Swimming Pool Heating Cost Calculator


A heated swimming pool provides year-round enjoyment, but it's essential to budget for the cost of heating it. Our Swimming Pool Heating Cost Calculator helps you estimate the expenses associated with keeping your pool at the desired temperature. In this article, we'll guide you on how to use this calculator effectively.


The cost of heating a swimming pool is based on the volume of the pool, the desired temperature increase, and the energy cost per kilowatt-hour (kWh). The formula can be explained as follows:

Estimated Heating Cost = (Pool Volume in Gallons × Temperature Difference × 8.34) / (Energy Cost per kWh × 1000)

How to Use

Our Swimming Pool Heating Cost Calculator is user-friendly:

  1. Enter the volume of your pool in gallons.
  2. Input the desired pool temperature in degrees Fahrenheit (°F).
  3. Specify the cost of energy per kilowatt-hour (kWh).
  4. Click the "Calculate" button.

The calculator will provide you with an estimated heating cost based on your inputs.


Suppose your pool has a volume of 20,000 gallons, and you want to increase the temperature by 10°F. If the energy cost is $0.15 per kWh, input these values into the calculator. After clicking "Calculate," you'll receive an estimated heating cost for achieving the desired temperature.


  1. What factors affect the cost of heating a swimming pool? Key factors include pool size, desired temperature, energy efficiency of the heating system, and energy costs.
  2. Is the calculator suitable for both residential and commercial pools? Yes, it can be used for various types of pools.
  3. Can I use it for pools heated with different methods, such as gas or solar? Yes, but you'll need to adjust the energy cost accordingly.
  4. Is the calculator accurate for different climates? It provides a general estimate; local climate and pool insulation may affect actual costs.
  5. Does it consider the heating duration? No, it provides a one-time heating cost estimate.
  6. Are there additional maintenance costs for pool heating systems? Yes, regular maintenance and repairs are additional expenses.
  7. Can I use it for both indoor and outdoor pools? Yes, it works for both types.
  8. Is there an optimal pool temperature for energy efficiency? Lower temperatures are more energy-efficient, but it depends on personal preference.
  9. Does the calculator account for heat loss from the pool? It assumes a constant temperature difference; actual heat loss may vary.
  10. What are some energy-efficient ways to heat a swimming pool? Options include solar heating, pool covers, and energy-efficient heat pumps.


Our Swimming Pool Heating Cost Calculator is a valuable tool for anyone considering heating their pool. While this estimate provides a good starting point for budgeting, actual costs may vary based on various factors. Consult with pool professionals and energy providers for more precise estimates and guidance on energy-efficient pool heating options. Use this calculator to plan for comfortable swimming temperatures while keeping energy costs in check.
