GAITHERSBURG, Md. (WUSA) -- Energy from the ground up! That is what homeowners are looking for when they have geothermal energy systems installed in their homes.
This green technology recycles heat from hundreds of feet below the ground straight into the home. Two wells are placed 300 to 400 feet into the ground. Pipes filled with an antifreeze solution transfers heat back and forth from the wells underground into the house.
In recent years, the rise in energy costs sparked a new interest in geothermal systems from homeowners.
Ted Evans of Ground Loop Geothermal Heating and Cooling says, "Five years ago probably 80 percent of our work was new construction work, now with the cost of energy and everything going up we are probably more of 70-75 percent retrofits now taking old systems out for people to save on their utility bills."
Jon Fuller of Fulton, Maryland is replacing his old furnace with a geothermal system, he hopes to save more than a few bucks on his energy bills.
Fuller says, "A real cold month like in January, that could easily be $1000 a month in oil."
"I'm expecting a nice savings, i'm looking forward to that", adds Fuller.
Gary Mrenak and Sharon Rentzel of Gaithersburg are pleased with the geothermal system they installed in their home two years ago.
Mrenak says, "We were experiencing an average of about 2400 kilowatt hours per month, after the heat pump its about 1800 kilowatt hours per month."
"So for us its been about 25 percent savings", adds Mrenak.
Homeowner tax credits did not expire at the end of 2010 for geothermal. They don't expire until 2016. There are state and federal incentives for homeowners who want to go geothermal.
Evans says, "Geothermal will heat your home, cool your home, and make free domestic hot water for you."
"The ground is doing the heating and cooling, there's nothing outside that's releasing the carbon to disturb the carbon footprint in the area... its very green and very envrionmentally friendly", adds Evans.
