Most people adjust their thermostats regularly, but never think about how that one little change sets your furnace into motion. In fact, many homeowners have no clue how their heater works, and as a result, the might not realize the importance of routine maintenance and repairs. If you would like to educate yourself on the function of your heating system, we encourage you to read on to learn more about how furnaces keep your home warm. 

Different Types of Systems and Fuels

It’s very common for old homes to have furnaces because they are one of the oldest heating systems available to homeowners. When they first started installing them in houses, they used coal and wood, but today, many models use electricity, gas, or propane. Most significantly, the newer versions operate much more efficiently at almost 98% annual fuel utilization efficiency.  As a result, you get more bang for your buck when it comes to purchasing fuel.

Converting Fuel to Heat 

Regardless of which fuel your furnace uses, it still uses forced air heating where the heat is transferred to air and blown through the ductwork and vents of your house. The only thing that differs from fuel type to fuel type is the way in which it creates heat to transfer to the air. With propane and gas furnaces, a pilot light ignites burners in a combustion chamber, and the heat from the burners goes through a heat exchanger before being blown through the ducts.

An electric furnace uses electrical ignition instead of a pilot light. The ignition activates several heating elements with conductive coils, and as the current passes through them, the air is heated for the blower.

Ventilation Systems

After the air is heated and passed on to the blower, it is sent through the ductwork and vents of your home. Most furnaces share ductwork with air conditioning systems so that you don’t have to take up extra space in your house. Regardless of whether your two systems are connected or not, the process doesn’t change. The hair simply flows through the vents into different rooms to provide equal heat distribution throughout your home.
