Energy Savings tips for Water Heating


All of us use hot water on a daily basis from showers, to washing clothes, to dishwashers.  Our main focus is to have hot water and not particularly energy savings.  According to SRP, 12-20% of your annual energy usage goes towards producing hot water.  Changing our focus and habits with some simple low cost solutions can give us both hot water and result in savings. 

Here are some helpful hints to lower your bills in relation to water heating:


  • Upgrade your showerhead to a low-flow unit and save on gallons of water plus the energy used to heat the water.  A family of four can save up to 15,000 gallons of water per year.
  • Use low-flow aerators for faucets.  A family of four can save up to 8,000 gallons of water per year.  An aerator will use less water but flow stronger.
  • Repair any leaky faucets.  According to APS, one drip per second can waste 400 gallons of water a year. 
  • Set your thermostat to 120 degrees for normal use and lower when away from home for long periods of time.  You can save between 3 and 5 percent on energy cost for every 10 degrees you lower your set temperature.
  • Use your dishwasher efficiently by washing full loads.  If you wash your dishes by hand you may want to consider changing your habits and use an ENERGY STAR dishwasher.  According to ENERGY STAR, hand washing costs $431 more in energy and water than using an ENERGY STAR qualified dishwasher.  Here are the benefits:
    • Save money – up to $40 per year
    • Save time – 230 hours of personal time
    • Get better cleaning – dishwashers use 140 degree water for better cleaning
    • Save energy & water – save approximately 5,000 gallons of water per year
    • Save the environment – reduce air pollution and green house gases
  • Use your clothes washer efficiently by washing in cold water as much as possible.
