Eight months a year, the Irish washing line is theoretical. A tumble dryer costs roughly €1.30–1.80 per load at current rates; a dehumidifier in laundry mode dries the same load overnight for about 6–10 cents — gentler on clothes, with zero condensation soaking your walls. These five have the strongest dedicated laundry performance we compared.

Buying guide: how to choose
Compressor vs desiccant
Compressor models are cheaper to run and ideal for typical Irish indoor temps (15–25°C). Desiccant models work better in cold spaces — garages, unheated rooms under 15°C — but use roughly double the electricity. Most homes want a compressor unit.
Size by litres per day
The headline number (10L, 12L, 20L) is extraction per day under test conditions. Rule of thumb: 10–12L for apartments and bedrooms, 20L for a 3-bed house with drying laundry, 25L+ for big or very damp homes.
Running costs at Irish rates
A modern 12L compressor unit draws ~160 W: about 5–6 cents per hour. Run 8 hours daily and you spend roughly €12–15 a month — usually less than the heating energy wasted evaporating damp air, which is why a dehumidifier can lower total bills.
Laundry mode is the killer feature
If you dry clothes indoors (most of Ireland, most of the year), laundry mode pays for the machine: a good unit dries a load overnight for ~6 cents of electricity versus ~€1.50+ per tumble-dryer cycle, and without the condensation hitting your walls.
Frequently asked questions
Can I dry clothes with a dehumidifier?
Absolutely — it's the cheapest indoor drying method in Ireland. Put the airer in a small closed room with the unit on laundry mode and a typical load dries in 6–10 hours for under 10 cents, with no window condensation.
How much does a dehumidifier cost to run in Ireland?
A 12L compressor model at ~160 W costs about 5–6 cents per hour at typical rates. Eight hours a day works out around €12–15 per month. Desiccant models cost roughly double — but heat the room as a side effect.
Why is my house so damp in winter?
Cold external walls + sealed windows + indoor moisture (cooking, showers, breathing, drying clothes adds ~10L/day for a family) = condensation. Modern retrofits make houses airtight without adding ventilation. A dehumidifier removes that moisture before it hits the glass.
