Freestanding wood stove in zero clearance design?

Is it possible or practical enough to put in a large freestanding stove where my zero clearance wood stove is now? I have a feeling that this is a very expensive project if it is even possible at all.

It's possible with some planning. There are a lot of stoves on the market that are approved for an alcove, and have pretty generous clearances.

Is your fireplace cantilevered from the house? If it's not, then it wouldn't be an alcove install anyway, just remove all the framing around the fireplace. The chimney will need to be replaced with a class A system.
If you pay to have the work done, expect at least $6,000. Of course this would depend on the height of the chimney.

I'd suggest double checking this one - my understanding is that the definition of "alcove" install has more to do with the ceiling clearance above the stove (and possibly the side clearances) than how the floor is supported.

I didn't say anything about the way the floor was supported.
I am saying: If it's a cantilevered fireplace, then it would be considered an alcove after the fireplace is removed, unless the stove sits in front of the bump out.
If it's not cantilevered, then once the framing is removed, it's not an alcove. Above the stove would be the original ceiling, the same as the rest of the house. Therefore not an alcove. The fireplace and all the framing for the fireplace would be removed.

If the wood stove and zero clearance fireplace are removed I am guessing it would be considered an alcove. I have 9' ceilings in the room that i would be installing the stove and the house is 5years old. I am guessing that i do not have a class A chimney either.

What would i get w/ a class A chimney vs what I already have?

If it helps the other problem with that chimney is that there is no way to support it safely. Most likely it is air cooled double wall system. When you pull the drywall off you will see on top of the fireplace air holes that allow the cooling air up the chimney. There is no support box made for this system and it is not approved any way.

There has been alot of chatter this year about folks wanting to convert something ZC to something woodburning airtight. Can someone explain to me how Heatilator certified their Constitution high efficiency fireplace (that is basically same as an insert) that uses the exact same air cooled chimney as their ZC's do. I was recently in a showroom where you could walk in behind the mock ups. The Constitution and a ZC right beside each other with same SL300 chimney. Just curious

I had an insulated liner installed when putting in my winterport but If i want to go any bigger what kind of chimney and piping will i need?
