Refrigerants for Residential Heat Pumps

Maximum Performance. Minimal Impact.

Heat pumps, powered by electricity from renewable sources, are a crucial technology for the decarbonization of home heating and cooling. Today’s heat pumps are several times more energy efficient than natural gas boilers, and demand for them is surging around the world. But careful refrigerant choice is essential to unlocking the full potential of heat pumps.

Opteon™ hydrofluoroolefin (HFO) refrigerants provide the best combination of safety, efficiency, and sustainability in residential heat pump applications. In fact, recent implementations showed up to 29% energy efficiency improvement and more than 40% higher capacity compared to alternative refrigerants, while insuring effective operation even at very low ambient temperatures. Opteon™ XL20 (R-454C) addresses the challenging requirements of residential building renovation, high temperature sanitary water production, and energy-efficient operation in cold climates and across the seasons.

Heat pump solutions for today and tomorrow

Recent improvements have enabled heat pumps to perform better in both warmer and colder climates, and as home heat pump design evolves to become more flexible and efficient, low global warming potential (GWP) Opteon™ refrigerants offer innovative solutions to move residential heating and cooling aways from yesterday’s fossil fuel-based systems and into a more sustainable future.

With their ASHRAE safety classification of A2L, Opteon™ products provide heat pump manufacturers with versatile and highly efficient replacements for legacy refrigerants like R-410A and R-22 while allowing simpler equipment design, installation, and maintenance compared to highly flammable alternatives like propane.

Opteon™ refrigerants for heat pumps include:
