is it installed so flow is correct??? if there are flow checks - trying to circ water against them makes the circ cranky. is the circ correctly sized?? too big or too small?? are all valves open? is this problem coincidental with the circ change a few months ago??

    running out of ideas..

    Im new to the heating by hot water and have tried what little we know. I have a boiler that is producing hot water...the pipes are hot, heat is slowly coming from the pipes...but can't get the temp over 61 degrees even when cranking it up to 80 for a couple hours. I've tried bleeding at every spot...and got a lot of air out. The pressure is good. We aren't getting the rushing water sound that we were getting for the past few months, but not sure if that is good or bad. Don't know what else to try...any suggestions?

    No sound of rushing water in the pipes might mean that the pump is not working.

    It is most likely air bound. The noise in the pipes was air.

    it may work....

    just that there is air in the piping. Are the pipes warm/hot 20' from the boiler?

    no/low heat

    As far as the pump goes, I always ALWAYS go by the idea," just because its new, doesn't mean its good." I will guess here that the pump is a compact circulator. Use a stethescope or screwdriver method to determine if it is humming or actually spining. In the threads posted so far I do not see the boiler pressure indicated. Do not go by the boiler gauge but rather a gauge made to screw onto a boiler drain. Its a standard tool I keep on the truck to make sure there is ample pressure in the system. keep us posted

    pump working?

    the pump can be working(buzzing, humming) but still not being actually pumping water. air up higher in the line can keep it from moving water.

    sounds like the pump - if not a physical blockage... just my opinion

    What temperature is the aquastat set at?
  • Is the...

    Pump motor excessively hot? If you don't like keeping your hand on it very long chances are it's airbound. Motor should feel warm but not hot.
