LG Therma V Heat Pump - 9.0kWHigh performing unit R32 refrigerant has a low Global Warming Potential (GWP) of 675, and has been shown to have a remarkably reduced environmental impact compared to other refrigerants such as R410A. Its high efficiency is proven as just a smaller amount of R32 is required (15% less gas charge compared to R410a) with better heating performance at lower ambient temperatures whilst using less refrigerant per kilowatt of capacity delivered.
