According to ANSI, the maximum temperature for permanently installed residential spas should not exceed how many degrees Fahrenheit?

The correct maximum temperature for permanently installed residential spas, according to ANSI (American National Standards Institute), is 104 degrees Fahrenheit. This standard is established to ensure the safety and comfort of users while minimizing the risk of overheating, which can lead to health issues such as dehydration, dizziness, and fainting. The 104 degrees limit helps to provide a pleasant user experience without exposing individuals to excessive heat that could be harmful, especially for vulnerable populations such as children, pregnant women, or those with certain medical conditions.

This temperature regulation also emphasizes the importance of responsible spa usage, allowing users to enjoy the benefits of relaxation and hydrotherapy without compromising their safety. Spas operating at or above this temperature should include clear warnings to educate users about potential risks associated with higher temperatures.
