CGC Certification of Geothermal Systems, a Guarantee of Quality

Individuals are accredited after successfully completing the training, with a passing mark on the examination, and applying for accreditation. There are three different types of accreditation: vertical loop installers, systems installers and residential or commercial designers. Accreditation is valid for two years and requires the following:

• A passing mark on the relevant CGC examination
• Credit references if and where appropriate
• Proof of adequate insurance and liability coverage if and where appropriate
• Satisfactory work on five previous geoexchange systems
• Assent to the CGC Code of Conduct.

 
A system is certified once CGC has approved an application for certification. Certification means that the system has been designed by an accredited designer and installed by an accredited installer, and that any borehole work has involved an accredited vertical loop installer.

For a system to be certified, it must abide by all guidelines within CSA Standard C-448-02, use ISO/CSA-approved equipment, and follow best practices such as delivering an "as-is" book to the project owner, clearly labelling all piping and valves, being verified and inspected as necessary to ensure the system is in compliance with all provincial regulations, etc.).
