What size is the flue what size is the outlet on the furnace what is the btu output and efficiency of the furnace? If it is a low efficiency boiler and the outlet size matches the liner size closely it probably wont make much difference. But if that was the case your furnace guy would not have recommended a liner
Yeah its a pretty safe bet you need a liner. I cant say what size without the height of the chimney but it is probably 6"
More consistent draft. Less condensation which will eventually destry your chimney. If your furnace guy is having a hard time setting the draft it is probably pretty bad. But i am not there to see it. For an oil furnace we usually just pour insulation around it. It helps stabilize the draft quicker but you don't need the insulation for safety reasons like you do for wood or coal.
Old bump, but some new info:
So, I was measuring for the liner and there seems to be some strange bends in my flue? I think getting a 6" down there would be a challenge for sure. Do you think a 5.5" liner would be OK, even thought a 6" is recommended?
Another problem is the top of my chimney was built almost even with the top peak of roof. Not to code for sure.
