If my wood is properly seasoned why would my stove start to cool down rapidly from 500 -600 °F down to 350 ticking its azZ off upon reducing air? Good coal bed and good wood. I originally thought it was the beech since it only seasoned about 8 months this damp summer.So I tried some year and a half seasoned ash and white birch, same result. So now I have some of my BIL's 3 year old mixed hardwood and am getting the same thing. My overnight burns leave me with plenty of coals to restart sometimes too much but the house temps really drop becuz the stove temps drop outta sight when I shut it down It is a convective stove so perhaps I need to add a blower and run the stove with more air? Or a pipe damper to keep the heat in the stove? Or is my draft too poor to pull in the air at a reduced setting? I am just over 16' from floor to chimney cap. straight up off of stove with double wall and through the roof with simpson duravent with about 4' of pipe above the roof peak . I'm getting pretty ticked at the missus walking around going Brrrr.... Brrrr.... This stove is capable of heating 2500 sq foot and I am trying for just over half of that. Also noticed back when it was in the 40's it didn't draft so good as it was hard to get the stovetop up to temp. Thanks for any input ideas.
