<p class=MsoNormal>Hello All,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>First, thanks to those who contributed earlier posts on the
topic of modeling a “Loop to Loop” heat pump with a “Lake/Well
circulation loop. Those were of great help in developing my model thus far.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>At this point, I would like to try and incorporate a W-WHP
tied to my Lake/Well circ loop dedicated to DHW preheat. A separate circ
pump runs a loop from the W-WHP to a DHW preheat tank, reducing load on the DHW
boilers. The W-WHP is able to heat a limited flow rate of water to 110F in the
preheat tank, while the DHW tanks need the extra DHW boiler input to be
maintained 140F.<o:p></o:p></p>
<p class=MsoNormal>My problem has been the incompatibility between the DHW loop
and the Lake/Well loop. Then again, maybe preheat should be on a loop separate from
DHW.<o:p></o:p></p>
<p class=MsoNormal>Any ideas?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks,<o:p></o:p></p>
