Choose an efficient water heater

Why? If you are in the market to replace your water heater, consider the energy efficiency of the system. The higher the energy factor (EF), the more efficient the water heater is. Water heaters typically have a 10-15 year life and today's ENERGY STAR® certified heat pump water heaters are much more efficient than conventional water heaters. Solar water heating systems are also great options to reduce your water heating costs.
If you are in the market to replace your water heater, consider the energy efficiency of the system. Demand (tankless) water heaters and solar water heating systems are also great options to reduce your water heating costs.

What to look for:

  • Efficiency ratings. These include the Uniform Energy Factor (UEF) and First Hour Rating (FHR). A higher UEF indicates a more efficient water heater. FHR is the amount of hot water a water heater can supply in an hour if it starts with a full tank of hot water. Visit the ENERGY STAR website for more detailed guidance.
  • The right size for your home. A water heater with a high FHR may use more energy, so be sure to balance your household's hot water needs with your energy budget. The U.S. Department of Energy offers a worksheet to help you find the right water heater size based on your water use habits.
  • A reputable contractor to install your system.
