ECONAR^® Energy Systems - Commercial Case Study
Woodlands Bank - Onamia, MN

Woodlands Bank in Onamia, MN stays nice and warm all though the winter due to their parking lot. Beneath their parking lot lies a vertical loop field of many small wells. These loops circulate a water solution which extracts heat from the earth. The heat is then carried into the GeoSource heat pumps in the bank. Once the heat energy reaches the heat exchangers of the heat pumps, it is absorbed by a refrigerant, which is compressed and rises in temperature to about 160°. The heat is then absorbed by the air heat exchangers, from where blowers circulates it to each room without taking any humidity out of the air like conventional furnaces. During the summer, the bank simply reverses the process, by removing the heat, which produces a cool, dehumidified interior.

Geo$ense

When deciding on the heating and cooling system for the new building, many factors were taken into consideration. Along with comfort, reliability, and ease of use, the projected annual operating cost of the GeoSource heat pumps made the decision easy for the bank.
