    120°F is too low for a water heater. 135°F is the minimum necessary to prevent bacteria growth inside the tank. And like the other person said, your hot water will last a lot longer with a higher temperature. Just don’t crank it too far beyond 140° so you don’t accidentally burn yourself.

      120 is the lower limit for killing stuff off. Not much will live or grow at a sustained 120.

      I leave mine at 120 and every Sunday it kicks up to 135 for an hour for peace of mind.
