If you have room for a dedicated appliance and dry clothes regularly, a heat pump tumble dryer works without an external vent and uses less electricity than a conventional condenser model, according to UFC-Que Choisir and the European Commission. If you can only install one appliance, a washer-dryer saves space, but its drying capacity is lower than its washing capacity and its cycles can be long. A conventional condenser dryer is another option to consider; compare its energy use and the specifications of the model you’re looking at.
If your kitchen, bathroom or utility cupboard can only fit one appliance, a washer-dryer means you don’t need to find room for a second one. Bear in mind, though, that its drying capacity may be lower than its washing capacity.
If you need to dry several loads at home each week, pay close attention to electricity use per cycle and drying capacity, provided you have room for a dedicated appliance.
If you do several loads in a row and can install a separate tumble dryer, compare programme times and how much laundry it can dry per cycle. Also make sure you can easily access the water tank and the parts that need maintenance.
In a flat without an external vent, first work out whether you can install a dedicated appliance or need to fit washing and drying into a single space.
Consider it: if you have space for a dedicated appliance and regularly dry clothes without an external vent.
Bear in mind: some cycles may take longer than those of a conventional condenser dryer, according to UFC-Que Choisir.
Consider it: if you want a dedicated appliance that doesn’t need a vent and you’re comparing the cycle times of the models available.
Bear in mind: this technology uses more electricity than a heat pump, according to UFC-Que Choisir. Check the energy label for the specific model.
Consider it: if you only have room for one appliance at home.
Bear in mind: drying capacity is lower than washing capacity, and programmes can take a long time, according to UFC-Que Choisir.
| Feature | What to check | Who is it for? |
|---|---|---|
| Available space | Measure the space and allow room for the door to open. For a washer-dryer, compare washing and drying capacities in kg. | If there’s no room for a second appliance, being able to wash and dry in the same place matters more than the size of the drying load; around 29% of consumers would make space their top priority. |
| Electricity use | Compare the energy label and the consumption for the cycle you’ll use. For a two-in-one appliance, check the figures for the wash-and-dry cycle. | If you dry several loads each week, you’ll want to keep an eye on the electricity used per cycle. Energy use would be the top priority for around 29% of consumers. |
| Capacity and cycle time | Check the drying capacity in kg and the duration of the programme you plan to use. | When you have several loads to get through, drying enough laundry without holding up the next load becomes essential; around 24% of consumers would prioritise this. |
| Water and maintenance | Check that the tank and filters are easy to access, and see whether the model can drain water directly by consulting its manual. | If emptying a tank or reaching the filters would be difficult in your home, you’ll want a setup that’s practical for everyday use. Around 18% of consumers would put this convenience first. |
UFC-Que Choisir points out that a washer-dryer’s drying capacity is lower than its washing capacity. After washing a full load, you may need to take some clothes out before starting the drying cycle.
Compare both capacities in kg with the amount of laundry you want to dry in one go.
Not having an external vent doesn’t mean you can ignore water management: water can be collected in a tank or sent down a drain. Whirlpool says that direct drainage depends on the model.
Check the manual for your chosen appliance to see how the tank works, whether direct drainage is supported and which accessories you’ll need.
According to UFC-Que Choisir, a conventional condenser dryer may dry clothes faster than a heat pump model, but it uses more electricity. The European Commission also states that, since 1 July 2025, only tumble dryers using the most efficient heat pump technology may be placed on the EU market. This rule alone does not determine the status of an appliance already on sale.
Compare the energy figures for the specific model and ask the retailer to clarify the status of the appliance they’re offering.
Lint can clog parts of the appliance. Electrolux says that a blocked condenser can increase energy use.
Follow the manual for your model when cleaning the filters and, where applicable, the condenser.
The WQG2450SFR is an example of Bosch’s heat pump tumble dryers designed for a dedicated space.
The RH9V72IXN is an example of an LG 9 kg heat pump tumble dryer.
The FFTBCM118XBFR is an example of a conventional condenser dryer from Whirlpool.
These three standalone appliances offer a solution without an external vent for homes where a separate tumble dryer can be installed. Before choosing, compare their dimensions and water management requirements with the space you have available.

For drying clothes at home with a dedicated appliance that doesn’t need an external vent. The stated capacity is 8 kg. Direct connection to a drain is listed as an option; check the manual for connection requirements and whether a hose is included. Also measure the space and check the duration and energy use of the programmes you’re interested in.

A standalone option if you can set aside space for drying without an external vent. The stated capacity is 8 kg. Check the dimensions, how water is collected or drained, and the duration and energy use of the relevant cycle.

A dedicated appliance to consider if you have enough room to dry clothes without an external vent. Its capacity is listed as 10 kg in the product title and 8 kg in other specifications, so ask the retailer to confirm the drying capacity of the exact model. Also check its dimensions, water management, programme times and energy use.
Yes. A condenser tumble dryer, including a heat pump model, doesn’t need an external air vent, according to UFC-Que Choisir and the European Commission. Depending on the model, condensed water is collected in a tank or sent down a drain. A vented tumble dryer, on the other hand, needs an external outlet.
Not necessarily. Some models can be connected to a drain, while others need their tank emptied when it’s full. Whirlpool says this option varies by model, so check the manual and find out which accessories you’ll need.
Clean the lint filter as often as advised in the manual and follow the instructions for your model’s condenser. Electrolux says that a blocked condenser can increase energy use.
Compare the figures for the cycle you’ll use, not just the energy rating shown. For washer-dryers sold in the European Union, the European Commission says the label includes information such as energy and water use, cycle duration and noise levels. Make sure you distinguish between figures for washing alone and those for a wash-and-dry cycle.
