To answer your questions I would need to know how far from the home your pond is. With a pond loop the real savings is in the trenching.My pond sits 100ft from the house so the digging was not so expensive. For my home with out the pond loop I would have needed 400ft of trench 6ft deep(ouch!)A second advantage of the pond loop is better transference of heat and cold than through a earth buried ground loop.(A pond is a better conduit) If I remember correctly you would need 1/2ac pond at 8ft min for a 4 ton unit.(in southern iowa) In Georgia I would guess you could get away with less dept but I would not recommend it. Does it save money?.. Yes. Several ways, The utilities company may cut you a break on your electric if a majority of your home is running on electric, my rates are cheeper by 50% for 6 months of the year. second- Most systems are tied into your water heater or replace the water heater completly. heat drawn from the home in the summer will heat your tank,hot tub or whatever.I bought a closed looped system based on more of a northern location (freezing)and I belive less maintanace. There are a lot of smart folks here who can tell you all you need to know about open systems. In Georgia heat pumps are used quite a bit. A geo system is very simular, a heat pump extracts the heat from the air at outside temps(dont work too well up here) the geo does the same thing except through the earth or water where the temps are 50 to 70 degrees at all times plus the unit is located in your home- less outdoor wear and tear . Remember A geo does not creat heat or cold it simply moves it, and thats where the true savings over the long term are. Hope this helps you out.
