<p class=MsoNormal>Hello all,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Does anyone have any experience specifying high efficiency
steam boilers to meet the Advanced Building Core Performance Guide requirements?
Table 2.9.4 lists Steam Boilers at a minimum efficiency of 89% Et. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>From what I’ve been able to gather, high efficiency
steam boilers typically max out at 83% Ec/AFUE. Also, in speaking with local
manufacturer’s representatives, they have never seen a steam boiler
appliance achieve this level of efficiency. Is this a mistake? If not, does
anyone know of a product that can meet this efficiency level?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Any help would be appreciated.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks,<o:p></o:p></p>
