How Geothermal Works

The temperature throughout the year will always vary no matter what climate you live in. For some climatic zones that means hot summers that cool to frigid winters, and Kalkaska is no exception. What most people don't understand is that the temperature underground (regardless of climate or season) stays pretty consistent year round.

The ground is able to maintain a higher rate of constant temperature because it absorbs 47% of the sun's energy (heat) as it impacts the Earth's surface. WaterFurnace geothermal systems are able to draw from this free energy with an earth loop. This technology is then utilized to provide your home or office with central heating and cooling.

Geothermal Heating

In the heating cycle, a WaterFurnace geothermal heat pump utilizes the earth loop system to extract the heat from the ground. With delivery through a conventional duct system, the geothermal system draws heat from the loops and circulates it as warm air. Other choices are available to use that same heat energy to provide hot water heating and radiant floor heat.

Geothermal Cooling

The heating process is reversed in the cooling mode - creating cool, conditioned air throughout the home. Instead of pulling 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.
