This product extract the heat source from the tempered ground water or ground,and then transfer heat to hot water using side.Very good performance at very cold temperature.
1.Work efficiently at extreme cold winter, because ground water/ground is of nigher temperature than air in winter
2.Quiet running
3.Reliable &long lasting
4.Compact simplied design
5.Environmental friendly gas R407c
6.Automatic intelligent control system
