This is my improvised twin wall flue for the above.

It's a baked bean tin with a 25mm hole in the end. I will bend a couple of tabs to secure it in the timber wall.
I'm not sure what your exhaust pipe diameter is
I drilled a larger hole in the wood and then attached metal plates on either side of the wood with exhaust pipe sized holes drilled in the centre - has been running fine like that for a few years.
Have you ever taken one of the plates off to check for charring?
If you over cool an exhaust you will get slower gas flow and effect performance also i crease the risk of rapid corrosion.Why waste that heat
Been thinking of a small heat exchanger for hot water, 1gallon ss tank convection circulation, did it on abiger scale with a wast oil burner flue 10 gal tank had to add cold after hour or so
Why waste that
