Solstice® 454C, a forward-looking solution for heat pumps (R-454C)

With the entry into force of F-Gas III on 11 March 2024 in the EU, Solstice® 454C refrigerant is a sustainable solution for reducing the environmental impact of heating systems.

Replacing gas-fired boilers with cheaper, safer and more energy-efficient heat pumps is a major area of development for reducing the use of fossil fuels and thus decarbonising residential heating.

R-454C is fully in line with this approach, thanks to its very low GWP of 146. It is an ideal long-term solution for aerothermal and geothermal heat pumps and thermodynamic storage tanks, replacing R-410A and R-32 refrigerants.

Air-source heat pumps using Solstice® 454C are less expensive to design, whether in split or monobloc configurations, depending on the end customer’s preference. Rated A2L (low flammability), R-454C also makes it possible to produce heat pumps that are safer to install and maintain than heat pumps running on propane (rated A3, highly flammable).

Solstice® 454C heat pumps reduce end-customer life-cycle costs thanks to a unique innovation, using components optimised to improve energy efficiency by up to 11%.
