the earth below the frost line
Paducah, KY (PRWEB) March 20, 2009
A new era of home comfort has arrived with the low cost of geothermal heating and cooling equipment. While the name may sound space-age, the technology is very down to earth. Ingram's Water and Air Equipment can show you how you can heat and cool your home and significantly lower your energy costs using the natural heat storing ability of the earth
How does it work? A geothermal heating and cooling system, sometimes called a ground source heat pump, works on a simple premise: "the earth below the frost line" (usually about four feet down), is a constant temperature of about 50 degrees year round. During the winter, heat can be taken from the ground and transferred through a heat pump to the air in your home. Heat can also be transferred back into the ground during summer to cool your home.
This great technology will provide you with lower energy bills. Heat from the ground is free, and the only electricity needed is for moving that heat between your home and the ground. A geothermal system can lower your heating bills up to 50 percent and cooling bills up to 30 percent! This could mean a payback in as little as two to five years and when considering the federal geothermal tax credit of 30% of qualified expenditures with no maximum limit; the payoff is shortened even more.
A common and cost effective geothermal installation method is to use an open loop or "well water design system." In this method a well supplies both household water and water for the heat pump. Approximately 2-3 gallons per minute of well water are needed per ton of cooling capacity, and a 3,000 square foot, well insulated home would typically require 10 to 15 gallons per minute when in use. In an open loop system ground water is usually supplied to the heat pump by a drilled well with a submersible pump system. If a recharge well is to be used, it should be drilled at the same time as the primary well. When the thermostat calls for heating or cooling the slow closing solenoid valve opens to allow the water to flow thru the water coil in the heat pump. The clean discharge water is normally piped to a creek, pond, or recycled. Ground water should be tested for acidity, dissolved solids and mineral content. Normally the supply water is tapped straight off the bladder tank from the well, and shut off valves and flow meters are used to accurately meter the supply water to the heat pump.
