What is the maximum water temperature that should be maintained in a hot water cylinder to prevent scalding?

Maintaining water temperature at 60 degrees Celsius in a hot water cylinder is important for preventing scalding while also ensuring that the water is hot enough to minimize the growth of harmful bacteria, such as Legionella. Temperatures above this level increase the risk of burns upon contact with skin, especially for vulnerable populations such as children and the elderly, who may have a lower tolerance to heat.

At 60 degrees Celsius, the water is hot enough to be effective for cleaning and sanitation purposes, but it strikes a balance where the risk of scalding is significantly reduced, as it generally takes longer for water at this temperature to cause severe burns compared to higher temperatures. By adhering to this guideline, plumbers can help ensure safety in residential and commercial installations, making it a widely accepted standard in plumbing practices.
