dehumidifier kwh cost
Watts × hours × your €/kWh. Why IgroCasa does not bake in a tariff, and how to use the calculator.

Use is linear: nameplate watts (or, better, a plug meter) times hours, times what you pay. “About €30 a month on average” is marketing without assumptions.
Calculate kWh and euros from your numbersBecause it goes stale in weeks. The right number is the one on your bill.

Dehumidifier: when it actually helps (and when it is wasted money)
Honest criteria for whether a compressor dehumidifier is the right tool. No ranking of untested models.
Dehumidifier, extractor or MVHR: what you actually need
A method comparison, not a brand roundup: when to extract vapour at source, when to dry room air, when continuous ventilation is the job. No model rankings.
Indoor laundry: how much moisture it adds (and what to do)
A full wash can put litres of water into the air. When to air, when to dehumidify, when to move the rack.
