    I bought one of those magnetic chimney thermometers before I realized they were only for single wall pipe. If the pipe materials are the same and the space between the pipes is consistent, I thought there might be a rule-of-thumb conversion to use to be able to still use this thermometer (i.e., multiply reading by 2.5 to get pipe temperature, or something like that).

    Has anyone seen anything like that?

    If not, what do you use with double wall pipe?

    Thanks in advance for any information you might provide.

    Thanks, jeff_t. I was just hoping maybe I could use what I already bought! If not, that seems like a great idea.

    Get a probe, and use the magnetic on top of the stove.

    My advice as well . . . this way you can measure the temp of both the flue and the stove.

    There is very little correlation to the surface temp of an insulated double walled pipe to the actual temp inside.

    The rule-of-thumb conversion is:

    "It's a hell of a lot hotter inside the flue than the mag thermo measures on the surface." ;lol

    Thanks everyone. It sounds like we need a probe!
