ADVICE & TIPS

Unlike pool heating, which runs practically non-stop all season, a counter-current jet is an appliance that only runs while you are actually swimming. That fundamentally changes how to look at its operating costs.

The power input of a counter-current jet ranges roughly from 400 W on entry models to about 1,250 W on the most powerful variants — and thanks to smooth power control (instead of fixed on/off), the motor runs only at the percentage of power you set. Half an hour of swimming at medium power thus means consumption comparable to running a common kitchen appliance for the same time — a negligible amount per session, depending on your electricity tariff and chosen intensity.

Heating the pool water by one degree Celsius in a common garden pool consumes on the order of tens of kilowatt-hours — and the heat also escapes continuously, so heating runs practically the whole season. A counter-current jet, by contrast, consumes energy only at the moment it is switched on and actually used. Over a season of ordinary recreational use (say 3–4 times a week for 20–30 minutes), we are therefore talking about operating costs on the order of tens, not hundreds of euros.

The three main variables are: the chosen intensity level (lower levels save energy even during longer swims), the total operating time per week, and the power class of the unit — higher models have a higher maximum input, but you normally don’t use them at 100% for the whole swim. Practical tip: for ordinary recreation and playing with children, lower intensity levels are enough even on more powerful models, which keeps consumption low.

With the battery-powered JetSwim X range, the electricity cost is practically irrelevant — the unit just charges between uses, which costs a fraction of running the mains variant. The trade-off is a limited operating time per charge (2.5 to 10 hours depending on the model), after which the unit needs to be recharged.

Running a counter-current jet is a cheap item in a household budget compared to heating the pool — consumption is measured in single kilowatt-hours per training session, not in tens as with water heating. You can find the exact consumption of individual models on the Specifications page.
