I have heated my house for 8yrs. 2 seasons ago I acquired an old Nashua off a neighbor. Nice stove and really pours out the heat. Problem is creosote. Its only the dry flaky kind but with the old stove I could keep the stove pipe and chimney hot enough to keep it burned out. With this old technology its so efficient I can't get stove pipe hot even with the stove top temps as high as 700 degrees. The old stove basically only ran about 100 degrees surface temp cooler than stove top temp. The delta on the Nashua is huge. I'm guessing the flue temp is obviously low but how can I raise it? I don't want to go above 700 on the stove as most might say that is overfiring as it is. My normal stove top temp is 500.
