: in reply to all the questions you asked...no the top of the boiler is not sooted...we can not see up the chimmney...yes we have a pump, the coupling is fine and is turning once boiler is warmed up...2 pipes out of the rad's but no expansion tank in any closet or room upstairs with a overflow pipe running out of the house...have not checked temp. gauge, not sure where it is at. Photo's would surely help...sorry for my ignorance...Micki.....i think you need to check the impeller in the circulator,or look for a closed valve in the supply or return line.
