A July 23 final rule from the U.S. Federal Trade Commission (FTC) revises EnergyGuide labels for residential water heaters—but the Air-Conditioning, Heating, and Refrigeration Institute wants the Nov. 15, 2013, effective date delayed.
AHRI sent a letter to the Federal Trade Commission (FTC) asking the FTC to defer the effective date, noting that the major changes will result from a revised “universal efficiency descriptor” test procedure that is being developed by the Department of Energy.
AHRI also found an error in the EnergyGuide labeling rules, regarding capacity information for residential gas instantaneous water heaters. The association addressed the error in its letter to the FTC.
AHRI also addressed a discrepancy in the final rule, which can result in models using the same type of fuel and with the same efficiency rating to end up with different estimated annual energy costs.
