Very effective way to heat water if you use wood or coal heat in a stove. However, the one glaring problem with this set up is safety. It is difficult to control the heat source and these things tend to overheat, so a good safety valve, and a safe place for it to dump is critical. They tend to dump often and waste a lot of heat and energy, but can be used effectively. I had an old Monel tank that we removed just a couple of years ago, so there are still a few out there. If you need some diagrams, I think I may have a few in our old state plumbing code books. Let me know via e-mail and I'll try and look them up for you.
