Where is the fan in that pic?
All that brick will suck up a TON of heat. Very much especially if that brick is connected to the outdoors.
As others have mentioned - if that pipe temp is really the surface temp of double wall pipe as you say, you are burning waaaay hot. Typically single wall internal temps will be way more, maybe double, than what surface temp is. Double wall would be waaay more again. But maybe there is something still uncertain here?
Square footage heating ratings for stoves are most always pretty hokey. But in this case, the stove is behind an extra 8 ball with what is being asked of it and how it was installed.
I will add that I think pulling the ceiling insulation did help. But no doubt getting more heat up there could be improved on somehow. Usually with strategically placed fan plus maybe a couple of floor vents. Vents on their own should not increase noise all that much - just don't put them where the kids sleep if noise is really a big issue.
Also, 5-6 cords for the whole winter is not really THAT bad.
