What Are Geothermal Loop Systems? A Geothermal Question

Monday, April 29th, 2013

Geothermal heating and cooling systems allow residents in  New City, NY and surrounding areas to use energy stored in the ground and in water on their property to heat and cool their homes. A geothermal loop system is necessary to harness this energy for use in your home. If you’re interested in using a geothermal system to heat and cool your home in a more efficient, eco-friendly manner, it is important that you understand some basic information about these loop systems. There are a few different designs, and the New City geothermal experts at Design Air will help ensure that you get the right loop system for your home.

Closed Loop Systems

There are three types of ground loop systems – horizontal, vertical and pond/lake installments. Closed loop geothermal systems circulate an antifreeze solution through the closed loop, which is buried beneath the ground or submerged in a body of water on your property. A heat exchanger transfers heat between the antifreeze solution in the loop system and the refrigerant in the heat pump. In a horizontal closed loop system trenches are dug at least four feet deep in the ground. The loop system is installed in these trenches, and a method of looping pipe can allow for more pipe to be installed in a shorter trench.

Vertical loop systems are a good option for schools and commercial buildings, as less land is necessary for installation of the system than with a horizontal option. Holes are drilled into the ground, and pipes are inserted into these holes and connected at the bottom to form a loop. The drilling necessary can increase the cost of installation.

The cheapest option for a closed loop installation is generally a pond/lake loop system. An adequate body of water meeting certain volume and depth requirements is necessary. A supply line is run underground and submerged at least 8 feet underwater in coils.

Open Loop Option

If there is a suitable water supply on your property you may opt for an open loop system. With an open loop water itself is used as the heat exchange fluid. Water is circulated throughout the system and, when it has completed circulation, it is returned to the ground. Local codes and regulations may inform the suitability of this option.

We hope that this information has been helpful. At Design Air we believe consumers should be informed. If you have any other questions about geothermal loop systems, contact a professional at Design Air today.

Geothermal Installation Process: A Heating Guide

Monday, April 1st, 2013

More and more homeowners in New City are starting to realize the benefits of geothermal systems. At Design Air, Inc., we offer complete geothermal system installation and repairs in New City. We’ve been working with many customers to help them start realizing the efficiency gains that geothermal systems offer. We often get asked about the installation process for geothermal systems. We thought it would help clear up some misconceptions if we put together a quick description of how the geothermal heating and air conditioning system installation process works.

How Geothermal Heating and Air Conditioning Systems Work

If you were to dig down into the ground about 10 feet, the temperature there would be about 55° F. It stays that temperature all year long—no matter what the temperature of the air is above it. Geothermal systems use that energy to heat and cool your home. To do that, a long series of pipes need to be buried in the ground and filled with a refrigerant.

Space Restrictions

Geothermal loops can be installed vertically or horizontally. However, these space restrictions make geothermal systems impossible for homeowners whose property isn’t large enough to accommodate the coils.

The Heat Pump

After the coils have been buried in the ground, they are hooked up to a heat pump in your home. The heat pump circulates refrigerant through the coils where it absorbs heat from the ground. The refrigerant carries the heat into the heat pump where it is extracted and circulated through your home in the duct work.
