How much does an electric shower cost to run in Spain?
An instantaneous electric shower heats water as it flows, so it draws a huge 7,500 to 10,500 watts — but only for the few minutes you're under it. It's far more common in the UK than in Spain, where most homes use a tank (termo) or gas, but where one is fitted the per-minute draw is high and total cost depends entirely on shower length. Set the hours to the combined daily shower time across the household.

Frequently asked questions
How much does an electric shower cost to run in Spain?
About €0.29 for a 10-minute shower at 9 kW and an all-in rate near €0.19/kWh. High power, but short runtime keeps the daily total modest.
Is an electric shower cheaper than a tank water heater?
It only heats water on demand, so it wastes no standby heat — but a well-insulated tank heated off-peak can be cheaper overall. It depends on usage and tariff.
