The new CSA P.9-11 Combo System Testing…what you need to know
What is it?
Third party testing of combo space/water heating systems accredited by the Standards Council of Canada (CSA). The performance metric resulting from the testing is known as the Thermal Performance Factor (TPF).
Which types of systems are tested?
The scope of CSA P.9-11 states that it applies to:
- Forced-air or radiant packaged combo (heating and hot water combined) systems; and
- Combo designs/configurations with heat inputs up to and including 87.9 kW (300,000 Btu/h) for boiler-based systems, and a maximum input up to and including 73.2 kW (250,000 Btu/h) for water-heater-based systems, that are intended for field assembly.
How does this affect ENERGY STAR Homes?
By September 30, 2014, all ENERGY STAR Homes using Combo heating systems must use products tested and listed as meeting CSA P.9-11
How do I know if my current system has been tested?
All qualified systems will be listed on NRCan’s website.
