About to buy an antique home.
I have had a chimney inspector tell me this week that not only does the gas heating system share the flue with the living room fireplace but the wythe divider walls have either collapsed or were removed, essentially making it one big flue. 2 large flues supposedly go to the two fireplaces on the first floor and 3 smaller flues are for the 2nd floor.
Has anyone worked with a Thermocrete B2 cast-in-place liner system? What other Cast-in-place liner systems are recommended?
Will this system be able to create bigger flues for the two larger fireplaces on the first floor?
I am assuming this means I can create a flue for the gas heating system and not have to direct vent it through the walls.
I am having a hard time understanding/envisioning how they create a flue for a 2nd floor fireplace using the Cast-in-place system. Would they have to fill in that space from the 2nd floor down to the 1st floor with the lining material?
I'm leaning towards the Cast-In-Place over the Stainless Steel Liner since the flues are large and I don't want to hide the antique fireplaces.
If anyone could point me to a website that describes a cast-in-place system or has photos, greatly appreciated.
Thanks

JohnMass: Sorry for the late reply - just came accross your post, hopefully better late than never! Cast in place liners are a great option for restoration of antique chimneys. I know there are a couple of different products out I'm not sure the difference between any of them - if there is a difference at all. Guardian is one company that has developed a cast in place liner system they do have a website with pictures. www.guardianinc.com/
And I'm sure that if you do a google search or something with "cast in place liners" as the subject you'll probably be able to find much more information.
The flues are created using a custom "bladder" around which the casting material is poured. For fireplaces a smoke chamber will most likely be poured and carved with the casting material as well.
On another note: I know you said you wanted to avoid stainless steel liners, but they may be a good option (and in this case potentially more cost effective). The size of the original flue itself shouldn't determine the size of liner required for the fireplace - it is the firebox proportions that determine the size. And as for the heating system - you would just need a liner sized for the BTU output.
Sorry for the long post
