While we're talking about stoves, I've always wondered why people say that burning propane produces a lot of water while wood, for example, is a drying heat. Chemically, the products of any combustion reaction are water and CO2. There's a little better carbon:hydrogen ratio (1:2) in wood sugars that in propane (3:8). Does the difference in those ratios account for all the extra moisture that propane is supposed to produce? Or is water compressed into propane tanks? What's the reasoning behind propane being bad for moisture on a boat?
I may be wrong but I think the confusion is about using your galley stove as a heater as opposed to a designated heater with a chimney.
