Ask This Old House Features Geothermal November 25 2019, 7 Comments
"Ask This Old House" featured a geothermal installation in its latest episode, "Switch, Affordable Geothermal | Ask TOH."
The segment focuses on a compact sonic drill rig, which can cut a 7-hour drilling process to about 30 minutes! The rig employs 10-foot casing lengths that can be used over again from job to job. The rig also retains the drilling fluids and recycles the water to prevent messy slurry escaping onto the lawn.
