I learnt alot about fire places today.  We had a chimney sweep come and look at our fireplace because every time we opened the door our house would be filled with a huge cloud of smoke.  The guy cracked up when he looked at our Chimney.  It is the worst he had ever seen!  I was so embarrassed, apparently it is just a wood burner and the coal we have been using is just clogging it up.  Oops.  When he swept the Chimney our fireplace was completely packed with soot.  It was BAD!
