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 Medina is no exception. What most people don't realize is that the temperature below ground (regardless of climate or season) stays pretty consistent year round.

The ground is able to retain a higher rate of temperature consistency because it takes in 47% of the sun's energy (heat) as it hits the Earth's surface. WaterFurnace geothermal systems are able to tap into this free energy with an earth loop. This technology is then used to provide 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 draw 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 utilized for a radiant floor system or household hot water heating.

Geothermal Cooling

During the cooling mode, cold, conditioned air is distributed throughout the house by doing the exact opposite as the heating process. Heat is not extracted, instead it is driven into the ground. The warm heat is pulled from your home and moved back into the earth loop. Your hot water heating can be fueled by this procedure as well.
