Geothermal Heating and Cooling

>> Jan 5, 2017



Regardless of where you bare in the world, you are experience varying temperatures. For some localities, winters can be brutally cold while areas will always find it hard to believe that temperatures could go beyond zero degrees. This variation is part of what makes the study of climate an enticing mystery.

In the changing temperatures, and without regard to the season, the temperature on the ground remains unchanged. The earth can trap heat in itself and retain reasonably constant temperatures. Even when the area above ground is frozen, the earth will have absorbed at least 47 percent of the sun’s heat to keep it warm enough for human inhabitation. Experts are making use of this knowledge to introduce a way of heating and cooling that is less harmful to Mother Earth.

      Geothermal Heating
The heat from the ground is trapped to heat your home using underground pipes called loops. The loop is installed either horizontally or vertically to enable a transparent exchange of fluids from the ground to the surface. If you get deeper into the ground (beyond 70 feet), you will find pockets of hot water that get even hotter with depth. This heat is sent up through the loop to the surface, where it heats up the foundation of your home or office. When the ground is warmed up, the heat insulates into the building and heats it. This technology is even used to generate geothermal power, which is a renewable source of energy. Your bank account will thank you for being innovative, as you will save at least 80 percent of your energy consumption if you embrace geothermal heating.

      Geothermal Cooling
Geothermal cooling works in the reverse of the heating process. Instead of sending warm air through the loop to the ground and effectively heating your home, the cooling process takes the warm or hot air from the atmosphere and sends it to the ground. The loop either returns the heat to the ground or uses it to heat up water in your hot water tank. At the end of it, you still save some money from the cooling system that will stay turned off for longer and you will not have to use the heater for your water.

How it all works

      Circulation
You have some underground pipes installed beneath the surface of the earth, and you have some more above the ground. The pipes above the ground move water into the pipes buried underneath. The underground water heats up the water in the pipes and circulates the heat all the way from below to the surface of the earth.
      Absorption
As the water goes up the loop, it heats up the rocks that form the foundation of your building.
      Heat Exchange
The heat that the water generates from underground can be put into many uses. You could use it to heat spaces, or you could heat up your water with it. When the surfaces are heated, you will only require minimal amounts of fossil fuel-based energy to heat up the building.
      Recirculation
Once the water has been sent up the loop, it cools down upon contact with the temperatures above the ground. This works well also at times when you use geothermal energy for cooling. The up and down movement works perfectly to keep you comfortable, alternating between heating the surfaces and cooling them.

The use of fossil energy has drained earth of essential elements that we may never recover again. We have spent the better part of their time on Earth ruining it. It does not hurt making some amends. Using a cleaner source of energy could be a great starting point.
