North Carolina homeowner cuts bills in half with geothermal heat pump
Chad Harrell was adamant. His new home would feature a geothermal heat pump system.
So after moving to North Carolina from London in 2012, he set his sights on a large home. He found one in a historic district not far from downtown Raleigh, a 100-year-old structure in considerable need of renovations.
Harrell’s goal was to make the home as efficient as possible. He started by outfitting it with solar panels and high-efficiency windows and doors. Then, working with general contractor Greg Paul Builders, he strove to incorporate a retrofit geothermal heat pump system.
What initially seemed an insurmountable task, due to the small size of the home’s back yard, became reality by relocating the borehole sites to the front yard. The boreholes eventually connect to a ClimateMaster 2.5-ton Tranquility 22 Digital (TZ) Series and a Tranquility Digital Indoor Split (TES) Series heat pump unit in the home’s basement and attic.
Louis Agnolutto, owner of Louis Heating & Cooling Inc. who installed the system, said the ClimateMaster units were logical choices for the project. Not only for their quality, but also because the units are easily customizable to fit the energy needs of clients.
ClimateMaster makes “a good basic unit,” he said. “The cabinetry is sound and solid. The equipment and parts are proven.”
In the year since moving into the North Carolina home, Harrell estimates his energy savings at about 50 percent of that for which his neighbors pay each month to operates homes of similar size.
“I want to put up a sign in the front yard that says, ‘Renewable energy: At work under your feet,’ ” he said.
