I replied to the post about how much wood have you burned so far this season. Well, here it is Dec.5th and I have already gone thru 1and a quarter cords. Insert works like it is supposed to. But we get no sun, while our neighbors are basking in passive solar heat, none here-zilch. Our house sits in the middle of a one and a quarter acre, with 100 year old Douglas Firs and Western Red Cedars surrounding us. We only get the sun in here during May thru August, when we don`t need it.lol I recall going outside middle of Sept and the temp was warmer outside than inside"I`m not kidding". And the big problem that I personally have is that whenever I cut down a tree, the better-half threatens me with horrible consequences. So, long story short, we live in a moderate climate, but probably burn for a longer period than some of you in the colder climates. Guess, it`s all relative though, nice and cool here in the summer-time. Something to think about for those of you maybe involved in building and planning to heat with wood. LEAVE SOME SPACE FOR THE SUN...
