Using the water heater accounts for about 11 percents of the average Minnesotan's carbon dioxide emissions. Here are a few simple steps you can take to reduce energy use of your water heater.

  • Turn your water heater's thermostat
    • Turn down your water heater's thermostat to the lowest setting that is comfortable for you and your family. For most people, 120 degrees Fahrenheit is sufficient and safe.
  • Switch to a low-flow shower head
    • Low-flow shower heads use about six gallons less water per minute compared to conventional shower heads, which dramatically reduces the amount of water and heat used when showering. 
    • Take shorter showers to save even more energy.
  • Wash clothes in cold water
    • Not only will you save energy, your clothes will last longer and the colors will stay brighter. 
    • Line-dry clothes to save even more energy.
  • Insulate your water heater tank
    • Adding insulation can reduce the heat lost while your water heater is in standby mode by 25 - 45 percent.
