Geothermal Systems

Use the power of the earth to heat and cool your home.

According to the Department of Natural Resources (DNR), homeowners using a Geothermal system save an average of 30-60% off their monthly energy bills when compared to a conventional system.

Like our company, the basic technology has been around for a long time, and many homeowners and businesses have been enjoying the benefits of geothermal heating and cooling for much of that time.

In recent years, though, significant improvements have been made in the materials used, installation methods, electronic control systems, and the efficiencies of the compressors, pumps, and other equipment.

How Geothermal Heating Works

Geothermal heating simply pumps heat from the earth into your home. A liquid is circulated through a large loop(s) in the ground called a ground loop.

While that liquid is traveling through the pipe buried in the ground, it absorbs the heat from the surrounding ground.

That liquid then carries the heat to the heat pump, which acts similar to a refrigerator in taking that heat through a refrigerant cycle inside the heat pump, and discharging it to your home heating distribution system (forced air or radiant floors).

How Geothermal Cooling Works

Geothermal cooling works the same as geothermal heating, except in reverse. Heat is taken out of the structure in the home, put into the circulating liquid inside the ground loop, and absorbed into the cool earth.

This “reversed” cycle is simple to switch a heat pump into with its reversing switch. When a ground source heat pump is in cooling mode it is functioning the same as a refrigerator, pulling heat out of the house, putting it through a refrigerant loop, and then expelling it out.

A refrigerator does that using the coils on the back. A groundsource heat pump does it using the large earth loop and cool mass of earth, making it more efficient to have heat go to cold instead of hot ambient air.

How Geothermal’s Good for the Environment

According to data supplied by the U.S. Department of Energy (DOE) Office of Geothermal Technologies, nearly 40% of all U.S. emissions of carbon dioxide (CO2) are the result of using energy to heat, cool, and provide hot water for buildings. This is about the same amount of CO2 contributed by the transportation sector.

A typical 3-ton residential geothermal system produces an average of about one pound less carbon dioxide (CO2) per hour of use than a conventional system. To put that in perspective, over an average 20-year lifespan, 100,000 units of nominally sized residential geothermal systems will reduce greenhouse gas emissions by almost 1.1 million metric tons of carbon equivalents.

That would be the equivalent of converting about 58,700 cars to zero-emission vehicles, or planting more than 120,000 acres of trees.

And the waste heat removed from the home’s interior during the cooling season can be used to provide virtually free hot water-resulting in a total savings in hot water costs of about 30% annually, and lowering emissions even further.

How Geothermal’s Good for Your Budget

While they sometimes cost more to install in homes than conventional systems because of the ground loop piping, Geothermal systems typically have the lowest life-cycle cost of any heating and cooling system. Heating and cooling costs for a typical 2,000-sq.-ft. home can run as low as $1 a day.

Moreover, installation costs have declined substantially in recent years, and they’re expected to continue to fall as more builders and contractors offer geothermal systems, and as the industry develops innovative ways to install the systems faster and more efficiently.

Altogether, geothermal systems are a sound investment. The amount they save the homeowner every month in energy costs is more than enough to offset their higher installation cost.

Remember, too, that geothermal means extra savings on repair, maintenance, and hot water bills.

Furthermore, the energy efficiency of the system adds value to the home. The National Association of Realtors Appraisal Journal estimated that a home’s value increases by $10 to $25 for every $1 reduction in utility bills. That’s a lot of equity to build just by choosing geothermal.
