    Hot water radiator skunky Smell

    Hi All,

    Just moved into a new house that has hot water radiators. In one room (hardwood floors) there is a small gap around the pipe that leads up to the radiator from the basement.

    A very strong skunky smell has been coming up from this gap. Exterminators have come and said there is no way there is an animal (alive or dead) in there. I am at a loss, just curious if anyone has any suggestions on what this might be?

    Would not be coming from the radiator. The hydronic system should be sealed and under pressure.

    The water inside the radiators, and piping can have a distinct odor, more of a stagnant water type smell. There may be a small leak allowing the water smell to escape.

    Are you sure it's a "water" system?

    Maybe it's a steam system?

    If it's steam, leaks go unnoticed, without major water damage showing. If in a concealed space, it sprays hot mist, and could over time create mold.

    Could that be what your smelling?
