Great instructional video that touches on the concept behind geothermal and the benefits for homeowners. FYI the Earth's temperature in Calgary is a little cooler...around 47F (as opposed to the 55F in the video).Video courtesy of geothermalgenius.org
Thermal Creek has successfully installed Costa Rica's first geothermal borehole and performed a thermal conductivity test of the soil. The test was performed for the Vista Bahia project in the Dominical region. Vista Bahia is a multi-storey luxury condominium community that will strive to live in harmony with the land’s natural beauty.
