Thermal bridging - stove flue pipe?

ravendude

Hi,

Thinking about installing a wood burning stove into an extension.

Most likely we would have an exposed flue pipe going up from the stove a few feet and out the wall (with a bend), then up the outside of the new flat rooted, 2 story extension. Reason for this is that there would be a bedroom above (maybe going up through the bedroom might be an option).

Obviously given the flue pipe is metal, it would seem you'd have a pretty bad thermal bridge through the wall? Sounds a bit mad to me to be honest?

We would be out at work during the day so plenty of cold hours the stove would not be fired up.

Any thoughts?

double wall insulated flue piping and high heat expanding foam to seal it through the wall, sorted.

Is the outer casing not steel? that acts as a thermal bridge conducting cold from outside to inside, when the stove isn't firing

Too many bends
What about an external chimney, like an isokern from https://www.schiedel.com/uk/
its like lego and has a 60 year life

I have used them, very easy build

That would indeed solve the thermal bridging problem I expect.
I had some thing like this in mind, which surely is a major thermal bridge.
I was assuming flue pipe some thing like this:
