If you don't have an external wall opening or a usable vent hose, you can rule out vented tumble dryers. Instead, you should opt for a condenser model, many of which use heat pump technology. Then, make your choice based on capacity, the space you have available, how often you do laundry, and the level of maintenance you're comfortable with. A heat pump dryer generally uses less energy, but its cycles can be longer than those of a standard condenser model.
To install an appliance without an external opening or hose, you should focus on condenser tumble dryers. Consumer group Que Choisir notes that this technology doesn't require an external connection; however, you should still check the model's placement requirements and ensure you can access the areas needed for maintenance.
If running costs are a concern and you don't mind longer cycles, a heat pump tumble dryer is a good place to start. You should also compare its capacity with that of your washing machine and the amount of laundry you actually dry.
Stacking your dryer on top of your washing machine can free up floor space, but both appliances must be declared compatible for this. Bosch recommends checking the exact model numbers and using a suitable stacking kit.
Choose if: you need to dry laundry without an external hose and want to keep your electricity consumption down.
Bear in mind: cycles can be longer, and you'll need easy access to the filter, water container or drain.
Consider if: having no external vent is essential and drying time is more important to you.
Compare with: this option is generally less energy-efficient than a heat pump model.
Best for: small amounts of laundry when drying time isn't critical.
A word of caution: French environmental agency ADEME points out that air-drying laundry indoors releases a lot of moisture into the air.
| Priority | What to check | Your needs |
|---|---|---|
| Installation without a vent | Choose a condenser model; check the user manual for room requirements, electrical connection, and maintenance access. | I need to install the tumble dryer without an external hose. A condenser model meets this requirement, but I still need to follow the manufacturer's installation instructions. |
| Energy consumption and cycle duration | Compare the A to G energy label, the stated consumption, and the duration of the programmes relevant to your laundry. | I'm looking to reduce energy consumption without disrupting my routine with overly long cycles. The European Commission states that the A to G label has applied to tumble dryers in the EU since 1 July 2025. |
| Capacity and size | Match the capacity in kg to that of your washing machine; also check the depth, porthole opening, and door clearance on the model's product page. | I want to avoid splitting a full wash load or overloading the dryer, while still having an appliance that fits in my space. |
| Easy maintenance | Locate the filter, water collection tank, and the condenser (if it's accessible); follow the cleaning schedule in the manual. | I need to be able to remove lint without moving the appliance. Electrolux recommends cleaning the filter after every cycle on relevant models. |
A condenser tumble dryer doesn't need an external hose, but you still need to consider the room, electrical connection, dimensions, and access for maintenance.
Before you order, check the manual for the exact model and measure the width, depth, door clearance, and porthole opening, as well as access to the filter and water container.
Heat pump dryers generally use less energy, while standard condenser or vented models tend to dry faster. This trade-off is important when you have several loads of washing to get through.
Compare the duration of the Eco programme and small-load programmes on similar models, then choose a solution that fits your laundry routine.
Poor maintenance can affect the appliance's performance. Electrolux states that a clogged condenser can increase energy consumption and damage the appliance.
Choose a model where the maintenance areas are still accessible after installation, and follow the schedule in the manual for cleaning the filter, tank, and condenser.
A condenser clogged with lint can increase energy consumption and lead to malfunctions.
Stacking a tumble dryer on a washing machine frees up space, but the models must be compatible and correctly aligned. Bosch recommends using a suitable fixing kit.
Check both model numbers, the approved kit, the dimensions, and the stability before you buy. Never just place a dryer on top of a washing machine without a device designed for this type of installation.
A compatible stacking kit may be required.

An 8 kg condenser option to consider when you need an installation that works without an external vent.
Check the manual for this specific model to confirm the exact technology, filter and condenser maintenance, and the requirements for ventilation and stacking.
No, that won't work: a vented tumble dryer expels moist air outside and therefore requires an external vent. You should look for a condenser model, either standard or heat pump, and then check its manual for placement requirements.
No. Not having an external hose doesn't mean you can ignore the manufacturer's installation instructions. Whirlpool states that condenser and heat pump appliances must be placed in a well-ventilated room; check the model's manual for clearances, electrical connection, and any other restrictions.
The dryer's capacity should be chosen in relation to your washing machine's capacity and the loads you actually dry. Check the capacity for the relevant programme and don't assume that a compact model can automatically dry a full load of heavy laundry.
At a minimum, you'll need to clean the lint filter after each cycle on relevant models. For an accessible condenser, follow the schedule in the manual; Electrolux notes that a clogged condenser can increase energy consumption and damage the appliance.
Yes, but only if both appliances are compatible with this setup and you use the correct stacking kit. Bosch recommends checking that both models can be stacked and that they are properly aligned once installed.
