USA: The US Department of Energy (DOE) announced that four more manufacturers, Bosch, Daikin, Midea and Johnson Controls, have met the challenge of heat pumps for cold climates.

Launched in 2021, the U.S. Department of Energy’s Cold Climate Residential Heat Pump (CCHP) Technologies Project aims to accelerate the adoption of heat pump technologies by supporting innovation and manufacturing. It brings together public and private sector stakeholders to address technical challenges and market barriers to adoption.

Following the successful production of heat pump prototypes, Bosch, Daikin, Midea and Johnson Controls will join previously announced partners Lennox International, Carrier, Trane Technologies and Rheem in the next phase of the competition. This phase will involve installing and monitoring more than 23 prototypes in various cold climate locations throughout the United States and Canada over the next year.

DOE is now reaching out to nearly 30 states, utilities, and other partners that were part of the initial commitment to encourage CCHP adoption. The Department of Energy says it will continue to work with partners to develop programs, incentives, education and outreach campaigns that will help consumers better understand the benefits of these new developments.

The competition states that the prototypes provide 100% heating performance without the use of auxiliary heat and with significantly higher efficiency at 5°F (-15°C).
