Description
The main objective was to shift the energy use profile of water heaters on a daily basis from the 4 to 9 pm peak period to lower-cost hours thus, avoiding congestion on the grid and aligning with time of use (TOU) rates. The study assessed two different water heater technologies: smart control devices and smart hybrid heat pump water heaters.
