How Geothermal Works

 

We all know that Northern Colorado homes are acceptable to varying temperatures during the year. Some climates can see the extremities that summer and winter hit us with. There is a consistent source of temperature that you can put to good use; just a few feet underneath the earth’s surface. How is that possible?

The sun imparts the Earth’s crust with its heat energy. Forty-seven percent of that energy is stockpiled in the ground as heat. WaterFurnace geothermal systems extract this heating potential using an earth loop system; harvesting this free heat for your home. This cutting-edge technology uses the sun’s heat that the earth has conveniently stored to condition your home or office.

GEOTHERMAL

A geothermal system is very similar to a heat pump but on a much larger scale. How it works, is that it heats cold homes, and commercial buildings via the heat from the earth, and cools these same buildings during warm weather by removing the heat and replacing it back into the earth. A strange concept to grasp, but it is one that has been proven to work! There are four types of geothermal systems that we offer, and all have been deemed to be some of the most efficient ways to reduce both residential and commercial energy bills.

Those include:
  • Open Loop – which uses existing ground water as a heat transfer medium.
  • Pond Loop – which uses water is nearby ponds/lakes to absorb and gather heat
  • Horizontal Loop – which uses a heat transfer tube that extends out instead of down
  • Vertical Loop – which uses heat transfer tubes that extend directly down

Geothermal Heating

Using the earth loop, a WaterFurnace geothermal heat pump pulls the heat from the ground in the heating cycle. The geothermal system draws the heat from the loops and delivers this warmed air through a standard duct system. Additional options include using that same heat to provide hot water and radiant floor heating are available.

Geothermal Cooling

In the cooling mode, the heating process is reversed – creating cold, conditioned air throughout the home. Instead of extracting heat from the ground, heat is extracted from the air in your home and either moved back into the earth loop, or used to preheat the water in your hot water tank.
