How Your Furnace Works

How Your Furnace Works

Though the presence of a furnace is familiar, homeowners often lack basic knowledge about a furnace. How does it work? What is the difference between a gas and an electric furnace? This article will dispel some of the mystery surrounding furnaces.

First, what is a furnace? A furnace is a heating system that uses either natural gas or electricity to heat your home. The furnace heats air and then uses a blower to circulate the warm air through your home.

There are two types of furnaces: gas and electric. Gas furnaces are powered by natural gas, while electric furnaces are powered by electricity. Both types of furnaces are relatively efficient and can save you money on your energy bill.

How does a gas furnace work?

A furnace essentially consists of a heat source and a blower. The heat source in a gas furnace is a burner that uses natural gas as its fuel, while the heat source in an electric furnace is a set of electric coils. The blower is a device that circulates air throughout the home.

The burner in a gas furnace ignites natural gas that has been piped into the unit. The resulting flame heats a metal heat exchanger. The air from your home’s return vents passes through the heat exchanger, where it picks up heat from the metal. The heated air is then circulated back into your home through a system of supply ducts.

An electric furnace also has a metal heat exchanger, but the coils that make up the heat source are powered by electricity instead of natural gas. As the coils become hot, they heat the air that passes over them in the same way that the burner in a gas furnace does.

In both gas and electric furnaces, the blower circulates the heated air throughout the home. The air is typically forced through a system of supply ducts that lead to registers, which are openings in the floor, walls, or ceiling through which the air enters your living space.

While gas and electric furnaces both have the same basic components and operate in similar ways, there are some key differences between the two. Gas furnaces tend to be more expensive to install than electric furnaces, but they are also typically more efficient. Electric furnaces are easier to maintain than gas furnaces, but they can be more expensive to operate.
