How Geothermal Works

We all know that Baltimore homes are subjected 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 utilize; just a few feet underneath the earth's surface. How is that possible?

The sun permeates the Earth's crust with its heat energy. Forty-seven percent of that energy is cumulated 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

During the heating cycle, a WaterFurnace geothermal heat pump uses the earth loop to draw heat from the ground. As the system pulls 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

During the cooling mode, cool, conditioned air is circulated through the house by reversing the heating process. Heat is not pulled, instead it is driven into the ground. The warm heat is pulled from your home and transferred back into the earth loop. Your hot water heating can be fueled by this procedure as well.
