As policymakers, builders, utilities, and end users seek to reduce the greenhouse gas impact of our homes, it is critical to address the low installed efficiency of traditional equipment serving what is often the most significant load, space heating and domestic hot water. New Thermally-driven Heat Pumps (THPs) have been developed as a packaged solution to provide both space heating and domestic hot water, achieving an equivalent of 140% AFUE in both lab and field environments and represent a new product category for residential space heat, being built by multiple manufacturers. This session will provide an overview of the technology, and share energy performance, operating cost, CO2e emissions basis and comfort results from multiple lab and field demonstrations, including sharing the perspective of installing contractors.
