Geothermal System Types From, left to right - Pond Closed Loop System Horizontal Closed Loop System Vertical Closed Loop System Not shown is an open loop system Geothermal heating and cooling help contractors qualify for the Energy Star Home designation. A geothermal system has 400 percent efficiency rating on average. Energy Star Homes use at least 30% less energy than required by the Model Energy Code while maintaining or improving indoor air quality. A more efficient Energy Star Home simply costs less to own and operate and is strongly positioned for high resale value and easy access to preferred mortgage financing. Horizontal, Vertical, Pond, and Open loops If a horizontal loop system were installed, it would involve the excavation of parallel trenches, each 5 feet deep and 3 feet wide and about 130 to 150 feet long. The minimum distance between each trench is about 15 feet. Each parallel trench can run in any direction; that is they don´t have to be side by side. 600 feet of 3/4 inch polyethylene pipe are placed in each trench resembling a slinky laid flat on the bottom of the 3 foot wide trench. All parallel trenches are connected to a 1 1/4 inch supply and return header which enters the house through the basement to the geothermal flow center. Alternative horizontal loops use 2, 4, or 6 pipes per trench. A 2 pipe trench would be about 1 to 2 feet wide and about 400 feet long. As more pipe is added to the parallel loops, the length of the trench is reduced. The vertical loop would involve vertical bore holes 4 inches in diameter drilled about 150 feet each. Each bore hole would be separated from the next by about 10 feet. Two 3/4 inch polyethylene pipes are inserted into the 150 foot bore hole. The pipes are connected at the bottom using a U-bend. The bore hole is then filled with bentonite clay to bond the pipe to the earth and prevent surface water from entering ground water aquifers. The individual wells are joined to a 1 1/4 inch header at a depth of 5 feet below grade. The supply and return header then enters the house through the basement wall. A pond loop system consists of 300 foot coils of 3/4 inch polyethylene pipe circuited in parallel via 1 1/4 inch polyethylene header pipes. The header and coil assembly is mounted to a PVC frame which holds the coils at the proper spacing and depth allowing water to flow underneath and through the center of each coil. Concrete blocks are attached to the base of the PVC frame and the entire structure is floated to the desired location in the pond. Once in position the pond loop is flushed and filled from the basement through 1 1/4 polyethylene header pipes sinking the pond loop to the bottom of the pond. Where ground water is abundant, a water well can also be used as the energy source/sink, reducing the installed cost by eliminating the closed loop. However, a return well or acceptable surface discharge is required. In addition, an open loop system will require periodic cleaning of the heat exchanger to remove mineral deposits. This is generally done annually.
