sounds like an 8 inch appliance necked down to a 6 inch thimble if he has a lined flue should not need to slip line , but should stay with a 6 inch flue'd appliance which should be ok in a ,2K sq ft house, a 2 to 2.5 CF sized unit would be what I would shop for, as long as the home holds heat reasonably well big enough to hold overnight , small enough to keep the paint from peeling in the stove room.
 
Hi fever- OK sounds like a 7 x 7 tiled chimney about 16 feet and trying to heat around 1700sqft. Running an eight inch stove into that configuration prob not the best thing to do, downsizing the stove's outlet. The best course of action would be a 6 inch stove into that flue. Prob would run fine, relining would be a bear and shouldn't be necessary if chimney sweep says chimney in good shape. A good size steel stove seems to be in order. Something like a Quadrafire 4300, Osburn 1800, PE 27, Enviro 1700 Kodiak, the list of many great stoves goes on. You are going to need some good dry seasoned wood though or it will all be for nothing. Seasoned wood is the key, seems to be the theme here too.......
 
So how do I run a 6in. stove.....just use a reducer? The pipe going into the chimney is 8in. Yeah, definitely need to stay out in front of the wood situation from now on.
 
I might see how it does this winter without the smaller liner and see how it does. Next season I may try to install the smaller liner.

How much do you think I could get for an old Solar Key?
 
If it was me however I would run a 5.5" liner down that chimney and on top I would extend it another 2 feet.

why would you run a 5.5" liner for a 6" stove? and the height should be fine as long as it is high enough with regards to the roof

that's weird, why would there be an 8 inch thimble for a 7 inch flue?

anyway, the 30 would do just fine with a 16 ft chimney like Mellow said that's what we did our R & D plus epa testing connected to. 16 to 18 ft flue @ 7 inches is just dandy for any of our stoves i see no need to reline to a 5.5 (which would work) the existing liner which according to the sweep is fine adding the liner is an expense which should not be necessary.

I know you are against liners in a "good" chimney, but that is what would fit down his chimney. I suggested the extra height for added draft. Thanks.

I am not necessarily against liners in a good chimney i am against the wrong sized liner in a good chimney just because that is all you can fit in there easily I just don't see why you would go with an undersized liner Do it right with the right liner if you are going to do it. But it will probably work just fine in the 7 by 7 as long as it is in good shape with proper clearances. And there should be no need at all to add to the height at 16'

I was wondering too why an 8 inch thimble (if indeed it is, I hope it wasn't reduced down there...) would be on a 7 x 7 liner, however all quality stoves should run fine on that chimney. I see no reason to reline it at first, if it doesn't work well, then maybe relining might help. Initially at least, I'd try as is, get as good a quality a stove as one can afford, get the wood seasoned and stay warm.
 
I just measured..... the thimble is indeed 6 in. The output on the stove is 8 in.

Ok then, you're all set. Get a good new stove and hook her up.
 
yeah, i agree with stovelark , with one caveat,

get the flue cleaned out before mounting the new unit , NFPA211 requires a level 2 inspection before mounting a new stove to an existing flue anyway (which is essentially what your sweep has been doing for the most part i imagine. )
 
Guys, I had the sweep over today. Was checking over his work after he left and noticed this crack. Apparently he missed it. How difficult is it to replace a thimble? It is probably fused in there pretty good. Would I have to chip it out and put in a new one?

they can be a pain you should have your pipe run all the way through that thimble anyway and if you do that and you have proper clearance for the thimble it should be ok.
