How much of the year can we expect to swim if we don’t heat our pool?
A lot depends upon how you use your pool and your tolerance for colder temperatures. Residents of northern climates are completely comfortable swimming in 78°F water and this is usually the temperature required for competitive swimming events. On the other hand, Florida residents usually like their pool water a bit warmer; at least 80°F or more. And if you are heating your pool for therapeutic reasons, you will want at least 85°F water and possibly as warm as 90°F.
A Central Florida screened pool will typically be at least 80°F or warmer for about three months and may reach 83–85°F from mid August to early September. Open pools are a bit warmer because the pool surface receives more direct solar energy, and may stay comfortable for an extra month or more.
What are the health benefits of heating my pool?
Doctors and physical therapists regard swimming as a very beneficial form of exercise because it works the entire body without impact stresses on the joints. A heated pool can safeguard your health and contribute to your well-being by allowing you to exercise throughout the year.
And while children love to swim and can often tolerate lower temperatures, pediatricians caution that repeated chilling can make young children more susceptible to respiratory infections. This can also be true for elderly swimmers. A heated pool prevents chilling and problems associated with excessive body heat loss.
