How Geothermal Works

The temperature throughout the year will always vary no matter what climate you live in. For some climates that means blazing summers that cool to freezing winters, and Mountain Home is no exception. What many people don't realize 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 hits 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 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 draw heat from the ground. As the system draws heat from the loop it distributes it through a conventional duct system as warm air. The same heat energy can also be used for a radiant floor system or domestic hot water heating.

Geothermal Cooling

In the cooling mode, the heating process is reversed - creating cool, conditioned air all through 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.
