Geothermal Heating and Cooling

The solution to all of your heating and cooling energy needs potentially can be found in your own backyard!

The change of seasons creates fluctuating temperatures both outside and inside your home.  In contrast, heat energy from the sun is absorbed by the earth at a rate of 47%, causing the ground under the earth’s surface to maintain a constant temperature all year long. An efficient geothermal system circulates a water-based solution through loops buried under the earth’s surface where the temperature is stable. This system has the ability to provide hot and cold air as well as some hot water to your home, eliminating anywhere from 30% to 70% of your monthly utility bills.

Product Highlight: Appleton Campbell is proud to offer Water Furnace and Carrier Geothermal Systems. We service all makes and models. We honor all manufacturers' warranties. 

Geothermal Heating and Cooling Works on Three Basic Principles:

• The top level of the earth’s surface maintains a relatively moderate temperature all year long.
• During cold months the system takes the relatively warmer temperature from the earth and uses it as heat for your home.
• During hot months it replaces the hot air in your home with cool air from the earth.

In other words, geothermal systems use the earth’s stable temperature to create a comfortable environment for your home without having to manufacture hot and cold air.

Geothermal Heating

The system begins by circulating water through the earth loop where it absorbs heat energy from the earth. The now warm water is then sent to the heat exchanger where refrigerant absorbs the heat from the water.  The now cold water returns to the earth loop to pick up more heat energy.

The heat energy picked up by the heat exchanger is now in the form of refrigerant gas and travels from the heat exchanger to the compressor.  In the compressor the temperature rises to 160 degrees. The now superheated refrigerant gas travels to the heat exchanger where the heat pump’s blower circulates the air across an air coil. This increases the temperature of the air which is then blown through ductwork and circulated through the home in the form of hot air. After the refrigerant has released the heat energy, it flows back to the earth loop exchanger to start the process again.

Geothermal Cooling

The system for cooling works much the same way. The water circulating in the earth loop is warmer than the surrounding ground causing the water to release energy and become cool.  It flows to the heat exchanger inside the heat pump. There the compressor releases heat energy into the water and the water returns to the ground.

The refrigerant inside the compressor that just released the heat energy is now a cold liquid and travels to the heat exchanger.  Here the heat pump’s blower circulates warm, humid air from the home across the cold air coil. This process creates cold air which is then sent throughout the home.  The refrigerant in the air coil picks up the heat from the air, takes it to the compressor and then to the earth loop heat exchanger to start the process over again.
