I have an exterior masonry chimney of 35-40' tall. It gets hit with NW weather, including winds. It's fed from the basement via wood furnace. The wood furnace sits next to an oil furnace that has been disconnected some time ago. The PO installed an ovalized flexible liner, inside the 7x8'', when he put in the wood furnace. He half assed the termination at the top and that's why it needs replacement. His piss poor work caused it to rupture about 2' down. There's only 1 flue in this chimney, hence the dormant oil furnace. Only it's blower is used for the forced hot air.
We set up scaffold today to comfortably rebuild and repoint the top of the chimney. Top 3 courses are missing/loose. The remaining chimney, above the roof line, will be repointed. My future plans are to install an outdoor gasifier furnace. At this point I'll be pulling the indoor furnace out of service, and want to be able to install an oil boiler in the basement for backup heat using the same flue.
@bholler these are where my questions lay. My house is 4500sq ft and both current furnaces, oil and wood, are rated for 200k BTU each. They both have an 8'' flue. I'm assuming I should knock out the clay liner and install an insulated smooth wall SS liner? Will it fit? If I remember correctly there are different grades of SS that will handle both wood and oil?....no, I will not be running both through the same flue. I just want to replace the liner once, now, and correctly.
I'm looking to be educated on this better. My local chimney guy will get the nod. He's earned a good reputation. I'd like to be on the same page with him when i'm ready for the liner.
TIA for any answers and advice you choose to assist with.
