We are dealers of the quality line of components by Earthlinked Technology—"simple, small and energy-efficient geothermal systems provide affordable heating and cooling and enable people to hedge against soaring electricity prices, lower their energy bills, reduce their carbon footprint and improve their quality of life."

Reduced fossil fuel consumption, reduced emissions and increased comfort result from the use of renewable stored solar energy stored in the shallow earth. These benefits are delivered by the Earthlinked heat pump system. Almost half of the sun's energy that reaches the earth is stored in the ground, resulting in a solar battery that can be used for heating. The constant and favorable temperature of the earth also makes it a favorable heat sink to receive unwanted heat in the cooling season.

The Earthlinked system has three major components: (1) an earth loop system to exchange heat with the earth via a heat transfer refrigerant that circulates through loops; (2) a heat pump that moves heat or cooling between the building and the earth via the earth loops, and (3) a distribution system to distribute comfort through the building.

The earth loops are like arteries in the human body. The loops are connected to the heat pump to circulate refrigerant and directly exchange thermal energy with the earth. Earthlinked ground loops have the smallest size and smallest footprint in the market. They have the highest temperature differential with the earth, which means they can use the least amount of earth contact to work effectively. The loops can be installed in three different configurations as shown below.

The long lasting loops are made of copper, one of the few metals that exist as an element of the earth. A noble metal, copper resists corrosion because of the protective film that forms naturally on its surface.

Like a pulsing heart, the heat pump circulates the refrigerant through the earth loops to exchange thermal energy with the earth. No complex mechanical equipment is required. Just three mechanically simple devices (a compressor, a condenser and an evaporator) enclosed in a small indoor unit and integrated to work seamlessly, leveraging the natural laws of physics. The system is more reliable and efficient that other geothermal systems because it has no water circulating pump, intermediate heat exchanger or thermostatic expansion valve.

Refrigerant passes through earth loops and exchanges thermal energy with the earth. A uniquely innovative, patented technique enables the control of the flow and stability of the refrigerant without any electronic devices, thereby further improving the efficiency and reliability of the Earthlinked system.

Geothermal Heat Pumps Eligible for Tax Credit of 30%

The American Recovery & Reinvestment Act of 2009, that was signed by President Obama on February 17, 2009, contains long-term tax incentives to homeowners to encourage the installation of geothermal heat pumps in personal residences. The new law, effective January 1, 2009, offers a one-time tax credit of 30% of the total investment for geothermal heat pump installations - without the limit of $2,000 that was part of the law enacted in 2008.
