    Is there currently a problem?

    The question has a number of answers, sort of along the lines of proving a negative.

    If the returns are clogged, you would not get water back to the boiler causing a make-up scenario and potential flooding, as one condition.

    Is there an operating condition which causes you to suspect the returns?

    Brad,
    I am just looking to make sure the system is operating the way it should. I have no problems. Would the piping tend to get warm?

    Warm return piping

    Sy,

    Yes the return piping should be warm if not hot at least by the end of each cycle. Certainly less than 212F, but warm or hot to the touch.

    That is normal and expected.

    If the return gets warm or hot ahead of the mains when the boiler is firing, that could indicate a loss of seal at the Hartford Loop, with live steam backing into the return. Of course, if that were happening, you would not be thinking that the system had no problems. You would have banging, surging and a host of other issues, spitting vents, cats mating with dogs, absolute pandemonium. :)
