We are looking into building soon and are very much interested in a geothermal heat pump. The property will also have to have well water, so we are wondering if there are any systems available that combine the well with the geothermal aspect?
Thanks

Any one for a pump and dump in his location in Fla?

Water quality is the biggest issue with a pump and dump. If your water is not of the right quality the system will build up scale and reduce the efficiency over time. Check the water quality in your area before drilling a well with enough capacity to handle your water needs and geo needs. My last project pump and dump was not an option due to the water quality and a closed loop system was used instead. All of this is relative to were you live and what demands you are putting on the system. Here in MA we are putting high heating demands on the systems and down south they are used more for cooling. That being said a pump and dump system provide the highest efficiency. This link shows the ground loop system we put in for the last project here in MA.

Here in CT we were required to separate wells for domestic water and geo by 50 ft. We have 2 geo wells and one water well, all 3 running to house in same trench. HTH

Don't do it , go closed loop ,do it right once and it will provide you free energy for life with little or no maintenance.

I all depends on where you live and the water quality in your area. Pump and Dump is pretty much a standard in South Jersey, I don't know of any closed loops in all of South Jersey.

South Jersey Residential is primarily open loop but closed is catching on. Most Schools are closed loop and our experience on barrier islands tends to go this way. Where water quality allows open is more efficient and usually more cost effective

I haven't seen this discussed, but scaling/deposits are a bigger problem in cooling areas than heating areas. Heating well water up causes the calcium to drop out.

Pros and cons to every system. As you shop for installers I think you will begin to see which type is percieved as the best fit for you by the pros.
Good Luck,
