With no external air vent, rule out vented tumble dryers: according to Que Choisir, condenser models, particularly heat pump dryers, don’t need this connection. For a new domestic tumble dryer placed on the EU market since 1 July 2025, the European Commission says that only heat pump technology is permitted. Then check the available space, how water is handled, the capacity and cycle times of the model you’re considering.
Who is this choice for?
Homes without an external vent
If the room can’t vent air outdoors, look for a condenser tumble dryer. You’ll also need to decide what to do with the collected water: empty the tank or use a drain connection that’s compatible with the model and your home.
Homes that dry laundry frequently
If you use the dryer often, it’s worth comparing energy consumption with cycle times. According to Que Choisir, heat pump models use less energy than conventional condenser dryers, but they can take longer to dry clothes.
Homes with large loads or tight time constraints
Compare the capacity that suits your loads, programme times and maintenance requirements. A larger capacity alone won’t tell you how long your usual load will take to dry.
What should you consider?
First, choose a solution that works without an external air vent. Then check that each model suits your room and laundry routine.
Heat pump condenser dryer
Worth considering: for a new purchase without an external vent, especially if you use your tumble dryer frequently.
The trade-off: according to Que Choisir, it uses less energy than a conventional condenser dryer, but cycles can take longer.
Conventional condenser dryer
Worth considering: for a model that’s already in circulation or being sold second-hand, once you’ve checked its status.
The trade-off: it doesn’t need an external vent, but Que Choisir says it uses more energy. EU rules in force since 1 July 2025 mean it can’t be treated as a like-for-like new alternative to a heat pump model.
Air-drying without an appliance
Worth considering: if you have the space and time to dry your laundry at home.
The trade-off: make sure this approach also works for large loads and clothes you need in a hurry.

What to check |
Who this matters to |
| Installation and water |
Check the condenser type, dimensions and installation requirements in the manual. Find out whether water collects in a tank or drains away through a compatible connection. |
If my room doesn’t have an external vent, I first need to know whether I can fit the appliance and deal with the condensed water. Around 42% of consumers in this group would make compatibility their top priority. |
| Energy consumption |
Compare energy use in kWh/100 cycles using current product information, as well as the length of the programme that suits your needs. |
If I dry laundry often, energy use is an important factor, even though a longer cycle won’t always suit me. This would be the main consideration for around 33% of consumers in this group. |
| Loads and routine |
Check the capacity of the programme you’ll use, published cycle times, and how often you’ll need to clean the appliance and empty the tank. |
With large loads or little time between uses, I need a suitable capacity and cycle length, without overlooking maintenance. This would be the top priority for around 25% of consumers in this group. |
Mistakes to avoid
-
Choosing a vented tumble dryer for a room without an external vent
According to Que Choisir, this type of appliance needs an opening to the outside or an air vent hose, so it won’t work in a room without an external vent.
Check the drying technology before comparing programmes, then read the installation requirements for the model you choose.
-
Assuming direct drainage is included as standard
A condenser tumble dryer may collect water in a tank. Connecting it to a drain depends on the model, the compatible hose or kit, and the layout of your home.
Before ordering, check where the tank is located, which accessories are included and what the connection instructions say.
Electrolux lists the compatible direct-drain kit for the EDHF5841EC as an optional accessory.
-
Comparing an old A+++ rating directly with an A–G rating
These ratings come from different energy-labelling scales. The European Commission says that the new energy-labelling requirements for tumble dryers have applied since 1 July 2025.
To compare models, check their energy use in kWh/100 cycles, capacity and cycle times in the current product information.
-
Choosing based only on the stated capacity
The kilogram rating alone won’t tell you how long a programme takes, how the appliance performs with a partial load or what maintenance is needed between loads.
Compare the capacity with your usual loads, and check the programmes, cycle times and maintenance requirements for the model.
Brands to consider
Bosch
The range includes heat pump tumble dryers, with features varying by model.
- Bosch lists the WQG2450SFR with a 9 kg capacity, a half-load option, a water drain hose and a self-cleaning condenser.
- The hose may not be connectable to a drain in your home, so check the manual and the proposed location.
Electrolux
Some condenser and heat pump models may suit a room without an external vent, subject to the requirements of the individual appliance.
- Electrolux describes the EDHF5841EC as an 8 kg model with a water collection tank and states that it operates in temperatures from 5 °C to 35 °C.
- Its compatible direct-drain kit is optional. This temperature range and compatibility may not apply to other models.
Miele
The French range includes 8 kg and 9 kg T1 heat pump tumble dryers, with features varying by model.
- Miele offers T1 models with capacities of 8 kg and 9 kg, making it easier to compare options with the capacity you need for your laundry.
- Check the features of your chosen model and the instructions for the condensed-water tank or drain hose.
Beko
Beko manuals can help you check the drainage options and installation requirements for a specific model.
- The D34H28393A manual says that water from the tank can be drained directly using the hose provided.
- Read the manual for the model you’re considering to check its installation and clearance requirements. Information for a different model isn’t enough.

Frequently asked questions
Can you install a tumble dryer without an opening to the outside?
Yes. According to Que Choisir and the European Commission, condenser tumble dryers, including heat pump models, don’t need an external air vent. However, check that the manual allows the appliance to be installed in your chosen location and that you can deal with the condensed water.
Does a condenser tumble dryer need a water drain?
No. The water can collect in a tank that you empty. Some models can drain directly; check that the connection is compatible and that the right hose or kit is included.
What should you check in the room before installation?
Check the dimensions, clearance, electricity supply, permitted temperature and access to the tank or drain in the manual for the exact model. For example, Electrolux states that the EDHF5841EC operates between 5 °C and 35 °C. This range shouldn’t be assumed to apply to another appliance.
How do you compare the energy use of two tumble dryers?
Compare their stated energy use in kWh/100 cycles and the programme times for loads like yours. EU energy labelling changed on 1 July 2025, so don’t treat an old A+++ rating and a rating on the A–G scale as directly equivalent.
Can you still buy a new conventional condenser tumble dryer?
For new domestic tumble dryers placed on the EU market since 1 July 2025, the European Commission says that only heat pump technology is permitted. If a listing offers a conventional condenser model, check its status and age before treating it as a current new product.
