    All of the sudden...

    steam from chimney. I was plowing and looked up and STEAM!
    I have a brand spankin new Burnham Megasteam (oil), and everything runs great. No loss of water. I mean, everything runs great, but steam up chimney means less steam for the rads.

    Chimney Steam

    Probably normal, when cold and humid outside. Also, a megasteam has a cooler stack temp because it is more efficient than earlier boilers. The cooler stack temp predisposes the flue gas to quick condensation.

    If all else OK, no problem.
