I ended up turning off one tank as it had not started drawing from it yet. And as it worked out, the "in use" tank ran out around midnite. I went out and flipped the regulator lever over, and turned the full tank on. I waited til the net morning to change the empty tank. But I did get a good idea of tank life expectancy. I will keep track of the next tank when it runs out. Then I will get a closer idea of how long they last. I can base refilling empties with that info.

After three pages with this thread, the solution is to try to get a handle as to how long it takes to run out and swap bottles before that happens? :S

That might work as long as the running time is consistent over the days. Suppose you run 2 days, it warms up and you don't run for 2 days, then you have to run 3 days. Or it's warm enough that it only comes on infrequently, then cools down and it runs alot. How are you supposed to get a reliable estimate of how long it will last? Seems to me a way to measure what's in there is much better than a WAG.
