Setting your water heater to 130°F (54°C) is slightly above the standard recommended residential temperature of 120°F (49°C). While 130°F provides extra thermal capacity and helps inhibit the growth of harmful Legionella bacteria inside the tank, it also increases energy consumption and significantly raises the risk of accidental scalding, particularly for young children and elderly occupants. Verification: Measure hot water temperature at a nearby tap using a digital thermometer to confirm exact output levels.
