cycles. Also consider capacity, Eco programme duration, noise and, for a condenser appliance, condensation efficiency, so you can relate the figures to how you’ll use it.
It depends on how the model collects water. If it uses a tank, you’ll need to empty it as instructed in the manual. Direct drainage may be an option if a compatible kit and suitable water outlet are available. Electrolux describes such a kit for some condenser tumble dryers, so check that it’s compatible with the model you choose.
Follow the model’s manual for cleaning the filter and checking the condenser. Electrolux’s care instructions say to clean the filter after every cycle and warn that a blocked condenser can increase energy use or damage the appliance. How you clean the condenser varies depending on its design, particularly if it has an automatic cleaning system.
