Good morning. Anyone running a Portage and Main Ultimizer BL28-40? I am very impressed with the answers I got from thier rep and their online videos. I have not seen a unit in person, but in Sept we are hosting the Great Lakes Logging Congress and PM will have a units there. The township where I am moving will allow boilers with permision, I have no neighbors and 11 acres so that shouldn't be an issue. This boiler has a refractory bottom and replaceable water jacket, 20 yr warranty (pro-rated) and just looks like a well made unit.
