If you’re buying a new tumble dryer for a home without an external vent, start by looking at heat pump condenser models. UFC-Que Choisir states that they don’t need a duct to the outside, and the European Commission says that household tumble dryers placed on the EU market since 1 July 2025 must use this technology. Your choice then depends on the space you actually have, the requirements in the manual and how the appliance handles condensate. If you can’t install an appliance, you could still use an indoor drying rack in a sufficiently large, well-ventilated room, or one with suitable mechanical ventilation, as recommended by ADEME.
If a drying rack would take up permanent space in your living area, a condenser tumble dryer lets you dry clothes without a duct to the outside, according to UFC-Que Choisir. You’ll still need to find a spot that meets the requirements in the manual.
The width of the space isn’t the only thing to consider. Check that the appliance can be moved into position, that its door can open fully and that there’s enough clearance around it. If you’re stacking appliances, check that the two models and the stacking kit are compatible.
A heat pump dryer does away with the need for an external duct, but programme times and maintenance are important in day-to-day use. Beko says its heat pump models generally take longer to run and need more frequent maintenance than other tumble dryers, so check these details against the manual for the model you’re considering.
First, work out whether you can install an appliance at home. Then compare its capacity and any day-to-day requirements. A drying rack is another option when space is limited, but it also needs a suitable room.
Worth considering: when buying a new tumble dryer, if you can install one without an external duct.
Bear in mind: check programme times and follow the maintenance instructions for your model.
Worth considering: particularly if you already own an appliance that’s suitable for the space.
Limitation: the European Commission says that household tumble dryers newly placed on the EU market since 1 July 2025 must use heat pump technology.
Worth considering: if there’s no suitable space for an appliance but you do have a suitable room for drying clothes.
Drawback: your clothes take up room while they dry and release moisture into the air indoors, according to ADEME.
| Factor | What to check | What I need |
|---|---|---|
| External vent | Check the appliance’s technology. According to UFC-Que Choisir, condenser dryers don’t need an external duct, unlike vented models. Check the installation requirements for your model. | I don’t have an external opening or a suitable duct, so a vented model isn’t suitable for this installation. |
| Space | Measure the appliance, the route to its intended position and the space needed with the door open. Check the clearance and room requirements in the manual. For a stacked installation, make sure the kit and both appliances are compatible. | The appliance needs to fit without blocking access to the room or assuming that my washing machine can support any tumble dryer. |
| Capacity and cycles | Compare the drying capacity with your usual laundry loads and your washing machine. Check the length of the programmes you expect to use. | I want to be able to wash and dry clothes without routinely having to split a load across several cycles. |
| Energy use | Compare energy-use information for similar programmes and capacities. The European Commission says the new tumble dryer energy label came into effect on 1 July 2025, so don’t compare an old rating directly with a new one. | If I use my tumble dryer often, I want to compare the stated electricity use on a like-for-like basis rather than relying on the letter on the label alone. |
| Condensate | Check how the model collects water. UFC-Que Choisir describes models with either a tank to empty or a connection to the waste pipe; check the manual to confirm what connections are needed. | An emptyable tank may suit me; for a direct drain connection, I’ll need a compatible installation. |
| Air-drying | For an indoor drying rack, ADEME recommends a large, well-ventilated room or one with mechanical ventilation. Keep air inlets and vents clear. | If I keep using a drying rack, I’ll need to set aside a suitable room while the clothes dry. |
A vented tumble dryer needs to send moist air outside. UFC-Que Choisir distinguishes these from condenser models, which collect the water removed from your clothes.
If you don’t have an opening or a suitable duct, rule out a vented model and check the installation instructions for a condenser dryer.
The European Commission says a new label has applied to the relevant tumble dryers since 1 July 2025. A rating on the old scale doesn’t directly correspond to a rating on the new one.
When comparing models, use energy-use information for similar programmes and capacities.
A kit designed for one particular setup won’t automatically fit a different washing machine. Bosch, for example, specifies that one of its kits is for washing machines more than 55 cm deep.
Note down the model numbers and dimensions of both appliances, then confirm that the kit is compatible with that combination.
You’ll also need to factor in the cost of a compatible stacking kit.
ADEME describes air-drying laundry as a major source of moisture indoors.
Choose a large, well-ventilated room or one with mechanical ventilation, and don’t block any air inlets or vents.
These brand examples can help you explore product ranges and accessories, but you should always check installation compatibility against the exact models.
Bosch offers stacking accessories for some washing machine and tumble dryer combinations.
Beko offers both heat pump tumble dryers and washer-dryers, two options to consider when space is limited.
Miele offers stacking kits for some setups, as well as a range of spare parts for tumble dryers.
These heat pump models are worth considering if you’re looking for a tumble dryer that doesn’t need an external duct. Before choosing, check each model against the space you have, its manual and how it handles condensate.

Consider this model if you want to dry clothes without installing an external duct. It has a stated capacity of 8 kg, and the product title gives it an energy rating of C. Check the manual for dimensions, clearance, room requirements and any requirements for a direct connection to the waste pipe.

Its stated capacity of 8 kg is worth comparing with the loads you usually dry; the product title gives it an energy rating of D. Check the manual for dimensions, clearance, room ventilation and how condensate is collected or drained.

This model is worth considering for machine drying without an external duct; the product title gives it an energy rating of D. Check the capacity of this variant before comparing it with your usual loads: information linked to the model number varies between 8 and 10 kg. Also check the manual for dimensions, installation requirements and condensate handling.
Yes. A condenser model, particularly a heat pump dryer, doesn’t need an external duct, according to UFC-Que Choisir. You’ll still need to follow the manual’s requirements for positioning, power supply and collecting or draining water.
No, not without a suitable opening or duct. As UFC-Que Choisir explains, this type of appliance vents moist air outside. Don’t confuse it with a condenser model, which collects the water removed from your clothes.
First, check whether it’s a new appliance being placed on the EU market, older stock or second-hand. The European Commission says that, since 1 July 2025, new household tumble dryers placed on the market must use heat pump technology. This doesn’t mean you need to replace an appliance you already own.
No. Make sure the two models and the stacking kit are compatible. For example, Bosch specifies that one of its kits is for washing machines more than 55 cm deep; that measurement doesn’t apply to all kits.
If possible, use a large, well-ventilated room or one with mechanical ventilation. ADEME points out that air-drying laundry releases a lot of moisture into the air indoors, and recommends keeping air inlets and ventilation vents clear.
