Legionella is a type of bacteria that can be found in natural water sources such as rivers and lakes When Legionella bacteria enters man-made water systems, such as water heaters, it can multiply and cause serious health risks Legionella bacteria thrive in warm water temperatures between 77°F and 108°F, making water heaters the perfect breeding ground Controlling the temperature of your water heater is crucial in preventing Legionella growth and ensuring the safety of your household.
The Occupational Safety and Health Administration (OSHA) has set guidelines for water heater temperatures to prevent the growth of Legionella bacteria According to OSHA, water heaters should be set to a minimum of 140°F to kill off any Legionella bacteria present in the water system Water heaters should also be set at a maximum temperature of 120°F to prevent scalding burns Maintaining the water temperature within this range is important to ensure the safety and health of your household.
