Pond Boss Forums GENERAL QUESTIONS Property Projects & Construction Geothermal pond loop and aeration?

I am not sure there is still any interest in this thread but maybe somebody will find this useful. In fall of 2013 we started constuction on our new house and quickly learned the garage floor was 9 feet above grade! We needed dirt and lots of it for fill. I checked with my excavator and I could dig a pond and use my own dirt for roughly half the cost of buying and hauling it in. Soooo I had the push I needed to look at fulfilling my boyhood dream of owning my own pond. As the pond was a real posibility, I started thinking about geothermal heating and cooling. As it turned out, for an additional 10K I could up size my planned well, install an ultra efficient variable speed constant volume well pump and install a geothermal pump and dump heating and cooling unit (backup is natural gas furnace). For an extra 200 dollars I had the plumber put in a bypass so I can directly supply my 1/4 acre pond with up to 35 GPM of water from the well in times of drought and still have plenty of capacity for the house needs. Whenever I am heating or cooling the house I am also pumping water into the pond but I really don't see a temperature or level change. Here is one side benefit, until 2016 you can realize a 30% tax credit on costs associated with installing geothermal!
