This article examines Silktech EcoAuro 1.0 and 2.0 heat pumps and their alleged failure to meet U.S. energy efficiency standards. It highlights concerns over inflated performance ratings, incorrect use of efficiency metrics like EER and COP instead of SEER2/HSPF2, and misclassification under federal guidelines. Reported calculation errors further question the accuracy of published data and the units’ compliance with legal requirements for the U.S. market.
