Calculating Pool Heating Costs
Now that you understand how to create an energy efficient pool environment and have
reviewed the various heating options available, you can easily estimate the costs of heating your
pool. Section III gives you a step-by-step procedure so that you can determine what it will cost
you to heat your pool with various fuels and different pool heating technologies.
Energy costs change as a result of supply and demand dynamics. Regardless, they have a
tendency to go up or down at the same times since energy costs are often interrelated. Therefore,
while the costs of energy may change, their relationships remain quite consistent. For comparative
purposes, these calculating formulas are not affected by the day-to-day fluctuations in energy
The following page illustrates the cost of various energy methods to heat pools (Illustration
14) on March 1, 1988. The following page is an update to the study made on November 22,
2000. This energy study compares energy costs in Minnesota and Florida. All of the assumptions
and formulas have been included in the following pages. Local energy conditions may vary and
can affect your own individual situation. The study provides a method for comparison.
