Can you share the mechamism of adding moisture to the air? Heating air allows it to absorb moisture. Air in 45°F 70% RH air out 70°F 30% RH
burning a hydrocarbon yields CO2 and H2O as the byproducts of combustion.
Then there are the trace amounts of NOx and can include CO.
In a VENTED furnace, both exit in the exhaust and never enter the dwelling.
In an UNVENTED device, such as stovetop, oven, wave heater, kerosene heater, both enter the dwelling area.
and yes, the amount of water the air can hold is highly dependent on temperature. a few degrees temperature change can result is a large swing in RH. The amount of water doesn't change (assuming RH<100%) , the amount the air can hold changes.
H20 from burning propane is slightly less than 1 gallon of water for each gallon of propane burned.
