I have a boiler that is heated by corn that I just installed. I bought the boiler knowing the company was out of business last year, it was brand new. I do not know that much about boilers and I have learned quite a bit in two weeks. One of the problems I have is that the copper coils are now leaking at the bottom of where the coil begins, there is 1 1/2 copper manifold with 6 - 1/2 copper lines. I am trying to find out what type of material would be used to solder/weld these lines to the manifold. It is a grayish/black color material on the lines now. I try using map gas and it did not phase this material, which probably sounds stupid considering the heat that this has to withstand. Any advise would be greatly appreciated. There are pin hole leaks on the 1/2 copper lines near the bottom. I was not aware that I needed to have a constant water supply to the boiler and the water was boiled out inside the boiler and as a result of my stupidity, I am assuming that is what damaged the lines to cause them to start leaking.? I am also assuming that these are type K copper lines. The manifolds are fine, I am hoping to replace the copper lines, once I can learn what material to use to weld these lines.
Thank You
