The IGSHPA standards committee produced a Standard Specification document for ground source heat pump systems for IGSHPA members. This specification is to be used as a guideline by engineers, designers, contractors, building owners and other interested parties who wish to specify geothermal/ground source heat pump systems. The specification can be downloaded from the link below.
Part of the design process should include minimum requirements, which are outlined in the design and installation standards. Select Standards from the Publications menu at the top of the page to review the ANSI/CSA/IGSHPA C448 bi-national design and installation standards.
The pipe that is buried in the ground is crucial to the system’s life expectancy. Recently, PPI (Plastics Pipe Institute) provided an update to the model specification for plastic piping materials for ground source applications, which can be downloaded from the link below.
