Residential Systems: The Energy Wise Way to Live

Residential Systems: The Energy Wise Way to Live

Whether you’re building a new house or considering a new heating and cooling system for your present one, consider the economical and environmental advantages of geoexchange technology. It is the world’s most advanced, most cost-efficient heating, ventilating and air conditioning (HVAC) system for a new or existing home.

Geoexchange is an increasingly popular choice, especially for new home construction, but it’s as old as the earth itself. By tapping into the relatively constant temperature of the earth below the frost line, geoexchange heats and cools your home at significant savings — 25% to 50% savings when compared with traditional systems.

Geoexchange technology also offers you greater levels of home comfort and control. A lot less maintenance. Enhanced home resale value. And the endorsement of the US Department of Energy (DOE) and the Environmental Protection Agency (EPA). So read on. The more you learn about geoexchange, the more comfortable, cost-efficient and environmentally conscious your home can be.

All of the comfort of home, out of the ground.

Geoexchange is a simple technology that uses the earth’s renewable energy to provide high-efficiency heating and cooling. In winter, the system draws heat from the ground and transfers it to your home. In summer, it extracts heat from your home and transfers it to the ground. Hardware consists only of a heat pump connected to a series of small-diameter pipes buried underground. A water solution circulating through the pipes carries heat between the ground and the heat pump.

The highest efficiency of any HVAC system.

There isn't a single more efficient HVAC technology than geoexchange. Oil and gas systems require fuel for heat and a separate air conditioning system for cooling. Geoexchange provides both in one system. The EPA confirmed the superior efficiency of geoexchange, finding that even on a source fuel basis — accounting for all losses in the fuel cycle including electricity generation at power plants — geoexchange systems average 40% greater efficiency than air source heat pumps, 48% greater efficiency than gas furnaces, and 75% higher efficiency than oil furnaces. Today’s best geoexchange systems outperform the best gas technology, gas heat pumps, by an average of 36% in the heating cycle and 43% in the cooling cycle.

The Best Environmental Choice

Preserving natural beauty and resources. There are many other reasons why geoexchange is your best choice for home heating and cooling. Chief among them: minimal environmental impact.

No one would ever guess there’s a heating and cooling system in your yard. Geoexchange preserves the natural beauty of your property. The network of pipes can be hidden under your lawn, a garden, even your driveway.

The geoexchange unit is also out of sight — housed inside, protected from the weather. The sealed pipes circulate water or a non-toxic solution of water and anti-freeze that never comes in contact with the earth. And, unlike traditional technologies such as gas, oil and propane, geoexchange produces no combustion or smoke. That helps lower greenhouse gases, carbon dioxide and sulfur dioxide emissions into the atmosphere, as well as pollution concerns over storage tanks in-ground.

Geoexchange systems significantly reduce our dependence on the earth’s finite supply of fossil fuels, and help keep our blue skies blue.

Inside, an atmosphere of peace and quiet. Living with a geoexchange system is an exceptionally quiet and comfortable experience. No noisy furnace. No fuel lines in your home. No worries about soot, fumes or carbon monoxide, either. Geoexchange systems offer unsurpassed indoor air quality, operate as quietly as a refrigerator, and are so compact they can be installed in an attic, basement, or small closet.

Two Kinds of Geoexchange Systems.

The most common geoexchange system, a closed loop, circulates water or a mixture of water and non-toxic antifreeze through a continuous loop of sealed pipes buried, vertically or horizontally, under your property.

An open loop system also uses pipes, but draws water directly from a well, nearby lake or pond. The water is then pumped through a heat exchanger, which extracts the thermal energy and then returns the water to the source.

Both closed and open loop systems use heat pumps to transfer thermal energy into your home and deliver it into individual rooms via heat ducts. In the summer, the system works in reverse. Return air vents remove hot air from each room and send it to the heat pump, which transfers the excess heat back to the earth where it dissipates underground.

Other types of geoexchange systems include standing column wells, community loops and hybrid systems.

At Home in All Types of Houses

Many builders are familiar with geoexchange heating and cooling. If yours is not, s/he will be pleasantly surprised to learn that the technology has been around since the 1940s. And that it has proven itself over many years in hundreds of thousands of homes, commercial buildings and offices, hospitals, schools and universities.

Geoexchange systems are found in all types of housing, from luxury and middle-class homes, to townhomes — even in Habitat for Humanity homes. Initial system costs have declined to where they are on par with traditional systems. More builders and heating and cooling contractors are making geoexchange technology available. And innovative installation techniques are also enabling them to install ground loops more quickly (often in one day) and for lower costs.

Less complexity, more comfort. It's easy to understand and appreciate the technology behind geoexchange heating and cooling. It employs basic plumbing equipment — pipes, pumps, valves, heat exchangers, fans and compressors. Routine maintenance consists of changing the air filters. There’s no furnace or chimney to clean. And since there’s no flame, geoexchange systems operate at lower temperatures, which helps the components last longer. The underground pipes, for example, are warranted by some manufacturers for up to 50 years.

We have available several brochures, case studies and videos to illustrate how a geoexchange system can provide you with an economical, environmental, and comfortable solution to meet your heating and cooling needs. Contact us to determine the system that best suits your needs.
