You are right on. Heating to "remove" moisture is not quite the right term. If you heat air then the relative humidity in per-cent will decrease. Thus it will "feel" like moisture has been removed. Cool that same air back down and you will be exactly where you started in terms of humidity.
Relative humidity is a measure of how "saturated" the air is and is directly related to the temperature of the air. Warmer air can "hold" more water (in terms of volume) than cooler air. Thus given the same volume of water in the same volume of air if heated the % will drop and if cooled the % will increase. If cooled too much - below the "dew point" - we have rain. It is the % that we "feel" as humidity.
