What temperature should I set my pool heater to?

The optimal pool temperature varies by use: 78°F-82°F for recreational swimming, 80°F-84°F for children and seniors, 77°F-81°F for athletic swimming, and 84°F-88°F for therapy. Spas are typically 100°F-104°F.

The ideal temperature for your pool heater largely depends on personal preference and the intended use of the pool. However, some general guidelines are:

  1. Recreational Swimming: Most find temperatures between 78°F to 82°F (25.5°C to 27.7°C) comfortable for regular swimming.

  2. Children and Seniors: They often prefer slightly warmer water, around 80°F to 84°F (26.6°C to 28.8°C).

  3. Athletic or Lap Swimming: Cooler water is often favored for vigorous exercise, around 77°F to 81°F (25°C to 27.2°C).

  4. Therapeutic Uses: Pools used for therapy or relaxation might be warmer, between 84°F to 88°F (28.8°C to 31.1°C).

  5. Spas and Hot Tubs: Typically set between 100°F to 104°F (37.7°C to 40°C).

Remember, continuously maintaining very high temperatures can increase operational costs and potentially wear out the heater faster.
