It's impossible to generate heat from a hydrocarbon and not produce water vapor.
true, but in a vented furnace ALL combustion air AND the water vapor goes out the vent. all that the circulates inside is the existing inside air that goes into the heat exchanger, picks up heat from the heat exchanger hot metal then goes back into the structure. Exhaust gas with water vapor NEVER EVER should enter the structure from a open flame VENTED furnace such as an RV furnace or home furnace.
In a wave heater you will get moisture in the air as a combustion byproduct. When burning propane, slightly less than 1 gallon of water for every gallon of propane burned. now a wave 6 running on high will consume a gallon of propane about 15 hours (90K BTU/gallon). probably several days of use or more in many cases.
X2 ... I'm always annoyed by folks claiming that catalytic heater generate no water vapor. That's against the laws of physics.
