AHRI noted that the second meeting centered around the Framework Document issued with DOE’s notice, which announced the initiation of the “second round” rulemaking on efficiency standards for residential boilers. DOE will review the current residential boiler efficiency standards and by July 15, 2014 will publish either a notice announcing that the standards do not need to be amended or a NOPR that includes proposed revised standards. At this meeting, DOE provided a preliminary schedule that indicated that if the July 2014 notice were a NOPR, then the final rule would be issued around July 2015 and would go into effect in July 2020. Much of the meeting was devoted to reviewing the list of items from the Framework Document on which DOE was seeking comments or information. In addition, DOE was asked whether any amended efficiency standard would consider both AFUE increases and prescriptive design requirements that improve efficiency. DOE was unable to provide a definitive answer, but will review the current federal legislation to determine the extent of its authority in amending the residential boiler efficiency standard. AHRI said it will continue to work with its Hydronics Institute Section to develop comments on the Framework Document that will be submitted by March 28, 2013.
