Heat pump prototypes withstand subfreezing weather

The US Department of Energy (DOE) has announced that four additional heat pump manufacturers successfully produced heat pump prototypes as part of the Residential Cold Climate Heat Pump (CCHP) Technology Challenge, a DOE initiative to accelerate the deployment of heat pump technologies by supporting innovation and manufacturing.

The Challenge specifies that prototypes deliver 100% heating capacity without the use of auxiliary heat and with significantly higher efficiencies at 5 degrees Fahrenheit. Through the Challenge, DOE is working together with industry to accelerate widespread commercialisation of efficient cold-climate electric heat pumps, which can provide clean heating and cooling for millions of American families and help meet President Biden’s goal of 100% carbon pollution-free electricity by 2035 and a net-zero carbon economy by 2050.

“Deploying next-generation technologies like heat pumps is critical to the Biden-Harris Administration’s efforts to ensure that Americans have access to more affordable clean heating and cooling options—no matter where they live,” said US Secretary of Energy Jennifer M. Granholm. “By supporting industry advancements, DOE’s Cold-Climate Heat Pump Challenge is helping get cost-effective clean energy technology into homes across America—keeping families warm during the coldest months and saving them money.”
