Loop Installation

Napier's Plumbing & HVAC will design and install a geothermal loop system for your residential or commercial job. There are four types of geothermal loops.

Closed loop
systems circulate a water-based solution through a “loop” of small diameter, underground pipes. Closed loop systems can be installed horizontally, vertically, or in a pond. Open Loop systems utilize an existing water well. Regardless of whether the system is open or closed, heat is transferred to or from the home to provide year-round comfort no matter what the outdoor temperature is.

The three types of closed loops are:

Horizontal Loop

Horizontal loops are often considered when adequate land surface is available. Pipes are placed in trenches, in lengths that range from 100 to 400 feet. Click on loop diagram to see it enlarged.

Vertical Loop

Vertical loops are the ideal choice when available land surface is limited. Drilling equipment is used to bore small-diameter holes from 75 to 300 feet deep. Click on loop diagram to see it enlarged.

Pond Loop

Pond (lake) loops
are very economical to install when a body of water is available, because excavation costs are virtually eliminated. Coils of pipe are simply placed on the bottom of the pond or lake. Click on loop diagram to see it enlarged.

The fourth type of loop is an Open Loop.

Open loop systems utilize ground water as a direct energy source. In ideal conditions, an open loop application can be the most economical type of geothermal system. Click on loop diagram to see it enlarged.
