IGSHPA is taking pre-orders for the 2025 edition of the CSA/ANSI/IGSHPA C448 Design and Installation Standard for GSHPs
The 2025 edition of the C448 standard will be available the beginning of June! The new edition has many new updates and is the basis for all new IGSHPA training. Following are some of the updates to the nearly 250 page standard:
- New section on District Energy Systems
- New section on Energy Foundations / Energy Piles
- New annex on Waste Water Energy Transfer Systems
- New PE-RT piping material added
- New glycerin-based antifreeze and detoxified ethylene glycol added as acceptable heat transfer fluids
- Consolidation of clauses that appear in more than one section (moved to the General section) for ease of use and clarity
- Removal of PVC as an acceptable piping material for inside piping
- Validation of references used in clauses throughout the standard
- Review of IGSHPA Standards Committee recommendations for changes to the standard that will allow the 2017 IGSHPA standard to be sunset when 2025 C448 is published
The new standard will be available to current IGSHPA members at a discounted price of US$175 for the licensed PDF version of the standard. Non-member pricing for licensed PDF or for the paper copy (purchased through CSA) is CDN$250, another benefit of being an IGSHPA member!
