IGSHPA Design and Installation Standards
IGSHPA Standards Committee Mission:
The objective of this committee is to write industry standards that:
- help protect the environment and our natural resources,
- help to ensure the thermal performance of the critical components of the system, and
- are written in such a manner as to allow for new innovations and ideas that might improve the first two objectives.
IGSHPA has led the way in providing a complete set of standards for GHP systems. This 2017 updated edition incorporates all the changes recommended by the IGSHPA Standards Committee since 1994, and is a must for everyone involved in the GHP industry. This manual covers design and installation standards for closed-loop ground heat exchangers, pipe placement and backfilling, indoor piping and circulation systems, geothermal heat pumps, and site planning, records, and restoration.
