ENERGY STAR heat pump water heaters are slated to reach the market later in 2009. If you want to be the first on your block with this new technology, start planning your purchase today:

  1. Plan ahead for more control. By waiting until your current water heater fails, you will leave little time to research and select a qualified heat pump model. Your installer may need time to order the proper model, and it can take longer to install than a standard electric water heater. To make your life easier, plan ahead and have one installed before it's an emergency.

  2. Check product availability. Find out what qualified models are available on the market by viewing the ENERGY STAR Product List. You may then need to visit manufacturer Web sites or call local installers to determine who carries these units in your area.

  3. Consider your specific situation.

    • What size do I need? Water heater capacity or volume is measured in gallons. You can determine the size of your existing model by looking at the nameplate or the yellow Energy Guide sticker. If your current water heater meets your needs most of the time, you can probably replace it with one the same size. However, you may want to purchase a larger unit if you have added or are planning to add more occupants to your household or a new shower, faucet, dishwasher or washer that will be in frequent use. A contractor or retail salesperson can help you decide if a larger model is necessary.
    • Where will it be installed? Heat pump water heaters should be installed in interior spaces that remain between 40°–90° F year-round, and provide 1,000 cubic feet of air space around the water heater. They generally don't operate as efficiently in colder spaces, and can cool the spaces they are in. If possible, consider installing in a space with excess heat, such as a furnace room.
  4. Get a quote from a contractor or retailer. You may want to check a manufacturer or retailer's Web site to get a general idea of cost, but you will eventually need an installer to come to your home and give you a customized price. The installer should confirm the optimal size for you home and address all installation needs, such as proper placement, electrical service and condensate drainage or collection. When requesting a quote, remember to:

    • Request cost estimates in writing.
    • Ask for references.
    • Check the company with your local Better Business Bureau.
    • See if the company will obtain a local permit if necessary and understands local residential building codes.
  5. Search for rebates and utilize tax credits. You may be able to reduce your costs by taking advantage of rebates or tax credits. Be sure to review the eligibility rules before you make your purchase.

    • Use the Special Deals Finder
      Determine whether there are rebates available for ENERGY STAR qualified water heaters in your zip code.
    • Utilize the Federal Tax Credits
      Every ENERGY STAR qualified heat pump water heater model will qualify for a $300 Federal tax credit in 2009.
