Most people say they do not have enough ground for a geothermal loop, but you would be surprised at the small amount of space actually needed for a geothermal ground loop. You are probably sitting in a room right now typing on your computer, and the room is probably at least 10' by 10' square. If you are not sure, stand up and take three large steps. This would be a length of about 10' also. In that amount of space we can install a four ton geothermal ground loop that would heat a 3000 sq. ft. home and maybe even bigger depending on the type of construction. Now go out in your yard and step off a 10 x 10 area. That is where we would install your loop that could save you thousands of dollars throughout the years.
Actually there are many different types of loops that can be installed depending upon the area you have available. Some loops are more economical to install than others, however from the least expensive to the one that costs the most you are only looking at a difference of about $300 per ton. Lets take a look at the different loops that are available and what space is needed for each one.
- The single pipe loop system
One single pipe that can snake throughout the yard or even wrap entirely around the home.
A very narrow trench with the pipe going out at 5' or 6' deep and returning at 3' or 4' deep. Usually 2-6 trenches are needed about 8-10' apart and 250-300' long.
This loop consists of about 2-6 trenches 5' deep, 3' wide and 125-145' long. This is the most common loop used today and is also the most efficient being entirely at the 5' depth level. The trenches should be about 10'-12' apart.
The pond loop slinky was actually developed by a geothermal pioneer in Mansfield, Ohio. Jim Gahring was the first nationwide to install the slinky pond loop and from there it was tested and certified by The International Ground Source Heat Pump Association in Oklahoma. Check with your geothermal specialist to see if your pond is large enough to support a geothermal system for your home. The slinky pond loop takes up an area in your pond about 12' X 30'.
The vertical loop can fit almost anywhere. If you have a 10' X 10' square area of grass then you have enough room to install a geothermal system. Even if you don't have grass, we can install it under the driveway or parking lot of a business.
There are many open loop systems throughout the Ohio area. If you have a well and the water is within the parameters we require, you may be able to install a ground water geothermal system otherwise known as the open loop system. In addition to the water condition requirements, you also must have enough water available and a place to dispose of the water. Keep in mind that we are not wasting the ground water, just taking the temperature from the water and returning it to the hydrologic cycle.
