Geothermal is a renewable energy source which can reduce heating/cooling bills by 40-70%. Geothermal heating uses the Earth’s heat in the winter to heat a home while geothermal cooling uses the Earth’s coolness in the summer to reduce the heat in a home. The loopfields are utilized in order to circulate a fluid in the Earth in order to extract the heat/coolness of the soil. The Earth stores solar energy which allows the temperature below ground to maintain relatively constant. Kleiman Pump and Well Drilling, Inc. has been installing geothermal loopfields since 2008.
A GeoSystem uses solution from a well or from a vertical or horizontal closed loop of pipe burined in the ground. As the ground temperature solution (which contains a suprising amount of energy) reaches the heat pump, its heat is absorbed by a low pressure refreigerant, which tnen vaporizes. The refrigerant is compressed, raising its temperature to 160 degrees Farenheit. Finally the heat energy is released to the air heat exchanger for circulation via ductwork through your church, school, or home. In the summer, the flow of the refrigerant is merely reversed so that heat is drawn from the building and released into the ground.
Vertical Loops are used extensively where land area is limited or soil conditions prohibit digging the more economical horizontal loops. A pair of pipes with a special U-Bend assembly at the bottom are inserted into a bore hole that averages between 150 to 250 feet deep per ton of equipment. These holes are then backfilled with a special grout solution to ensure good contact with the earth.
Horizontal Loops are installed in areas where the soil conditions allow for economical exclamation. Taking up more land area than any other type, they are used were space permits. Trenches are normally about five foot deep with multiple pipes placed in the trench at different depths. Normally, several hundred feet of trench is required, but we’re space permits these loops are considered desirable.
Pond loops are usually very economical to install. If a pond or lake at least eight feet deep is available, pond loops can utilize the water rather than soil to transfer heat to and from the pond. A coiled pipe is placed in the water which should cover about 1/2 acre. And average home would require about 900 feet of pipe. We do see installation cost and high-performance are characteristic of this type of loop.
installations actually pump water from an underground aquifer through the geothermal unit and then discharge the water to a drainage ditch or pond. The geothermal unit processes the heat energy from the water just like a closed-loop installation. Discharging water to a return well sometimes effective, but sending water to a pond or lake is considered more reliable.
