Water Heater

  • Set the temperature to 120 degrees.
  • Insulate with an inexpensive water heater blanket. (Electric-only homes.) 
  • Insulate hot water piping where possible.
  • Use less hot water.
    • Take short showers instead of baths.
    • Install low-flow showerheads and faucets.
    • Shut the water off when you’re not using it.
  • Buy a more efficient unit. Look for the ENERGY STAR seal.
