In this Better Buildings Residential Network peer exchange call, hear about a study of grid-connected heat pump water heaters in 24 low-income households in the Southeast U.S. that enabled dispatchable energy storage and shifted electricity use to cheaper, off-peak periods. Also, hear results from a study that examined combined water heating and space conditioning performance of a residential cold climate heat pump capable of heat recovery that compared the performance to an identical home with a standard ducted split heat pump and unitary heat pump water heater.
