    Hi everyone, I'm considering buying a Hearthstone Equinox and will need to replace my 6" metal chimney.
    I would like install a masonry chimney on the outside of the house this time and I am interested in opinions
    between an 8"X8" V's 8"X12". Chimney Height will be 30 feet total. 20 feet above thimble.
    The Equinox has an 8" flue.

    Also if anyone has a Hearthstone Equinox I'd like to hear from you, not too much for reviews on this model.
    Thanks.

    There are a few Equinox owners on this forum. They will chime in at some point.

    So... did you move it your self or did you have someone else install the 700lbs of stone and cast iron?

    I would try out the Equinox on the 6" flue if possible. At 30', if this is an interior flue, it should draw like a bandit.

    My EQ uses the 8" round and my run is 20' straight up. Works like a charm. We are extremely happy with ours and would highly recommend it. We heat our 2900 sq ft solely with this stove. Good luck.

    for performance reasons, don't install it on the outside of the house unless you plan on doing a full insulated liner w/ it. If a masonry chimney is simply not plausible inside your house, go for a insulated class a manufactured inside... in the end it'll work better for you... and I'd go 8x12 (or actually it'll be 7x11 dimensional, probably.)

    BeGreen- I wish I could use my 6" metal chimney for this year and build the masonry next summer but if I had a fire I'm sure my insurance company would deny the claim??? Is there a way to do this legally?

    Summit- I've got an ugly stain on my new shingles do to coal ash washing off the chimney cap and running down the roof. My house has a big roof 10/12 pitch and it's in the front and looks like crap. I hoping with a masonry chimney on the side will be cleaner looking. But I'm wondering if the smaller 8X8 will draft better than the 8X12 because it will get hotter faster?

    why not use 8" round pipe? it will draw better that masonry, and be way cheaper to install

    Could the masonry chimney have an 8" ROUND clay tile flue? And insulate that with a very generous thickness of inexpensive perlite to keep it warmer?

    Is it legal to build a chimney out of concrete chimney block and instead of using clay tiles inside the block use an insulated 8" stainless liner? Might be cheaper than class A and look better than a pipe running along side a house.

    Would insulated 8" stainless be that much better than insulated 8" tile, other than warming more quickly?

    I was thinking stainless would be more durable, tiles tend to crack over time.

    It seems that would be the same as dropping an insulated 8" stainless liner down an existing unlined masonry chimney, so I don't see why it wouldn't be ok. But I don't write the laws.

    One could still insulate with that generous thickness of perlite, saving money on the insulation wrap.
