You may take heart and connect a metallic container containing water on top of your heating device like heater, stove or the hearth. Please ensure it has no outlet except one pipe on the top which gushes out the vapourized water. Connect this pipe at lower level than the one being heated also ensure that this container is at sufficiently lower temperature than the ones being heated. This helps the water to condense in form of droplets. Much like the atmospheric water condenses on a cold drink can. Chill man!!
