How Forced Hot Air Works
A forced hot air heating system uses warm air to heat a building. It moves hot air through ducts to rooms.
The system heats air in a furnace. Then, a fan pushes the warm air through vents.
Components Of The System
The system has several main parts. These include the furnace, blower, ducts, and vents.
- Furnace:Heats the air.
- Blower:Moves the air through the system.
- Ducts:Carry the warm air to rooms.
- Vents:Release the warm air into spaces.
Heat Generation Process
The furnace burns fuel or uses electricity to create heat. This heat warms the air inside the furnace.
Gas, oil, or electric furnaces are common. The heated air is ready to move through the house.
Air Distribution Mechanism
The blower pushes warm air into the ducts. The ducts carry the air to each room in the building.
Vents open to let the warm air inside the rooms. Cooler air returns to the furnace to be heated again.
- Blower moves warm air into ducts.
- Ducts carry air to rooms.
- Vents release warm air.
- Cool air returns to furnace.
