Omar,<br><br>I believe that despite of the pump capacity that you put in, the software uses a flow that the building needs in order to provide enough heating to the building load. As a result, the PV-A is giving is different numbers that what you have manually put in. I am not 100% sure if my answer is right, therefore if someone else can also share something, that would be great.<br>

<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">Dear all,</span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;"> </span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">I just noticed the following while examining
my PV-A Report:</span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;"> </span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">I have 2 boilers connected to the same hot
water loop, each having a pump attached to it. </span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">Attached to the primary HW loop is a
Secondary hot water loop with its secondary pump attached to it. The screenshot
“Heating Strategy.jpg” explains this.</span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;"> </span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">Now, I assigned a loop flow of 200gpm for each
boiler pumps, and 200gpm for the secondary HW pump. The loop recirculation
flows for the Primary AND secondary HW loops is 200gpm also for each.</span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;"> </span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">The issue is that, in my PV-A Report, I
see:</span></font></p>
<p class="MsoNormal" style="margin-left: 36pt;"><font color="navy" face="Wingdings" size="2"><span style="font-size: 10pt; font-family: Wingdings; color: navy;">Ø<font face="Times New Roman" size="1"><span style="font-family: "Times New Roman"; font-style: normal; font-variant: normal; font-weight: normal; font-size: 7pt; line-height: normal; font-size-adjust: none; font-stretch: normal;">
</span></font></span></font><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">200gpm for the 3 pumps
(as expected), BUT</span></font></p>

<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;"> </span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">Does anyone have an idea of why the last 2
numbers changed, even though I manually set these to 200gpm in the program?</span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;"> </span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">The issue is that I need to simply stuff
for the LEED Reviewer, because they’re being really annoying in terms of
auditing every single decimal point!</span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;"> </span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">Many thanks for your help.</span></font></p>
