iSwim connects seamlessly to your existing pool pump and filter and is controlled by an automatic controller. All you have to do is set your desired pool temperature and let iSwim do the rest.

1. The automatic controller senses when your pool is cooler than you prefer and there is adequate sunlight to heat your pool.
2. Water is diverted from your existing pool pump & filter up to your collector array.
3.  As the water flows through the array, it is heated by the sun and returned to your pool.

This cycle continues until the pool reaches your desired temperature. Once the pool is perfectly heated, the automatic controller stops redirecting water to the array.

You can also cool your pool during warmer months by running the solar system at night. Try that with a conventional heater!
