The only time I notice is when there's a power outage during winter
and I have my ventless propane heater on, then after about 24 hours I
see condensation on the windows. Otherwise I don't notice any
condensation from propane cooking, in fact with the oven on the
humidity in the house is lower. In mid winter when the temperature
drops well below zero I put on my ventless propane heater along with
the propane furnace, saves on fuel as the furnace doesn't run as
much... ventless heaters are 99% efficient as no heat is lost up a
chimney... and still no condensation, because then the house is more
evenly heated.
