Purchase Our Closed Earth Loop Design Service


Proper closed earth loop design is necessary for optimum performance of your geothermal heat pump system.

We have years of experience designing earth loops for people all over the United States. In addition, we have observed what works and what does not work when it comes to effective design. We know that corners cannot be cut when it comes to how much pipe is needed. We have seen a lot of over-sizing of geothermal heat pumps and under-sizing of earth loops, which makes for an inefficient system that has a short lifespan, or one that won't work at all when outside temperatures are colder.

We can correctly design any kind of an earth loop: horizontal single-pipe trench loop, horizontal slinky, pond, or lake loops. We can give you all the design information for vertical bore loops so you can have the bores drilled by a local well or geothermal drilling company. Save yourself the worry and let us design your geothermal closed earth loop.

Trenches for a closed earth loop

Closed Earth Loop Design includes the following:
  • Earth loop field layout drawings showing your pipe size, lengths, spacing, and depths for best efficiency and system payback

  • Manifold drawings that show how to build what you need for correct flow and easy flushing

  • Pump sizing and selection, with wiring schematics

  • Interior piping drawings showing how to connect your geothermal heat pump, pumps, and manifolds

  • Links to online or local sellers for all specialty earth loop parts

  • Installation and flushing instructions for your earth loop, including email and phone support (10-6 M-F, Noon-5 Sat Eastern, exc. Fed holidays)

By purchasing our Closed Earth Loop Design Service you agree that you are providing (via e-mail and/or phone) us with the information to design your geothermal loop, and that any results provided to you are based on the information you gave us.

We will need soil sample information for a horizontal loop design, and a site map showing any utilities, easements, or structures that might block excavation in the loop field area.


The cost for designing your closed loop is based on the size of your geothermal heat pump.
