You winterize a conventional pool for the winter and do not use it for several months. However, there is a way to swim outdoors all year round — a swim spa pool with a counter-current system. We explain why it works even in freezing weather and how to operate it economically.
Why a swim spa works even in winter
Year-round operation is made possible by a combination of three things: the insulated shell of the swim spa, an insulated thermal cover and powerful heating. A heat pump is ideal, keeping the water at a comfortable temperature even during freezing weather while using little energy. You can swim against the current and relax while snow falls around you.
How to operate a year-round pool economically
- High-quality insulation — the basis for low heat loss.
- Covering — whenever you are not using the swim spa, cover it; the thermal cover retains heat.
- Heat pump — heats the water considerably more economically than a direct electric heater.
- Stable temperature — maintaining the temperature is more economical than reheating the water each time.
Swimming regardless of the length of your garden
The counter-current system creates a continuous flow of water that allows you to swim in place — you do not need a long pool. A year-round swim spa therefore fits even on a smaller plot. We discuss how to choose the right counter-current performance in our article on pools with counter-current systems.
