I have a WLHP Tower Pump sized at 540 gpm and the boiler pumps are 184 gpm as per the system design. I am getting an error which says that the boiler pumps can’t handle the full flow of the condenser loop but I didn’t think they had to. This is also causing an insufficient heating problem. My guess is that I have made an error in the way I have attached the boiler pumps to the loop but I don’t know how to fix it. I’d appreciate any suggestions about how to correct this. <o:p></o:p></p><p class=MsoNormal>Thanks in advance,<o:p></o:p></p><p class=MsoNormal>Gerry Hazel<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Gerard Hazel <o:p></o:p></p><p class=MsoNormal>M&E Engineers, Inc.<o:p></o:p></p><p class=MsoNormal>908-526-5700 x14<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
