The MSEC Geothermal Conductivity Test measures the amount of the on site 'ground source energy asset' available for use by a geothermal heat pump system. These tests are used for larger commercial applications, and is recommended to be conducted before any system design is attempted.

The 48 hour MSEC Geothermal Conductivity Test is run per (strict) G.R.T.I. specifications. Data from the test is downloaded to GRTI within 1 working day from completion of test, with full report delivered to client within two weeks of completion of test. (see report below)

A full test includes the following materials, drilling, and labor:

1. Utility marking by JULIE.

2. Bore up to 300 foot vertical bore with a diameter of up to 6 inches. Depths in excess of 300 feet are done on a per foot basis.

3. Install HDPE u-bend geothermal loop up to 610 feet at 1 inch in diameter.

4. Grout to 1.0 conductivity using a mix of one part Thermal Grout Lite with five parts Badger geothermal silica sand.

5. Allow installed loop to adjust back to pre-existing temperature by waiting seven days before the test begins. (Heat is created by the drilling process.)

6. Attach pump, heaters, and GRTI data logger to the loop to record the estimated average heat capacity (Btu/cubic ft degrees F), thermal conductivity (Btu/hr-ft-degrees F.), and estimated thermal diffusivity (square ft/day).

7. Run test uninterrupted for 48 hours.

8. Time to complete the analysis is approximately two weeks after the field test is complete.

9. MSEC supplies written report. Report Example.

Spoils from the drilling are left on site, but clean up of bags, pallets, and all other construction debris is included. The test loop can be incorporated for use into the loop field. Copy of drillers log provided.
