Any product not containing the letters “USP” will not be acceptable for this use, unless vendor documentation is produced to demonstrate equivalency.
Geothermal system – a sealed, watertight loop of pipe buried outside of a building foundation, which is intended to recirculate a liquid solution through a heat exchanger. This includes but is not limited to vertical loop, horizontal loop and body of water loop systems.
Geothermal system contractor – any individual who installs geothermal systems except a geothermal system excavator.
