I was told it was a hard wood the wood was delivered. At the time it was heavy. It's been drying for 1.5 years. I was told oak or maple. Now it's not so heavy. The darn wood burns so fast. In 1 to 2 hours it goes from splits to coals. Either way, if I stuff the box or do twosies. I get great heat but goes so fast. Why do you think? Is this common? I wait till box get up to 500 degrees before shutting down.. Also, should I post here or in Wood Stove forum? Thanks in advance.
