With rising energy costs many homeowners are asking if geothermal energy could be a more cost effective way to heat and cool their Pennsylvania home. Geothermal heating and cooling offers many advantages over conventional electric, gas and oil based systems, but also has a few disadvantages.
Geothermal is not a new technology, it operates on the principle of heat exchange and the fact that the temperature underground is a relatively consistent 55F. Pipes are installed underground to circulate water throughout the ground. The water returns to an energy pump inside the home which uses the temperature difference to extract the energy from the water.
During the hot summer months, cooling with 55F water is more efficient than with a conventional AC condensor using electricity to chill 90F air. During the cold winter months, making heat from 55F water is far more efficient than heating 15F air with conventional fuels.
Disadvantages of Home Geothermal SystemsThe main disadvantage of residential geothermal systems is the up front cost. Depending on the conditions for drilling the average residential geothermal energy system will cost $10,000-$20,000. It's an investment that can take 5-10 years to pay off.
Another disadvantage is the geothermal pump needs a conventional power source, although it uses minimal amounts of energy.
Advantages of Home Geothermal SystemsThe main advantage of residential geothermal systems is it's a truly renewable energy source that will never run out and is virtually cost free. Geothermal is also among the greenest ways to heat and cool your home, with an extremely small carbon footprint.
Geothermal energy is also extremely reliable. Because the temperature of the ground will be very consistent, energy costs and output will be reliable from the minute the system goes online and for many years down the road. Compared this to the variability of wind and solar energy and even fossil fuels which can fluctuate in price dramatically, geothermal is a safe bet for home energy savings.
