When you come to Florida to vacation, you expect to be able to play and swim in the warm Florida weather!  But, the weather in Florida does not always cooperate.  The average temperatures during the year range from
A Solar pool heater consists of collectors on the roof through which the pool water is pumped.  The sun heats the collector and the heat is transferred to the water then returned to the pool.

Heat from the pool is lost as the heat radiates away from the water.  During the summer, the solar system is able to replace the heat as quickly as it is lost.  During cooler weather the heat loss can be very quick. The temperature of the pool can drop 40 degrees overnight!  To stop the heat loss a solar blanket is placed on the pool to hold the heat in.

The roof top solar system can  maintain heat up to 83 degrees on a sunny day.  But getting there is a slow process.  So, we have a natural gas heater in series with the solar system to provide heat at a faster rate.  Many other vacation rentals charge $25 or more per day for gas generated heat.  Our charge for gas pool heat is $15 per day.  The third vital component for pool heat is the use of a solar blanket to keep the heat in the pool!  We have provided a solar blanket which retains the heat.  If left off, over-night the pool temperature may drop anywhere from 20 to 50 degrees depending upon weather conditions. If bitter cold weather blows down from the north, not many people would want to venture out to swim, and it would not be practical to attempt to heat a pool when the temperature outdoors is in the 40 degree range!  Even if we tried, the solar and gas heater on the pool probably would not raise the temperature enough to make it comfortable. They simply are not designed to produce that much heat.
Generally, if the night time low goes below 45 degrees and the following daytime high temperature does not reach 65 degrees, the design of the two systems may not be able to economically raise temperatures into the comfortable swimming category.
It would take hours of applying heat and it would be lost almost as fast as it was added.

We strongly urge our guests after using the pool to re-cover the pool with the solar blanket to prevent heat loss.  Our goal is for you to enjoy 83 degree water everyday of the year...  January is actually Florida’s coldest month and if the area gets hit with a severe winter storm, providing pool heat may become impossible.  For example if the temperature were to drop to the mid-thirty degree level, we could run the pool heater all day long and the water would still be too cold to swim.  Here are the average weather stats for January and February:

THE POOL IS HEATED TO A MAXIMUM TEMPERATURE OF 83 DEGREES.  THIS IS THE TEMPERAURE RECOMMENDED BY THE GAS AND ELECTRIC UTILITIES AND THE POOL SERVICE INDUSTRY. 

IT IS ALSO THE SUMMERTIME TEMPERATURE OF THE ATLANTIC OCEAN AND GULF OF MEXICO ALONG THE COASTAL REAS OF FLORIDA!
