Hi Roger, I did the chemistry on that last year, as I was interested in just how much water was produced. C3H8 + (5)O2 --> (3)CO2 + (4)H2O According to my calculations, a 1lb bottle of propane produces 76 ml of water (less than three ounces), with the remaining byproducts emitted as CO2 gas. See this page for details: http://www.sparknotes.com/testprep/books/sat2/chemistry/ chapter7section3.rhtml A human being exhales 2-4 cups of water per day, depending on the relative humidity. Divide that by 3 (8 hrs sleeping in the westy) and you still get a LOT more water from a human than you do from a propane heater.
