New Product Just Released... 1 1/4" Quadbone.....
For the commercial big guys going deep with there bores!!!!
Now that Double U-Bends are getting traction. We were appoached for a Double Ubend clip for 1 1/4" pipe. So, we built the tool. 600 ft bored holes are being drilled right now as I type this out. A school in Virginia is getting 26 - 600ft bores with 1 1/4" Double U-bends and our Quad Bones. Why not get the most from your bored hole as drilling is expensive. All the independant testing listed below will help this industry move forward.. Wheather you want fewer holes or just better heat transfer this simple idea does it. Please read more on the testing below....

Double U-Bends save 20%-40% on your geothermal bore fields..
Read Below !!!!!!!!!!!!
Home owners or business owners needing vertical geothermal bores!!
Demand double ubends with "Quad Bones"
Remember this is your building and you will live with it forever.
Either cut 1/3rd of the bore field or get a 1/3rd advantage from your
geothermal bore field..
It's your project.
Executive Summary From Oak Ridge Laboratory
To The Department of Energy United States
· Both the field tests and the computer simulations concurred that the double U-tube GHX requires 36% less borehole depth compared with a conventional single U-tube GHX while retaining same performance at given building load and ground condition [with a 1.85 Btu/(hr-ft-˚F) thermal conductivity]. Other new GHXs being tested also show the potential to reduce the required borehole depth, although the reductions are smaller (20-30%). A larger reduction in required borehole depth can be expected at locations where the ground has better thermal conductivity, as shown in Fig. E1

In-situ thermal response tests (TRT) have been carried out on six boreholes in Oklahoma City, Oklahoma at the Hope Crossing (Habitat for Humanity) site. The set of boreholes include coaxial and double U-tube heat exchangers, as well as conventional U-tube heat exchangers. This TRT study is a part of a larger project, where the boreholes are connected to ground source heat pumps to cool and heat homes. The TRT study is the first part of a larger project to evaluate the thermal performance of different types of ground heat exchangers. The TRT tests and subsequent data analyses provide estimates of the soil thermal conductivity and the borehole thermal resistance of each heat exchanger. Potentially the borehole depth and/or number of boreholes can be reduced for an installation if the borehole resistance is lowered. The double U-tube heat exchanger with enhanced grout has the lowest borehole resistance, followed by a single U-tube heat exchanger and a coaxial exchanger both with enhanced grout. The length of the double U-tube heat exchanger with enhanced grout could have a 20% to 40% length reduction compared to a conventional U-tube heat exchanger with bentonite grout. The amount of reduction is dependent on parameters for each installation such as soil thermal conductivity.
Geothermal Sure Clip LLC believe in getting the most heat transfer possible from your geothermal bored holes. You can pick from a "Dog Bone" that simply holds a single U-Bend apart in the bore and maximizes the heat transfer.. OR Go big with our "Quad Bones" for tradition HDPE for Double U-Bends for heat transfer not to be surpassed..
All of our geothermal spacer clips are designed with the idea that the clips should all stay in place and not be dislodged by the tremie pipe. Angled deflective ribbing creates a non-snagging condition so the tremie pipe or its connectors cannot cause the clips to be dislodged from the main geothermal pipes that the clips are attached to. So They Stay In Place !!!!!!
