ARLINGTON, Va. — The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) is pleased by the results of verification testing of appliances and tankless and storage water heaters released by the U.S. Department of Energy (DOE) under the Energy Star® program. The released results show that all tests of the claimed efficiency levels for storage and tankless water heaters turned up not a single result that would require further action.

“The results of these tests support our belief that our certification participants’ products are being properly rated and should not be the focus of enhanced federal scrutiny,” said AHRI president and CEO Stephen Yurek. “The water heater tests are an excellent indication that AHRI’s private-sector certification program should be relied upon by DOE to verify compliance with federal energy-efficiency standards.”

Of the products tested, only tankless water heaters and storage water heaters had perfect results, while no other category had less than 14 percent of the products requiring further action.
