About Geothermal Heating and Cooling

There are two important parts to a geothermal system. These are the heat pump and the ground loop:

A heat pump is a device that moves heat from one location, which is the source (in the case of ground source heat pumps the earth is the source), to another location, your home or business. Heat pumps work exactly like air conditioning units, as both devices exploit the physical properties of an evaporating and condensing fluid known as a refrigerant. It is important to note that all ground source heat pumps we install utilize an environmentally responsible and safe refrigerant called EarthPure® HFC410A. A heat pump is mechanically very similar to an air conditioner with the exception of a reversing valve to allow the heat to flow in both directions, away from your home or business during the cooling season or into your home or business in the heating season.

The ground loop provides the means to extract thermal energy from the Earth. Typically bore holes are drilled, (the specific number depends on the heating load of the building), and a continuous loop of pipe is ran down to the bottom of the bore hole and then it completely reverses direction and returns to the surface. The pipes are then filled with water, and it is circulated between the ground and the heat pump. These ground loops provide the surface area required to transfer heat between the water in the buried pipes to the Earth.

The thermal energy stored within the earth is extracted by running a continuous pipe buried vertically in the ground. The pipe is filled with water which is circulated from the heat pump, typically located in the basement or mechanical room, through the ground, and back to the heat pump to complete the loop. We will only install closed-loop systems because they:

• Are the most environmentally responsible of all the geothermal systems available
• Do not displace aquifers by taking water out of the Earth
• Do not discharge used water into the environment
• Offer the lowest maintenance costs
• Have the longest life span of all the geothermal systems
• Are not affected by changing well-water temperatures

The beauty of geothermal systems is that they can be applied to both residential and commercial applications. Homes, schools, municipal, and commercial areas are great locations for a geothermal heating and cooling system. In addition, geothermal systems can be installed in new construction or existing environments.

Not only can your heat or cool your space, geothermal systems can provide forced hot water, forced hot air, radiant heating for floors and driveways, heat pools as well as integrate with solar heating systems.
