Vertical closed-loop ground heat exchangers that are intended for connection to a direct expansion ground source heat pump are covered under ANSI/CSA/IGSHPA C448.10.

1.2  Thermal energy storage systems

This Standard also applies to the vertical closed-loop ground heat exchanger portion of a thermal energy storage system.

1.3  Minimum requirements

This Standard covers the minimum requirements for site survey, material selections, installation, testing and verification, documentation, commissioning, and decommissioning.

1.4  Units

The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.

1.5  Terminology
