CHARLOTTE, N.C. — Bosch’s newest line of heat pumps will incorporate Honeywell’s Solstice low-GWP refrigerant.

As part of this collaboration, Bosch technicians will be trained in the safe maintenance and installation of these next-generation low-GWP solutions. The collaboration with Bosch also supports Honeywell’s recently announced plans to align its portfolio around three compelling megatrends, including the energy transition, a press release from Honeywell said.

Bosch’s Florida Heat Pump series will use Honeywell Solstice R-454B refrigerant, designed to reduce greenhouse gas emissions in residential and light commercial heating and air conditioning by 78% compared to traditional refrigerants. With the integration of Honeywell Solstice, Bosch’s heat pumps will be able to use a combination of electricity and refrigerants to move heat, providing an energy-efficient alternative to heating and cooling via traditional furnaces and air conditioners, the press release said.

“Honeywell continues to pioneer next-generation refrigerants for the industry that enable our global partners to meet their carbon footprint targets,” said Jeff Dormo, president of Honeywell Advanced Materials. “Bosch's selection of Honeywell's low-GWP refrigerant reflects our joint commitment to environmental responsibility and underscores our strategic alignment in assisting companies with their energy transition, mitigating the environmental impact of heating and cooling systems.”

The heating and cooling industry is undergoing a significant change in refrigerants, driven primarily by regulations under the American Innovation and Manufacturing (AIM) Act. To help installers prepare for the transition, Honeywell and Bosch are also partnering to share technical information on the refrigerant change, and to ensure that technicians know the best practices for the safe handling, maintenance, and installation of the new refrigerants.

“Bosch Home Comfort deeply values professional training on both the technology and best practices for safely installing the equipment as designed,” said Alexander Wuthnow, president and CEO of Bosch Home Comfort North America. “As the industry pivots to lower-global warming potential refrigerants, contractor education will become even more critical in 2024 and beyond. We are proud to partner with Honeywell to make critical resources easily accessible to installers and to further drive excellence and innovation in the industry.”
