Inquiry
The efficiency of a ground-source heat pumps varies depending on the ground or water temperature. How should the efficiency (EER) of a ground-source heat pump be determined - based on the mean temperature below frost line, bin-weather analysis, or some other method?
Ruling
Credit for EA 6 must be based on the rated efficiency (EER or COP ) as determined using the standard test conditions set by the Air Conditioning and Refrigeration Institute.
