At what minimum temperature is water classified as hot water?

100 degrees
110 degrees
120 degrees
130 degrees

The correct answer is: 110 degrees

The classification of hot water is typically established based on safety standards and common usage conditions. Water is generally considered hot when it reaches a temperature of 120 degrees Fahrenheit. At this temperature, water is warm enough to be used for various domestic purposes, such as bathing and washing, while also posing a burn risk if the exposure is prolonged. In plumbing and health safety regulations, this temperature serves as a guideline to prevent scalding while providing comfort for users. While other temperatures may be encountered, particularly in specific applications or heating systems, 120 degrees Fahrenheit is recognized as the threshold for hot water across many standards and practices, including plumbing codes. Thus, it’s crucial for plumbers to understand this classification to ensure both safety and compliance in plumbing installation and maintenance.
