Been burning in my 3100 for 6 years now ,i live just north of Pittsburgh pa, with this milder weather I’ve been getting away with 1 or 2 fires a day but if it gets below 25 degrees ill do 3 burns a day, it’ll keep our house in the high 70s sometimes 80 .wife likes it warm ,stove is in corner of basement pointed towards stairwell,unfinished ceilings allow the heat to warm up the whole floor and it radiates up through everything,i came from using an older squire which heated well but you had to feed it every couple of hrs which gets very old .i now have burns going into 8-10-12 hrs depending on outside temperatures . thanks and good day
