What temperature kills bacteria in hot water tank?
According to the American Society of Sanitary Engineering, you should set your water heater between 135 and 140°F. At this temperature, you’ll kill any legionella present and stop any more from growing. This high temperature will also kill bacteria besides legionella that may be present.
What is too hot for water heater?
CDC recommends your water heater temperature set at 120 degrees Fahrenheit. OSHA has a different hot water temperature recommendation. OSHA recommends you keep your water heater at 140 degrees Fahrenheit so your risk of being exposed to microorganisms and Legionella is reduced.

An electric storage-tank-style water heater has two thermostats because it has two heating elements. The thermostats are designed so only one element is active at a time. The reason only one element is active at a time is because it allows for smaller wire sizes and lower amperage demand when in operation.
Does turning up water heater make hot water last longer?
When you raise the water heater temperature, the tempering valve will automatically reduce the volume of hot water in the mix to prevent scalding. Thus, the rate of consumption DOES depend on temperature. The lowered rate WILL make the hot water in the heater “last longer”.
