25* here and stove is going cold. It's still nearly 80* in the house from a small load of wood I put in last night (it WAS 7* last night when I loaded it!) Might put in 2-3 pieces at night, but don't need much other than that to keep the house warm. Seems this winter either it gets warm but then the wind kicks in... near impossible to do any work outside, or it's colder then heck... again not fun. I wouldn't mind a couple sunny calm days of 25-30*.
