Sapona Green Building Center is hosting a free evening event about Geothermal energy from 5pm-6pm on Thursday September 18th. The event will be at their show room in Anderson Sq, 4113 oleander dr. Wilmington, NC.
Speaking will be Paul and Bryan Donaldson representing WaterFurnace, makers of some of the most efficient, energy-saving heat pumps available.
Wherever you live, whatever time of year the temperature below ground stays fairly consistent all year. Geothermal systems tap into the free energy of the differential between air and ground temperature using an earth loop (pictured).
Geothermal systems use the earth loop to extract heat from the ground. As the system pulls heat from the loop it distributes it through a conventional duct system as warm air or it can be used for a radiant floor system or domestic hot water heating.
In its cooling mode, a geothermal system reverses the process extracting heat from the building and back into the earth loop, or used to preheat water in your hot water tank.
