If you don’t have an opening or duct to the outside, rule out vented tumble dryers. According to UFC-Que Choisir, a condenser dryer can be installed without an external connection, including models that use a heat pump. If you dry laundry frequently, compare the energy consumption and capacity of separate appliances. If washing and drying need to fit into one space, consider a washer-dryer, bearing in mind that its drying capacity is lower than its washing capacity.
If you have room for a separate appliance, compare condenser tumble dryers, particularly heat pump models, by their capacity and stated energy consumption. UFC-Que Choisir confirms that a condenser dryer does not need an external connection.
A washer-dryer combines both functions in one machine. Check how much laundry you can actually dry: UFC-Que Choisir notes that its drying capacity is lower than its washing capacity.
Before placing a tumble dryer on top of a washing machine, check the dimensions, appliance compatibility and any kit required by the instructions. For the stacking arrangement described in its WTH8300SFR instructions, Bosch requires a manufacturer-approved connection kit.
First, check that the appliance doesn’t need an external air vent. Then compare your options based on what matters most to you: regular use, cycle times, available space or ease of installation.
| Feature | What to check | Who it matters to |
|---|---|---|
| Energy use for regular drying | Compare the stated energy consumption, capacity in kg and duration of the programme suited to your laundry. | When I do laundry often, I want to keep the energy use of my drying cycles under control; around 33% of consumers are said to prioritise this. |
| Drying time | Check how long the programmes take for the loads and fabrics you usually dry. | If I need to dry several loads in a day, I want to be able to plan them one after another; drying time is said to be the main concern for around 25% of consumers. |
| Available space | Measure the space and compare the separate washing and drying capacities of a washer-dryer. | I only have room for one appliance, but I also need it to dry the amount of laundry I expect to wash; around 25% of consumers are said to prioritise this space constraint. |
| Installation and maintenance | Check the instructions for clearance, condensate management, cleaning and compatible accessories. | For an installation in a tight space, I want to know how to manage the water and access the parts that need cleaning; this is said to be the priority for around 17% of consumers. |
A condenser tumble dryer doesn’t need to vent air outside, but you still need to plan where it will go, how it will be powered and how the condensed water will be managed.
Measure the space and check there’s sufficient access for delivery. Then read the instructions for your chosen model before deciding whether a drain connection or stacking is possible.
Capacity alone isn’t enough to choose between two appliances if their stated energy consumption or programme times matter for your usual laundry.
Compare information for the same types of loads and programmes, taking into account how often you dry laundry.
According to UFC-Que Choisir, a washer-dryer can wash a larger load than it can dry.
Check both capacities on the appliance’s product information and adjust the amount of laundry before starting a drying cycle.
Cleaning them is part of using a tumble dryer. UFC-Que Choisir recommends regularly cleaning the microfilter and condenser.
Follow the cleaning instructions and schedule in your model’s manual, even if it has a condenser-cleaning function.
Bosch offers heat pump tumble dryers. Its WQG2450SFR product information lists a 9 kg capacity and a water drain hose.
Miele offers tumble dryers in different capacities. Its TQ 1000 WP Nova Edition product information lists a 9 kg capacity and SteamCare and WoolDry programmes.
Whirlpool describes its heat pump appliances as condenser tumble dryers. One of its product listings describes an 8 kg model with humidity control.
This selection includes separate heat pump and condenser tumble dryers, as well as a washer-dryer for a single space. Compare each appliance’s capacity with your usual loads, and check the instructions for your intended installation.

Worth considering if you’re looking for a separate 8 kg tumble dryer without an external air vent. The product information lists a heat pump and a C rating. Compare the energy use of the programmes you’re interested in, and check the instructions for condensate management and installation requirements.

This washer-dryer is worth considering when both functions need to fit into one space. It has a stated washing capacity of 11 kg, but a drying capacity of 6 kg. Be prepared to adjust the load before running a complete wash-and-dry cycle, and check the connections and dimensions.
Yes, if it’s a condenser model, including a heat pump dryer. UFC-Que Choisir says it doesn’t need to be connected to the outside. A vented tumble dryer, however, needs a suitable opening or duct.
Check how the model you choose collects water. Some appliances can use a compatible drain connection. Electrolux, for example, describes a kit that drains water into a sink or nearby pipe. Check the instructions and list of approved accessories before planning this connection.
Only if the arrangement follows the manufacturers’ instructions for the appliances concerned. The Bosch WTH8300SFR instructions require a manufacturer-approved connection kit for stacking. Check the dimensions and the kit specified for your exact models, too.
Not necessarily: UFC-Que Choisir notes that its drying capacity is lower than its washing capacity. Compare the two figures listed for the model and reduce the load if it exceeds the drying capacity.
Measure the space and delivery access, then check the model’s instructions for clearance, ventilation, power supply and condensate management. If you’re planning to stack appliances or connect a direct drain, also check that the appliances are compatible and that you have the necessary accessories.
