Additional model ratings from NRCan

Natural Resources Canada reports the same brand, literal model and loop type in its public ground-source equipment list. These are separate source listings with their own verification references. They supplement missing EPA fields; they do not change the original EPA record or establish that different certification entries are interchangeable.

Cooling COP is dimensionless and is shown as reported. It is not labeled EER. Multiple rows retain different source verification references.
