If you have access to a Pond you are very fortunate. These geothermal loops are one of the most simple to design and are relatively the cheapest to install. Water, in most all regions, remains relatively the best energy exchanger and works well because the very high conductivity of water compensates for the cool or warm temperature. This design and application is considered the most efficient.

Pond Loop

The Pond (hybrid) loop is a key part of the hybrid geothermal system and it must be properly designed and installed. The plans to the loop ground field are easy to understand and applying this design is quite simple. Careful consideration is necessary to ensure that there is sufficient capacity available for the geothermal heat pump to operate properly. Design consideration has a few requirements to using a Pond . For clean lakes and ponds a simple pump and dump system can be used. Returning the water back into the lake or pond. Do you have a lake or pond access?

The pond loop or heat transfer coil should be placed at depths of  8 ft and take into consideration of water table dropping. This will get well below possible freezing. Coils of pipe are usually connected together on skids and pulled into the water. A Heat Transfer Coil is usually designed on a skid or frame and is also pulled out into the water. Then a trench is dug leading to the building then burying the exposed pipe.

There are new designs of Geothermal Water Heat Exchanger coils and when  combined together with the new designed heat pumps makes one of the best energy saving Heating and Air Conditioning systems available. These smaller designed coils can handle multiple spilt systems with just one coil.

This technology relies primarily on the earth’s natural hybrid thermal energy, a renewable resource, to heat or cool a home or commercial building. The pond loop system combined with a ground heat pump (GHP) provides a simple economical energy solution.

Homeowners and businesses who use Ground Source Heat Pumps (GSHP) systems give them superior ratings because of their ability to deliver comfortably warm air, even on the coldest winter days, and because of their extraordinarily low operating costs. As an additional benefit, Ground Heat Pump (GHP) systems can provide inexpensive hot water, either to supplement or replace entirely the output of a conventional, domestic water heater.

Geothermal Loops can be install in Rivers - Ponds - Lakes

  Clean lakes and ponds can use a simple pump and dump.

Pond loop may be the best solution available. Pond loops use coils, in most cases is a slinky design, made of polyethylene piping or modern heat exchanger coils submerged into a pond or lake. They have the benefit of low installation costs in addition to the benefits of a closed loop circuit. Also, pond loops typically have more mild operating temperatures. Pond loops are also in widespread use in the commercial market due to the compact size and low initial cost compared to installation of horizontal and vertical loops.

New water systems are now available. Lake and pond all-in-one geothermal water pump and dumps systems. Excellent for farmhouses, homes, trailers, greenhouses, indoor gardens, and more.
