Understanding Geothermal

In today’s world, it seems that one aspect is trying for ways in which to decrease our “footprint” and the opposite facet is somewhat ambivalent concerning energy and the implications that arise from our ever increasing hunger for energy. You definitely don’t have to be labeled a “Tree Hugger” to care regarding the surroundings and conserve our natural resources. With this in mind, let’s take a nearer look at geothermal energy and the way this amazing resource that has been around since the start of time is making its method to the forefront of recent society.

To begin, geothermal energy is simply the Earths heat that naturally occurs underground. There are three categories of this energy, electrical power generation, direct heating & geothermal heat pumps; this article will target the latter. As we all recognize, the Earth’s temperature rises gradually with depth, culminating at 7600º F at the inner core. After all we’re not looking to faucet into heat sources at seventy 600 degrees, however just below the surface of the land that surrounds your business or home, is an endless & sustainable offer of energy to heat and cool your building.

There are a pair totally different geothermal systems, the first being open loop. An open loop system utilizes a lake, pond or underground aquifer because the heating or cooling source; the open loop system can be used if your structure is found shut to at least one of these. Next is that the closed loop system, which, because the name implies is closed and uses a combination of water and environmentally friendly antifreeze that’s enclosed in the system. There also are horizontal & vertical loop systems which can be explained shortly. Let’s take a closer take a look at how geothermal heating and cooling systems work for commercial & residential applications. In a closed loop vertical system, that is most prevalent for residential applications, a system of pipe is buried in the property surrounding the structure and a series of holes are dug for the pipe. Relying on the location, the pipe will run from anywhere between one hundred and three hundred feet.

The water/antifreeze mixture is then pumped through the pipe system and in turn the geothermal energy of the ground heats the mixture during the winter time for a heating result or removes the heat from the mixture throughout the summer time for a cooling effect. In a horizontal loop system, the same principle applies, except that the pipe is buried at a abundant a lot of shallow depth and therefore the pipe system runs horizontally to ground level, therefore requiring a bigger footprint of land to install the system. That is why vertical loop systems are abundant additional prevalent in higher density areas. A further profit is that the heating result geothermal will add for your domestic water needs. Sometimes, the system will lower your water heating bills by 35%!

With the demand for fossil fuels skyrocketing from rising industrial countries like China, energy prices can be rising until the demand levels or starts to decrease. Geothermal energy is a real answer to reducing our dependence on these fuels and isn’t a technology you have got to wait for the lots to implement. Of course the initial installation costs are more than standard heat pump systems, however the savings on energy prices over the lifetime of the system way outweigh the initial costs.

Currently I’ll answer your question concerning longevity. A geothermal lifetime averages 22 years, which is about 7 years longer than a standard heating & cooling system. The system has a further benefit similarly; less moving components equal less things to break and less maintenance.
