My stove is a vogelzang defender. I have a 6 inch ss flex liner measuring 23 or so ft up existing chimney.im burning dry maple right now i load the stove up as much as i can with such a small firebox around 9pm. I then have to get up around 1 or 2 am to load the stove up again. mostly coals are left. This is with the air shut down as low as it will go. Then im up for work at 5 load up again then im usaully home by 5 pm. I live bout 10 mins from work and i went home at lunch today to stove that had maybe 2-4 coals left. Wasnt my funnest lunch ive had haha would you all just let it die down during day and fire it back up when you get home or would you go home at lunch? the stove works well for my needs since i put the liner and block off plate in. it takes the basement about two hours to get up to 70+ during the cold weather were having right now. What do you think?
