My trick
There are many thought on burning pine I burn a bunch of it but I do it in an owb . I personally would not burn it in a wood burner inside my house . I know a few people who burn it in a fire place in there house but there is probably a foot thick of concrete in the fire place . I also live in NE PA and I find hard wood all over the place for free. I am not sure where you live in in pa but there are farms all over the place a good source of scrounging hard wood .
My trick to avoid problems with any wood as regards chimney build up is..I STOPPED using a damper decades ago. I adjust my burn with species/size and air intake. When I used a damper all the time, because that was "how everyone does it" I was out there cleaning every month in the winter, etc, same as everyone else. I thought about it one day and just opened it up..learned how to run the thing properly that week, experimenting, then left it open all winter, and removed it entirely and plugged the little rod holes the next summer. Didn't have to clean the pipes again, short of in the summer take them out, knock them a bit, reinstall. I moved my stove out to the yard to cook on in the warmer months anyway, so that was no big deal. Negligible if any soot or buildup.
Since then, no damper. I don't even own a damper. Our brick chimney here has zee-ro flaky stuff, ever, I check every year, and have yet to see any appreciable build up of anything.There's just nothing there to clean. And this is not a super dooper epa turbo charged direct forced air injection system, just an old regular old wood heater.
You car or truck is a heat engine, same as a stove, just has some pistons, but same deal. Does it make any sense at all to put a crimp or restriction in your exhaust pipe? Does it make it run better/cleaner/more power/better mileage? Nope, nope, nope and nope. I've never heard of anyone purposely restricting their exhaust to "improve" anything on any sort of heat engine pump except woodstoves.
I think dampers are "hoop snake" old wive's tales junk science from a hundred years ago and it is so ingrained, even with manufacturers, that you "have" to have a damper, that the practice continues.
Yes, it takes just a little more forethought on loading the stove and adjusting the air for the results you want at any particular time, but that's it. I get all night burns whenever I want, low cool fires, medium fires, infernos max heat, whatever it calls for that day/night.
And it REALLY keeps the chimney clean.
AFAIK, I am the only dude in the known universe who doesn't run a damper on an indoor heater. I would certainly like to hear from anyone else who has tried that for an entire season.
