Yanmar's Variable Refrigerant Flow GHP systems provides powerful and efficient heating and cooling for all types of buildings. By using a very efficient natural gas engine to drive dual scroll compressors the VRF can reduce electricity usage by 90% compared to traditional heating and air systems, by using natural gas the Yanmar VRF can produce lower amounts of harmful chemicals such as 80% less NOx, 100% less SOx 

and 35% less CO2 then coal. The Yanmar VRF compared to other electric heating  and air systems can reduce utility cost by 30-70% depending on local utility cost.
