This was thje first yr. buring with my P.E spectrum classic.. When we bought the stove we had no expectaions of it heating our upstairs, we just wanted it for our finished basement which is very cold even in the summer without a/c.. we bascially were not using the gameroom in the winter which is a large area where I like . Our house is a large raised ranch 2500 sq. ft. built like a maze. But we have been suprised at the amount of heat making upstairs with nothing but leaving the door open, so next year might make and effort to move the heat upstairs to help.....The stove has definetly went beyond our expectations..both with the heat output and the overnight burns ease of start ups etc... Ive had always had fireplaces but this is the first woodburner and I am amazed at the differences, we have a fireplace the first floor which is open on both ends not really for heat but nice to have. The stove was installed by a local dealer ..Thanks for looking, Pez
