CRN Registration for Boilers and Hot Water Generators in Canada

Boilers and hot water generators are the most strictly regulated pressure equipment in Canada. Every province requires CRN registration for boiler designs before installation. Kopfkino provides CRN registration for steam boilers (ASME Section I), heating boilers (ASME Section IV), and waste heat recovery boilers.

Applicable Codes for Boiler CRN

• ASME Section I — Power Boilers: steam boilers above 15 psig steam pressure
• ASME Section IV — Heating Boilers: low-pressure steam heating and hot water boilers
• Heat Recovery Steam Generators (HRSGs) — multi-circuit boilers requiring detailed code selection

Provincial Boiler Registration Requirements

All provinces require CRN registration for boilers. Ontario (TSSA) and Alberta (ABSA) have the most detailed requirements. Quebec (RBQ) has specific requirements for heating boilers in residential and commercial buildings.

Frequently Asked Questions

Does a commercial hot water heater need CRN?

Water heaters above threshold pressure and volume require CRN. Many commercial water heaters from major manufacturers already carry Canadian CRNs. Confirm before installation.
