Thank You Dan, Thank You Wallies

I do not even remember when it was that I came to the "WALL" for the first time. Someone (do not remember his name, he was from R.I.) at a Buderus class told me about it. Since then it has been the biggest source of heating info that I have ever found. Three or four Seminars/classes a year on Wirsbo,Viessmann,Tekmar,Buderus, Unico, keep me up to date on the products I sell and install. But the Wall is where I hear and see all the little odds and ends that complete my education, or at least keeps me informed about what is working, and what is not. Thanks Dan, and thanks Wallies, I "Lurk" as someone once said, I see the posts every day, If we all got together for a big bash, they better pad the walls and bring in the beer on a Primary/Secondary system, and the only head we would have to deal with would be the one on the top of our mugs!
