Heat Pump Water Heater Instant Reward

The PUD has partnered with Heat Pump Water Heater (HPWH) manufacturers and local retailers to offer reduced pricing on HPWHs. So when you purchase an eligible HPWH from a participating retailer or local contractor, the price you pay includes a $500 PUD Instant Reward!

HPWHs work like a refrigerator, but in reverse. While a refrigerator pushes heat from inside the unit out to the air around it, a HPWH 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 HPWH is right for you:

  • To identify whether a HPWH is suitable for your home, visit the Hot Water Solutions website.
  • For the most efficient operation, the air temperature where the HPWH is installed should average 40 degrees F or above.
  • Because the heat pump exhausts cool air in the area where it is located, the HPWH should be installed in a location that would isolate cool air, or be ducted to the outside.
  • The mechanical components of a HPWH 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 HPWH is in a garage or unheated/unfinished basement.
