Geothermal WaterFurnace Installation in Reading


Essig Plumbing and Heating is proud to carry geothermal WaterFurnace systems in Berks County, PA. These systems use the renewable energy found in your backyard to bring comfort to not only your home, but your pocketbook as well – saving you as much as 70 percent on your heating and cooling costs.


Geothermal Heating and Cooling

As the seasons change, temperatures outside obviously fluctuate. However, the temperature remains relatively constant just a few feet underground. A WaterFurnace geothermal system circulates fluid through loops buried six feet under the surface where the temperature is stable. These pipes bring warm air into your home in winter and cool air into your home in summer. They use the earth to provide comfort to your home without having to burn fossil fuels to manufacture warm or cold air.


Geothermal Heating

In the winter, the system circulates fluid through the loop of underground pipes, absorbing heat energy from the earth. This fluid is sent to the WaterFurnace heat exchanger, which absorbs the heat from that fluid and distributes it through your ductwork in the form of warm air.

The heat exchanger picks up heat energy in the form of refrigerant gas and moves it to the compressor, where the temperature rises to about 160 degrees. The compressor returns the superheated gas to the exchanger, where the heat pump circulates air across coils. This is the warm air that circulates through your ducts.

Once the warmth is taken from the fluid, that fluid (which is now cold) returns to the loop to absorb more heat and the process repeats itself. These “loop systems” are comprised of small diameter, polyethylene pipes. They can be installed either vertically or horizontally, or even in a pond. Regardless of the outdoor temperature, the stability of the underground earth temperature provides consistent comfort all year.


Geothermal Cooling

The WaterFurnace system basically works the same way to cool your home. The fluid flowing through the loop system is warmer than the ground that surrounds it. This causes the fluid to release its heat energy and become cool. When the fluid gets to the heat exchanger, the compressor once again heats the fluid and returns it to the loop.

The refrigerant inside the compressor is now cold, and is ready to move to the heat exchanger. Inside the exchanger, the blower of the heat pump moves warm air from inside the home across the cold air coil, and that cold air is circulated through the ducts.
