Product Information: United States Ground Water Temperature
Map
The United States Ground Water Temperature Map is a tool
designed for residential use. It provides information about the
average ground water temperature in different regions of the United
States. The map allows users to correlate their location with the
legend to determine the average ground water temperature in their
area.
Please note that the indicated temperature zones are general and
may vary due to local variations and seasonal changes.
The product model for non-condensing use is RE180i/e, with a BTU
rating of 180,000.
