Opening up Geothermal Vertical Loop Market

In the geothermal energy business for more than 45 years, Buchanan and Hall built a strong reputation installing excavated and horizontal drilled geo-loops across Ontario. But when customers began requesting geothermal vertical loop systems, the company needed outside help.

“We worked with other companies when we needed vertical loops. We thought it would be nice to start installing vertical loops for residential and small commercial projects where vertical is the best option,” Al Hopper, drilling manager, said. “I have a background in drilling water wells for more than 30 years, so I have always been interested in what different machines were on the market.”

After researching options — reviewing trade magazine ads, studying websites, and watching videos to see how different features work — Hopper found the Geoprobe^® DM250 to be the ideal fit.

"I like the quality of the manufacturing and the simple design for operating," Hopper said. "It makes training new drillers easier."

Dependable Support, Right Here in North America

The deciding factor: reliable Geoprobe^® support network and customer portal.

“With the service centers and Centerpoint Connected, it has simplified any minor things we had to diagnose,” Hopper said. “The DM250 opens up more options we can offer our customers depending on drilling conditions and space required to go with geothermal.”

Proven in the Field

One of Buchanan and Hall’s first DM250 jobs was a light commercial geothermal vertical loop project requiring 30 boreholes on a 20-foot grid spacing.

“The machine was easy to move to each spot using the 4-wheel-drive. We only had to use mats on one site,” Hopper said. “It was less work than moving a larger drill to each hole.”

Features That Make a Difference

Hopper highlighted several DM250 features that simplify geothermal vertical loop installations:

• Size-to-Power Ratio: “It has a big rig feel in a lighter package while still running 20-foot drill rods.”
• Compact Footprint: “We had one residential site with many sprinkler heads to avoid. The machine was easy to drive in and not damage existing landscaping.”
• Rod Carousel: “It saves a lot of looking up and holds 160 feet of drill rod in the carousel.”
• Quality Manufacturing: “The fit and finish of the machine is high quality. The deck panels are aluminum with a textured no-slip finish, which are easy to remove to get access and will stay looking great for years.”
• Array of Options: “The variable speed 4X3X13 mud pump is lightweight and has good flow for any conditions. The onboard compressor is also a handy option.”

The Perfect Fit

From maneuverability to operator comfort and North American support, the DM250 has proven to be exactly what Buchanan and Hall needed to expand their geothermal capabilities efficiently and confidently.
