Any thoughts here?

If the stove has a rear vent, are there any concerns with running the pipe up the chimney?

Do you insulate/block the air flow around the pipe inside the chimney with something heat resistant / fireproof?

What can go wrong....

We're talking a masonry chimney? There are stainless steel liners made for connecting to a wood stove used as an insert in a old fireplace.

I installed a wood stove this way with a stainless liner and have not had any problems. The masonry chimney had a good clay liner. The stove works great. Did not bock airflow around the pipe with anything but use it hardly ever in winter as place is not insulated.

I would suggest that you check out if you’re woodstove is an airtight stove. They have a damper that controls air to the firebox or fire. If you have an open draft from the fireplace that can draw air it could effect how your wood stove works.

Any one that uses a wood stove i highly recommend you put an outside air kit on it. It pulls in outside air for combustion and not from the living space.

The chimney and fireplace at my cabin had deteriorated quite a bit. The metal liner and heatilator conduits in the fireplace were rusted and the masonry chimney liner and blockwork was crumbling in places.

I repaired the blockwork, installed a stainless steel flue liner, blocked the heatilator vents with stonework and installed a wood burning insert.
I can get an 8 to 9 hour burn with hardwood if I manage the insert correctly.

I also highly recommend getting a blower. It puts out much more heat into the house.
