Solstice® HFO Refrigerants make decarbonising residential heating easier

Rapid heat pump deployment is an integral part of REPowerEU, the European Commission’s plan to ensure energy independence from Russia before 2030. It’s also instrumental for achieving the region’s 2050 net zero target.  Households across Europe account for 27% of final energy consumption while 79% of household energy is channelled into space and water heating.  Honeywell Solstice® HFO refrigerants provide compelling benefits across the residential value chain: forward-thinking heat pump manufacturers gain a low-cost opportunity to decarbonize home heating systems; homeowners can cost-effectively replace fossil fuel boilers with a source of clean heat; and installers get a solution that can be safely implemented and serviced.

Why choose Solstice® HFO Refrigerants for residential heating?
