Project Launch: 05/01/2022

Partner: Slipstream

The project team will conduct market research to investigate the technical potential and adoption considerations for 120V heat pump water heaters in ComEd territory.


While standard 240-volt heat pump water heaters potentially require costly panel or electric service upgrades for installation, 120-volt heat pump water heaters can plug into a standard wall outlet, lowering customer barriers for adoption. The project team will research the market readiness of 120V heat pump water heaters in ComEd territory and their applicability for residential customers; model the impact of usage profiles, draw patterns and cold climate conditions on 120V heat pump water heater efficiency and cost impacts; and determine the scale of the market opportunity for this technology, including best use cases.
