AHRI Standard for Commercial Water Heating

The Air Conditioning, Heating, and Refrigeration Institute has initiated AHRI Standard 1300P/1301P entitled “2011 Standard for Performance Rating of Commercial Heat Pump Water Heaters.” A Working Group consisting of 15 members from the water heater and heat pump industry was formed to create a definition and performance standard that will provide an accurate portrayal of the efficiencies of the various heat pump water heater technologies that exist today.

The proposed final draft of the Standard was presented to the Working Group vote but failed to meet the approval of the membership due to unexpected changes to the document relating to testing conditions. The results of the letter ballot and comments of the voting members have been forwarded to the Working Group Chair, Mr. Titu Doctor. Further work sessions have yet to be scheduled.
