Answer: Well, this is also called a gravity furnace. The gravity furnace works on the principle that warm air rises and cool air falls. These do not depend on blowers to circulate the air through ducts and vents. The air produced by combustion chamber rises through ducts and the cold air falls through ducts that return it to the furnace to be reheated, thus completing the circulation cycle. This is a very old design of furnace and also called the octopus furnace.
