DUFFY'S GEOTHERMAL

What is Geothermal?
Geothermal Systems utilize the fairly constant ground temperature below the frost line. In the winter, the ground is warmer than the air, whereas in the summer, the ground is cooler than the outside air. This can be used to your advantage: a Geothermal system can be used for both, heating and cooling, eliminating the need for separate furnace- and air-conditioning systems. In addition, it can heat water as a byproduct.
In order for this system to work, a series of buried pipes are used to transfer the heat, during winter, from the ground into a building, converting it into warm air which is distributed through ducts. In contrast, in the summer, heat is transferred from the building into the ground which cools your home.

What we do:
Duffy's Electric & Geothermal LTD will completely install a Geothermal system by inserting loops into the ground using a directional drill and then hooking them up to a geothermal unit which distributes either the warm or cold air in your home. Our most commonly installed Geothermal System is is the Horizontal Closed Loop System, which is the least mess-accumulating way at a very affordable price.

How much do I save?
Geothermal Systems require much less electricity than other conventional electrical furnaces and air-conditioners, and thus greatly reduce your monthly electricity bill. Over time, these savings can accumulate into large amounts of money that stay in your pocket.
On average, a Geothermal System uses about 75% less energy than a conventional electrical furnace system.
No Mess!
While installing your Geothermal System, we aim to keep the mess on your yard to a minimum. All we need is a small hole 4x6' about 5 feet deep. Using our directional drill, we can install your system by drilling right underneath your yard.
There are four basic types of Geothermal subsystems. Which system is best suited for any particular house depends on the soil conditions, available land and on a few other factors. 1
The four different systems are:
  1. Horizontal Closed Loop System: the most cost-effective system, especially for new construction with adequate space. Most commonly installed using the directional drill. This minimizes land disturbance.
  2. Vertical Closed Loop System: used where land is not available. It also minimizes land disturbance. 
  3. Pond Closed Loop System: very handy and cost-effective when a deeper body of water is available
  4. Open Loop System: water is pumped up from the ground, circulates through system and is returned to the ground or a different body of water. Installation of this system is accompanied with many governmental regulations that aim to keep our water clean.
