This January 2019 report by the Regulatory Assistance Project (RAP) examines electric heater heating opportunities available today and in the near future. It explores technology options for electrification of water heating such as electric resistance (ER) water heaters and air source heat pump (HP) water heaters. Each option is assessed against certain predefined criteria (e.g., saving consumers money, making the grid more flexible and emissions reductions).
