Heat Pump Water Heaters

The base case (pre-existing state) used to calculate energy-efficiency savings for new Heat Pump Water Heater (HPWH) is the average annual energy consumption of electric water heaters meeting the RTF’s current practice baseline. If a standard has been updated recently, BPA examines the potential prevalence of equipment not meeting the standard remaining in the marketplace.

Energy savings is calculated as the difference between the annual energy consumption of the base case and the energy efficient case, the HPWH. Additional factors include draw profiles (water consumption) and interaction with the home HVAC system.

Requirements and Specifications

These measures are available for new and existing single-family homes and manufactured homes. Savings for multifamily homes have yet to be demonstrated. In existing homes, the HPWH must replace an electric storage water heater on a one-to-one basis.
HPWHs must be;

(1) listed on BPA’s HPWH Qualified Products List and

(2) installed, according to manufacturer’s specifications. The installer must have received installation training from the manufacturer of the installed HPWH equipment, if available.(If a customer believes a product should be on the list, and it is not, it should use the COTR Request and Acknowledgment Procedure to request approval to use the product.)
