Ask This Old House Features Geothermal November 25 2019, 4 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.
View the 13-minute video on the ground source heat pump installation in Albany. The geothermal piece starts at 9:10.

Thank you for your interest, Robb.
Dandelion Energy, the GHP installer featured in this “Ask This Old House” episode, operates exclusively in New York State.
As far as I can tell, having received no response from the drill rig manufacturer, this Terra Sonic drill rig is proprietary to Dandelion and thus not available for purchase by any other company.

Is this available in Minnesota?

Thanks for your interest Chris.
We have contacted the drill rig manufacturer to see if there are other installers in New York that use a Terra Sonic drill rig.
Meanwhile, check our Members Map (Membership>Members Map) to find an installer in your area.
