How Geothermal Works

The temperature throughout the year will always vary no matter what climate you live in. For some climatic zones that means blazing summers that cool to ice-cold winters, and Lane County is no exception. What many people don't understand is that the temperature below ground (regardless of climate or season) stays pretty consistent year round.

The ground is able to sustain a higher rate of temperature consistency because it takes in 47% of the sun's energy (heat) as it impacts the Earth's surface. WaterFurnace geothermal systems are able to extract this free energy with an earth loop. This technology is then used to equip your home or office with central heating and cooling.

Geothermal Heating

During the heating cycle, a WaterFurnace geothermal heat pump uses the earth loop to extract heat from the ground. As the system draws heat from the loop it circulates it through a conventional duct system as warm air. The same heat energy can also be put to use for a radiant floor system or household hot water heating.

Geothermal Cooling

Conditioning air is just the reverse process used in the heating cycle. Warm air is pushed by the geothermal heat pump into the ground. By removing the warm air, all that is left is cool air circulating throughout your home. There is no cost to heating your water during this process.
