At what temperature, in degrees Fahrenheit, is the maximum water temperature typically limited to by a water temperature limiting device?

The typical maximum water temperature limit set by a water temperature limiting device is generally 120° F. This temperature is specifically chosen to reduce the risk of scalding, particularly in residential applications where young children, the elderly, and individuals with sensitive skin may be present.

A water temperature above 120° F significantly increases the risk of burns and scalds. For instance, at 140° F, it only takes a few seconds of exposure for a serious burn to occur. Therefore, setting the limit at 120° F provides a safer experience while still allowing for effective sanitation and comfort during normal usage of hot water in household settings.

Other listed temperatures, while they may be safe in specific contexts, do not reflect the commonly accepted limit implemented to prevent burns.
