The details: Blaze King Princess Insert Norwalk, CT: http://www.weather.com/weather/wxclimatology/monthly/graph/06854 1974 sq. ft., one story ranch built in 1957. Avg insulation. House layout: & I intend to burn 24/7 during the burning season. Wood will be mixture of Maple species and Oak (will try to set Oak aside as I come across it) I intend to keep the house in the low 70s, maybe mid? Keep in mind I'm a newb and I'm sure I'll screw up quite a bit while learning. Winner = closest cordage # (to the nearest 1/4 cord) w/out going over. What's the prize if u guess how much wood I go through including the shoulder seasons? Well your pic...either: "a nice sample of wood pieces from my lovely wood pile" or "gently used, broken axe handle" Good luck competitors!
