Hello.I have an over 100-year-old oak farmhouse with a tin roof. Only insulation is what I put in the ceiling.aprox 900 sqr.ft.Storm windows from the 70's.I've been using an Ashley wood circulator for the last 9 years & it's shot.I'm lost now on what to purchase. I like the north-south type wood loading but can use east-west if the door opens from left to right. Looks don't concern me.I don't think I want the catalytic type. I kinda liked the Drolet Black stag II but can't find a review. I can go as high as $1400.but I don't want too. Your advice on makes & models would be appreciated.
