The KELIX® GHE transfers heat more efficiently
than traditional geothermal systems
The KELIX® GHE’s helical fins create turbulence in the liquid flow
With turbulent flow using the KELIX® GHE, more of the fluid contacts the Earth – which allows more heat to transfer
VS
With laminar flow using U-tubes, a boundary layer is created and less fluid contacts the Earth – hampering heat transfer
The KELIX® GHE’s outer pipe is made of a fiberglass material with heat-conducting additives
The KELIX® GHE outer pipe has xxxxxx added, which improves its ability to transfer heat to/from the fluid
VS
The HDPE used in traditional U-tube systems is an insulator, which traps heat in the fluid
The KELIX® GHE’s inner pipe is smooth, and made of an insulating material
By maintaining laminar flow in the KELIX® GHE inner pipe and using a special PVC, little cross-flow heat is exchanged
VS
In a traditional U-tube design, the out- and return-flows exchange heat with each other, reducing efficiency
The KELIX® GHE’s outer pipe provides a large surface area for heat transfer
The KELIX® GHE outer pipe is 3.55” in diameter, which provides over 11” of surface contact along the length of the tube
VS
Most U-tube systems have two 1” diameter tubes, which only provides 6.3” of surface contact along the ground heat exchanger
