Watch Your Water Heater Settings
If the temperature is set too high, you could be wasting energy
Some manufacturers set water heater thermostats at 140 degrees, but most households usually only require them to be set at 120 degrees. Consider lowering your water heater’s temperature to save energy and slow mineral buildup in the heater and pipes.
