Geothermal Savings

One of the most appealing parts of geothermal heating and cooling to the normal homeowner is the savings they can expect to get. Depending on your current system, geothermal systems can save you around 30% and 60% on your operating expenditures.

How it Works

Geothermal heating and cooling systems are complex systems when you consider that they are converting electricity generated by geothermal energy. Simply put, geothermal systems use two loops to transfer geothermal energy to your home’s heating and cooling system to keep you cozy.


Putting in a geothermal heating and cooling system to your home needs a plan exclusive to your installation. No two projects are alike, which is why it’s essential to get the help of a professional to go through the possibilities with you, from size and cost, to loop choice, digging and installation.

Pond Systems

Installing your geothermal system underground isn’t the only way to get all of its benefits. If you have a pond or lake, a closed loop system can be added near the bottom of your pond or lake and use the regulated temperatures at the bottom to provide you with a comfy home.


The amount of space you need to install a geothermal system will differ based on the lay of your land and the immediate surrounding area. Working with a professional will let you know whether a vertical or horizontal loop is best and they will outline the requirements for your individual project.
