This site has convinced me to finally install a wood stove, thank you for providing so much insight. After spending countless hours researching I am leaning toward purchasing the Englander 50-TVL17 (40,000BTU). It will be a through the wall installation on the first floor of a double brick 2 story townhouse with natural gas heat as a backup. Both floors are only 400 sq foot each with most of time my spent on the first floor. I'll be firing it up at about 3 o'clock each day after work and I'm usually in bed by 10. Can anyone give me any thoughts on 1) How much warmer will the first floor be as opposed to the second floor? 2) Will the first floor get ridiculously warm? (I'm fine with it, better then freezing) 3) Is it a good idea to fill the firebox before going to bed and adjust to a low burn? 4) Any idea given the size of house and hours stove will be in use any idea of how many cords of wood I'll use from approximatly Oct 15-March 15 in northeast climate, keepinjg the house in the 70's degree range? Last, is it worth to install a chase around the exterior double wall pipe? I can't wait to stop paying the extortionist gas company, thanks for all the info.
