Bought a house and want a better set up for heating, next winter season is the goal. Slowly learning about chimneys and my setup. Split level. Thermostat is on the third floor. Middle floor drops a decent amount and first floor on the concrete slab is around 45-48 at all times. Insulation/doors/windows will be addressed when the time comes, built in 1967. Fire place is on the first floor slab. Pictures attached with what I’m working with. Plan is to cut the fireplace opening to floor level and fit a blaze king 40. If I end up keeping the fireplace the same id consider the princess as an insert. Less time throwing wood in is my goal if anyone is curious of my choice for freestanding and heat output. My questions, besides opening it all up and fitting it inside. Making sure the 8inch liner fits all the way up. Any other issues or things I should consider that you all see and know that I don’t?

Along with removing both side flues on top of the chimney. Instead of just capping them. Make it flat like the rest. Would I need to add a barrier/plate inside the chimney to prevent drafts and cold air from coming down beside the liner?

BK doesn’t recommend stoves in fireplaces as it affects how the tstat operates. How tall is the chimney? Can you fit an 8” insulated liner?

There is this option for an insert if it fits.
 
I agree with ebs-p. BK won't operate well it it is even a little tight.
Also, making the fireplace larger to accommodate a stove may affect its mechanical integrity?


Put an insert in, that is why they exist.
Also, go with one with a 6" flue. That doesn't limit your choices in the future.

Finally, why not line the flue, make a thimble on the middle floor where you spend most of the time? Install a free stander there and close the fireplace on the slab.
