If you dry your laundry indoors, start with a suitable spin cycle and choose a large, well-ventilated room or one with an extractor fan. If you do laundry frequently, a condenser tumble dryer can save you from having an airer taking up space, provided you have room for one and compare its cycle times and energy use. A dehumidifier is better suited to complementing an airer: it doesn’t replace a suitable room for drying laundry.
If your airer takes up space in a living room, bedroom or small bathroom, your choice depends as much on the space available and ventilation as on how long your laundry stays out. The Q-WASH study published by ADEME highlights the moisture released when laundry is air-dried indoors.
If you regularly need to dry clothes, towels and household linen, compare an appliance’s actual drying capacity, programme times, noise levels and energy use.
A washer-dryer can save you from installing two separate appliances, but its drying capacity needs to suit your usual loads. For example, Bosch lists the WDU8H500FF as having a 10 kg washing capacity and a 6 kg drying capacity.
First, decide where your laundry can dry, then check each appliance’s capacity and installation requirements against your usual loads.
| Consideration | What to check | Who it matters to |
|---|---|---|
| Humidity in the room | For an airer, choose a large, well-ventilated room or one with an extractor, as recommended by the Q-WASH study published by ADEME. If you add a dehumidifier, also check the recommended room size and how its water tank is managed. | If your airer is in a living space, limiting the extra humidity it creates matters more than speed: around 36% of consumers put this concern first. |
| How often you do laundry | Match the tumble dryer’s capacity to your washed loads and check the eco programme time for the stated load. Also check its dimensions before deciding on a dedicated appliance. | If you do laundry frequently, waiting for an airer to become free can make it harder to get through successive loads; around 29% of consumers prioritise drying time. |
| Electricity use | Compare tumble dryer energy use on the same label basis. For a dehumidifier, take its power rating and operating hours into account, as explained by Rowenta. | If you need to dry laundry frequently, the energy use of the appliance matters when choosing one; this is the top priority for around 21% of consumers. |
| Available space | Measure the space, access route and door clearance. For a washer-dryer, distinguish between its washing and drying capacities. | In a home with room for just one appliance, keeping a usable space takes priority over other factors for around 14% of consumers. |
A vented model releases moist air outside and needs a suitable duct. A condenser model collects the moisture removed from your laundry without needing an external air vent, according to the European Commission.
If your home doesn’t have a suitable outlet, compare condenser models, then check their dimensions and how the water is collected or drained.
A full wash load may be larger than the same appliance’s drying capacity. For example, Bosch lists the WDU8H500FF as having a 10 kg washing capacity but a 6 kg drying capacity.
Compare both capacities with your usual load; if it exceeds the drying capacity, you’ll need to remove some of the laundry.
For laundry air-dried indoors, the Q-WASH study published by ADEME recommends a large, well-ventilated room or one with an extractor. A dehumidifier’s stated capacity depends on the model and its operating conditions.
Think of the appliance as an addition to your airer, and check its tank, any drainage options and noise level for the intended location.
Running it uses electricity, depending on its power rating and how long it is switched on.
An older product sheet showing annual energy use cannot be directly compared with one using a different energy-label basis. For example, the figures published by Beko for the D3H18C01W are specific to that model and its labelling.
Before choosing between two tumble dryers, check that their energy use is given in the same units and under comparable conditions.
Bosch offers washing machines, washer-dryers and heat pump tumble dryers, which you can compare based on the space available.
The T1 range of heat pump tumble dryers may be worth considering if you’re looking for a dedicated appliance and want to compare its programmes and installation options.
Compare its tumble dryers model by model, particularly if cycle times, noise levels and filter maintenance are important to you.
Its dehumidifiers are worth considering as an addition to an airer in a room suited to indoor drying.
These two heat pump models are suited to homes with space for a dedicated tumble dryer, helping you manage regular laundry loads without relying solely on an airer.

Worth considering if you have space for a dedicated tumble dryer and want to dry loads of up to the stated 8 kg capacity.
The model name indicates a heat pump and energy rating C. Before buying, check the space needed for installation, as well as the eco programme time and energy use for this variant.

Worth considering for regular laundry loads if you want a dedicated appliance, provided it’s suitable for the room where you plan to install it.
The model name indicates a heat pump and energy rating D. Check its dimensions, noise level, water collection system and eco programme details for this variant.
Choose a large, well-ventilated room or one with a mechanical ventilation extractor vent. These are the options recommended for air-drying in the Q-WASH study published by ADEME; there’s no need to alter your ventilation system.
No. According to the European Commission, a condenser tumble dryer doesn’t need to vent moist air through an external duct. However, check how your chosen model collects water or whether it can be connected to a drain.
For the models you’re considering, compare capacity, energy use on the same basis, eco programme time and noise level. If space or connections are limited, also check the dimensions and how water is collected.
Not necessarily: washing and drying capacities can differ. Bosch lists the WDU8H500FF as having a 10 kg washing capacity and a 6 kg drying capacity; compare both figures for the model you’re considering before planning to dry a load without removing any laundry.
Multiply its power rating in kW by its operating hours to calculate its theoretical energy use in kWh, as explained by Rowenta. For your own use, actual running time matters just as much as the stated power rating.
