What is the maximum temperature to which hot water should be regulated?

The regulation of hot water temperature is typically guided by safety and health standards to prevent scalding and ensure user comfort. The maximum temperature to which hot water should be regulated is commonly set at 120 degrees Fahrenheit. This temperature is considered a safe limit for residential hot water systems. Above this threshold, the risk of serious burns increases significantly, especially for vulnerable populations like children and the elderly, who may not react quickly enough to avoid scalding.

Setting the water temperature at 120 degrees strikes a balance between ensuring water is sufficiently hot for tasks such as dishwashing and bathing, while minimizing the risk of burns. Many building codes and health organizations advocate for this limit, aligning with recommendations for safe hot water usage. Therefore, regulating hot water at or below 120 degrees Fahrenheit is the best practice for promoting safety while still meeting the needs of the household.
