Geothermal Heating and Cooling
Geothermal heating and cooling works by a very efficient process of heat transfer. Geothermal systems do not produce heating or cooling like a standard furnace or air conditioner. Instead, this type of system captures heat and moves it from place to place, making it the most environmentally friendly and cost-efficient way to heat and cool your home.
Since outdoor temperatures fluctuate with the changing seasons, but underground temperatures do not, geothermal systems use a series of fluid-filled underground pipes that absorb solar energy stored in the earth and carries it indoors. In summer, the system reverses, transferring heat from inside and deposits it in the cooler earth. In other words, a geothermal system removes heat from an indoor setting producing a cooler environment, while heating involves extracting outdoor heat and moving it inside to make a home or business warm and comfortable.
The ground loop is such a vital part of a geothermal heat pump system and it must be placed correctly so that it will work at its most effective and efficient level. Depending on the conditions at your home or business, you may find you have to make a choice between a vertical ground loop or a horizontal ground loop. Both types of loop systems work equally well, but the choice between them is usually governed by how much ground space is available for the loop.
A horizontal ground loop is probably the most common of the two, and is installed over a wide area of ground, buried at the optimum level of four to six feet. Horizontal ground loops require a substantial amount of open ground space for installing the pipes. Horizontal ground loops are used in situations where there is plenty of open ground space available for the digging and trenching required to install the pipes. Many rural or suburban homes have adequate ground area for this installation, as do individual commercial buildings that are built on their own plots of land.
A vertical ground loop is installed in holes drilled deep into the ground, usually to a depth of 150 to 300 feet. The loop pipes are placed into these holes, which are typically placed about 20 feet apart.

Which loop is the best?
The least expensive loop that fits on your property.
Which loop is the most efficient?
They are virtually all the same. The loop is designed for your particular application.
How long does the loop last?
The material has a life expectancy of 200 plus years. It’s the same material used in the gas and petroleum industry.
How much land do I need?
Do you own a lawnmower? A 4 ton vertical loop fits in a 15’ x 15’ square feet space.
How deep do you have to bury the loop?
Depends on the type of loop.
- Horizontal loops are buried on an average of 4 to 6 feet.
- Vertical loops are an average of 150 to 300 feet in depth.
What is the ROI – breakeven point?
- ROI – it’s very attractive and out performs the stock market, we would be glad to have this modeled for your particular application.
- Breakeven - based on current tax incentives and BREC rebates, a 3 ton geothermal system will have paid for itself in 7 years. If you are or have to replace your current system, the pay back is typically the first day you own the system.
How much more is a geothermal system than an ordinary system?
If you are comparing geothermal to ordinary high efficiency air conditioning, the upfront could be twice as much. However, with the tax incentives and BREC rebates, in most cases the cost is the same or even less than that of an ordinary system.
How does it work?
Geothermal systems harness the thermal energy in the ground beneath our feet. The ground temperature remains fairly constant year round. No matter if it’s winter or summer. Ordinary air conditioners uses the outdoor air for its heat exchange source which fluctuates tremendously from summer to winter. In our area, it can range from the teens to triple digits.
