What is the maximum allowable temperature for hot water used by residents?

The maximum allowable temperature for hot water used by residents is set primarily to ensure safety and prevent scalding. A temperature of 110 degrees Fahrenheit strikes a balance between being hot enough for comfortable bathing and handwashing, while significantly reducing the risk of burns, especially for vulnerable populations such as children and the elderly.

At temperatures above this, the risk of scalding increases considerably. For instance, water at 120 degrees Fahrenheit can cause burns in just a matter of minutes, making it too high for regular residential use. Setting the limit at 110 degrees aims to maintain a safe environment for all residents.

While other choices may represent varying hot water standards in different contexts, 110 degrees is widely recognized as the safest maximum limit for hot water in residential settings, aligning with safety regulations and guidelines in many health organizations.
