The US Department of Energy announced that American heat pump manufacturer Lennox International became the first partner in the US Department of Energy’s Residential Cold Climate Heat Pump Technology Challenge to develop a next-generation electric heat pump that can more effectively heat homes in northern climates relative to today’s models. Cold climate heat pumps (can provide high-efficiency heating in freezing temperatures without producing greenhouse gas emissions and can save families as much as USD 500 a year on their utility bills. This achievement is a massive step toward providing reliable clean heating and cooling for millions of American families through domestically produced CCHPS, which is crucial to reducing energy costs and achieving President Biden’s goal of a net-zero carbon economy by 2050. Space conditioning and water heating account for 46% of building emissions and over 40% of primary energy used in American residential and commercial. They also account for 42% of all building energy bills and 56% of household energy bills each year. DOE launched the CCHP Technology Challenge in 2021to accelerate development and commercialization of next-generation heat pumps by supporting American innovation and manufacturing. Lennox International, headquartered in Richardson in Texas developed the first prototype that achieved the Technology Challenge’s standards about a year ahead of schedule. The prototype delivers 100% heating at 5 degree Farenhite at double the efficiency, and 70% to 80% heating at minus 5 degree Farenhite and minus 10 degree Farenhite. DOE’s Oak Ridge National Laboratory validated the performance and efficiency of Lennox’s prototype.
