Please help with fireplace question

Can someone please tell me that the difference is between these two chimneys from the outside only?

There are multiple differences, please refine your question.

One is brick and one is vinyl siding.

Or is it? I have seen dumbasses fasten vinyl siding to a masonry chimney, you have to take a good look at it to be sure. :thinking:

Statement based upon available information. Kind of hard to see what is under the siding from here!

And one has a clay liner while the other has an insulated metal pipe.

Exactly. The point is you can’t always assume it is a wood chase chimney. Looking at the age of the house and the chimney base, I would bet that there is a masonry chimney behind the vinyl siding. Further investigation is required on this one. Oh, You can put an insulated metal pipe up through a masonry chimney.

And one is taller than the other… :upside_down_face:

Oh, One is further down on the roofline, making it look taller than the other. :flushed:

is there a difference in life span? is one better than the other?

It depends what they are used for and how they are maintained.

The first image appears to be a masonry chimney with a clay flue.

The second image appears to be a “pre-fab” chimney with a metal flue.

The difference between the two is that the masonry chimney is built out of bricks and mortar.

The pre-fab chimney is likely a wood framed skeleton with a wood/osb sheathing and covered with vinyl siding.

My guess is they covered the brick, maybe was deteriorating, but it does appear that a metal flue was also installed, possibly added a gas log insert. I see the blue hose possibly has mortar deterioration above the roofline, and needs repointing. that is how I got my guess.

Morning, Tessie.
Hope this post finds you well.
As to your question, it would be my great pleasure.

1: The chimney on the/to the left, is a masonry chimney.
2: The chimney on the/to the right, is a chimney chase.

MASONRY: Masonry , ‘the art and craft’ of building, erecting, or/and fabricating, in stone, clay, brick, or concrete block.
CHIMNEY: A chimney is an architectural ventilation structure/feature, made of masonry, clay or metal that isolates hot toxic exhaust gases or smoke produced by a boiler, stove, fireplace…

CHIMNEY CHASE: A chimney chase, is a chimney by any other name, typically/usually/normally framed wood & siding.

Hope that helps.
