How Central Heating/Furnaces Work

Central heating systems rely on a furnace to generate heat and distribute it throughout your home. While the basic principle remains the same, heating air and circulating it via ducts the way each type of furnace works can differ depending on the fuel used. Here’s a breakdown of how each type of furnace operates:

Gas Furnaces

Gas furnaces burn natural gas to generate heat. The process starts when gas is ignited in the burner, and the heat exchanger transfers the heat to the air. The blower fan then circulates the warm air throughout the home. Gas furnaces are the most common choice due to their energy efficiency, often providing 80-98% efficiency. They are typically cheaper to operate than electric or oil furnaces, especially in areas where natural gas is readily available.

Electric Furnaces

Electric furnaces use electric coils to generate heat. When electricity flows through the coils, they heat up, and a blower fan distributes the warm air. These furnaces are typically more expensive to run, especially in regions with high electricity costs. However, they are simpler to install and require no fuel supply other than electricity, making them a good option for smaller homes or areas without access to gas or oil. Installation costs for electric furnaces range from $1,500 to $3,500.

Oil Furnaces

Oil furnaces burn oil to create heat. Similar to gas furnaces, the heat generated is transferred through a heat exchanger and circulated through ducts. Oil furnaces are less common than gas but still used in some areas where natural gas is not available. They can be more expensive to maintain due to the cost of oil and the need for regular cleaning. Oil furnaces are typically more costly to install, with prices ranging from $3,000 to $7,000.
