How much does a dehumidifier cost to run in Spain?
Most home dehumidifiers use 150 to 700 watts. On the damp Spanish coast they earn their keep in both seasons: drier air feels warmer in winter and fresher in summer, and pulling humidity out lets you run heating or cooling a little lower for the same comfort. Because they don't need to run around the clock, short scheduled bursts usually do the job. Enter the wattage and hours to see the running cost per hour, day, month and year.
