    The commonwealth building in my hometown of Portland Or was the first building to have geothermal, anybody know if it is still in operation? It was installed in 1944 and and the building was completed in 1946 if i remember correctly.

    Changed 1st residential geo!

    My company changed what is believed to be the 1st. residential geothermal system installed. We were asked to leave a portion of it in its original installed space.
    Project: Dr. Carl Neilsen (Ohio State University Physics Professor)
    Location: Columbus, Ohio (Sawmill Road)
    Estimated Original Install: 1950's.
    Replacement: (2006) Open Loop FHP Geothermal. Later converted to a vertical loop.
    FYI: Property is still owned by the family and system is operating properly.
    Contact me for any supporting information pertaining to this project.

    Correction: 1948 Install date.

    I posted an incorrect date of orginal installation. This project was originally installed in 1948. YES, this is NOT a typo.
    We changed this system out as described in previous thread.

    I remember when I was a little kid, I went to some Indian ruins in the Painted Desert in Arizona with my dad. They had a hole in one of the rooms that had cool air coming out of it to this day! The roof and tops of the walls were no longer in tact but the a/c was still pumping. It connected to some underground caverns and I guess they may have just stumbled across a hole in the ground that had cool air coming out and built around it. But that has to be one of the first geothermal systems.

    Just goes to show that there really is nothing new under the Sun.
