Job Details & Photos

Thank you for your interest in the geothermal work we do. We hope the following pictures will answer some questions you may have about the loop installation process. Each geothermal application is designed to be equally efficient.

Vertical / Drilling
Vertical bore holes provide the least disruptive form of geothermal loop installation. Because of the compact size of our rig, an average residential loop can be installed in a 10' x 20' utility free space. A hole approximately 150ft. deep is required for each ton of heating capacity. Holes are placed 10ft. apart.
Horizontal / Trenching
Approximately 140ft. of trench is required for each ton of heating capacity for a horizontal geothermal system. A 36" wide, 60" deep trench is excavated and 600ft. of 3/4" PE pipe is laid in the bottom in an extended slinky design.

Pond Loop
Water temperatures at the bottom of a pond maintain relatively constant temperatures providing an alternative geothermal loop application. Minimum pond requirements are 3/4 acre in size with an average depth of 8 ft. Pond loops are made up of specially designed 300' coils of 3/4" PE pipe. Each coil allows for about 1 ton of heating/cooling capacity.
Hook-Up
An underground manifold of 3/4" PE pipe is created to connect piping from each hole/trench. The manifold is then attached to a 1 1/4" PE pipe that goes through the house wall. The interior plumbing is installed and the loop is connected to the flow center and furnace. The system is then flushed and filled with a 20% methanol solution.
