I appreciate everyones concern about the wood. I have burned wood for 40 years. I know not to burn wet wood. For the first 4 months this year I had wood that had been split and racked for over a year. I do not cut any live trees in the first place. I tend to only cut dead wood that has lost its bark. Most of it is as dry as bowling pins. I have cleaned this boiler every Saturday morning since I have owned it. I will get the tubes polished down this weekend. There is not a creosote build up in the boiler. And I have not chopped up the interior of my boiler yet to see if it has plugged passages. If Pro Fab knows this is a problem, in the new ones do they have acsess ports already in the boilers or do you have to butcher a new boiler. My boiler just does not perform the way it was sold to me., Jim
