Nonetheless, their flexibility and ease of installation make electric furnaces a unique and practical heating solution for certain homes and situations.
How does an oil furnace work?
An oil furnace operates by burning heating oil to generate heat. The process begins with the oil being stored in a tank, which is then pumped into the furnace. An electric spark or burner inside the furnace sprays the oil into a combustion chamber. This ignition creates a flame that heats up the heat exchanger.
A blower fan blows air across the heat exchanger as it warms up, transferring heat from the exchanger to the air. The heated air is then distributed throughout the home via ductwork and vents. The combustion gases produced during the burning process are vented out through a flue or chimney.
To ensure safety and efficiency, oil furnaces require regular maintenance, including filter changes, fuel delivery, and cleaning of the combustion chamber and heat exchanger.
Which type of furnace is more energy efficient?
| Furnace Type | Efficiency | Operating Cost |
|---|---|---|
