Hi everyone, I am really late to the party on this one and have to admit that I know nothing about boilers except that the potential energy contained inside one is something that must be understood, and treated with great respect.
I am very curious about copper as the material choice. Cost and strength are a couple of negatives. Aesthetics, heat transfer, and maybe authenticity are a couple of pluses. I know that if I hunted around in previous threads I might find the answer, but it seems like there are some seasoned veterans right here, and I am hoping to learn. And sutty, with your extensive welding background, you could have been working with a material you had lots of experience with, so there must be so good motivation for using copper. There is definitely some good advice in this thread, and I am not at all questioning the material choice, I am just curious.
