Dehumidifier vs Tumble Dryer: Which Should You Buy?
If you dry laundry indoors, the real question isn't just speed – it's where the 2–3 litres of water per load ends up. One appliance keeps it in your flat's air, the other locks it in a machine.
Head-to-head comparison
| Dehumidifier | Heat pump dryer | |
|---|---|---|
| Electricity per load (6 kg) | 1.5–2 kWh (300 W × 5–6 h) | 1.5 kWh (0.25 kWh/kg) |
| Upfront cost | €120–250 | €400–700 |
| Drying time | 4–8 hours | 1.5–2.5 hours |
| Fabric care | Very gentle | Good on low heat |
| Extra benefit | Prevents mould year-round | None |
| Space needed | Small, portable | Fixed appliance |
When the dehumidifier wins
- You rent and can't install a dryer
- You already struggle with condensation or damp
- You want one device for laundry + mould prevention
When the dryer wins
- Family-sized laundry volume (5+ loads a week)
- You need clothes ready in under 2 hours
- You have the space and budget for a heat pump model
The hidden math
A dehumidifier that costs €150 and also solves a damp problem replaces two appliances.
A dryer that costs €500 and leaves your walls wet solves exactly one.
FAQ
Is a dehumidifier cheaper to run than a tumble dryer?
Per load they are close: around 1.5–2 kWh for both. But the dehumidifier does double duty against damp and mould, which often tips the balance for flats with condensation problems.
Can they work together?
Yes – many households use a dryer for towels and bedding, and a dehumidifier in the drying room for delicates and winter humidity control.
What about a heated airer?
Heated airers are gentle and quiet but use 3–4 kWh per load – the most expensive option per cycle. Details: heated airer running costs.
