Geothermal is ground source heat pumps that are electronically powered systems that tap the stored energy from the earth. These systems use the earth’s relatively constant temperature to provide heating, cooling, and hot water for homes and commercial property.
Wow what a concept on how to heat and cool, take what is naturally replenished and using it to keep your family comfortable in your dwelling, or your employees comfortable in your work environment, all while minimizing your carbon foot print, reducing your monthly energy costs and being the most efficient property around!
How It All Works
Typically, geothermal systems have what is called a Loop Field that creates a sealed system. This is a series of plastic pipes that is made of high-density polyethylene plastic, known as HDPE (high density poly ethylene) in the industry. The HDPE system is typically heat fused together using a process that is called heat fusion that bonds the HDPE piping together, welding the materials together with no other materials but the HDPE plastic pex piping. From there, there is a series of loops that feed the geothermal system energy from the earth. The loops are typically sized for the structure it is to maintain and the size of the geothermal system.
The system operates by using a refrigerant and a compressor to produce heating or cooling with the loop field being its energy source. Even though the system still uses electricity, it gains most of its energy from the earth’s energy (temperature). This is where most of the efficiency is created. On a sealed system there is a pump system that moves a fluid (this fluid is water-based) through the loop field into the geothermal system, from they’re the water-based system, water or antifreeze solution is circulated through plastic pipes buried beneath the earth's surface. During the winter, the fluid collects heat from the earth and carries it through the system and into the building. During the summer, the system reverses itself to cool the building by pulling heat from the building, carrying it through the system and placing it in the ground.
This process creates FREE hot water in the summer and delivers substantial hot water savings in the winter!
Geothermal systems can be installed in many different applications that can fit any type of heating application from very typical forced air, in floor heating, hot water heating, chilling, snow melting, pool and spa heating and many other applications. If it needs heating or cooling geothermal can get the job done!
For every 1 unit of energy it consumes it produces 4 units of heating or cooling energy.
Geothermal Systems can save you up to 50% off your current heating and cooling bill.
Typical payback on new homes ranges from 2 to 8 years.
On replacement systems it can be as little as 2 years when converting from propane or fuel oil OR 7 years for natural gas systems
Geothermal reduces the green house gas emissions and reduces the need of fossil fuels (natural, propane and oil fuels).
On typical new construction homes, the pay back usually runs 8 years or less, the more geothermal that is installed, typically gives a shorter return on investment!
There will be a time in our lives that geothermal will be the typical system to install instead of the most efficient system available!
