If you’re wondering how much it costs to heat a swimming pool in Orihuela Costa, the short answer is that it depends on the size of your pool, the heating system used, whether you have a pool cover, and the time of year.
For many villa owners and holidaymakers on the Costa Blanca, a heated pool can extend the swimming season well beyond the summer months. However, heating a pool is often one of the largest reasons for an astronomical electricity bill.

How Expensive Is It to Heat Your Pool?
Heating costs can vary dramatically. Spanish law bans the heating systems of outdoor swimming pools with fossil fuels; so only biomass boilers or solar energy can be used.
A discussion on Alicante Forum highlighted a holidaymaker who received an electricity bill of approximately €250 for a one-week villa stay, largely due to heating a swimming pool before and during their holiday.
The consensus among experienced pool owners was that:
- Initial pool heating is the most expensive phase
- Older electric heaters consume far more electricity
- Maintaining temperature costs much less than raising it
- Pool covers significantly reduce running costs
