Have you ever wondered why the temperature setting on your water heater is important? It’s not just about comfort; the temperature is also about safety. The plumbers at Mister Water Heater are often asked by our Indianapolis area water heater customers why their water needs to be at a particular temperature. The answer ties back to a bacterium called legionella. It’s a common inhabitant of our water system that poses serious health risks when not properly managed.
Legionella are bacteria found naturally in freshwater environments like lakes and streams. However, they become a health concern when they grow and spread in human-made water systems, including hot tubs, cooling towers, and water heaters.
If inhaled in aerosol form, such as through steam or mist from a contaminated water source, legionella can cause Legionnaires' disease, a severe form of pneumonia. It can also lead to Pontiac fever, a less severe respiratory disease.
Water heaters can become breeding grounds for legionella if not maintained at the right temperatures. The U.S. Centers for Disease Control and Prevention (CDC) suggests keeping water heaters set at a minimum of 120°F to prevent legionella growth. However, it is crucial to balance this with the risk of scalding, especially in homes with vulnerable individuals.
Ensuring your water heater is correctly installed and regularly maintained can significantly reduce the risk of legionella growth. This includes routine inspections for any sediments or malfunctions and ensuring the temperature is correctly set according to safety guidelines.
