radiators that just will not get hot

mike d_2

i have ahydro boiler and it has about 6 radiators the first 3 get hot but the last three do not I talked to a rep he told me that I could pipe them in a loop 3/4 foster pex in to one out to the next i had problems so he told me to put a bigger pump on I did that it did not work so I made sure that i did not tie in to the first floor loop i did not but i can not get to one half of the system could i split the system to two zones 3 rads on one loop and 3 rads on the othere

> WATER HYDRONIC



how big are the radiators, how big is your boiler, btu's wise. did you bleed the air out of the system,is there air in the radiators,are there valves in the rads,and are they open,when the pump starts to run are you getting cold water on the return, is it a single or split loop system ??


these are some things that should start you in the right direction

first to feed...

how about this simple rule when dealing with multiple radiators in a zone... (first to feed,last to return)
