Hello

I am registered with the IGSHPA - International Ground Source Heat Pump Association.  I am certified to fuse the geothermal pipe together, and I have worked with many heating and cooling contractors in setting up a geothermal system for commercial and residential customers. 

Closed-Loop Vertical for Geothermal Systems
This type of loop configuration is ideal where yard space is insufficient to permit horizontal buildings with large heating and cooling loads. Vertical holes are bored into the ground 150 to 450 feet deep.  Each hole contains a single loop of pipe with a U-bend at the bottom. After the pipe is inserted, the hole is back-filled or grouted. Each vertical pipe is then connected to a horizontal pipe, which is also concealed underground. The horizontal pipe then carries fluid in a closed system to and from the Geo-Exchange system. During the winter, water or an antifreeze solution is circulated through buried pipe, collecting heat from the earth and transporting it into the building. During the summer, the system cools the building by reversing itself, collecting heat from the building and transporting it back into the earth. Vertical loops are generally more expensive to install at first, but in the long run it is much more efficient and inexpensive to run than a regular furnace. On average you can run a Geo-Exchange system for a lot less than a regular furnace or air conditioner. It will cut down the cost of heating and cooling your house.  Vertical loops require less piping than horizontal loops, because the earth deeper down is alternating cooler in the summer and warmer in the winter.

As an additional benefit, Geo-Exchange systems can provide inexpensive hot water, either to supplement or replace entirely the output of a conventional, domestic water heater. For more information to compare your heating and cooling you have now and the pricing of a Geo-Exchange, please feel free to contact Cesal Well Drilling. I am also certified to fuse the pipe for the geothermal.

How long will the loop last?
Closed-loop systems should only be installed using the appropriate high-density polyethylene pipe.  Properly installed, these pipes will last over 50 years.  They are inert to chemicals normally found in the soil and have good heat conduction properties.  PVC pipe should never be used.

If the loop falls below freezing, will it hurt the system?
No.  The Antifreeze solution used in loops that operate at low temperatures will keep it from freezing.

Can a geothermal heat pump also heat water for my home?
Yes.  Some types of geothermal heat pumps can save you up to 50 percent on your water heating bill by pre-heating tank water.

What does a system like this cost?
To get an accurate comparison of costs you need to consider the following:

• Payback, or how long it takes to recover the difference in costs between the two systems using energy savings.  Payback for most geothermal systems runs three To five years.
• Total operating savings from heating, cooling, and domestic hot water must be combined to get an accurate picture of total energy savings.
• Maintenance costs and system reliability
• System lifespan 

Here is an example of the savings of a geothermal system, and an example of a vertical loop installation.  We do not do horizontal loop installation.  If you have any questions, please feel free to contact us.  We will try to answer your questions.
