If there’s no accessible drain where you plan to install it, choose a condenser tumble dryer that collects water in a tank, which you’ll need to empty as instructed. A heat pump model is worth considering if energy use matters to you, although its cycles may take longer, as UFC-Que Choisir points out. Only plan to drain water directly if the model you choose and your proposed connection allow it.
If there’s no wastewater connection near your utility room or kitchen, a condenser tumble dryer with a tank can collect the water inside the appliance. You’ll need to empty the tank as instructed for your model. UFC-Que Choisir describes how this works without a connection to an external drain.
If a connection might become available after you rearrange the room, check when buying that your chosen model supports direct drainage. Bosch’s product information and Electrolux’s compatibility guidance show that you can’t assume this is possible based on the brand or drying technology alone.
Not having a drain doesn’t resolve questions about location, electricity or ventilation. If you’re planning to install the dryer in a bathroom, check the manual and have the electrical layout assessed: Promotelec notes that the NF C 15-100 standard defines specific zones in this room.
Start by checking where the water goes, then compare energy use, cycle times and the requirements of the room where you’ll install the appliance.
| What to check | Points to consider | Depending on your needs |
|---|---|---|
| Water collection | Check that the exact model has a tank, how easy it is to access and what the instructions say about emptying it. UFC-Que Choisir explains that a condenser tumble dryer collects water in a tank without connecting to an external drain. | If there’s no drain near the appliance, I can empty a tank instead of arranging a permanent connection. |
| Direct drainage | Check whether the model comes with a hose or supports a compatible kit, then consult the manual for connection and routing instructions. Bosch lists a hose for the WQG2450SFR, but not the WTH83V01FF; Electrolux advises checking whether its kit is compatible. | If a drain becomes available later, I want to know before buying whether this model can be connected to it. |
| Energy use and cycle time | Compare kWh/100 cycles, the Eco programme duration and capacity on a like-for-like basis. According to UFC-Que Choisir, heat pump models use little electricity, while conventional condenser tumble dryers generally dry clothes faster. | If I dry clothes regularly, I may prioritise energy use; if I often need my laundry quickly, I’ll also look at cycle times. |
| Installation location | Check the manual for dimensions, the permitted ambient temperature and electrical requirements. In a bathroom, have the location checked against the electrical zones described by Promotelec. | In a garage, an unheated room or near a shower, I need to check that the location is suitable for the model, even if it has a water collection tank. |
The tank collects condensation without a connection to the wastewater system; it doesn’t mean that a drain hose or kit comes with the appliance.
If you want automatic drainage, check what’s included, which accessories are compatible with the exact model and what its manual says.
On its UK product pages, Bosch lists a water drain hose for the WQG2450SFR, but not for the WTH83V01FF. So the heat pump technology alone doesn’t tell you whether this feature is available.
Check the drainage information for each model, then read its manual for the installation requirements.
A cycle that uses less electricity isn’t necessarily the quickest. UFC-Que Choisir distinguishes between the low energy use of heat pump models and the generally shorter drying times of conventional condenser tumble dryers.
Compare the kWh/100 cycles, Eco programme duration, capacity and noise level for the models you’re considering.
A water collection tank doesn’t remove the need to check the electrical installation. Promotelec explains that the NF C 15-100 standard defines specific zones for bathrooms.
Measure the space and ask a qualified professional to check the location and electrical connection before choosing an appliance for this room.
The drainage options below apply to specific models, not every appliance made by each brand.
Two Bosch heat pump tumble dryers show why you should check the connection for each model.
A drain kit may be useful if you’re considering adding a connection later, provided it’s compatible with your appliance.
The TQ 1000 WP Nova Edition is an example of a model whose product information distinguishes between water collection and drainage.
This condenser tumble dryer is worth considering if there’s no accessible drain where you plan to install it. Before choosing it for this purpose, check its manual to confirm that it collects condensation in a tank and that your planned installation meets its requirements.

If you’re installing the EDH1018CD somewhere without a nearby drain, check its manual to confirm that condensation is collected in a tank. Also check the room temperature requirements and, if you’re considering adding a connection later, the drainage options available for this model.
Yes, as long as the model you choose collects condensation in a tank, so it doesn’t need a permanent connection to the wastewater system. Empty the tank as instructed and check that the location meets the requirements in the appliance manual.
Only if the specific model and any required kit support it. Bosch lists a water drain hose for the WQG2450SFR, but not for the WTH83V01FF; Electrolux advises checking that its kit is compatible with your appliance. Before buying, also check whether you can route the hose where you need it to go.
No. If you’re installing the dryer without a drain, always check that the model collects water in a tank. Heat pump technology also affects the balance between energy use and cycle times: according to UFC-Que Choisir, these appliances use little electricity, while conventional condenser tumble dryers generally dry clothes faster.
You should check the exact location and electrical installation before choosing an appliance. Promotelec notes that the NF C 15-100 standard defines specific zones in bathrooms. Ask a qualified professional to check the location and connection, then consult the appliance manual.
No. Not needing a condensation drain doesn’t replace the need to ventilate your home or follow the appliance’s installation instructions. Make sure your planned installation won’t obstruct existing ventilation and leave the clearances specified in the manual.
