Geothermal heating/cooling system are growing in popularity because it is a green energy which provides better energy efficiency compared to conventional systems. Nothnagle Drilling, Inc. has properly installed numerous geothermal well fields from large commercial projects to single-family residential housing projects. Our services included:
  • Drilling the wells
  • Inserting the HDPE vertical loops or U-bends 
  • Grouting the annuls space between the pipe and hole wall using proper techniques
  • Trenching and fusing the horizontal headers into the building
  • Geothermal Test Wells and Thermal Conductivity Reports

How Geothermal Works

Fundamentally, geothermal systems work differently than ordinary heating and cooling systems. Conventional systems have to produce heat by burning some type of fuel, typically propane, natural gas or fuel oil. Geothermal systems don’t create heat; instead they collect and distribute it from the earth.

First, you should realize that the earth absorbs and stores nearly half of the sun’s solar energy. As a result, at a depth of six feet it maintains a fairly constant temperature of 45 to 70 degrees F. The geothermal system taps into that free, renewable energy and puts it to work.

The earth’s natural heat is collected in the winter by a series of pipes called a loop system. Fluid circulating in the loop system carries this heat to the heat pump where it is compressed and released as warm air or water to raise the inside temperature of the building.

In the summer, this process is reversed in order to cool the home. Heat is drawn from the home, rejected to the loop and absorbed by the earth. The result is a comfortable home all year round.

Since most of the energy used for heating and cooling is from the earth, geothermal systems are the most efficient and environmentally friendly systems on the market today. Below are the different options in which you can utilize this technology.

Economics of Geothermal

A geothermal system allows you to provide your family with a complete answer to your entire home’s heating and cooling needs. Geothermal technology allows the system to outperform any conventional system available today.

Comfort is only half of the benefits that a geothermal system offers.  The return on investment is 5-10 years on a geothermal system with up to a 80% reduction in your heating, cooling, and hot water bills.

There’s never been a better time to install a geothermal system. Recent legislation has created new incentives for qualified geothermal systems. The recent American Recovery and Reinvestment Act of 2009 in the U.S. offers a 30% tax credit for the installation cost of the geothermal system.
