Today I'm putting four different variations of external flue pipe water heating coils to the test. Three designs were inspired by your comments, while the fourth is something completely new that, to my knowledge, has never been tried before. Unlike my previous tests where I placed copper coils inside the flue, these external designs offer significant advantages: no creosote buildup, no galvanic corrosion between copper and steel, and overall much cleaner and safer.
