I recently built my hearth and hooked up my old Pre EPA stove (HUGE 36" across on top- heavy guage steel - can fit 30" logs). I have been wanting a new stove and have considered Woodstock PH, but the Englander reviews are great and the price is right. But I need reasonably long burn times. Previously I thought I could only get about 7 hours from my stove. But I am getting 8 1/2 hour night burns and it is in the teens here at night right now. Also, I am probably only filling the box half full.....maybe. I haven't tried stacking splits to the brim as I see you guys doing here. I'm getting 8 1/2 hours burning soft cottonwood no less. The stove is too hot to touch in the morning. So here is my issue. I am afraid of buying a smaller stove like the Englander 30 and merely matching my burn times. The Englander would probably burn less wood since it is smaller and efficient but if I can't eek out 10 to 12 hour burns (in 15 degree temps) then why bother? I'm starting to wonder how many hours I could get out of my old beast if I stacked it to the brim, especially if I used a harder wood. (But typically I burn pine) And if I stack to to the brim, I will be burning HUGE amounts of wood. What are you Englander owners getting? I have read 12-14 hours but do you sometimes only get 8 if really cold? Must it be stacked to the brim to get 12 hours and have the planets aligned? PS: Heating rambler with 2200 on main floor.....heating half that much in basement where stove is located. (Bsmnt is 2200 as well but I close doors to other half of basement....storage area, excercise room, fruit room, etc) Stove supplements my furnace. House is 6 yrs old, very well insulated, including basement.
