Legionella is a type of bacteria that can be found naturally in water sources such as lakes and rivers However, it can become dangerous when it grows and multiplies in man-made water systems, such as hot water tanks and pipes Legionella bacteria can cause a type of pneumonia known as Legionnaires’ disease, which can be fatal if not treated promptly In order to prevent the growth of legionella in your hot water system, it is crucial to maintain the right hot water temperature.
The optimal temperature range for preventing the growth of legionella bacteria in hot water systems is between 120°F and 140°F (49°C and 60°C) At temperatures below 120°F (49°C), legionella bacteria can survive and multiply, while temperatures above 140°F (60°C) can scald individuals and may not be practical for daily use Therefore, it is important to keep the hot water temperature within this optimal range to ensure the safety of your water supply.
Hot water tanks and pipes provide the ideal environment for legionella bacteria to grow and multiply The warm, stagnant water in these systems can become a breeding ground for bacteria if not properly maintained Legionella bacteria thrive in temperatures between 77°F and 108°F (25°C and 42°C), making hot water systems an ideal habitat for their growth Regularly flushing out your hot water system can help prevent the buildup of bacteria and maintain the water temperature within the recommended range.
