Oversized flue issues?

[dvellone]

I have an opportunity to pick up a used Upland 207 to heat my new construction this Fall/Winter. I believe the 207 requires a 7" flue, but the heater I'll be using permanently will require 8" which I'd install (stainless insulated) in advance for use with the temporary heater. Is the larger diameter flue likely to cause issues with draft with the Upland?

How tall is the chimney going to be?

22' off the top of the stove. 8'of double wall uninsulated on the first floor and insulated the rest of the way up the center to 3' above the ridge.

If the upland is 7" You will be fine put in the 8"

I take it the stack height is what would make it work?

I'm wondering the same thing. I notice that some older stoves had a larger flue requirement while more efficient and larger stoves - like the Jotul 500 - specify a 6 inch flue. I figured the older stoves were exhausting much more heat and gases while the more efficient stoves exhausted much less heat requiring a smaller flue that would be easier to keep warm for good draft.

You got it. Being a taller chimney, you will get more pull, especially since this is double wall inside and then insulated above, good combo.
