What a hot tub costs to run in Mallorca

In Mallorca at about 0.22 euros per kWh, held at 38 °C and used three times a week, an Essential 5-seater costs roughly 35 to 45 euros a month in summer and 60 to 80 in winter. A Premium model is 30 to 40 and 50 to 70 thanks to better insulation and the circulation pump, and a Signature 25 to 35 and 45 to 60. The better the series, the more of its price you get back over the years in electricity.

Keep the cover on and in good condition, because most heat is lost from the surface; a cover lifter makes that effortless. Hold the temperature steady rather than reheating from cold, keep the spa out of the wind or behind a windbreak, and set filtration cycles to run at the cheapest hours of your tariff. A spa that is a degree or two cooler in summer, 36 instead of 38, also costs noticeably less.

Yes. A hot tub is designed to run continuously, filtering a few hours a day and topping up heat as needed, and keeping 1,000 litres warm costs far less than heating it from cold every weekend. For a week away, leave it as it is; for a month or more, lower the set temperature to 25 to 30 °C and let the holiday check keep an eye on the water.

A 5-seater holds around 1,150 to 1,400 litres and is changed three or four times a year, so water use is a few thousand litres annually, less than a small lawn. Chemicals are modest once the routine is set: a sanitiser, a calcium control for Mallorca's hard water and a test strip once a week. The starter kit at 160 euros covers the first months, and the UV and ozone upgrade at 590 euros cuts chlorine use after that.
