What is a closed loop system?

A closed loop system uses a continuous loop of buried polyethylene pipe. The pipe is connected to the indoor heat pump to form a sealed, underground loop through which an environmentally friendly antifreeze and water solution is circulated. A closed loop system constantly re-circulates its heat transferring solution in a pressurized pipe.
