The need for renewable resources keeps rising. Eventually, reserves of coal and natural gas will be very low. There are many things that can be done to reduce the need for conventional sources of energy. Two of the more popular ways on the market today are solar power and wind power. But there is another way to reduce the need for utility companies and that is geothermal.
Geothermal harnesses the energy of the earth to heat and cool a house. It is the commonest means of cooling in data centers. Data centers hold a lot of temperature sensitive equipment that needs to stay cool enough to not overheat. Geothermal cooling proves to be an economical and environmentally safe way of cooling large spaces.
The same is used in residential homes in order to save homeowners money on their utility bills and to have less of an impact on the environment. It is estimated that a geothermal system saves homeowners between 25% and 50% on their utility bills. The percentage varies by location. More extreme temperatures see a larger impact on the utility bills. For example, Florida and Texas in the South see a larger difference in the cooling aspect of the system; Minnesota and Michigan in the North see a larger difference in the heating aspect of the system; while, Missouri and Illinois in the Midwest see a decent impact on both heating and cooling.
Geothermal Cooling System Services Wildwood MO harnesses the temperature of the ground to help cool the house. When going down deep enough, the temperature underground is a constant temperature. Typically, the depth between five and ten feet is at a steady temperature of 72 degrees. The constant temperature is slightly different than 72 degrees depending on the geographic locale but that is a common average.
In order to harness geothermal energy, pipes are buried in the ground where the temperature is constant. Lots of pipes are buried and usually snaked back and forth across a property to accommodate enough area to be efficient. Lots of pipes have to be used because as the ground cools or warms the contents of the pipes, the more surface area the ground touches, the more efficient the system is.
Liquid, usually water, is pumped through the pipes underground and into pipes in the house. As the liquid goes through the underground pipes it either cools down or warms up depending on the temperature of the house. If the indoor temperature of the house is below 72 degrees, then the liquid warms up. If the indoor temperature of the house is above 72 degrees, then the liquid cools down.
The process takes very little energy from the utility companies to run. If the constant temperature from the system is not comfortable enough, it can be coupled with conventional heating and cooling methods and still drastically reduce utility bills. It is a little costly up front, but it pays for itself in four to seven years depending on the geographic locale. Once installed, the system should last between 25 and 30 years.
