Solstice® Refrigerant Helps Decarbonise London Homes

As part of its ambition to become carbon neutral by 2030, Southwark Council in south east London developed a plan to decarbonise the gas-powered heat networks used by thousands of council homes across the borough.

Over 2,000 homes were decarbonised.

Southwark Council brought in renewable energy provider Vital Energi (with its partners ICAX and J&E Hall) to replace legacy gas boilers with modern heat pumps powered by low global warming potential (GWP) Solstice® N15 (R-515B) refrigerant – a 91% blend and sister product of Solstice® ze (R-1234ze) from Honeywell.

Choose the right refrigerant for your heat network.

Solstice refrigerant met Vital Energi and the council’s requirements for safety, efficiency and cost. Both Solstice N15 and Solstice ze support temperatures up to 100°C (the council’s heat network typically operates between 75-80°); offer low complexity, which helps to reduce capital costs; and deliver high efficiency, which helps to decrease both the financial cost and CO2 emissions related to power consumption.
