Easy Ways to Reduce Hot Water Consumption

If your water heater is in good condition but undersized for your household, reducing your hot water usage is the easiest and cheapest solution.

  • Install low-flow showerheads. All new showerheads provide a maximum of 2.5 gallons per minute (gpm), compared with up to 5 or more gpm of many older heads. Some new heads are as low as 1 gpm.
  • Install low-flow aerators on bathroom faucets, especially if you have kids who tend to leave the water running.
  • Use a cold-water rinse for all laundry loads. Warm water rinses no better than cold, so there's no reason to use it.
  • Run only full loads in the dishwasher and clothes washer.
  • Let the dishwasher do the work. Don't waste a lot of hot water pre-rinsing dishes in the sink; just scrape off the food (or soak dried-on food) with a little rinse water.
