Heat Pump Water Heater Program Information


How Heat Pump Water Heaters Work

Heat Pump Water Heaters (HPWHs) use electricity to move heat from one place to another instead of generating heat directly, like a refrigerator running in reverse.  While a refrigerator pulls heat from its interior and exhausts that heat into the surrounding room, a heat pump water heater pulls heat from the surrounding air and transfers it into the tank to heat the water.

  • Quick Facts:
    Hot water accounts for 15 – 20% of electric energy use.
  • Heat Pump Hot Water Heaters reduce water heating costs by up to 50%.
  • New or existing construction qualify for rebates.
  • Easily replaces existing tanks in most cases.
  • Can be homeowner installed with manufacturer training (see below.)
  • Best location is in unheated spaces such as garages or basements.
  • Rebates range from $300.00 for Tier 1 HPWHs and $500 for Tiers 2 and 3.

In order to qualify for the PUD’s program the heat pump water heater must:

  • Replace an electric resistance water heater when installed in existing homes.
  • Be installed with proper clearances from the manufacturer’s specifications.
