re: Saw dust

I read a blog somewhere by a guy telling about when he was a young apprentice working in a woodshop. His first duty in the morning was to fill up this barrel sawdust oven from the sawdust created the day before. He tamped it into the barrel, etc. like in the video and got it lit. He said it kept the whole shop warm all day and it didn’t cost anything, plus they got the sawdust removed. I seem to remember that several guys worked there, so it must have been a fairly large shop. Personally I would be afraid to use something like this here in Norway because everything is so highly regulated and I wouldn’t want to break any laws or cancel out my insurance. Besides, I recently installed a heat pump system that is quite economical and keeps the temperature in the shop just right. We had it in our living room before that, but it made a whiny noise that I couldn’t hear, that really irritated my wife (she can hear high pitched sounds that most can’t), so we changed it out with a better, more quiet unit and now we are both happier!
