How Geothermal Works

We all know that Portland, OR 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 beneath 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 draw from 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 readily accumulated to condition your home or office.

Geothermal Heating

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

Geothermal Cooling

In the cooling mode, the heating process is reversed - creating cold, 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.
