How much does a space heater cost to run in Spain?
Electric space heaters run 500 to 3,000 watts and are 100% resistive — every watt in becomes one watt of heat, no more. That makes them the most expensive way to warm a room over time. A reverse-cycle heat pump (the same unit as a split air conditioner) delivers roughly three times the heat per unit of electricity. Space heaters make sense for quick, occasional warmth in one room; for regular heating they add up fast. Enter the wattage and hours to see the real running cost.

Frequently asked questions
How much does an electric heater cost to run in Spain?
A 2,000 W heater run 4 hours a day costs about €0.38 an hour and roughly €46 a month at an all-in rate near €0.19/kWh. Run longer, and it climbs quickly.
Is a space heater cheaper than central heating?
For a single room briefly, sometimes. But per unit of heat, a reverse-cycle heat pump is around three times cheaper, so for regular use it wins.
