Heat Pump Water Heater Rebate

Get a $500 rebate when you buy a qualified heat pump water heater!

A heat pump water heater is up to twice as efficient as a conventional electric water heater. Heat pump water heaters work like a refrigerator, but in reverse. While a refrigerator pushes heat from inside the unit out to the air around it, a heat pump water heater uses fans and an evaporator to pull warmth from the surrounding air and transfers it to water in the storage tank. Because it uses the warm ambient air temperature to do most of the work, it is a very efficient way to heat water. 

Considerations when determining if a heat pump water heater is right for you:

  • Identify whether a heat pump water heater is suitable for your home: Visit the Hot Water Solutions website for more information. This site was developed in partnership with Puget Sound utilities and the Northwest Energy Efficiency Alliance (NEEA), as a resource to customers.
  • Your new heat pump water heater would be located in a space with about 1,000 cubic feet.
  • For the most efficient operation, the air temperature where the water heater is installed should average 40 degrees F or above.
  • Because the heat pump exhausts cool air in the area where it is located, the water heater should be installed in a location that would isolate cool air, or be ducted to the outside.
  • The mechanical components of a heat pump water heater generate noise – similar to a dishwasher (around 45 decibels). Consider the noise factor in making your purchase decision and placement.
  • Overall, the ideal location for a heat pump water heater is in a garage or unheated/unfinished basement.


  • The heat pump water heater must be:
    • Installed in PUD service territory.
    • Replacing an existing electric hot water tank.
    • A qualified model (see related information section).
  • Installer (either contractor or homeowner) must receive manufacturer training prior to installation.
    • Some manufacturers offer installation videos. 
    • Check out the Do-It-Yourself installation tips for more information prior to installation.
