Selecting the right Geothermal System for your needs.
Fluid in the loop
A Vertical loop design is typically used when space is limited as a plastic pipe heat exchanger. Your yard isn’t torn up nearly as much with a vertical loop design. Holes are drilled using a drilling rig, and a pair of plastic pipes with special u-bend fittings which are inserted into the holes. A typical home requires three wells approx. 210 feet deep.Learn More
A Horizontal loop is used where adequate land is available. The ground loop consists of a plastic pipe heat exchanger. Horizontal loops involve one or more trenches that are dug 4-5 feet deep using a backhoe or trencher. A Water/Antifreeze solution circulates through the plastic tubing absorbing the heat from the ground. The ground loop is a key component of the ground source water geothermal system. Therefore many design factors need to be considered to insure the proper installation of a horizontal loop system, be sure to ask your contractor about the design parameters considered for your geothermal loop.Learn More
If an adequately sized body of water is close to your home, a plastic loop can be installed in a pond as the heat exchanger. A Water/Antifreeze solution circulates through the plastic tubing absorbing the heat from the ground. A series of loops can be coiled and sunk to the bottom. A 1/2 acre, 8-foot-deep pond is usually sufficient enough for the average home. The loop design is especially critical with a pond loop system which can lead to system problems if not given proper consideration. Be sure to discuss the loop design of your project with your contractor before staring your project.Learn More
An open loop system system is typically installed in rural areas where it can utilize th 55 degree well water as the heat source for you home.Typically it does not require any outside digging. An open loop geothermal system pumps water from the existing water well through the geothermal unit where the heat is removed from the water. After removing the heat from the water the water remains clean and can be discharged to multiple locations such as; to a running stream, pond, or down a drain. This system typically requires more future maintenance than a closed loop system so be sure to discuss any future maintenance considerations with your contractor.Learn More
The Slinky loop design is another horizontal closed loop design. The plastic heat exchanger pipes are typically laid flat in a circular pattern at the bottom of a trench. A Water/Antifreeze solution circualtes through the plastic tubing absorbing the heat from the ground. This design can save space requiring less land area and shorter trenching when considering installing a horizontal loop. Other design factors should be considered with a slinky loop system, so be sure to ask your contractor about the loop design parameters.Learn More
Comparing Ohio Geothermal Heating Systems
There are three major differences when comparing one Ohio geothermal heatingsystem to another, they are: Loop Type, Loop Design, and the Type of Fluid in the loop. In the winter it collects the earth’s natural heat through a heat exchanger consisting of a series of pipes, made of plastic or copper.
The Loop Material…
The Loop Material can easily be considered one of the most important factors when trying to determine which design is the best investment for you. Currently there are to forms of material used for a geothermal ground loop, they are: plastic tubing or copper tubing. Often the heating contractor will sup-contract the loop system to another contractor and may not actually have the experience installing the loop themselves. So again talking with a contractor who has experience installing both plastic and copper ground loops as well as the rest of the equipment installed inside the home can insure that you’ll make the best decision possible for your circumstances.
