Solar pool heating is something that more people are considering, especially in Florida where sunshine is available year-round. The abundance of sun makes this region a perfect candidate for this sustainable and renewable energy source. Even after inclement weather, several sunny days in a row will bring your pool back up to a comfortable bathing temperature. Why is this source better than a heat pump or gas heater? The main aspect is the cost of energy. The best thing about solar heating is that it is the most economical way to heat your swimming pool because the heat from the sun is free.
