Is there only one way to install an open loop system?
Yes. This set up is used less frequently, but may be more cost effective if ground water is plentiful. They are the simplest to install and have been used successfully for decades in areas where local laws permit. In this system, ground water from an aquifer is piped directly from the well to the building, where it transfers its heat to a heat pump. After it leaves the building, the water is pumped back into the same aquifer which is a second well or a drain tile.
