Hot water is defined as water at what temperature or higher?

Hot water is typically defined as water that is at least 110° F or higher. This temperature is significant because it is considered warm enough for most household tasks without posing an undue risk of burns or scalding, especially for vulnerable individuals such as children or the elderly. In plumbing and various safety codes, temperatures below 110° F are often classified as warm, while temperatures above this mark transition to what is commonly referred to as "hot." This definition helps in setting standards for water heater thermostats and ensuring that the water delivered to taps is comfortable and safe for typical uses like bathing and cleaning. Understanding this threshold is fundamental for both plumbing systems and personal safety in residential settings.
