Does anyone know if there is such a thing as a universal damper for fireplace flu. My home is all brick, little or no insulation and built around 1912. There are no signs that there was ever a damper and from fireplace to top of chimney is about 30 ft and on top of a hill so the draw is huge. Ive installed glass doors but wonder if that is as effective as a flu damper. I thought about capping the chimney but don't want to climb to the roof to use the fireplace. Any thoughts?
Thanks Mark

    I shoulda thunk !

    Last night, there I was, reading a post about infiltration & thinking about the beautiful log (courtesy if Rita) fireplace roaring away keeping my office/kitchen/living room (and me) lovely & toasty @ 67*. But the heat was all at my back & right side!

    My left side & feet were Freeeeezing.

    In one hour, my cent-heat came on about 6-7 times ?

    What's going on? My bedroom & bathroom were at 62* ?

    The "beautiful" fireplace was sucking in air at gale-force 10 right through my frigid bedroom, dagnabit.

    Today was colder than then, but my heating has only come on no more than 2 times per hour.

    Here's what I did, & it cost about a buck.

    Hope this attachment works.

    Stay warm, fella's.

    Tankless in frigidland. (No fire tonight:)

    Did you notice that my clock goes backwards :(

    There are a number of quality chimney top dampers available, cable operated. Check this store out:


    or this site:


    But we opted to go this route:


    Little more expensive, but it will operate without power and beats having to find coal for our old coal inserts.

    Good Choices...

    ... I like the Lymance that we put on our chimney, for some reason the somewhat superior Lock-Top wouldn't work... I can't remember the reason, it was either that it wouldn't fit in the space we were given at the top, or the draft through the Lock-Top wasn't good enough for the folk at Bellfire. Yet, the Lymance dampers seem to get the job done, our rooms with fireplaces seem to handle the additional heat loss just fine.

    For fireplace choices you should also consider Bellfire if you like the old-fashioned "open" look. Bellfire makes the smallest pre-cast true Rumford fireplaces, with just 8" round flues. When my GC and I tried the basement unit, we couldn't even smell any smoke in the house. Then again, we had a lot more open walls back then.

    Hey hey

    what about my buck fifty sheet of 1/2" foil-backed styro :)

    It works perfectly. But then, this IS my house & nobody see's it except the 5,000 + visitors here :O)

    I do actually have a chimmely damper but it's broke & my slum er land lord won't fix a thing.

    My foil-backed styro looks like it's breathing when the wind blows/sucks :O)

    Bedtime for Bonzo.

    nice rack

    I put an airtight garage sale woodstove on the hearth after blocking in the fireplace with stone; then ran a new piece of metal "A" chimney straight out the roof. Warmest I ever was. I miss that place sometimes.
