What is the minimum required temperature for stored hot water to avoid bacteria growth?

To prevent the growth of harmful bacteria such as Legionella, which can thrive in warm water, it is crucial to maintain a minimum storage temperature for hot water. A temperature of 60°C (140°F) is generally accepted as the minimum requirement for storing hot water. At this temperature, the bacteria's ability to reproduce is significantly inhibited, thus reducing the risk of waterborne illnesses.

Holding water at this temperature not only helps to ensure safety but also supports effective sanitation practices in plumbing systems. Industry standards typically emphasize that any stored hot water must be hot enough to prevent bacterial growth, and 60°C meets that criterion effectively. This temperature allows systems to function properly while safeguarding public health.
