So today I stop to see a local farmer , to ask him if he has ever seen a stainless milk tank kicking around. No he says but I got a farmers mag with some classifieds in it .Well no tanks but I found a adv. for Switzers wood burning system. The ad shows a boiler a little Garn like. So I called and left a message (no web) Don't you know he called me back in an hour. been building them since the 80's. Its a pressurized unit. I talked to him for a hour and was very impressed with everything he said. Then I called a guy with one about a half hour away that he gave as a reference ,and I'm going to check it out Monday night. Amazing, goes to show not everything is on the net. Has anyone ever heard of this unit. Scott
