Electric Heat Pump Water Heater Program

Electric Heat Pump Water Heater Program

Electric Heat Pump Water Heater Program


To move toward California’s Zero Net Energy Strategic plan, more electrical end uses in homes need to be adopted.

Water heating is one area where an electric end use can replace natural gas.  Electric Heat Pump Water Heaters are becoming more and more efficient and can make a real difference in terms of Green House Gas emissions compared to conventional natural gas storage water heaters.

This Program will replace your existing gas water heater with an ENERGY STAR® heat pump water heater with a 50 gallon minimum with an Universal Energy Factor (UEF) of 3.17 or greater

To encourage the adoption of this new technology, this Program will provide technical assistance and incentives to cover 50 to 100 % of installation costs depending on income levels for a select number of systems in 2018.


  • Own a single family home in Alameda or Contra Costa Counties
  • Fill out a pre- and post installation survey

How it Works


It’s generally easier to move something than to make something. Putting that principle to use, HPWHs use electricity to move heat from one place to another instead of generating heat directly.

To understand the concept of heat pumps, imagine a refrigerator working in reverse. While a refrigerator removes heat from an enclosed box and expels that heat to the surrounding air, a HPWH takes the heat from surrounding air and transfers it to water in an enclosed tank.

During periods of high hot water demand, HPWHs switch to standard electric resistance heat (hence they are often referred to as “hybrid” hot water heaters) automatically.  HPWH come with control panels that you to select from different operating modes, which include:

  • Efficiency/Economy – Maximizes energy efficiency and savings by only using the heat pump to heat water
  • Auto/Hybrid – The default setting is ideal for daily use, providing energy-efficient water heating with sustained heat
  • Electric/Heater – This high-demand setting is the least energy-efficient, using only the electric element to heat water
  • Vacation & Timer (not available on all models) – Save on your energy when away from home by placing the unit in “sleep” mode until you return

This project is funded through the East Bay Energy Watch (EBEW), a local government partnership between Pacific Gas and Electric Company (PG&E),  StopWaste, Alameda and Contra Costa Counties.
