GE’s hybrid water heater consumes up to 62 percent less energy than a standard electric water heater. A compressor and evaporator are integrated into the top of the unit and draw ambient heat from surrounding areas using variable speed fans. Coils wrap the internal tank to secure it to the bottom and transfer the heat to the water. It features four operating modes: E-heat, Hybrid, High Demand, and Standard.; 800.626.2005.
