First warm/hot air is lighter than cool/cold air. As the fire in the fireplace consumes oxygen from the surrounding air, it is also heating this air. This heated air then rises, and as it rises cooler air is drawn in from the surrounding room. As long as the air in the fireplace is warmer than the air in the room, this process will continue..

∙ 15y agoWarm air rises - in this case smoke and heated air rises up the flue to the roof. As this reduces the pressure around the fireplace it is replaced by air from the room which in turn causes a draught usually along the bottom of the door or round the window. In the good old days when you sat in front of a fire you could be roasted on one side whilst being chilled to the bone by the draught on the other, but at least the room was well ventilated.
Passive ventilation systems operate on the same principles (without a fire) as the warm air in a room will naturally rise: the consumption of oxygen is of rather secondary concern, as it is only a small component of air.

Why do you need to sleep in a well ventilated room?
- Sleeping in a well-ventilated room and in an isolated room may affect one's respiration. Poor air circulation may give difficulty in breathing process while having proper air ventilation may give proper inhalation and expiration.
How to Calculate gas fire size for room?
Volume of room in square feet * 0.0015
Why lighted oven should not be kept in room especially in a closed room?
A gas oven burns oxygen and if not properly ventilated can cause a decrease of oxygen and an increase of carbon dioxide in the room. Carbon dioxide is odorless and can kill you.
Does an air soft gas gun need gas to fire?

Why is engine room of ships isolated in case of fire in engine room?
The engine room is designed so it can be sealed off completely in case of fire, in order to: 1. Prevent the fire from spreading to other areas. 2. Starve the fire of oxygen. 3. Be able to pump in and maintain a fire fighting gas such as CO2 (which smothers it) or Halon (which inhibits combustion).
How is gas made from?
gas and fire fire is made for gas gas is the name of the fire
Why should lead acid battery used in ups system stored in a ventilated room?

Can you store gas in the attic?
Storing gas in the attic is not recommended due to the potential risks involved. The attic can have fluctuating temperatures and poor ventilation, which can lead to the buildup of flammable vapors and increase the risk of fire or explosion. It is best to store gas in a well-ventilated, cool, and dry area, such as a dedicated storage shed or garage.
