Without an air outlet or duct, rule out vented tumble dryers: according to UFC-Que Choisir, condenser models, including heat pump dryers, work without an external connection. If you have room for a dedicated appliance, compare these two technologies using the specifications for the exact models you’re considering. If you only have space for one appliance, a washer-dryer saves you from having to install a second machine, but its drying capacity is lower than its washing capacity.
If the room has no external opening or suitable duct, a vented tumble dryer isn’t suitable for your setup. UFC-Que Choisir explains that a condenser tumble dryer, whether conventional or heat pump, doesn’t need to be connected to the outside.
A washer-dryer combines washing and drying in a single appliance. To make the most of the space, bear in mind that its drying capacity is lower than its washing capacity, as UFC-Que Choisir points out.
If you have room for a second appliance, you can compare conventional condenser and heat pump tumble dryers by looking at the load you need to dry, the dimensions, cycle times and the energy consumption of the model you’re considering.
Start by checking the available space and connections, then compare drying capacity and the conditions for using the exact model.
| Factor | What to check | My needs |
|---|---|---|
| Installation | Check the drying method and how water is handled: depending on the model, it may collect in a tank or drain away. According to UFC-Que Choisir, condenser tumble dryers, including heat pump models, don’t need to be connected to the outside. | I don’t have a usable duct and want to dry my laundry without creating an air outlet. |
| Space | Measure the width, height, maximum depth, door opening and space needed for connections. A washer-dryer takes up one space; a dedicated tumble dryer needs another. | I want to keep more space in my living room or bathroom. |
| Capacity | Compare the kilograms each appliance can dry, not just wash. UFC-Que Choisir points out that a washer-dryer’s washing and drying capacities differ; for example, Electrolux lists 9 kg for washing and 6 kg for drying for the EW7W3916DA. | I want to dry a full wash load without having to remove some of it, or I need to be able to plan for this step. |
| Cycles and consumption | Check the energy label and the exact model’s cycle times and electricity use, plus water consumption for a washer-dryer. In its test protocol published in January 2026, UFC-Que Choisir notes that most of the washer-dryers tested also use water during drying. | I want the full cycle to fit around my household’s laundry routine and to know which resources it uses. |
| Noise | Compare the stated noise level in dB(A), where you plan to put the appliance and, if available, test results for the exact model. The drying technology alone doesn’t guarantee quiet operation. | The appliance will be near living areas, so I need to be able to choose when to run a cycle. |
A condenser tumble dryer collects the water removed from your laundry. Depending on the model and installation, it goes into a tank or can be directed to a drain.
Check the manual for how water is collected, which accessories are included and how easy it is to access the tank if you need to empty it.
With a washer-dryer rated at 9/6 kg, you can wash a 9 kg load, but the drying capacity is limited to 6 kg. You’ll need to remove some laundry before drying or plan for a different way to manage the load.
Choose based on how much you want to dry in one cycle, and check the load limits for the fabrics you’ll be washing.
Noise and cycle times vary by model. In its test of the Thomson THOM HP8, UFC-Que Choisir noted long cycles and very noisy operation; this doesn’t apply to every appliance.
Check the noise level and programme times, and, if possible, look for test results for the exact model before placing it near your living areas.
An appliance might fit in the space available without leaving enough room to open the door or connect it.
Compare your measurements with the overall dimensions and clearance requirements in the manual for the model you choose.
These brand examples highlight the features to look at; they don’t describe every appliance in each range.
The French product page for the Bosch WQG2450SFR is an example of a dedicated heat pump tumble dryer.
The EW7W3916DA is an example of a washer-dryer for anyone looking to combine two functions in one appliance.
Whirlpool’s French catalogue features condenser and heat pump tumble dryers.
These dedicated condenser and heat pump tumble dryers are options for rooms without an external air outlet. If you only have space for one appliance to wash and dry your laundry, compare their dimensions with those of a washer-dryer.

This dedicated tumble dryer is suitable for an installation without an external air duct. Its stated capacity is 8 kg and its stated energy rating is C. Check the dimensions and required clearances before deciding where to put it.

This condenser model has a stated capacity of 8 kg and doesn’t need an external air duct. Check the available space for the door and connections, as well as how the water is collected.

This 8 kg heat pump tumble dryer could suit a home without an external air outlet. Its stated energy rating is D. Check the energy label for the exact model, along with its dimensions, noise level and programme times, to see if it suits your needs.

This heat pump tumble dryer is suitable for a setup without an external air duct, but check its capacity before buying: the title says 10 kg, while another specification gives 8 kg. Also check the dimensions, noise level and cycle times.
No, not in the setup described. According to UFC-Que Choisir, this type of appliance needs an opening to the outside or a usable duct. A condenser tumble dryer, with or without a heat pump, doesn’t need this connection.
It collects in a tank or, if the model and installation allow, drains away. Check the manual and accessories for the model you’re considering. For example, Bosch lists a water drain hose for the WQG2450SFR.
No: 9 kg is the washing capacity and 6 kg is the drying capacity. To run both stages without removing any laundry, keep the load within the drying capacity for the programme you choose.
Compare the figures on the energy label and product information for the exact model, taking account of the programme and load specified. You can also use the European Commission’s EPREL database to check the declared information for models covered by energy labelling. For a washer-dryer, also look at the water consumption for the wash-and-dry cycle.
