True...I was thinking purely rural/old city (like those 120 GAL tanks) for some reason. I don't have any experience with it, but I'd imagine one could shift that set-up back to woodstove (or in the case of a gas insert fireplace) without too much trouble. You might be wise to look into it just for information's sake, print/write out steps so you'd have it if the need ever arose. Better to have and not need....
